注册mongodb服务

cd /etc/init.d/
vim mongodb

添加如下代码

#!/bin/sh  
#  
#  ### BEGIN INIT INFO 
# Short-Description: mongodb  
# chkconfig:   - 85 15
# Description: mongo db server    
### END INIT INFO    


PROGRAM=/usr/local/mongodb/bin/mongod
MONGOPID=`ps -ef | grep 'mongod' | grep -v grep | awk '{print $2}'`
##prog=$(basename /usr/local/mongodb/bin/mongod)
##检测文件是否具有可执行权限
test -x $PROGRAM || exit 0

start(){
    ulimit -n 3000
    echo "Starting MongoDB server"
    $PROGRAM --fork --quiet -f /usr/local/mongodb/bin/mongod.conf
    echo "Started MongoDB server"
}
stop(){
    echo "Stopping MongoDB server"
    if [ ! -z "$MONGOPID" ]; then
       kill -9 $MONGOPID
    fi
    echo "Stopped MongoDB server"
}
case "$1" in
  start)
     $1
     ;;
  stop)
     $1
     ;;
  restart)
     $1
     ;;
  status)
     ps -ef | grep 'mongod' | grep -v grep | awk '{print $2}'  > /tmp/mongodb_process_count.txt
    read line < /tmp/mongodb_process_count.txt
    if [ $line -gt 0 ]; then
       echo "MongoDB is running,pid is "$line
    else
       echo "MongoDB is stoped"
    fi
     ;;
  *)
     echo "Usage: mongodb {start|stop|status}"
     exit 1
esac

exit 0

添加可执行权限

chmod +x mongodb
