Note: Before configuring bridge under CentOS7, now after changing bridge mode to normal mode, you can still see a lot of junk information when viewing the network card. If you want to completely delete the network card configuration information you don't want, the operation is as follows:

[root@linux-node1 ~]# ip add list1: lo: mtu 65536 qdisc noqueue state UNKNOWN qlen 1 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever2: eth0: mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:0c:29:9b:7d:d6 brd ff:ff:ff:ff:ff:ff inet 10.10.10.11/24 brd 10.10.10.255 scope global eth0 valid_lft forever preferred_lft forever inet6 fe80::20c:29ff:fe9b:7dd6/64 scope link valid_lft forever preferred_lft forever4: virbr0: mtu 1500 qdisc noqueue state DOWN qlen 1000 link/ether 52:54:00:f4:24:05 brd ff:ff:ff:ff:ff:ff inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0 valid_lft forever preferred_lft forever5: virbr0-nic: mtu 1500 qdisc pfifo_fast master virbr0 state DOWN qlen 1000 link/ether 52:54:00:f4:24:05 brd ff:ff:ff:ff:ff:ff
