网卡配置文件 及 bridge的静态配置
centos7 Bridge配置
[[email protected] ~]# cd /etc/sysconfig/network-scripts/
[[email protected] network-scripts]# vim ifcfg-ens33
- TYPE="Ethernet"
- BOOTPROTO="static"
- DEFROUTE="yes"
- IPV4_FAILURE_FATAL="no"
- IPV6INIT="yes"
- IPV6_AUTOCONF="yes"
- IPV6_DEFROUTE="yes"
- IPV6_FAILURE_FATAL="no"
- IPV6_ADDR_GEN_MODE="stable-privacy"
- NAME="ens33"
- UUID="44dad4b3-8c0b-4cd7-aa95-8d05168b0bcb"
- DEVICE="ens33"
- IPV6_PEERDNS="yes"
- IPV6_PEERROUTES="yes"
- IPV6_PRIVACY="no"
- ONBOOT=yes
- #IPADDR=192.168.1.151
- #GATEWAY=192.168.1.1
- #PREFIX=24
- #DNS1=114.114.114.114
- BRIDGE=br0
[[email protected] network-scripts]# vim ifcfg-br0
- TYPE=Bridge
- BOOTPROTO=static
- DEFROUTE=yes
- PEERDNS=yes
- PEERROUTES=yes
- IPV4_FAILURE_FATAL=no
- IPADDR=192.168.1.151
- GATEWAY=192.168.1.1
- PREFIX=24
- DNS1=114.114.114.114
- DEVICE=br0
- ONBOOT=yes
注意： TYPE 为 Bridge，不是Ethernet
BOOTPROTO 为 static，需要添加 IPADD=XXXX 配置IP地址及网关
DEVICE 为设备名称
以上三项为必有项。
ONBOOT 系统启动时，是否启动。yes 启动，no 不启动。 no时需要手动启动 ifup br0
创建好网桥配置文件后，重启网络或br0
# service network restart
或
#ifup br0
最好使用后者，前者会重启所有网络，由于其他网卡配置文件不正确，导致重启失败。
通过 命令查看 网桥是否存在：
#ip a
或 # ifconfig
通过 brctl show 查看网卡是否挂载到 网桥上。
如果没有brctl 命令
yum install bridge-utils -y
[[email protected] network-scripts]# brctl show bridge name bridge id STP enabled interfaces br0 8000.000c295ce379 no ens33 veth1pl4004 docker0 8000.02425b035439 no vethc4a2cc5

此时你会看到容器中新增加了一块网卡
