配置bonding驱动
(实践该步骤未做,便可用)
vim /etc/modprobe.d/bond.conf
alias bond0 binding
options bond0 miimon=100 mode=1
重启网络服务
service network restart
查看bond0生效
cat /proc/net/bonding/bond0
配置dns
vim /etc/resolv.conf
nameserver 202.106.0.20
centos 7默认启动时没有加载bonding模块
复制代码
# 查看bonding模块详细信息
modinfo bonding

# 配置系统启动时加载bonding模块
vim /etc/sysconfig/modules/bonding.modules
#!/bin/sh
/sbin/modinfo -F filename bonding > /dev/null 2>&1
if [ $? -eq 0 ];then
/sbin/modprobe bonding
fi
# 设置执行权限
chmod 755 /etc/sysconfig/modules/bonding.modules
