How to configure ip address in centos system

The network configuration is saved in the network-scripts folder. We first go to the directory and use the following command:

cd /etc/sysconfig/network-scripts/

(recommended Tutorial:centos usage tutorial)

Then we look at the files in the directory and find an ifcfg-ensxxx network configuration file. If not, create one. Here is ifcfg-ens33

Use vim to open the ifcfg-ens33 file and modify the relevant configuration

After modifying the configuration file, the content is as follows:

TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=static #这里改成static代表设置静态ip DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no IPV6_ADDR_GEN_MODE=stable-privacy NAME=ens33 UUID=99c45215-02e8-4e93-baee-8760f25ee478 DEVICE=ens33 ONBOOT=yes #启动自动运行 ZONE=public IPADDR=192.168.1.19 NETMASK=255.255.255.0 GETEWAY=192.168.1.1 DNS1=192.168.1.1 PREFIX=24 GATEWAY=192.168.0.1
