Linux基础教程学习笔记之修改网络配置

RHEL7中修改网络配置:
systemctl status NetworkManager 
可使用startx 启动图形界面, 对网络配置有两种方法:
1,添加一套配配置方案
2,修改原有配置方案
具体步骤:
nmcli device show

  nmcli connection show
  nmcli connection "system0"
  nmcli connection show --active
2. 增加一套配置
  nmcli connection add con-name "dhcp-eth0" type ethernet ifname eth0
  nmcli connection add con-name "static-eth0" type ethernet ifname eth0 autoconnect ip4
  10.10.10.1/24 gw4 10.10.10.254
  nmcli conn down "system eth0"
  nmcli conn up "static-eth0"
  nmcli conn sh --active
  nmcli conn sh "system eth0" | grep -i autoconnect
  nmcli conn delete dhcp-eth0/static-eth0
3. 修改DNS
  nmcli conn modify "new" ipv4.dns 172.25.254.254
  hostnamectl set-hostname server1.example.com
