This article mainly elaborates the method of modifying IP address in Centos7.
I. Enter the Network Profile Directory
First, make sure you operate under the root user. Enter the network-scripts directory of the network configuration file.
Two.Find the configuration file we need to modify
List the files in this directory using the LS command. Among them“ifcfg-ens33(red box) file, for the network configuration file we need to modify.
III. Modification of configuration files
UseVIM command(vi command can also be used). To configure the file, we need to modify it.BOOTPROTO=”static“That is to say, change DHCP to static and modify it.ONBOOT=”yes”This means that the network card is set to boot, and added under the text.
IPADDR=192.168.0.230# Static IP
GATEWAY=192.168.0.1 #Default gateway
NETMASK=255.255.255.0 #Subnet mask
DNS1=192.168.0.1 #DNS configuration
DNS2=18.104.22.168# Google Address
Red boxes are for modifying content, and purple boxes are for adding content.
IV. Restart Network Services
UseService network restart commandRestart network services. (The red box restarts the network service command and the blue box restarts the network service status)
5. View the effect of our changes
Because it’s now Centos7 so we use the new command, we typeIP addr for viewing。 (Red box is the view command, blue box is the network card status)
