    I have installed ambari-server on centOS 6.4 virtual machine.
    When I use the command “ambari-server start” ,I get the following result.my first question is that,what does it mean?

    [root@CentOS-DM-VM ~]# ambari-server start
    Using python /usr/bin/python2.6
    Starting ambari-server
    Checking iptables…
    iptables is disabled now
    Running server: /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java/bin/java -server -XX:NewRatio=3 -XX:+UseConcMarkSweepGC -XX:-UseGCOverheadLimit -XX:CMSInitiatingOccupancyFraction=60 -Xms512m -Xmx2048m -cp /etc/ambari-server/conf:/usr/lib/ambari-server/*:/usr/local/sbin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/lib/ambari-server/* org.apache.ambari.server.controller.AmbariServer >/var/log/ambari-server/ambari-server.out 2>&1

    There is a command that they say it is used for checking which ambari processes are running.the command is: “ps ef | grep Ambari”

    but I get the following result!.what does it mean? besides,I use the “jps” command to check the running java processes and I get only “3075 jps”.is ambari stopped?!

    [root@CentOS-DM-VM ~]# ps ef | grep Ambari

    Hi Dave!
    Thanks for your guidance.
    The problem was solved ;-)

    for the sake of sharing experience I explain it:

    I checked the log file and it was said that: Java Home Path /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java/bin/java is not a directory!
    So I checked the Ambari properties file (/etc/ambari-server/conf/ambari.properties) and I modified “java.home” value to this: /usr/lib/jvm/jre-1.7.0-openjdk.x86_64
    (it seems that it adds “/bin/java” to the JAVA_HOME path automatically)
    and then I ran the command: “ambari-server start” again.I got the same output result(that I mentioned in the question).but when I checked the server status by command “ambari-server status”,this time,it said that the server is running.And I can enter the web GUI now!
    the problem was solved ;-)

    thanks for your assistance again ;-)

    Hi Hesam,

    What do the Ambari logs show? (/var/log/ambari-server)

    ps -ef | grep Ambari should show a java process running Ambari, as should the jps

    If you do a netstat -an | grep 8080 is the machine listening on that port? If you go to :8080 does ambari show a web UI?

    Thanks

    Dave
