如何在RHEL上配置网络绑定

TYPE=Ethernet
BOOTPROTO=none
DEVICE=ens192
ONBOOT=yes
MASTER=bond0
SLAVE=yes

配置第二个子接口

修改你希望添加到绑定中的第二个子接口。请根据你的实际环境使用合适的接口名。

vi /etc/sysconfig/network-scripts/ifcfg-ens224

TYPE=Ethernet
BOOTPROTO=none
DEVICE=ens224
ONBOOT=yes
MASTER=bond0
SLAVE=yes

重启网络服务

重启网络服务以激活绑定接口。

systemctl restart network

验证绑定配置

你可以借助 ip 命令来查看绑定接口以及其子接口的情况。可以看到，bond0现在已启动并在运行。

查阅绑定接口状态

检查以下文件，你可以看到绑定接口及其子接口的详细信息。输出结果应该看起来很不错，我们能看到诸如绑定模式，MII 状态，MII 轮询间隔，LACP 速率，端口数量等信息。

容错/冗余测试

为了验证容错性和连接速度，你可以逐个断开接口，然后检查服务器是否仍旧可达。
