我试图从mongodb.org存储库在CentOS 7.2上安装MongoDB。 到目前为止，这个主机已经为所有的MongoDB数据文件创build了一个辅助磁盘（/ mongo）。 这与SELinux权限冲突，使MongoDB无法启动。 我已经开始运行setenforce 0 ，但是这不是我想运行生产服务器的方式。
我有很多Linux的经验，但是我所有的SELinux经验都是closures的。 我发现这个CentOS SELinux教程 ，让我觉得运行

会解决这个问题。 之后，我做了一个touch /.autorelabel并重新启动。 不幸的是，这并没有解决手头的问题。 我将如何解决这个问题？

如果你想以简单的方式为MongoconfigurationSELINUX，可以在你的/var/log/audit/audit.log上试试audit2why ，看看哪些违规将被拒绝，并用audit2allow构build自定义策略。 它在80％的事件中起作用。
如果您仍然有问题 – 运行audit2why并手动修复其他问题。 也许我们可以帮助你在这一步。
