 installating tomcat,apache and integrating both

INSTALLATION STEPS

Required files

   httpd-2.2.13.tar.gz

  apache-tomcat-6.0.20.tar.gz

  jdk-6u16-linux-i586.bin

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

Installing Java and Tomcat

              JAVA

             -------

  1.              First change the permission of the downloaded file

                        

                         chmod +x jdk-6u16-linux-i586.bin

  2.              Now execute the file

                        

                         ./jdk-6u16-linux-i586.bin

  3.              It will create you a folder named "jdk1.6.0_16" in the path where you have done the prev                    step.

  4.              Move the folder to your desired path

             

                         mv jdk1.6.0_16 /usr/local/jdk1.6.0_16

  5.              Set JAVA_HOME environment variable in /etc/profile file.

                                   

                                    now we r done with java.

             TOMCAT

        -----------

   1.              First extract the downloaded tar file "apache-tomcat-6.0.20.tar.gz"

                         eg:- tar xvzf apache-tomcat-6.0.20.tar.gz

   2.              Move the extracted directory to your desired path

                         mv apache-tomcat-6.0.20 /usr/local/apache-tomcat-6.0.20

   3.              Set environment variable for tomcat(CATALINA_HOME) in /etc/profile file

   4.              Try starting tomcat by giving the following command

                        

                         /usr/local/apache-tomcat-6.0.20/bin/./startup.sh

   5.              If every thing went fine,by giving

                                    http://localhost:8080/

              you should be able to c the tomcat page.

                        

Installaing Apache

By default, if you have done a full installation of ORACLE ENTERPRISE LINUX apache will be preinstalled, Its better to remove it( yum uninstall httpd) and install a never version.

  1.      Untar the httpd-2.2.13.tar.gz file (tar xvzf httpd-2.2.13.tar.gz)

  2.     Get into the directory created during extraction (eg : cd /root/Desktop/httpd.2.2.13)

  3.     Configure apache for installation by giving

                        

               ./configure --prefix=/usr/local/apache

  4.    Next is to make the files

                        

                     make

  5.    Now install the apache server

                        

                   make install

  6.    If the installation goes correctly, folders will be created in /usr/local/apache or the               
path you gave during configuration.

  7.    Now try to start the apache server by giving

             

          /usr/local/apache/bin/apachectl start

  this will start your apache server, open your browser and check if apache is                                     
started

                        

            http://localhost

Integrating Tomcat and Apache using jk connector.

1.   Extract the downloaded “jakarta-tomcat-connectors-1.2.15-src.tar.gz” file to

eg:- jakarta-tomcat-connectors-1.2.15-src.tar.gz

2. Create the custom configure file for your system

./buildconf.sh

3. Now configure the connector with apxs(it will be available in apache’s bin folder)

./configure --with-apxs=/usr/local/apache/bin/apxs

4. Now we should build the mod_jk

make

5. If every thing worked as planned we can find the mod_jk.so in apache-2.0 directory inside the connector.

Move the created file to apache modules directory

cp /usr/src/ jakarta-tomcat-connectors-1.2.15-src/jk/native/apache-2.0/mod_jk.so  /usr/local/apache/modules

6. Create a workers file in apache home directory

touch  /usr/local/apache/workers.properties

7. Include the following line inside the properties file.

workers.tomcat_home=/usr/local/ apache-tomcat-6.0.20/

workers.java_home=/usr/local/jdk1.6.0_16

ps=/

worker.list=worker1

worker.default.port=8009

worker.default.host=localhost

worker.default.type=ajp13

worker.default.lbfactor=1

8. Now open the /usr/local/apache/conf/httpd.conf file and add the following lines.

LoadModule jk_module /usr/local/apache/modules/mod_jk.so

# Where to find workers.properties

JkWorkersFile /usr/local/apache/workers.properties

# Where to put jk logs (create dir named apache if not avail)

JkLogFile /var/log/apache/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] "

# JkOptions indicate to send SSL KEY SIZE,

JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories

# JkRequestLogFormat set the request format

JkRequestLogFormat "%w %V %T"

# Send servlet for context /yourproject to worker named worker1

JkMount /projectname worker1

# Send JSPs for context /jsp-examples/* to worker named worker1

JkMount /projectname /* worker1

9. Include the following line inside the catalina.sh  file in tomcat /lib folder

JAVA_OPTS="$JAVA_OPTS -javaagent:$CATALINA_HOME/lib/spring-agent.jar"

10. Move the follwing jar files in tomcat/lib folder

              spring-agent.jar

spring-tomcat-weaver to tomcat/lib folder

Now Start your tomcat and apache servers.

If you give http://localhost/projectname it should work fine.

workers.tomcat_home=/usr/local/apache-tomcat-6.0.20/

workers.java_home=/usr/local/jdk1.6.0_16

ps=/

worker.list=worker1,ajp13

worker.ajp13.port=8009

#worker.ajp13.host=10.100.101.195

worker.ajp13.host=dmacseaplx01.dmac.wdssvcs.com

worker.ajp13.type=ajp13

worker.ajp13.lbfactor=5
