我正在配置一个 Fedora 21 服务器，我已经根据以下LINK设置了静态 ip 和 dns

我正在使用编辑文件

vi /etc/resolv.conf

然后像上面提到的那样放置我的dns。一切正常。但是在我重新启动后，该文件被其原始内容覆盖：

# No nameservers found; try putting DNS servers into your
# ifcfg files in /etc/sysconfig/network-scripts like so:
#
# DNS1=xxx.xxx.xxx.xxx
# DNS2=xxx.xxx.xxx.xxx
# DOMAIN=lab.foo.com bar.foo.com

发生了什么以及如何阻止这种情况发生？

NetworkManager 正在覆盖它。您可以将其关闭并进入“手动”模式，那里有一些教程：http: //xmodulo.com/disable-network-manager-linux.html

使用以下命令防止 resolv.conf 或任何文件在重启后被覆盖

chattr -V +i filename

例如：chattr -V +i /etc/resolv.conf

要恢复更改，请使用以下命令：

chattr -i filename- 重新启用插入文件

chattr (Change Attribute) 是一个命令行 Linux 实用程序，用于设置/取消设置 Linux 系统中文件的某些属性，以保护重要文件和文件夹的意外删除或修改，即使您以 root 用户身份登录也是如此。

在 fedora 26 下man NetworkManager.conf，它说：

rc-manager
           Set the resolv.conf management mode. The default value depends on NetworkManager build options, and this version of NetworkManager was build with a default of "symlink". Regardless of this
           setting, NetworkManager will always write resolv.conf to its runtime state directory /var/run/NetworkManager/resolv.conf.

           symlink: If /etc/resolv.conf is a regular file, NetworkManager will replace the file on update. If /etc/resolv.conf is instead a symlink, NetworkManager will leave it alone. Unless the symlink
           points to the internal file /var/run/NetworkManager/resolv.conf, in which case the symlink will be updated to emit an inotify notification. This allows the user to conveniently instruct
           NetworkManager not to manage /etc/resolv.conf by replacing it with a symlink.

           file: NetworkManager will write /etc/resolv.conf as file. If it finds a symlink, it will follow the symlink and update the target instead.

           resolvconf: NetworkManager will run resolvconf to update the DNS configuration.

           netconfig: NetworkManager will run netconfig to update the DNS configuration.

           unmanaged: don't touch /etc/resolv.conf.

           none: deprecated alias for symlink.

似乎不需要更改任何配置文件。

我只是在那里放了一个符号链接，它就可以工作。
