CentOS configure network access
Introductionvi /etc/sysconfig/network-scripts/ifcfg-eth0 # 1. ONBOOT=no is changed to ONBOOT=yes whether it starts with the system# 2. BOOTPROTO=dhcp is changed to BOOTPROTO=static IP address allocation method, which is automatically allocated by the DHCP server , or manually configure
First, edit the network card configuration file
1 2 3 4 | vi /etc/sysconfig/network-scripts/ifcfg-eth0# 1. Change ONBOOT=no to ONBOOT=yes whether to start with the system # 2. BOOTPROTO=dhcp is modified to BOOTPROTO=static IP address allocation method, whether it is automatically allocated by the DHCP server or manually configured |
Add after the content of the ifcfg-eth0 file
1 2 3 4 5 6 | IPADDR=192.168.1.160 << IP NETMASK=255.255.255.0 << subnet mask GATEWAY=192.168.1.1 << gateway DNS1=202.96.134.133 DNS2=202.96.128.68 The DNS configuration is added according to the local network provider. I am here in Shenzhen, and I use the DNS of Shenzhen Telecom |
After adding, exit and save
2. Restart the network service
1 | service network restart |
3. DNS can also be configured in other files
1 2 3 4 5 6 | vi /etc/resolv.conf# join in nameserver 202.96.134.133 nameserver 202.96.128.68 # Exit save, restart network service service network restart |
Note: Actually /etc/resolv.conf is the DNS configuration information of the network card configuration file before it is automatically called
Fourth, test whether the network is connected
1 | ping www.baidu.com |
