Ubuntu 16.04启动Mongodb服务失败

Question

当我尝试使用sudo service mongod start命令启动mongodb服务时，它不起作用。仔细检查'sudo服务神神状态‘，结果如下：

● 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

  Process: 21352 ExecStart=/usr/bin/mongod --config /etc/mongod.conf (code=exited, status=1/FAIL

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用户可以使用以下命令访问\tank\mongo目录：sudo chown -R mongodb:users /tank/mongo。

事实证明，我应该将权限授予mongodb:mongodb，不仅如此；子文件夹没有继承权限，因此我必须在配置/tank/mongo/log/mongodb/、/tank/mongo/mongodb中指定的文件夹级别授予权限。

我留下了答案，以防它可能会帮助处于类似情况的人。
