2 br-ex 변경·적용

• ※ 주의. 네트워크 재시작시 접속이 끊어질 수 있음

[root@controller ~]# ifconfig br-ex | head -2
br-ex: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.43.233  netmask 255.255.255.0  broadcast 192.168.43.255

[root@controller ~]# vi /etc/sysconfig/network-scripts/ifcfg-br-ex

#IPADDR=192.168.43.233

[root@controller ~]# vi /etc/sysconfig/network-scripts/ifcfg-br-ex

[root@controller ~]# ifconfig br-ex | head -2
br-ex: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.43.200  netmask 255.255.255.0  broadcast 192.168.43.255

3 변수 설정

[root@controller ~]# OLD_IP=192.168.43.233
[root@controller ~]# NEW_IP=192.168.43.200
[root@controller ~]# echo OLD_IP=[$OLD_IP], NEW_IP=[$NEW_IP]
OLD_IP=[192.168.43.233], NEW_IP=[192.168.43.200]
