A detailed example of Centos6 network configuration
Preface:
To implement permanent custom IP or to change DNS you need to modify the configuration file, mainly the following configuration file
etc/sysconfig/ ES11en-ES12en/ES13en-ES14en, in which ES15en-ES16en X represents the number of network card, 1 is generally the first block, that is, ES18en-eth0
Below is a description of the configuration project, showing the configuration files for custom IP and DNS
DEVICE=eth0# Network card device name
TYPE=Ethernet# Card type
UUID=06c04617-25d9-4a88-aab0-d8f0028f80ca# equipment UUID Serial number
ONBOOT=yes# Whether to start automatically or not
NM_CONTROLLED=yes# Whether be NetworkManager management
BOOTPROTO=none# Type of boot {none|dhcp}
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth0" # Network name
HWADDR=08:00:27:E5:F9:B4 #MAC address
IPADDR=192.168.1.140# The custom ip
PREFIX=24# Subnet mask
GATEWAY=192.168.1.1# The gateway
DNS1=192.168.1.1# The main DNS
DOMAIN=114.114.114.114
LAST_CONNECT=1430925668 # The last 1 Subconnection time
When using DHCP to automatically assign IP, as long as the
BOOTPROTO=none
Instead of
BOOTPROTO=dhcp
It is ok
After the modification, run the following command to restart the network service
[root@git network-scripts]# /etc/init.d/network restart
