The system is centos 6.4 64-bit
MASTER: 192.168.1.61
Backup: 192.168.1.62
Floating IP Address: 192.168.1.64

1. JBoss installation Configuration:
Yum install Java-1.7.0 *-y
Unzip jboss-5.1.0.GA.zip-D/usr/local
Ln-SV jboss-5.1.0.GA JBoss
CD/usr/local/JBoss/Server
CP-r default default_init
CP-r default jboss-gh1 (project directory)
Put the project package under the jboss-gh1 directory
Modify the configuration file so that it can access the Domain Name
[[Email protected] WEB-INF] # pwd
/Usr/local/JBoss/Server/JBoss-ghl/deploy/ghn. War/WEB-INF
[[Email protected] WEB-INF] # Cat jboss-web.xml

Suffix = ". log"

Directory = "$ {JBoss. server. log. dir }"

</Host>
</Engine>
</Service>
</Server>
Then write the startup script.
In order to facilitate the test, I wrote a test page

The JBoss configuration is complete.
Second, configure haproxy and keepalive
Both haproxy and keepalived are directly installed in yum.
Haproxy configuration (master and slave are the same)
