centos7 network[3326]: RTNETLINK answers: File exists

本文介绍了如何在CentOS 7中解决NetworkManager与传统网络服务之间的冲突问题,包括停止NetworkManager服务、重启网络服务及禁用NetworkManager。

[root@centos7 network-scripts]# service NetworkManager stop
Redirecting to /bin/systemctl stop  NetworkManager.service
[root@centos7 network-scripts]# systemctl stop NetworkManager
[root@centos7 network-scripts]# systemctl restart network
[root@centos7 network-scripts]# systemctl disable NetworkManager
Removed symlink /etc/systemd/system/multi-user.target.wants/NetworkManager.service.
Removed symlink /etc/systemd/system/dbus-org.freedesktop.NetworkManager.service.
Removed symlink /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service.

根本原因是两个网络服务有冲突
