我能够通过在文件夹上设置错误的所有权来重现您的问题/var/log/mongodb：

\n\n

root@demo:~# ls -lh /var/log/mongodb/\ntotal 512\n-rw-r--r-- 1 root root 0 Jan 22 17:57 mongod.log\nroot@demo:~# systemctl restart mongod\nroot@demo:~# systemctl status mongod\n\xe2\x97\x8f mongod.service - MongoDB Database Server\n   Loaded: loaded (/lib/systemd/system/mongod.service; disabled; vendor preset: enabled)\n   Active: failed (Result: exit-code) since Tue 2019-01-22 17:57:13 UTC; 2s ago\n     Docs: https://docs.mongodb.org/manual\n  Process: 795 ExecStart=/usr/bin/mongod --config /etc/mongod.conf (code=exited, status=1/FAILURE)\n Main PID: 795 (code=exited, status=1/FAILURE)\n\nJan 22 17:57:13 demo systemd[1]: Started MongoDB Database Server.\nJan 22 17:57:13 demo systemd[1]: mongod.service: Main process exited, code=exited, status=1/FAILURE\nJan 22 17:57:13 demo systemd[1]: mongod.service: Unit entered failed state.\nJan 22 17:57:13 demo systemd[1]: mongod.service: Failed with result 'exit-code'.\n

尝试更正 MongoDB 日志记录和数据目录的所有权：

\n\n

root@demo:~# chown -Rc mongodb. /var/log/mongodb\nchanged ownership of '/var/log/mongodb/mongod.log' from root:root to mongodb:nogroup\nchanged ownership of '/var/log/mongodb' from root:root to mongodb:nogroup\nroot@demo:~# chown -Rc mongodb. /var/lib/mongodb\nroot@demo:~# systemctl restart mongod\nroot@demo:~# systemctl status mongod\n\xe2\x97\x8f mongod.service - MongoDB Database Server\n   Loaded: loaded (/lib/systemd/system/mongod.service; disabled; vendor preset: enabled)\n   Active: active (running) since Tue 2019-01-22 17:58:30 UTC; 1s ago\n     Docs: https://docs.mongodb.org/manual\n Main PID: 802 (mongod)\n   CGroup: /system.slice/mongod.service\n           \xe2\x94\x94\xe2\x94\x80802 /usr/bin/mongod --config /etc/mongod.conf\n\nJan 22 17:58:30 demo systemd[1]: Started MongoDB Database Server.\n

\n\n

如果这不起作用，请尝试重新安装 MongoDB，删除所有现有数据：

\n\n

sudo apt purge mongodb-org mongodb-org-mongos mongodb-org-server mongodb-org-shell mongodb-org-tools\nsudo rm -rfv /etc/mongod.conf /var/log/mongodb /var/lib/mongodb\nsudo find /tmp -type s -iname '*mongodb*' -delete\nsudo apt install mongodb-org\n
