Static IP settings for centos 7 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.
