我在尝试启动 mongodb 时遇到问题，下面我将向您显示错误：

    xxx@xxx [/var/lib/mongo]# /etc/init.d/mongod start
    Starting mongod: all output going to: /var/log/mongo/mongod.log
                                                           [FAILED]

在 mongod.log 上看到我收到以下通知：

***** SERVER RESTARTED *****

引起我注意的是：

/var/lib/mongo 里面的文件夹和文件有 0755 权限。

如果有人能告诉我这样做的方法，我将不胜感激。

我解决了错误，这是因为我只将mongod用户分配给/var/lib/mongo而不是其中的文件，以下命令解决了这部分：chown -R mongod:mongod /var/lib/mongo.

然后只需要用用户mongod使用以下命令修复数据库：sudo -u mongod mongod -f /etc/mongod.conf --repair，我终于成功启动了数据库。

我希望这对其他人有帮助。

谢谢大家的答案。

也许上次mongod进程被错误终止时，尝试删除mongo.lock它应该会有所帮助

我假设您正在以 root身份运行service mongodb start/stop/restart/status命令？.. 使用 sudo 吗？如果我尝试以普通用户身份启动它，我会收到该错误。
