动态IP地址
1 2 3 4 5 6 7 8 9 10 | DEVICE=eth0 ONBOOT=yes USERCTL=no BOOTPROTO=dhcp HWADDR=00:0c:29:97:f1:5b TYPE=Ethernet PEERDNS=yes IPV6INIT=no |
图形界面配置
1 2 3 4 | [root@rhel6 ~]# export LANG=C [root@rhel6 ~]# setup [root@rhel6 ~]# |
单个网卡添加多个IP
可以作为VIP进行漂移。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | -- 单个网卡添加多个IP(注意子网掩码需要和宿主网卡一样) ifconfig eth0:1 192.168.59.136/24 ifconfig eth0:1 192.168.59.131 netmask 255.255.255.0 up ifconfig eth0:1 192.168.59.132 netmask 255.255.255.0 up ifconfig eth0:1 172.72.6.56/16 netmask 255.255.0.0 up ifup eth0:0 ip addr add 172.72.6.56/16 dev eth0 label eth0:1 -- 编辑： /etc/sysconfig/network-scripts/ifcfg-eth0:1 修改DEVICE=eth0:1和IPADDR=192.168.59.131 -- 删除的话： ip addr del 192.168.59.135/24 dev eth0 ip addr del 172.72.6.56/16 dev eth0 |

若是删除的时候报错“RTNETLINK answers: Cannot assign requested address”，请检查子网掩码是否配置合适。
删除网卡重新添加
若还有问题，可删掉网卡重新添加，请参考：https://www.xmmup.com/dbbao51centos7xiugaiwangkamingcheng.html
