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 --shutdownkilling process with pid: 28761

4、db.shutdownServer()

[root@10-1-1-159 ~]# sudo -u mongod /data/mongodb-4.2.2/bin/mongo 10.1.1.159:27010rs02:SECONDARY> db.getMongo().setSlaveOk()rs02:SECONDARY> use adminswitched to db adminrs02:SECONDARY> db.shutdownServer()2020-03-20T14:37:28.602+0800 E QUERY [js] Error: shutdownServer failed: { "operationTime" : Timestamp(1584686240, 1), "ok" : 0, "errmsg" : "shutdown must run from localhost when running db without auth", "code" : 13, "codeName" : "Unauthorized", "$clusterTime" : { "clusterTime" : Timestamp(1584686240, 1), "signature" : { "hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="), "keyId" : NumberLong(0) } }} :_getErrorWithCode@src/mongo/shell/utils.js:25:13DB.prototype.shutdownServer@src/mongo/shell/db.js:426:19@(shell):1:1rs02:SECONDARY>

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:27020use adminswitched to db admindb.shutdownServer()2020-03-20T14:47:49.186+0800 I NETWORK [js] DBClientConnection failed to receive message from localhost:27020 - HostUnreachable: Connection closed by peerserver should be down...
