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
启动Mongod作为服务：
sudo service mongod start
（一旦我开始工作，我想让mongod在服务器通过chkconfig重新启动时启动：
sudo /sbin/chkconfig --level 345 mongod on
）
会发生什么
它返回[失败]，我在日志中收到此消息：

我试过的：
重映射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酒店
更改数据库的所有者没有帮助：
sudo chown-r我的用户名/var/lib/mongo
最佳答案
这看起来像是权限问题：

假设您已经删除了.lock文件，那么看看mongo正在运行的用户是否有权对该文件夹进行写操作。
你在用户名上使用chown，但似乎用户必须是mongo，而不是你的用户名。当服务尝试启动时，请检查所有者。
关于linux - 无法将Mongo作为服务运行，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/25518506/
