I have worked on this for our application to start up when ever there is a power on. On the VMware esxi host we can add a virtual machine to power on automatically when host restarts.
After starting the virtual machine the tomcat service in the server was not starting in our case. So, I followed VMware documentations and listed the important commands to do the same task here.
The following are the steps to make the tomcat or web services to start automatically when a virtual machine starts.
We need to create a tomcat user with sudo permissions
adduser tcserver sudo
Make him owner for all files and sub directories of CATALINA_HOME
Edit
CATALINA_HOME/bin/init.d.sh
Modiy
TC_RUNTIME_USER="tc-server" to TC_RUNTIME_USER="tcserver"
Link the init.d.sh to /etc/init.d/{servicename}
ln -s /var/opt/vmware/vfabric-tc-server-standard/tcserver/bin/init.d.sh \ /etc/init.d/tcserver
After that we can test the service is working or not just by
To start the server instance
/etc/init.d/tcserver start
To get status the server instance
/etc/init.d/tcserver status
To restart the server instance
/etc/init.d/tcserver restart
To staop the server instance
/etc/init.d/tcserver stop
This is important after above to start the instance on boot we need to update the rc.d add the service instance to defaults
update-rc.d webserver defaults
For webservers I just made the link and updated the rc.d and it just works fine.
# ln -s /var/opt/vmware/vfabric-web-server/webserver/bin/httpdcl /etc/init.d/webserver
# update-rc.d webserver defaults
