Introduction

This document is a guideline for a basic install of Apache's web server version 2.2.2 and the Tomcat java servlet version 5.5.17 and integrating it with your current OES Linux setup. A proof of concept and feasibility test that the latest Apache and Tomcat versions would integrate with iManager, Virtual Office, and Remote Manager was required before implementation on production servers. This article assumes that you already have a good understanding of the Linux operating system, command structure and are comfortable moving about inside the environment. If you are not, it is suggested that you obtain assistance during the install or stop and review Linux system administration.

Opinions, Narratives, Flames, Comments and Suggestions

The greatest thing about Linux is its ability to be customized. There is more than one-way to accomplish your desired result and many opinions abound about how to accomplish said result. Although being an avid fan and proponent of Linux, as well as having worked with it since late 2000, no claims of being a guru or expert are made, rather I enjoy Linux for the sake of the fact that it allows me to experiment and learn about computers. I heartily welcome comments and suggestions as well as opinions.

Nitty-Gritty

An out of the box installation of Novell OES SP2 generally includes Apache 2.0.49, Tomcat 4.1.31 and Sun Java2 1.4.2. As further enhancements are made and new features are developed you might find yourself in a position where you desire to install the latest Apache web server and Tomcat servlet container. I found myself in that very situation when it was requested to develop a proof of concept and feasibility test to find out if the latest Apache and Tomcat versions would successfully integrate with iManager, Virtual Office, and Remote Manager utilizing the company's current OES settings.

First things first is to download Apache 2.2.2:

http://httpd.apache.org/download.cgi

Pick the httpd-2.2.2.tar.gz (or bz2 depending on preference of compression tool) and download it to your home directory.

Do the same thing for Tomcat by downloading version 5.5.17 and the Tomcat connectors from:

http://tomcat.apache.org/download-55.cgi

Under the "Binary Distributions" you will see several sections such as Core, Developer, Embedded etc. Choose the tar.gz file under "Core" and download it to your home directory.

http://tomcat.apache.org/download-connectors.cgi

Under the "KEYS" section download the Source JK 1.2.15 Source Release tar.gz file to your home directory.

I chose not to upgrade for several reasons. The first being since this was a proof of concept I wanted to control the test right from the start. Making modifications to the existing Apache configuration could have complicated the process by introducing unwanted elements such as broken symbolic links and/or module errors. The other being, and this is a personal preference, I am not particularly fond of the default Apache 2.0.49 and Tomcat 4.1.31 configuration in OES. Here is why:

Too many directory locations.

Before the flames start on why or why not that is a superior set up, I can only say that some people like the modular approach to Apache with multiple locations and configuration files, however I do not. I prefer what I consider a more streamlined approach of one-control directory. I also find it is easier for another administrator to come in behind me and have an easier learning curve of how the system is configured.

Installation

Apache 2.2.2

*Note* When building from source files some administrators like to work out of the /usr/local/src directory. They can keep track of files that have been built from source and installed to the server. From the standpoint of the author I chose to install and compile from within my home directory since this was a test box and would ultimately be re-imaged. Generally I prefer to use /usr/local/src.

The first thing to do is to perform the checksum on your Apache download. Next to each file is posted the MD5 sum link that provides the checksum. You want to compare to make sure your file is not corrupted nor was injected with anything during download. Open up a console and if you are not already root become so now by issuing the command:

# su

Enter root's password and then navigate to the directory where you downloaded your Apache file.

Then issue:

# md5sum httpd-2.2.2.tar.gz

Upon hitting enter you should be presented with the checksum of:

a0d9f7f6f70110a5965340eb7f3a3e66 httpd-2.2.2.tar.gz

If your numbers don't match download the file again.

Next we need to expand the file for access:

# tar -zxvf httpd-2.2.2.tar.gz

The -v flag is not necessary, however by personal preference I like to see things verbose. Once it has completed extracting the file, change into the httpd directory. We will now compile Apache for our system. I chose to install Apache into /usr/local/apache2. Again this is just a preference. You can build your directory wherever you would like by substituting your location for mine. Be careful that your directory exists before compiling. Apache will not create the directory; rather it will just dump its content in the parent. The compiling and install time will vary depending on the power of your processor and available memory. Expect 1-3 minutes. Execute the following commands to build Apache.

# mkdir /usr/local/apache2                       <- my directory had not been created yet 
# cd httpd-2.2.2                                 <- change into the expanded directory
# ./configure --prefix=/usr/local/apache2        <- configures apache 
# make                                           <- compiles 
# make install                                   <- installs
# make clean                                     <- post install clean up (optional. but good habit)

Congratulations! Apache is now installed on your system. Now it's time to install Tomcat.

Tomcat 5.5.17

Just as we did with Apache we want to make certain we have a good copy of Tomcat. Run the md5sum command against the compressed file to compare checksum numbers.

# md5sum apache-tomcat-5.5.17.tar.gz

Upon hitting enter you should be presented with the checksum of:

994d39c0d2f462c79288e0249991dd49 *apache-tomcat-5.5.17.tar.gz

If your numbers don't match download the file again.

Next we need to expand the file for access:

# tar -zxvf apache-tomcat-5.5.17.tar.gz

Again, the -v flag is not necessary, just a preference. The nice thing about the core binary file is that you do not have to compile and build anything. Once you have extracted the file move the directory from your home to a directory of choice. Again, I chose to install into /usr/local/. For simplicity I called my directory tomcat5 instead of making symbolic links to just "tomcat" because I still have tomcat4 installed on the server and wanted to distinguish between the two of them. Your server environment may differ and you might want to use symbolic links instead.

# mv apache-tomcat-5.5.17/  /usr/local/tomcat5

Your Tomcat files are now located in /usr/local/tomcat5. Next up is to compile the Tomcat/Jakarta connector for the new Apache.

Tomcat 5.5.17 Connector

Here Apache.org throws a curve ball. They don't issue a MD5 checksum. They instead have given a PGP signature. To check the validity of the signature you will need to create the asc file. When you click on the PGP link it will present you with the signature. Copy the text and write it out to a text file in the same directory where your downloaded the connector file. Name it jakarta-tomcat-connectors-1.2.15-src.tar.gz.asc. Once you have done that issue the command:

# gpg --verify jakarta-tomcat-connectors-1.2.15-src.tar.gz.asc jakarta-tomcat-connectors-1.2.15-src.tar.gz

Once you are satisfied that the file is good, the formula is very similar to the installation of Apache. Since we are only going to build the Apache module we don't need to worry about creating a new directory.

Expand the file for access:

# tar -zxvf jakarta-tomcat-connectors-1.2.15-src.tar.gz

Once it has expanded we need to change down into the native directory and compile the Jakarta module for Apache. Following the commands below will build the appropriate module.

# cd jakarta-tomcat-connectors-1.2.15-src/jk/native <- change into the native directory
# ./buildconf.sh    <- configures libtool (for developers or if you have a custom libtool setup) 
# ./configures --with-apxs=/usr/local/apache2/bin/apxs   <- compiles the connector
# make install                                           <- installs
# make clean                                             <- post install clean up

The connector will be built and written as a file called mod_jk.so into the directory <CONNECTOR_HOME>/jk/native/apache2.0. All that is left is to copy mod_jk.so into your modules directory of apache: /usr/local/apache2/modules.

# cp <CONNECTOR_HOME>/jk/native/apache2.0 /usr/local/apache2/modules

Congratulations! You have completed the install of Tomcat 5.5.17. Let's move on to the configuration of it all.

Configuration - Apache 2.2.2

The configuration of the two software components and building the necessary configuration files is a bit more time consuming. My drink of choice for a quick jolt of caffeine is RC Cola. The RC stands for Royal Crown for those of you who aren't from the south. Sweet nectar. Anyways, now is a good time to grab you a jolt of caffeine as we set off to configure the new setup.

httpd.conf

If you are familiar with Apache you know that it reads its settings from the configuration file httpd.conf. There are two methods to implementing httpd. One is modular and the other is monolithic. Just as in use of Linux distributions everyone's opinion differs as to which way is superior and why. I tend to lean towards making a hybrid of the two. I prefer one main Apache config file for the major components of the web server (main server settings, root directory, cgi-bin, modules etc?) and then use add-in conf files for specific tweaks such as aliases. That is the method we'll employ for getting Apache and Tomcat to work in harmony with each other as well as interacting with iManager, Virtual Office and Remote Manager.

Using your favorite text editor open /usr/local/apache2/conf/httpd.conf. I have truncated the conf file to give you a general idea of the location of each line that needs to be modified. Locate each line that is listed below and make the following changes, adjusting your settings to your server environment. Items in bold are the lines you are looking to manipulate and that which is listed between { } are items specific to your server environment.

# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.

ServerRoot "/usr/local/apache2" 

# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
-------------------------------------------------------------------------------------------
Listen {IP address of your server}:80

# Dynamic Shared Object (DSO) Support
# To be able to use the functionality of a module which was built as a DSO you
# have to place corresponding `LoadModule' lines at this location so the
# directives contained in it are actually available _before_ they are used.

LoadModule jk_module modules/mod_jk.so
 -------------------------------------------------------------------------------------------
# ServerAdmin: Your address, where problems with the server should be
# e-mailed.  This address appears on some server-generated pages, such
# as error documents.  e.g. admin@your-domain.com

ServerAdmin {administrator's email}@{domain} 
-------------------------------------------------------------------------------------------
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.

ServerName {IP address of your server}:80
-------------------------------------------------------------------------------------------

# DocumentRoot: The directory out of which you will serve your
# documents. By default, all requests are taken from this directory, but
# symbolic links and aliases may be used to point to other locations.

DocumentRoot "/usr/local/apache2/htdocs"
-------------------------------------------------------------------------------------------
# This should be changed to whatever you set DocumentRoot to.
#
<Directory "/usr/local/apache2/htdocs">
--------------------------------------------------------------------------------------------
# ScriptAlias: This controls which directories contain server scripts. 
# The same rules about trailing "/" apply to ScriptAlias directives as to Alias.

ScriptAlias /cgi-bin/ "/usr/local/apache2/cgi-bin/"
--------------------------------------------------------------------------------------------
# "/usr/local/apache2/cgi-bin" should be changed to wherever your ScriptAliased
# CGI directory exists, if you have that configured.

<Directory "/usr/local/apache2/cgi-bin">
--------------------------------------------------------------------------------------------
# Supplemental configuration
#
# The configuration files in the conf/extra/ directory can be 
# included to add extra features or to modify the default configuration of 
# the server, or you may simply copy their contents here and change as 
# necessary.

Include conf/mod_jk.conf
Include conf/welcome-Apache.conf
Include conf/nps-Apache.conf
Include conf/vo-Apache.conf

Save the file back to /usr/local/apache2/conf/httpd.conf. You may have noticed at the end we added some include lines with 4 more "confs". These are the alias redirects and the Jakarta module property files. They need to be created and saved in /usr/local/apache2/conf/ for Apache to reference. Again utilizing your text editor create the following files:

mod_jk.conf

The mod_jk.conf file sets parameters for the Jakarta module you compiled earlier. It sets where to find the workers.properties file (you will create this later in the Tomcat configuration section), a log file and what level of output should be written to the log file.

# mod_jk.conf
# Set required file locations

JkWorkersFile "/usr/local/apache2/conf/workers.properties"
JkLogFile "/usr/local/apache2/logs/mod_jk.log"
JkLogLevel error

welcome-Apache.conf

This conf file creates the alias redirect for the Novell Welcome Page that is included in an OES distribution. The welcome page gives you a general overview of OES and its capabilities. Although not necessary it is good practice for configuration purposes. (Boy that last sentence sound academic doesn't it?)

# welcome-Apache.conf
# Please include this file in the Apache httpd.conf file

JkMount /welcome/*.jsp ajp13
JkMount /welcome/WelcomePage ajp13
JkMount /welcome/LoginPage ajp13
JkMount /welcome/Header ajp13

Alias /welcome "/usr/local/tomcat5/webapps/welcome"

# In general, allow access.
<Directory "/usr/local/tomcat5/webapps/welcome">    
    Options Multiviews FollowSymLinks
    Order allow,deny

<Location "/welcome/META-INF/">
    deny from all
</Location>

AddCharset utf-8 .utf8
AddLanguage en .en
AddHandler type-map var

nps-Apache.conf

The nps-Apache file creates the alias redirect for Novell's iManager on your OES server.

# nps-Apache.conf
# Please include this file in the Apache httpd.conf file

JkMount /nps/*.jsp ajp13
JkMount /nps/servlet/* ajp13
JkMount /nps/portal/services/* ajp13

Alias /nps "/usr/local/tomcat5/webapps/nps"

#<Directory "/usr/local/tomcat5/webapps">

    Order allow,deny
    deny from all
</Directory>

<Location "/nps/META-INF/">
    deny from all
</Location>

vo-Apache.conf

As you may have guessed, this file will create the alias redirect for Novell's Virtual Office on your OES server.

# vo-Apache.conf
# Please include this file in the Apache httpd.conf file

JkMount /vo/*.jsp ajp13
JkMount /vo/servlet/* ajp13
JkMount /vo/portal/services/* ajp13

Alias /vo "/usr/local/tomcat5/webapps/vo"

# In general, allow access.

<Directory "/usr/local/tomcat5/webapps/vo/META-INF/">
Order allow,deny
deny from all
</Directory>

<Location "/vo/META-INF/">

</Location>

Once you have created these files you have successfully configured Apache. Next up is to configure a few files for Tomcat.

Configuration - Tomcat 5.5.17

There are four files that we need to configure for our Tomcat setup. Catalina.sh, server.xml, workers.properties and tomcat_users.xml.

catalina.sh

# -----------------------------------------------------------------------------

Two aspects about Catalina. You may or may not need to add the JAVA_OPTS Xmx256M comment. The test server in use was near capacity on memory demands and I found I needed to specifically allocate memory settings. You may or may not have to do this depending on your hardware. You'll notice at the end comments are added as well as an LD_LIBRARY_PATH export. This is necessary for iManager to know where to pull resources when you attempt to access it using your new Tomcat 5.5.17 setup. Note! If you do not add and export you get the classic iManager error where you are presented with a login screen but after authenticating it renders a blank screen.

server.xml

The server file looks more complicated than it actually is. It basically configures Tomcat to listen on ports for requests and tells it how to handle these requests. Items in bold need to be configured in /usr/local/tomcat5/conf/server.xml. You will notice that I have changed my connector port to 11009 (which is also reflected in workers.properties). There are two reasons I modified the port would connect on. First, Remote Manager redirects to port 8009. I didn't want a conflict between applications. The second was I am experimenting with setting up load balancing using two instances of Tomcat on one server. You can set your connector to whatever desired non-conflicting port.

<!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
<Connector port="8080" maxHttpHeaderSize="8192"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true"/>
<!-- Note : To disable connection timeouts, set connectionTimeout value
to 0 -->

<!-- Note : To use gzip compression you could set the following properties :

compression="on"
compressionMinSize="2048"
noCompressionUserAgents="gozilla, traviata"
compressableMimeType="text/html,text/xml"
-->

<!-- Define a SSL HTTP/1.1 Connector on port 8443 -->

<Connector port="8443" maxHttpHeaderSize="8192"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" disableUploadTimeout="true"
acceptCount="100" scheme="https" secure="true"
clientAuth="false" sslProtocol="TLS" />


<!-- Define an AJP 1.3 Connector on port 8009 -->
<Connector port="11009"
enableLookups="false" redirectPort="8443" protocol="AJP/1.3" />

<!-- An Engine represents the entry point (within Catalina) that processes
every request.  The Engine implementation for Tomcat stand alone
analyzes the HTTP headers included with the request, and passes them
on to the appropriate Host (virtual host). -->

<!-- You should set jvmRoute to support load-balancing via AJP ie :
<Engine name="Standalone" defaultHost="localhost" jvmRoute="ajp13">
-->

workers.properties

This file, although small, is essential for proper Tomcatting. A worker is the actual go between for requests made to the web server for a servlet. When Tomcat hears the request for an application it is the worker that handles the execution of the servlet. If you remember from our Apache configuration we had created the Jakarta module that included the location of workers.properties. All that is needed is to create this file and save it into /usr/local/apache2/conf/.

#
# Tomcat 5.5.17 workers properties
#

# In Unix, we use forward slashes:
ps=/

# List the workers by name:

worker.list=ajp13
workers.tomcat_home=/usr/local/tomcat5
workers.java_home=/usr/lib/SunJava2-1.4.2

# Tomcat instance using ajpv13 protocol

worker.ajp13.port=11009
worker.ajp13.host=localhost
worker.ajp13.type=ajp13

tomcat_users.xml

This file is not necessary for the implementation of Apache 2.2.2 and Tomcat 5.5.17. Depending upon your security policies, whether you are an uber-administrator or just curious, you may or may want to use it. This file will set permission levels to access the Tomcat server management from <ip address of server>:8080. If you chose to comment out the access in your server.xml file then this file is moot. I included it in this article because I used Tomcat's manager to monitor and test applications and my test server was in a self-contained isolated lab network. You can customize it to your needs and save it in /usr/local/tomcat/conf/. I added an administrator account. If you do choose to use this file I highly suggest you make sure that root owns the file and group as well as execute chmod 600 on the file as it stores passwords in clear text.

<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
<role rolename="tomcat"/>
<role rolename="role1"/>
<role rolename="manager"/>
<user username="tomcat" password="tomcat" roles="tomcat"/>
<user username="role1" password="tomcat" roles="role1"/>
<user username="both" password="tomcat" roles="tomcat,role1"/>
<user username="admin" password="<insert your password>" roles="manager"/>
</tomcat-users>

There is only one more thing to modify. The goal when I started out was to install the latest versions of Apache and Tomcat and integrate their use with the current setup of our Novell OES (SUSE) server. It was not desired to have to edit XML, HTML and other conf files to achieve a successful implementation. Rather, I wanted to substitute the new install for the old and leave the rest of the server setup alone. To accomplish this you will need to create soft links inside your Tomcat 5 directory to point back to your existing webapps.

Do this by changing into the /usr/local/tomcat5/webapps and issue the following commands:

# ln -s /var/opt/novell/tomcat4/webapps/nps nps

# ln -s /var/opt/novell/tomcat4/webapps/vo vo

# ln -s /var/opt/novell/tomcat4/webapps/welcome welcome

Congratulations are again in order as you have just completed the installation and configuration of Apache 2.2.2 and Tomcat 5.5.17! Now it is time to test our work and see the results.

Testing

Start services

Since this is a default load of Novell OES SP2 Tomcat 4.1.31 and Apache 2.0.49 are installed with a start script in /etc/init.d/ that starts the service upon a successful boot. If these are currently running stop them now by executing:

# /etc/init.d/novell-tomcat4 stop

# /etc/init.d/apache2 stop

Next it is time to start our new services for testing. Always start Tomcat first. When you start Tomcat you will be presented with some dialogue, which is presented below the command. Apache will return nothing if it was successful.

# /usr/local/tomcat5/bin/catalina.sh start
Using CATALINA_BASE:  /usr/local/tomcat5
Using CATALINA_HOME:  /usr/local/tomcat5
Using CATALINA_TMPDIR:  /usr/local/tomcat5/temp

# /usr/local/apache2/bin/apachectl start

Apache 2.2.2

Open up a browser of choice and enter http://<ip address of server>. You should be presented with the default Apache index page:

(Figure 1 - Apache default web page running)

Tomcat 5.5.17

Next let's check Tomcat by entering http://<ip address of server>:8080. You should find yourself looking into the face of a tiger that drank sour milk.

(Figure 2 - Tomcat 5.5.17 default web page running)

If you configured the tomcat_users.xml file you can click on "Tomcat Manager" under the administration block and enter your username/password to access the administrator's web page. See Figure 3 for a screenshot of the backend.

(Figure 3 - Administration page of Tomcat 5.5.17)

Now that we have confirmed that both services are running we can check to see if we are able to access Remote Manager, Welcome Page, iManager and Virtual Office.

Remote Manager

To confirm we still have Remote Manager capability with our server enter http://< ip address of server>:8008. It should redirect over to https on port 8009 automatically and you will be presented with Figure 4.

(Figure 4 - Remote Manager login screen)

Log in and you will see Figure 5.

(Figure 5 - Remote Manager home page)

Welcome Page

Although the Welcome Page is not a necessity, since we set it up it is a good test for the installs because it uses a mixture of java and html. Go ahead and access the Welcome Page using your alias: http://<ip address of server>/welcome (see Figure 6)

(Figure 6 - Welcome Page)

iManager

Access iManager via the alias redirect you built in nps-Apache.conf by entering: http://<ip address of server>/nps. Depending upon your server's process and memory it may take a second or two to call up, however your browser should reveal a login screen (see Figure 7).

(Figure 7 - Novell iManager login portal)

To test if your library was exported correctly from catalina.sh, login and reveal Figure 8.

(Figure 8 - Novell iManager main screen)

Virtual Office

Virtual Office access is very similar to iManager. Enter http://<ip address of server>/vo in the address bar. You will be presented with the login portal (Figure 9) and upon access with your credentials you will find yourself on the home page (Figure 10).

(Figure 9 - Virtual Office login portal)

(Figure 10 - Virtual Office home page)

For those with eagle eyes you will see I have a message of "service unavailable" on the home page of Virtual Office. It is referencing eGuide which was not installed on my test server so that error was expected.

Post-Install and Afterthoughts

Congratulations?your server is now configured with a basic install of Apache 2.2.2 and Tomcat 5.5.17 utilizing Sun Java2 1.4.2!

If you intend to migrate your system to the new install of Apache and Tomcat you should go ahead and modify the /etc/init.d scripts to no longer reference and start the older Tomcat4 and Apache services. It is good practice to not just delete the older services in case you find production applications that for one reason or another are not supported by the latest and greatest install that you just performed. Leave the older versions intact and in place until you are satisfied that your system is stable. A good way to accomplish this is to use chkconfig to turn off the older services in all runlevels and then add your new ones to runlevel 3 and 5. No other major thoughts?hopefully this guide is more of a help then a hindrance and your install went smoothly.
