mongodb 自动启动

在etc/init.d目录下建立文件mongodb

#!/bin/sh  
#chkconfig: 2345 93 18  
#description:auto_run

#MogoDB home directory  
MONGODB_HOME=/usr/local/mongodb

#mongodb command  
MONGODB_BIN=$MONGODB_HOME/bin/mongod

#mongodb config file
MONGODB_CONF=$MONGODB_HOME/conf/start.conf

#mongodb PID
MONGODB_PID=/mongodbdata/mongo.pid

#set open file limit
SYSTEM_MAXFD=65535

MONGODB_NAME="mongodb"
. /etc/rc.d/init.d/functions

if [ ! -f $MONGODB_BIN ]
then
        echo "$MONGODB_NAME startup: $MONGODB_BIN not exists! "  
        exit
fi

start(){
     ulimit -HSn $SYSTEM_MAXFD
     su - mongouser -c "$MONGODB_BIN --config="$MONGODB_CONF"  --fork" ##added @20160901
     ret=$?

     if [ $ret -eq 0 ]; then
        action $"Starting $MONGODB_NAME: " /bin/true
     else
        action $"Starting $MONGODB_NAME: " /bin/false
     fi
}

stop(){
        PID=$(ps aux |grep "$MONGODB_NAME" |grep "$MONGODB_CONF" |grep -v grep |wc -l) 
        if [[ $PID -eq 0  ]];then
        action $"Stopping $MONGODB_NAME: " /bin/false
        exit
        fi

        kill -HUP `cat $MONGODB_PID`
        ret=$?
        if [ $ret -eq 0 ]; then
                action $"Stopping $MONGODB_NAME: " /bin/true
                rm -f $MONGODB_PID
        else   
                action $"Stopping $MONGODB_NAME: " /bin/false
        fi
}



restart() {
        stop
        sleep 2
        start
}



case "$1" in
        start)
                start
                ;;
        stop)
                stop
                ;;
        status)
        status $prog
                ;;
        restart)
                restart
                ;;
        *)
                echo $"Usage: $0 {start|stop|status|restart}"
esac

完成后 使用 chkconfig mongodb on 设置为生效

然后开机自动启动 su - mongouser 说明使用了mongouser 来启动服务
