1. Modify the network adapter configuration edit: Vi/etc/sysconfig/network-scripts/ifcfg-eth0, the content information is as follows:
Device=eth0 #描述网卡对应的设备别名, for example, in Ifcfg-eth0 file it is eth0
Bootproto=static #设置网卡获得ip地址的方式, the possible options are static,dhcp or BOOTP, corresponding to statically specified IP addresses, IP addresses obtained through the DHCP protocol, IP addresses obtained through the BOOTP protocol
broadcast=192.168.0.255 #对应的子网广播地址
HWADDR=00:07:E9:05:E8:B4 #对应的网卡物理地址
ipaddr=12.168.0.33 #如果设置网卡获得 IP address is statically specified, this field specifies the IP address of the NIC
netmask=255.255.255.0 #网卡对应的网络掩码
network=192.168.0.0 #网卡对应的网络地址
2. Modify the Gateway Configuration
Edit: Vi/etc/sysconfig/network, the content information is as follows:
Networking=yes (Indicates whether the system uses a network and is generally set to Yes.) If set to no, the network cannot be used, and many system services programs will not start.
Hostname=centos (Set the hostname of this machine, the host name set here should correspond to the hostname set in/etc/hosts)
gateway=192.168.0.1 (Sets the IP address of the gateway for the native connection. )
I'm editing this here. The first three items are already default, so only the gateway is added.
3. Modify the DNS configuration
EDIT: vi/etc/resolv.conf modified as follows:
Domain ""
NameServer 192.168.10.1
NameServer 0.0.0.0
NameServer is the DNS server IP address, the first is the preferred one, the second is the standby.
4. Restart the Network Service
Execute command:
Service network restart or/etc/init.d/network restart
CentOS Set Static IP
