MongoDB 存储问题（9001 已在使用）

Question

我在尝试运行命令时收到此错误 mongod --dbpath=/var/lib/mongodb

{"t":{"$date":"2021-01-23T11:23:41.733-07:00"},"s":"I",  "c":"CONTROL",  "id":51765,   "ctx":"initandlisten","msg":"Operating System","attr":{"os":{"name":"Ubuntu","version":"20.04"}}}
{"t":{"$date":"2021-01-23T11:23:41.733-07:00"},"s":"I",  "c":"CONTROL",  "id":21951,   "ctx":"initandlisten","msg":"Options set by command line","attr":{"options":{"storage":{"dbPath":"/var/lib/mongodb"}}}}
{"t":{"$date":"2021-01-23T11:23:41.734-07:00"},"s":"E",  "c":"STORAGE",  "id":20568,   "ctx":"initandlisten","msg":"Error setting up listener","attr":{"error":{"code":9001,"codeName":"SocketException","errmsg":"Address already in use"}}}

我确实看到问题是 "attr":{"error":{"code":9001,"codeName":"SocketException","errmsg":"Address already in use"}}}

但我不知道如何解决这个问题？

我尝试了另一篇 SO 帖子中的其他建议，该建议说要终止进程并重新启动。我这样做了，但它对我不起作用。

我还尝试在不同的端口上运行 mongod

mongod --dbpath=/var/lib/mongodb --port 27019

这给了我这个错误

{"t":{"$date":"2021-01-23T11:27:29.535-07:00"},"s":"E",  "c":"STORAGE",  "id":20557,   "ctx":"initandlisten","msg":"DBException in initAndListen, terminating","attr":{"error":"IllegalOperation: Attempted to create a lock file on a read-only directory: /var/lib/mongodb"}}

所以它是一个只读目录所以我跑了

sudo chmod -R 777 /var/lib/mongodb

然后我在日志中收到此错误

"ctx":"initandlisten","msg":"DBException in initAndListen, terminating","attr":{"error":"DBPathInUse: Unable to lock the lock file: /var/lib/mongodb/mongod.lock (Resource temporarily unavailable). Another mongod instance is already running on the /var/lib/mongodb directory"}}

所以我尝试找出正在运行的其他进程

ps -eaf | grep mongod

mongodb   722732       1  0 11:09 ?        00:00:10 /usr/bin/mongod --config /etc/mongod.conf
srt       725772  720106  0 11:34 pts/2    00:00:00 grep --color=auto --exclude-dir=.bzr --exclude-dir=CVS --exclude-dir=.git --exclude-dir=.hg --exclude-dir=.svn --exclude-dir=.idea --exclude-dir=.tox mongod

但我不知道从这里该做什么。

Answer 1

您已经使用默认的 /etc/mongod.conf 文件运行默认自动启动的 mongod 实例，您可以通过以下方式停止该实例：

  service mongod stop

或者

  kill -2 722732

或者

 mongo --port 27017
 >use admin
 >db.shutdownServer()

或者

 systemctl stop mongod

您可以根据需要修改 /etc/mongod.conf 文件并再次启动

  service mongod start

或者：

 systemctl start mongod
