How do I setup MongoDB so that it will start back up automatically after a server reboot? This is on CentOS 5.5.
I start it with the following command, but if the server reboots, I have to login to SSH and run that again to get it going (not that big of a deal really, but would be nice to know that this isn't necessary if I don't have access to the server).
./mongod --config ./mongodb.config --fork --logpath /var/log/mongodb.log --logappend
Your best bet is to install the rpms provided by 10gen (makers of mongodb)
http://www.mongodb.org/display/DOCS/CentOS+and+Fedora+Packages
That will install a init.d script for you that you can run
//mongod service
You need to write an "init script" to start the service when the system boots. A quick Google search for "writing init scripts redhat" will turn up several useful references. This seemed like a reasonable start:
If you want a quick-and-dirty solution, you can simply add your command to the end of
/etc/rc.d/rc.local
, which gets executed after all the other init scripts have completed.
