Note that the first time the HQ server starts up it may take several minutes
to initialize. Subsequent startups will be much faster.
Once the HQ server reports that it has successfully started, you can log in
to your HQ server at:
http://X.X.X.X:7080/
username: hqadmin
password: asdsdsdff
To change your password, log in to the HQ server, click the “Administration”
link, choose “List Users”, then click on the “hqadmin” user.

Step by step install and configure Apache+Tomcat+mod_jk+load Balancing+Clustering

  • Apache 2.2.x
  • Tomcat 6.0.X OR Above
  • Jdk1.5 or above
  • Mod_jk.1.2.26.so
Installing apache :
# yum install httpd*
Then extract jdk on /usr/local directory
#cd /usr/local
#./jdk-6u23-linux-i586.bin
Than make it three copy of jdk
[root@localhost local]# cp -r jdk1.6.0_23 jdk1.6.0_23-1
[root@localhost local]# cp -r jdk1.6.0_23 jdk1.6.0_23-2
[root@localhost local]# cp -r jdk1.6.0_23 jdk1.6.0_23-3
Also extrat the tomcat file.
[root@localhost local]#tar –xvzf apache-tomcat-6.0.18.tar.gz
[root@localhost local]# mv apache-tomcat-6.0.18 tomcat-1
[root@localhost local]# cp tomcat-1 tomcat-2
cp: omitting directory `tomcat-1′
[root@localhost local]# cp -r tomcat-1 tomcat-2
[root@localhost local]# cp -r tomcat-1 tomcat-3
Map jdk with tomcat
[root@localhost local]#cd tomcat-1/bin
Open catalina.sh file and make it JAVA_HOME
[root@localhost bin]#vi catalina.sh
# OS specific support. $var _must_ be set to either true or false. (below this line )
JAVA_HOME=/usr/local/jdk1.6.0_23-1

Intigrate apache +tomcat with mod_jk+load Balanceing
Download supportable file for apache server (It’s depend on http version).
  • Downlaod and rename this mod_jk.1.2.24.so to mod_jk.so then past in /etc/httpd/modules/
  • Then open httpd.conf file and make this entry: LoadModule jk_module modules/mod_jk.so , be sure mod_jk.so working or not with restart httpd service.
[root@localhost apache_tomcat]# ls
catalina.sh httpd.conf mod_jk.so server.xml web.xml worker.properties
[root@localhost apache_tomcat]# cp mod_jk.so /etc/httpd/modules/
[root@localhost apache_tomcat]# service httpd restart
Stopping httpd: FAILED]
Starting httpd: OK ]
Note: ( if httpd not starting means your mod_jk.so is not correct file , download sutable file then check again.)
  • Create in /ets/httpd/conf/worker.properties file and make this entry
For Single
worker.list = worker1
