Hi,
When tries to start / stop Jira with command service jira start / service jira stop I am getting the below error
To run JIRA in the foreground, start the server with start-jira.sh -fg
executing using dedicated user: jira2
./startup.sh: line 62: /opt/atlassian/jira/bin/catalina.sh: Permission denied
./startup.sh: line 62: exec: /opt/atlassian/jira/bin/catalina.sh: cannot execute: Permission denied
When start Jira with the command sh /opt/atlassian/jira/bin/startup.sh Jira is starting and working fine.
I tried chmod 777 for the installation and home directory of Jira and still nothing happends. 
I have unistalled and re-installed jira nore than once and i suspect this might be reason but i dont know how to resolve it.
Plese Help.. Thanks in Advance..
