Centos 6.x 单网卡双IP配置
主IP设置
|
1 2 3 4 5 6 7 |
# vi /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 BOOTPROTO=static IPADDR=23.239.208.87 NETMASK=255.255.255.0 GATEWAY=23.239.208.1 onboot=YES |
新ip配置
|
1 2 3 4 5 6 7 |
# vi /etc/sysconfig/network-scripts/ifcfg-eth0:0 DEVICE=eth0:0 BOOTPROTO=static IPADDR=23.239.208.175 NETMASK=255.255.255.0 GATEWAY=23.239.208.1 onboot=YES |
新增ip，只需要在/etc/sysconfig/network-scripts/ifcfg-eth0基础上按ifcfg-eth0:0、ifcfg-eth0:1增加即可。
