CentOS下创建网桥

Posted 2022-08-04 chengkanghua

 

说明：以下创建的是永久网桥，即重启后依然生效。

0、安装网桥的依赖

yum -y install tunctl bridge-utils

1、创建网桥配置文件

UUID=`uuidgen`
cat <<EOF > /etc/sysconfig/network-scripts/ifcfg-br0
TYPE="Bridge"
UUID="$UUID"
DEVICE="br0"
ONBOOT="yes"
EOF

2、修改原有网卡配置文件

cat <<EOF > /etc/sysconfig/network-scripts/ifcfg-eth0
TYPE="Ethernet"
DEVICE="eth0"
ONBOOT="yes"
BRIDGE=br0           
EOF

3、配置静态IP地址

cat <<EOF >> /etc/sysconfig/network-scripts/ifcfg-br0
BOOTPROTO="static"
IPADDR="192.168.1.10"
NETMASK="255.255.255.0"
GATEWAY="192.168.1.1"
EOF

4、重启网络

service network restart

5、网桥的显示

brctl show
