Mongodb 服务无法在 Ubuntu 16.04 上启动

Question

当我尝试使用命令 sudo service mongod start 启动 mongodb 服务时，它不起作用。在使用“sudo service mongod status”仔细检查后，发现以下内容:

● mongod.service - High-performance, schema-free document-oriented database
   Loaded: loaded (/lib/systemd/system/mongod.service; disabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Mon 2017-09-18 21:00:29 CEST; 7s ago
     Docs: https://docs.mongodb.org/manual
  Process: 21352 ExecStart=/usr/bin/mongod --config /etc/mongod.conf (code=exited, status=1/FAIL
 Main PID: 21352 (code=exited, status=1/FAILURE)

Sep 18 21:00:29 zeus systemd[1]: Started High-performance, schema-free document-oriented databas

Sep 18 21:00:29 zeus systemd[1]: mongod.service: Failed with result 'exit-code'.

配置文件已更改为以下内容:

# Where and how to store data.
storage:
  dbPath: /tank/mongo/mongodb
  journal:
    enabled: true

# where to write logging data.
systemLog:
  destination: file
  logAppend: true
  path: /tank/mongo/log/mongodb/mongod.log

# network interfaces
net:
  port: 27017
  bindIp: 127.0.0.1

mongodb 用户被授予访问 \tank\mongo 的权限目录使用命令:sudo chown -R mongodb:users /tank/mongo .

Answer 1

原来我应该允许 mongodb:mongodb ，不仅如此；子文件夹没有继承权限，所以我必须在配置中指定的文件夹级别授予权限 /tank/mongo/log/mongodb/ , /tank/mongo/mongodb .

我留下答案，以防它可能对处于类似情况的人有所帮助。
