Centos8重啟網絡服務

注：本文基於CentOS 8.3編寫

CentOS 7中支持network.service和NetworkManager.service 2種方式配置網絡，而在CentOS 8中已經廢棄network.service，需要通過NetworkManager.service配置網絡。因此通過systemctl restart network已經無法使用了。

[root@localhost ~]# cat /etc/redhat-release 
CentOS Linux release 8.3.2011
[root@localhost ~]# systemctl restart network
Failed to restart network.service: Unit network.service not found.

方法一:

使用nmcli命令，需要兩條指令，先加載配置，然后應用

[root@localhost ~]# nmcli c reload
[root@localhost ~]# nmcli c up ens33
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/9)

方法二:

使用ifdown和ifup

[root@localhost ~]# ifdown ens33;ifup ens33 
Connection 'ens33' successfully deactivated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/9)
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/10)
