4.18以上版本内核的操作系统配置bond

该脚本用于在Linux系统中配置bonding（网卡绑定），包括active-backup和balance-alb模式，设置IP地址，检查并添加默认网关，以及在启动、停止、重启和状态查询时执行相应操作。此外，还包括了针对不同系统版本（如RockyLinux8.6）的特定处理。

示例

添加bond

sudo /bin/nmcli con add type bond ifname bond0 mode active-backup miimon 100 

sudo /bin/nmcli con add type bond ifname bond0 mode balance-alb miimon 100 updelay $UPDELAY

配置ip等信息

 sudo  /sbin/ifconfig $DEVICE $IPADDR netmask $NETMASK >
 if [ "$GATEWAY" != "" ];then
			#同一网段已存在默认路由时 不能再进行路由添加 删除bond0
			FLAG=`/sbin/route -n | grep $DEVICE | grep $GATEWAY`

				DEST=`/sbin/route -n | grep $GATEWAY | awk '{ print $1 }'`
				if [ "$DEST" == "0.0.0.0" ];then
					del;
					return 1;
				fi
			fi

			#网络不可达时 删除bond0 
			sudo /sbin/route add default gw $GATEWAY dev $DEVICE > 
			if [ $? -ne 0 ];then 
				del;
				return 1;
			fi
