linux系统添加网卡设备及搭建阿里yum源

网卡的使用 [root@cobbler cobbler]# nmcli connection add type ethernet con-name eth1 ifname eth1 连接“eth1”(9647a0f6-b44d-4a2d-b420-984e61352c30) 已成功添加。 #添加网卡eth1 [root@cobbler cobbler]# nmcli connection delete eth1 # 删除网卡 成功删除连接 ‘eth1’（9647a0f6-b44d-4a2d-b420-984e61352c30）。

[root@cobbler cobbler]# nmcli connection down eth0 #关闭网卡 成功取消激活连接 ‘eth0’（D-Bus 活动路径：/org/freedesktop/NetworkManager/ActiveConnection/5） [root@cobbler cobbler]# nmcli connection up eth0 #激活网卡 连接已成功激活（D-Bus 活动路径：/org/freedesktop/NetworkManager/ActiveConnection/6）

搭建阿里yum源，虚拟机要桥接网卡配置网关，ping通外网
