How to install Tomcat on Fedora | CentOS | RedHat

As in previous post we discussed on Tomcat installation, Now we are going to integrate Tomcat with Apache.

# Installing and configuring mod_jk

To make connection between Tomcat and Apache, you will need to download and install mod_jk connector.

I chose to download the current source from the Apache archives:- http://archive.apache.org/dist/jakarta/tomcat-connectors/jk/source/jk-1.2.15/

[root@map007 /]# cd /usr/local

[root@map007 local]# wget http://archive.apache.org/dist/jakarta/tomcat-connectors/jk/source/jk-1.2.15/jakarta-tomcat-connectors-1.2.15-src.tar.gz

[root@map007 local]# tar -zxvf jakarta-tomcat-connectors-1.2.15-src.tar.gz

Change to the /usr/local/jakarta-tomcat-connectors-1.2.15-src/jk/native directory.

[root@map007 local]# cd jakarta-tomcat-connectors-1.2.15-src/jk/native

Now you are ready to create the custom configure file for your system. Execute the following:

[root@map007 local]# ./buildconf.sh

[root@map007 local]# ./configure –with-apxs=/usr/bin/apxs2

Now build the mod_jk with the following:

[root@map007 local]# make

Finally, if you were successful with the previous commands, copy the newly created mod_jk.so to your Apache2 modules directory. My modules were located at /usr/lib/apache2/modules.

[root@map007 /]# cp /usr/src/jakarta-tomcat-connectors-1.2.15-src/jk/native/apache-2.0/mod_jk.so /usr/lib/apache2/modules

# Configuring Tomcat and Apache

[root@map007 /]# vi /etc/apache2/workers.properties

workers.tomcat_home=/usr/lib/apache-tomcat workers.java_home=/usr/lib/jdk ps=/ worker.list=worker1 worker.default.port=8009 worker.default.host=localhost worker.default.type=ajp13 worker.default.lbfactor=1

# Save and close the file.
# Now you have to configure httpd.conf file and following lines.

[root@map007 /]# vi /etc/apache2/httpd.conf

LoadModule jk_module /usr/lib/apache2/modules/mod_jk.so # Where to find workers.properties JkWorkersFile /etc/apache2/workers.properties # Where to put jk logs JkLogFile /var/log/apache2/mod_jk.log # Set the jk log level [debug/error/info] JkLogLevel info # Select the log format JkLogStampFormat “[%a %b %d %H:%M:%S %Y] “

Save and close the file.

Now a final security point.

[root@map007 /]# chown -R tomcat:tomcat /usr/lib/apache-tomcat-5.5.16

# Now restart the Tomcat.

[root@map007 /]# cd /usr/local/tomcat/bin

[root@map007 bin]# ./shutdown.sh
[root@map007 bin]# ./startup.sh

And restart Apache:

[root@map007 /]# /etc/init.d/apache2 restart

You have Done all the Configurations.

Note :- Start Tomcat first: Always start Tomcat first and then start Apache.

References and paths:

Tomcat conf:

/usr/lib/apache-tomcat/conf/server.xml

Apache modules:

/usr/lib/apache2/modules

Apache conf:

/etc/apache2/workers.properties
/etc/apache2/httpd.conf

Tomcat stop and start:

cd /usr/local/apache-tomcat/bin
./shutdown.sh
./startup.sh

Apache2:

/etc/init.d/apache2 restart
/etc/init.d/apache2 stop
/etc/init.d/apache2 start
