rocky8 中配置静态IP

001、查看系统信息

[root@localhost ~]# hostnamectl
   Static hostname: localhost.localdomain
         Icon name: computer-vm
           Chassis: vm
        Machine ID: 0f5ac3970da4429fa028c356ef25e662
           Boot ID: 5012d6e8a2084e5bb03d46166d4550ca
    Virtualization: vmware
  Operating System: Rocky Linux 8.10 (Green Obsidian)
       CPE OS Name: cpe:/o:rocky:rocky:8:GA
            Kernel: Linux 4.18.0-553.el8_10.x86_64
      Architecture: x86-64

002、进入网卡配置文件所在的目录

[root@localhost ~]# cd /etc/sysconfig/network-scripts/
[root@localhost network-scripts]# ls
ifcfg-ens160
[root@localhost network-scripts]# 

003、编辑网卡配置文件如下，让后保存退出

TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=eui64
NAME=ens160
UUID=9a82746f-d9b3-4152-87ee-9483e45c3842
DEVICE=ens160
ONBOOT=yes
IPADDR=192.168.30.133
NETMASK=255.255.255.0
GATEWAY=192.168.30.2
DNS1=119.29.29.29
DNS2=8.8.8.8

004、调整网络适配器模式

 005、重启网络服务

[root@localhost network-scripts]# ifconfig | head          ## 查看IP
ens160: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500

[root@localhost network-scripts]# nmcli connection reload           ## 重新连接网卡
[root@localhost network-scripts]# ifconfig | head                   ## ip生效，但是无法联网，为啥？
ens160: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500

        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 825  bytes 52873 (51.6 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
[root@localhost network-scripts]# ping -c www.baidu.com             ## 无法联网
ping: bad number of packets to transmit.

006、

[root@localhost network-scripts]# nmcli connection up ens160            ## 网卡生效
