Static IP settings for Centos7 Learning

Static IP settings for Centos7 Learning

This course is intended for Centos 7.0.1406!

1. Edit the ifcfg-eth0 file, vim is minimized when the installation is not installed, you need to install it on your own is not described.

# vim /etc/sysconfig/network-scripts/ifcfg-eth0

2. Modify the following content:

BOOTPROTO = "static" # Change dhcp to static ONBOOT = "yes" # enable this configuration at startup IPADDR = 192.168.7.106 # static IPGATEWAY = 192.168.7.1 # Default Gateway NETMASK = 255.255.255.0 # subnet mask DNS1 = 192.168.7.1 # DNS Configuration

3. modified results

#] # Cat/etc/sysconfig/network-scripts/ifcfg-eth0HWADDR = "00: 15: 5D: 07: F1: 02 "TYPE =" Ethernet "BOOTPROTO =" static "# Change dhcp to static DEFROUTE =" yes "PEERDNS =" yes "PEERROUTES =" yes "IPV4_FAILURE_FATAL =" no "4256init =" yes ""Listen 6_autoconf =" yes "comment 6_defroute =" yes "comment 6_peerdns =" yes "comment 6_peerroutes =" yes "comment =" no "NAME =" eth0 "UUID =" bb3a302d-dc46-461a-881e-d46cafd0eb71 "ONBOOT =" yes "# enable IPADDR = 192.168.7.106 # static IPGATEWAY = 192.168.7.1 # Default Gateway NETMASK = 255.255.255.0 # subnet mask DNS1 = 192.168.7.1 # DNS Configuration

4. Restart the network service.

# service network restart

5. Check the modified results. Centois 7 does not use ifconfig, but uses ip commands to view network information.
