Install RHQ agent on linux

Installing RHQ agent is simple. Only thing you have to do is just download plugin jar save it and run the installation command like java -jar <agent-download.jar> --install=<agent directory>. But i want to explain how we can install the agent as a service.

With the following script rhq enterprise agent 4.2.0 can be installed as a service on redhat linux.
#!/bin/bash
script_dir=$PWD
jb_home=~jboss
echo $jb_home
export JAVA_HOME=<your jvm>
echo <your server ip>       <your server name>  >> /etc/hosts
cp -fr rhqagent-init-script /etc/init.d/rhqagent
chmod 755 /etc/init.d/rhqagent


mkdir $jb_home/rhqagent
chown -R jboss:jboss $jb_home/rhqagent
chmod 755 $jb_home/rhqagent
java -jar rhq-enterprise-agent-4.2.0.jar --install=$jb_home/rhqagent
$jb_home/rhqagent/rhq-agent/bin/rhq-agent.sh


Remember: RHQ agent will be installed to the jboss user's home path. So if you want to use different path change the path accordingly. And also you can change the jvm path to yours. Service name is rhqagent

  1. Question on this Line :
    cp -fr rhqagent-init-script /etc/init.d/rhqagent

    As i understood, your script above (the whole) is named rhqagent-init-script.
    but with this line, your script is copied to init.d But then it always runs through the whole setup again ? or what is meant by "rhqagent-init-script" ?

  2. hmm. When i first install rhqagent manually with " java -jar --install=" command, rhq-init-script came from there. so the above script (let's call it rhq-agent-install.sh) is different from rhq-init-script which contains:
    #!/bin/sh
    # description:rhqagent
    # chkconfig: 345 80 20

    export JAVA_HOME=/usr/java/default

    function main {
    case "$1" in
    start)
    ~jboss/rhqagent/rhq-agent/bin/rhq-agent-wrapper.sh start
    ;;
    stop)
    ~jboss/rhqagent/rhq-agent/bin/rhq-agent-wrapper.sh stop
    ;;
    kill)
    ~jboss/rhqagent/rhq-agent/bin/rhq-agent-wrapper.sh kill
    ;;
    restart)
    ~jboss/rhqagent/rhq-agent/bin/rhq-agent-wrapper.sh restart
    ;;
    status)
    ~jboss/rhqagent/rhq-agent/bin/rhq-agent-wrapper.sh status
    ;;
    *)
    echo "Usage: $0 { start | stop | kill | restart | status }"
    exit 1
    ;;
    esac
    }
    main $1

    I forgot putting it to the post. Sorry :)
    Last but not least, these three files(init script, install.sh and jar file) should be in same folder. Good luck.
