修改IP保存成shell文件，执行[ol]

我需要添加这2个 IP 到我的服务器 198.100.XXX.61 & 198.100.XXX.62

有高手可以出手帮忙吗?

国外的老大教我

[ol]

# up ip addr add 198.100.XXX.61/32 dev eth0

# up ip addr add 198.100.XXX.62/32 dev eth0[/ol]复制代码

然后
ip address show eth0

[ol]

2: eth0:
mtu 1500 qdisc pfifo_fast state UP group default qlen 1000

link/ether fa:16:3e:9c:00:90 brd ff:ff:ff:ff:ff:ff

inet 144.217.XXX.28/32 brd 144.217.84.28 scope global eth0

valid_lft forever preferred_lft forever

inet 198.100.XXX.61/32 scope global eth0

valid_lft forever preferred_lft forever

inet 198.100.XXX.62/32 scope global eth0

valid_lft forever preferred_lft forever

inet6 fe80::f816:3eff:fe9c:90/64 scope link

valid_lft forever preferred_lft forever[/ol]复制代码

可是外面还是无法 ping 通

不要加在eth0，要用eth0.1这种

okhost · 发表于 2016-11-26 12:55:34

http://docs.ovh.ca/en/guides-network-bridging.html
For example:

IP of your server : 123.456.789.012
Gateway’s IP is your server’s main IP ending in .254
So the gateway’s IP is: 123.456.789.254

okhost · 发表于 2016-11-25 21:57:00

具体的配置如下：
centos7 下面
1.建立一个eth0:0 可以copy ifcfg-eth0的配置做修改
DEVICE=eth0:0 (网卡名 )
BOOTPROTO=static
IPADDR=XXX.XXX.XXX.NEWIP (OVH分给你的新IP)
NETMASK=255.255.255.255 （必须是这个好像）
ONBOOT=yes
GATEWAY=XXX.XXX.MAINIP.254 (main IP 最后一位改成254)
然后ifup eth0:0
完事了
这是绑在母鸡里的如果是绑在VPS里面的要有其它的做法
