redhat9中配置静态IP（nmtui命令）

1、查看系统

[root@PC1 network-scripts]# hostnamectl
 Static hostname: PC1
       Icon name: computer-vm
         Chassis: vm 
      Machine ID: 43d69e6f6dc9444d83a0047a6a16c037
         Boot ID: 60f34b965e934969ac756f9f953defd9
  Virtualization: vmware
Operating System: Red Hat Enterprise Linux 9.0 (Plow)     
     CPE OS Name: cpe:/o:redhat:enterprise_linux:9::baseos
          Kernel: Linux 5.14.0-70.13.1.el9_0.x86_64
    Architecture: x86-64
 Hardware Vendor: VMware, Inc.
  Hardware Model: VMware Virtual Platform

2、查看当前IP

[root@PC1 network-scripts]# ifconfig | head
ens160: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.3.123  netmask 255.255.255.0  broadcast 192.168.3.255
        inet6 fe80::20c:29ff:fe97:a973  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:97:a9:73  txqueuelen 1000  (Ethernet)
        RX packets 1056  bytes 1375388 (1.3 MiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 1004  bytes 74434 (72.6 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536

3、在终端输入：nmtui

[root@PC1 network-scripts]# nmtui

14、重启网络服务

[root@PC1 network-scripts]# nmcli c reload 
[root@PC1 network-scripts]# nmcli c up ens160 
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/3)

15、检查，测试网路：

[root@PC1 network-scripts]# ifconfig |  head
ens160: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.3.66  netmask 255.255.255.0  broadcast 192.168.3.255
        inet6 fe80::20c:29ff:fe97:a973  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:97:a9:73  txqueuelen 1000  (Ethernet)
        RX packets 1100  bytes 1379044 (1.3 MiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 1087  bytes 82141 (80.2 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
