1、编辑mongodb.service文件
将MongoDB设置成系统服务，就可以通过systemctl进行启动停止重启，在目录/etc/systemd/system下编写mongodb.service文件：
|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Unit Description=MongoDB Database Server Documentation=https://www.mongodb.com/docs/ After=network.target Service ExecStart=/usr/local/mongodb/bin/mongod --config /usr/local/mongodb/mongod.conf ExecReload=/bin/kill -s HUP $MAINPID ExecStop=/usr/local/mongodb/bin/mongod --shutdown --config /usr/local/mongodb/mongod.conf Restart=always LimitNOFILE=64000 LimitNPROC=64000 Install WantedBy=multi-user.target |
2、重新加载systemd服务配置
|------------------------------|
| sudo systemctl daemon-reload |
3、设置开机自启动
|-------------------------------|
| sudo systemctl enable mongodb |
4、MongoDB常用命令
|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 启动MongoDB服务：sudo systemctl start mongodb 停止MongoDB服务：sudo systemctl stop mongodb 重启MongoDB服务：sudo systemctl restart mongodb 查看MongoDB服务状态：sudo systemctl status mongodb |
