MongoDB 的 SELinux 设置

我正在尝试从 mongodb.org 存储库在 CentOS 7.2 上安装 MongoDB。到目前为止一切都很好，但是主机已经为所有 MongoDB 数据文件创建了一个辅助磁盘 (/mongo)。这与 SELinux 权限冲突，导致 MongoDB 无法启动。我已经开始运行了setenforce 0，但这并不是我真正想要运行生产服务器的方式。

我有相当多的 Linux 经验，但我所有的 SELinux 经验只是将其关闭。我找到了这个 CentOS SELinux 教程，它让我想到了运行

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？
