MongoDB

This chapter will explain how to setup mongod service on CentOS 6.5 : # service mongod start | stop | restart

 

1. If old rc.d script exists remove it with: #chkconfig --del mongod

2. #cd /etc/rc.d/init.d/

3. Rename or remove old script: # mv mongod mongod_bak

4. Create new script: # vim mongod

#!/bin/sh
#
# Note runlevel 2345, 86 is the Start order and 85 is the Stop order
#
# chkconfig: 2345 86 85
# description: Description of the Service
#
#Source function library
. /etc/init.d/functions


start(){  
        mongod --config /etc/mongod.conf
}

stop(){  
        mongod --shutdown --config /etc/mongod.conf
}

restart(){  
        mongod --shutdown --config /etc/mongod.conf
        mongod --config /etc/mongod.conf
}

case "$1" in  
        start)
                echo "Start service mongod"
                start
                ;;
        stop)
                echo "Stop service mongod"
                stop
                ;;
        restart)
                echo "Restart service mongod"
                restart
                ;;
        *)
                echo "Usage: $0 {start|stop|restart}"
                exit 1
                ;;
esac

 

5. Set exe permissions to file: # chmod a+x  mongod

6. Add service: # chkonfig --add mongod

7. Check if everything is ok:

# chkconfig | grep mongod

mongod          0:off   1:off   2:on    3:on    4:on    5:on    6:off

 

8. Now you can use commands: # service mongod start | stop | restart . Also, MongoDB will be started automatically on reboot.
