centos 网卡无法链接的问题

[root@localhost~]# systemctl stop NetworkManager
[root@localhost~]# 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.
[root@localhost~]# service network restart

重启网络
systemctl restart network

 

 

1. 执行下面的命令，将导致ifconfig出现ens33，但没有ip地址

ifconfig ens33 up

2. 执行下面的命令

systemctl stop NetworkManager
ifup ens33

3. 重启网络

systemctl restart network.service

4. 此时执行ifconfig发现ens33已经有了ip地址

5. 最后一步：永久关闭NetworkManager，保证下次开机ens33会自启动

systemctl disable NetworkManager
