Centos 7 Learning static IP settings

Original link: http://blog.csdn.net/johnnycode/article/details/40624403

This study is mainly for Centos 7.0.1406 version to learn to organize!

If you use VirtualBox to configure CentOS then please refer to my article CentOS 7 learning static IP settings (cont.)

1, edit the Ifcfg-eth0 file, vim minimized installation is not installed, need to install the self-description.

1. # Vim/etc/sysconfig/network-scripts/ifcfg-eth0

2, modify the following content

[plain] view plain copy

1. bootproto= "Static" #dhcp改为static
2. onboot= "Yes" #开机启用本配置
3. ipaddr=192.168.7.106 #静态IP
4. gateway=192.168.7.1 #默认网关
5. netmask=255.255.255.0 #子网掩码
6. dns1=192.168.7.1 #DNS Configuration

3. Effect after modification

1. #]# cat/etc/sysconfig/network-scripts/ifcfg-eth0  
2. hwaddr= "00:15:5d:07:f1:02"   
3. type= "Ethernet"   
4. bootproto= "Static" #dhcp改为static    
5. defroute= "yes"   
6. peerdns= "yes"   
7. peerroutes= "yes"   
8. ipv4_failure_fatal= "No"   
9. ipv6init= "yes"   
10. ipv6_autoconf= "yes"   
11. ipv6_defroute= "yes"   
12. ipv6_peerdns= "yes"   
13. ipv6_peerroutes= "yes"   
14. ipv6_failure_fatal= "No"   
15. name= "eth0"   
16. uuid= "bb3a302d-dc46-461a-881e-d46cafd0eb71"   
17. onboot= "yes" #开机启用本配置   
18. ipaddr=192.168.7.106 #静态IP   
19. gateway=192.168.7.1 #默认网关   
20. netmask=255.255.255.0 #子网掩码   
21. dns1=192.168.7.1 #DNS configuration  

4. Restart the Network Service

1. # Service Network Restart

5, see the effect after the change, Centois 7 no longer use ifconfig instead of using the IP command to view network information.
