Docker——桥接网络配置_windows系统 docker怎么桥接网卡-优快云博客

本文详细介绍了如何在Linux系统中通过编辑ifcfg-eth0和创建ifcfg-br0文件实现网络桥接，包括修改设备类型、网络参数及重启网络服务的过程。

[root@localhost ~]# cd /etc/sysconfig/network-scripts/
[root@localhost network-scripts]# ls
ifcfg-eth0   ifdown-ib    ifdown-ppp     ifup-aliases  ifup-ipv6   ifup-ppp       init.ipv6-global
ifcfg-lo     ifdown-ippp  ifdown-routes  ifup-bnep     ifup-isdn   ifup-routes    net.hotplug
ifdown       ifdown-ipv6  ifdown-sit     ifup-eth      ifup-plip   ifup-sit       network-functions
ifdown-bnep  ifdown-isdn  ifdown-tunnel  ifup-ib       ifup-plusb  ifup-tunnel    network-functions-ipv6
ifdown-eth   ifdown-post  ifup           ifup-ippp     ifup-post   ifup-wireless
[root@localhost network-scripts]# cp ifcfg-eth0 ifcfg-br0


[root@localhost network-scripts]# vi ifcfg-eth0
DEVICE=eth0
HWADDR=00:0C:29:DB:B2:28
TYPE=Ethernet
UUID=b2268aab-fa2e-49e9-bd67-2572f29e5790
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static
IPADDR=192.168.1.179
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
DNS1=114.114.114.114
DNS2=8.8.4.4

增加BRIDGE=br0，删除IPADDR、NETMASK、GATEWAY、DNS


DEVICE=eth0
HWADDR=00:0C:29:DB:B2:28
TYPE=Ethernet
UUID=b2268aab-fa2e-49e9-bd67-2572f29e5790
ONBOOT=yes
BRIDGE=br0
BOOTPROTO=none
#IPADDR=192.168.1.179
#NETMASK=255.255.255.0
#GATEWAY=192.168.1.1
#DNS1=114.114.114.114
#DNS2=8.8.4.4

保存退出


[root@localhost network-scripts]# vi ifcfg-br0
DEVICE=eth0
HWADDR=00:0C:29:DB:B2:28
TYPE=Ethernet
UUID=b2268aab-fa2e-49e9-bd67-2572f29e5790
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static
IPADDR=192.168.1.179
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
DNS1=114.114.114.114
DNS2=8.8.4.4

修改DEVICE为br0，Type为Bridge，把eth0的网络设置设置到这里来


DEVICE=br0
TYPE=Bridge
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.1.179
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
DNS1=114.114.114.114
DNS2=8.8.4.4

保存退出

[root@localhost network-scripts]# service network restart

这一步我出现了问题，不过重启宿主机后就OK了。
