install and confiugre glassfish version 3.1.2 and serve it via apache 2.4 server in front of glass fish ones using mod_jk

apache_jk_glassfish.md

• glassfish_server:

  • hostname: gf.localdomain
  • ip: 192.168.1.200

• apache_server:

  • hostname: web.localdomain
  • ip: 192.168.1.100

• @glassfish_server: 0. packages that needs to be installed: yum -y install wget unzip epel-release vim

  1. make sure that epel repo is installed: yum -y install epel-release
  2. install openjdk-6: yum -y install java-1.6.0-openjdk java-1.6.0-openjdk-devel
  3. download glassfish 3.1.2: cd /opt && wget http://download.java.net/glassfish/3.1.2/release/glassfish-3.1.2.zip
  4. make sure that unzip command is installed: yum -y install unzip
  5. extract glassfish zip file at /opt dir: cd /opt && unzip glassfish-3.1.2.zip
  6. start glassfish domain: /opt/glassfish3/glassfish/bin/asadmin start-domain
  7. create an HTTP listeren on port 8009 and enable jk on it requires 2 commands:
  • /opt/glassfish3/glassfish/bin/asadmin create-http-listener --listenerport 8009 --listeneraddress 192.168.1.200 --defaultvs server jk-connector
    • note: 192.168.1.200 is my glassfish server public ip
  • /opt/glassfish3/glassfish/bin/asadmin set configs.config.server-config.net work-config.network-listeners.network-listener.jk-connector.jk-enabled=true
  8. restart glassfish domain: /opt/glassfish3/glassfish/bin/asadmin restart-domain
  9. use netstat command and make sure that java is listening on public ip and port 8009 like the picture: http://i.imgur.com/6CAuGJd.jpg
  10. now we jump to web server and apache, mod_jk configurations

---

• @apache_server: 0. packages that needs to be installed: yum -y install wget unzip epel-release vim telnet gcc
  1. install telnet and make sure that web server is able to talk to port 8009 on GF server:
  • yum -y install telnet
  • telnet 192.168.1.200 8009
    • you should see a picture like this: http://i.imgur.com/15OFplr.jpg
  2. make sure that epel repo is installed: yum -y install epel-release
  3. install apache 2.4 repo: cd /etc/yum.repos.d/ && wget http://repos.fedorapeople.org/repos/jkaluza/httpd24/epel-httpd24.repo
  4. install apache 2.4 and apache 2.4 devel packages: yum install httpd24 httpd24-httpd-devel
  5. source the enable file to let the system recognize httpd24 binaries: source /opt/rh/httpd24/enable
  6. download mod_jk: cd /usr/local/src && wget http://mirror.tcpdiag.net/apache/tomcat/tomcat-connectors/jk/tomcat-connectors-1.2.40-src.tar.gz
  7. extract downloaded mod_jk file: tar xvf tomcat-connectors-*
  8. remove source file: rm -f /usr/local/src/tomcat-connectors*.tar.gz
  9. install mod_jk: cd /usr/local/src/tomcat*/native && ./configure --with-apxs=/opt/rh/httpd24/root/usr/bin/apxs && make && make install
  10. create a module config file /opt/rh/httpd24/root/etc/httpd/conf.modules.d/00-modjk.conf then open it and paste the following content and save

  LoadModule jk_module /opt/rh/httpd24/root/usr/lib64/httpd/modules/mod_jk.so
  JkWorkersFile /opt/rh/httpd24/root/etc/httpd/conf/workers.properties
  JkLogFile     /opt/rh/httpd24/root/var/log/httpd/mod_jk_log
  JkLogLevel    info
  

  11. create a worker.properties file /opt/rh/httpd24/root/etc/httpd/conf/workers.properties then open it and paste the following content and save

  worker.list=worker1
  worker.worker1.type=ajp13
  worker.worker1.port=8009
  worker.worker1.host=gf.localdomain
  worker.worker1.lbfactor=1
  

  • note: worker.worker1.host should equal the GF server ip or hostname gf.localdomain in our case.
  12. add virtualhost file /opt/rh/httpd24/root/etc/httpd/conf.d/gf.conf for glassfish and paste the following content into it and save

  <VirtualHost *:80>
  ServerName web.localdomain
  JkMount /* worker1
  </VirtualHost>
  

  13. start apache web server: /opt/rh/httpd24/root/usr/sbin/apachectl -k start
  14. make sure that your /etc/hosts file is able to resolve web.localdomain and the try with your browser and you should see this result: http://i.imgur.com/hejQTsh.jpg
