2. Find the configuration file we need to modify
Use the ls command to list the files in this directory. Among them, the file "ifcfg-ens33" (red box) is the network configuration file we need to modify.
3. Modify the configuration file
Use vim command (vi command is also available), to configure the file, we need to modify BOOTPROTO="static", that is, change dhcp to static, modify ONBOOT="yes", which means to set the network card to be enabled at boot, and add
below the text.IPADDR=192.168.0.230 #staticIP
GATEWAY=192.168.0.1 #Default Gateway
NETMASK=255.255.255.0 #Subnet Mask
DNS1=192.168.0.1 #DNS Configuration
DNS2=8.8.8.8 #GoogleAddress
The red box is the modified content, and the purple box is the content that needs to be added.
ESC WQ, save and exit!
4. Restart the network service
Use the service network restart command to restart the network service. (The red box is the command to restart the network service, and the blue box is the status of restarting the network service)
