### 4、Mongodb 啟動和停止服務 Mongodb 啟動： 1、mongod --fork --port 12345 --dbpath /srv/mongodb/ 2、mongod -f /data/mongodb/conf/mongodb.conf 推薦第二種方式把配置寫進文件啟動。 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）終止mongod實例。 前兩種方式就不介紹了： 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() 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:25:13 DB.prototype.shutdownServer@src/mongo/shell/db.js:426:19 @(shell):1:1 rs02:SECONDARY> ``` 需要使用localhost連接mongo實例，在配置文件啟動時候添加： >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() 2020-03-20T14:47:49.186+0800 I NETWORK [js] DBClientConnection failed to receive message from localhost:27020 - HostUnreachable: Connection closed by peer server should be down... ``` 官網詳細介紹地址：https://docs.mongodb.com/manual/tutorial/manage-mongodb-processes/
