STP=yes

IPADD R=192.168.1.144

NETMA SK=255.255.255.0

GATEW AY=192.168.1.1

3、重启相关服务以及关闭相关服务

#syste mctl stop Netwo rkMan ager

#syste mctl disab le Netwo rkMan ager

#syste mctl resta rt netwo rk b r0正常启动能够正常访问该机器即可再用下面命令查看有即可#brctl show bridg e name bridg eid STPenabl edinter faces br08000.000c2 9ebab 05 yeseno16 77773 6

4、修改doc ker配置文件修改桥接的网卡以及I P分配范围

#vim/etc/sysco nfig/docke r

将

修改为

OPTIO NS='--sel in ux-enabl ed-b=br0--fixed -cidr=192.168.1.192/26'重新启动d ocker

#syste mctl stop docke r.servi ce

#syste mctl start docke r.servi ce

5、启动doc ker实例

#docke r run -i -tcento s/bin/bash

#ipaddrshoweth0
