rocky9.1中如何配置静态IP

001、系统

[root@PC1 ~]# hostnamectl
 Static hostname: PC1
       Icon name: computer-vm
         Chassis: vm 🖴
      Machine ID: 0701dfe1316f4cd6be6f958130674e6f
         Boot ID: 541d72ac4ba142c4a639b3406d5037b5
  Virtualization: vmware
Operating System: Rocky Linux 9.1 (Blue Onyx)      
     CPE OS Name: cpe:/o:rocky:rocky:9::baseos
          Kernel: Linux 5.14.0-162.6.1.el9_1.x86_64
    Architecture: x86-64
 Hardware Vendor: VMware, Inc.
  Hardware Model: VMware Virtual Platform

002、进入 /etc/NetworkManager/system-connections/ 目录

[root@PC1 ~]# cd /etc/NetworkManager/system-connections/
[root@PC1 system-connections]# ls
ens160.nmconnection
[root@PC1 system-connections]#

003、修改配置文件

[root@PC1 system-connections]# vim ens160.nmconnection

在ipv4下修改如下内容，然后保存退出：

[ethernet]

[ipv4]
address1=192.168.254.30/24,192.168.254.2  ## ip，子网掩码，网关
dns=119.29.29.29;114.114.114.114;         ## DNS
may-fail=false
method=manual                             ## 手动IP

004、加载配置文件

[root@PC1 system-connections]# ls
ens160.nmconnection
[root@PC1 system-connections]# nmcli connection load  /etc/NetworkManager/system-connections/ens160.nmconnection

005、激活配置文件

[root@PC1 system-connections]# ls
ens160.nmconnection
[root@PC1 system-connections]# nmcli connection up  /etc/NetworkManager/system-connections/ens160.nmconnection 
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/2)

006、查看IP

[root@PC1 system-connections]# ifconfig | head
ens160: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.254.30  netmask 255.255.255.0  broadcast 192.168.254.255
        inet6 fe80::20c:29ff:fe36:2755  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:36:27:55  txqueuelen 1000  (Ethernet)
        RX packets 731  bytes 87910 (85.8 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 888  bytes 76962 (75.1 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

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

007、测试网络

[root@PC1 system-connections]# ping -c 3 www.baidu.com
