Configure the Linux IP, network, etc.

Before with Ubuntu. Think of CentOS is also so configuration, the results copied down, start error haha ... Search online to find CentOS configuration requires a lot of files. Forget about the next reference

Ubuntu, so configure

The CentOS configuration requires the content to be set in multiple files, and the parameter variable needs to be equal to "=", which is different from Ubuntu, refer to Http://www.21andy.com/new/20100227/1717.html

First, CentOS modified IP address

Modify the configuration file for the IP address of the corresponding network card
# Vi/etc/sysconfig/network-scripts/ifcfg-eth0
Modify the following content
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=12.168.1.2 #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 =192.168.1.0 #网卡对应的网络地址
Onboot=yes #系统启动时是否设置此网络接口, when set to Yes, activates the device when the system starts

Second, CentOS modify the Gateway
Modify the configuration file for the gateway for the corresponding network card
[[Email protected]]# vi/etc/sysconfig/network
Modify the following content
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=192.168.1.1 (Sets the IP address of the gateway for the native connection. For example, the gateway is 10.0.0.2)

Third, CentOS modified DNS
Modify the DNS configuration file for the corresponding NIC
# vi/etc/resolv.conf
Modify the following content
NameServer 8.8.8.8 #google域名服务器

Iv. Restarting the network configuration
# Service Network Restart
