linux - 无法将 Mongo 作为服务运行

Question

我的环境

• CentOS(我不确定确切的版本，因为它在 iPage 的 VPS 服务器上。)

我的目标

将 mongod 作为服务启动:

sudo service mongod start

(一旦我开始工作，我想让 mongod 在服务器重新启动时通过 chkconfig 启动:

sudo /sbin/chkconfig --level 345 mongod on

)

发生了什么

它返回 [FAILED]，我在日志中收到此消息:

我尝试过的:

• 搜索当前进程未找到任何 mongod 进程:

  ps 辅助 | grep mongod

• 删除 mongod.lock 文件没有帮助:

  sudo rm mongod.lock

• 更改数据库的所有者没有帮助:

  sudo chown -R my_username/var/lib/mongo

Answer 1

这看起来像是权限问题:

假设您已经删除了 .lock 文件，请查看运行 mongo 的用户是否有权写入该文件夹。

您正在使用 chown 和您的用户名，但似乎用户必须是 mongo，而不是您的用户名。当服务尝试启动时检查所有者。
