1、创建脚本文件

touch /etc/init.d/mongodb.sh

2、添加启动脚本内容

先执行

vi /etc/init.d/mongodb.sh

将以下内容添加到mongodb.sh文件中：

#!/bin/bash
#
# MongoDB startup script
#

### BEGIN INIT INFO
# Provides:          mongodb
# Required-Start:    $remote_fs $syslog
# Required-Stop:     $remote_fs $syslog
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: MongoDB
# Description:       MongoDB Database Server
### END INIT INFO

# Path to MongoDB installation
MONGODB_HOME=/usr/local/mongodb

# MongoDB configuration file
MONGODB_CONF=/usr/local/mongodb/etc/mongod.conf

# MongoDB log file
MONGODB_LOG=/usr/local/mongodb/logs/mongodb.log

# Start MongoDB
start() {
    echo "Starting MongoDB..."
    $MONGODB_HOME/bin/mongod --config $MONGODB_CONF >> $MONGODB_LOG 2>&1 &
}

# Stop MongoDB
stop() {
    echo "Stopping MongoDB..."
    $MONGODB_HOME/bin/mongod --shutdown --config $MONGODB_CONF >> $MONGODB_LOG 2>&1
}

# Restart MongoDB
restart() {
    stop
    start
}

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

exit 0

3、设置脚本权限

chmod +x /etc/init.d/mongodb.sh

4、创建启动链接

ln -s /etc/init.d/mongodb.sh /etc/rc.d/

5、添加到开机启动服务

chkconfig --add mongodb.sh

6、设置开启自启动

chkconfig mongodb.sh on

7、启动MongoDB服务

service mongodb.sh start

8、验证重启是否启动

首先重启电脑，再执行

ps aux | grep mongod

输出如下界面

说明设置成功
