我产生了一个具有单个网络接口的AWS实例(Ubuntu)。 我已经附加了两个弹性IP和两个私有IP。
主要私有IP :172.30.175.22
次要私有IP :172.30.175.23
在附加了辅助IP之后,我执行了以下命令:
sudo ip addr add 172.30.175.23/19 dev eth0
我想知道是否需要使用eth0:0
而不是eth0
sudo ip addr
的输出如下:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9001 qdisc pfifo_fast state UP group default qlen 1000

valid_lft forever preferred_lft forever
inet6 fe80::1e:a3ff:fe64:254a/64 scope link
valid_lft forever preferred_lft forever
但是ifconfig
没有显示辅助IP:

我是否正确完成或当前设置正确。我需要澄清。
