mongodb启动关闭脚本

每次重启mongodb是真的麻烦，今天有时间就写个自启脚本：

# vim  mongod_up.sh

#!/bin/bash

mongod=/home/mongodb/bin/mongod                      #mongodb启动命令

mongod_conf=/home/mongodb/conf/mongodb.conf          #mongodb主配置文件路径，里面包含了logs存放路径及data路径等

mongpid=/var/run/mongodb                             #mongodb的pid文件存放路径

prog=mongod_up.sh                                     #脚本名

RETVAL=0
 
stop() {
    grep_mongo=`ps aux | grep -v grep | grep "mongod"`
    if [ ${#grep_mongo} -gt 0 ]
    then
    echo "Stop MongoDB."
    PID=`ps x | grep -v grep | grep "mongod"  | awk '{ print $1 }'`
    `kill -2 ${PID}`
    RETVAL=$?
    else
    echo "MongoDB is not running."
    fi
}
start() {
    grep_mongo=`ps aux | grep -v grep | grep "mongod"`
    if [ -n "${grep_mongo}" ]
    then
    echo "MongoDB is already running."
    else
    echo "Start MongoDB."
      if [ ! -d ${mongpid} ]; then           #这里需要判定pid文件是否丢失，不知道什么原因pid文件，会因为mongodb错误退出导致无法启动
      mkdir -p ${mongpid}
      ${mongod} --config ${mongod_conf}
      else
      ${mongod} --config ${mongod_conf}
      fi
    RETVAL=$?
    fi
}
 
case "$1" in
    start)
    start
    ;;
    stop)
    stop
    ;;
    restart)
    stop
    start
    ;;
    *)
    echo $"Usage: $prog {start|stop|restart}"
    exit 1
esac
 
exit $RETVAL
