Mongodb服务启动和停止

Posted 2021-02-27

4、Mongodb 启动和停止服务

Mongodb 启动：

1、mongod --fork --port 12345 --dbpath /srv/mongodb/
2、mongod -f /data/mongodb/conf/mongodb.conf
推荐第二种方式把配置写进文件启动。

Mongodb停止：

1、kill -2 (mongod process ID)
2、kill (mongod process ID)
3、mongod --shutdown
4、db.shutdownServer()
切勿使用kill -9（即SIGKILL）终止mongod实例。

前两种方式就不介绍了：
3、 --shutdown

[root@10-1-1-159 ~]# sudo -u mongod /data/mongodb-4.2.2/bin/mongod  -f /data/mongodb/conf/mongodb.conf --shutdown
killing process with pid: 28761

4、db.shutdownServer()

[root@10-1-1-159 ~]#  sudo -u mongod /data/mongodb-4.2.2/bin/mongo 10.1.1.159:27010
rs02:SECONDARY> db.getMongo().setSlaveOk()
rs02:SECONDARY> use admin
switched to db admin
rs02:SECONDARY> db.shutdownServer()

需要使用localhost连接mongo实例，在配置文件启动时候添加：

bindIp: 10.1.1.159,localhost

[root@10-1-1-159 ~]# sudo -u mongod /data/mongodb-4.2.2/bin/mongo localhost:27020
use admin
switched to db admin
db.shutdownServer()
