Linux CentOS 7 多网卡配置bond模式 bond1 bond5 bond6

网卡绑定mode共有七种(0~6) bond0、bond1、bond2、bond3、bond4、bond5、bond6

常用的有四种

mode=0：(balance-rr) Round-robin policy(平衡抡循环策略)平衡负载模式，有自动备援，但需要”Switch”支援及设定。

mode=1，(active-backup) Active-backup policy(主-备份策略)只有一个设备处于活动状态，当一个宕掉另一个马上由备份转换为主设备。mac地址是外部可见得，从外面看来，bond的MAC地址是唯一的。

mode=5，(balance-tlb) Adaptive transmit load balancing(适配器传输负载均衡)不需要任何特别的switch(交换机)支持的通道bonding。

mode=6，(balance-alb) Adaptive load balancing(适配器适应性负载均衡)该模式包含了balance-tlb模式，同时加上针对IPV4流量的接收负载均衡(receive load balance, rlb)，而且不需要任何switch(交换机)的支持。接收负载均衡是通过ARP协商实现的

mode=1，(active-backup) Active-backup policy(主-备份策略)

在Centos 7中，我们可以使用modinfo bonding 命令查看bonding模块的信息，默认情况下bonding模块没有被加载

以root用户登录，输入如下的命令进行开启加载bonding模块

modprobe --first-time bonding //--first-time Fail if module already inserted or removed

cat /etc/sysconfig/network-scripts/ifcfg-bond1

DEVICE=bond1

CentOS7手动配置bond6(balance-alb) Adaptive load balancing(适配器适应性负载均衡)

1、在Centos 7中，我们可以使用modinfo bonding 命令查看bonding模块的信息，默认情况下bonding模块没有被加载

以root用户登录，输入如下的命令进行开启加载bonding模块

modprobe --first-time bonding //--first-time Fail if module already inserted or removed

2、创建bond0配置文件，创建/etc/sysconfig/network-scripts/ifcfg-bond0文件，加入如下内容

cat /etc/sysconfig/network-scripts/ifcfg-bond0

DEVICE=bond0

TYPE=Bond

BONDING_MASTER=yes

BOOTPROTO=none

DEFROUTE=yes

IPV4_FAILURE_FATAL=no

IPV6INIT=yes

IPV6_AUTOCONF=yes

IPV6_DEFROUTE=yes

IPV6_FAILURE_FATAL=no

NAME="bond0"

IPADDR=192.168.199.223

PREFIX=24

ONBOOT=yes

BONDING_OPTS="resend_igmp=1 updelay=0 use_carrier=1 miimon=100 downdelay=0 xmit_hash_policy=0 primary_reselect=0 fail_over_mac=0 arp_validate=0 mode=balance-alb arp_interval=0 ad_select=0"

PEERDNS=yes

PEERROUTES=yes

IPV6_PEERDNS=yes

IPV6_PEERROUTES=yes

其中BONDING_OPTS指定bonding的模式，其中10.101.230.30/27将作为bond0的ip地址

3、配置e网卡配置文件，文件位于/etc/sysconfig/network-scripts/目录

vi ifcfg-eno16777736

TYPE=Ethernet

BOOTPROTO=none 修改

DEFROUTE=yes

PEERDNS=yes

PEERROUTES=yes

IPV4_FAILURE_FATAL=no

IPV6_AUTOCONF=yes

IPV6_DEFROUTE=yes

IPV6_PEERDNS=yes

IPV6_PEERROUTES=yes

NAME=eno1

UUID=26ea0bd1-0837-4b1a-9039-f147abd19632

DEVICE=eno16777736

#以下两项为新增配置选项

MASTER=bond0

systemctl restart network.service //重启网络服务
