Centos7多硬盘绑定bond快速实践

ls /etc/sysconfig/network-scripts/ifcfg*

/etc/sysconfig/network-scripts/ifcfg-ens32 /etc/sysconfig/network-scripts/ifcfg-ens35

/etc/sysconfig/network-scripts/ifcfg-ens34 /etc/sysconfig/network-scripts/ifcfg-lo

三，所选路由器绑定Mode

多路由器总计有7种bondMode，这里直接除此以外mode=6 (balance-alb) Adaptive load balancing（适配器可操作性输出整体），该Mode不并不需要交换机支持

四、开始配备

1、加载bonding模块，并设置季于启动

[root@localhost ~]# lsmod | grep bonding

[root@localhost ~]# modprobe bonding

[root@localhost ~]# lsmod | grep bonding

bonding 152979 0

开业rc.local季于启动项

chmod +x /etc/rc.d/rc.local

在文件里面写入modprobe bonding

2、建立bond取而代之浪口处理程序并展开配备

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

DEVICE=bond0

NAME=bond0

TYPE=Bond

BONDING_MASTER=yes

IPADDR=192.168.30.250

PREFIX=255.255.255.0

GATEWAY=192.168.30.2

DNS1=114.114.114.114

ONBOOT=yes

BOOTPROTO=none

BONDING_OPTS="mode=6 miimon=100"

3、删减三块路由器的配备

vi /etc/sysconfig/network-scripts/ifcfg-ens32

DEVICE=ens32

ONBOOT=yes

BOOTPROTO=none

TYPE=Ethernet

MASTER=bond0

SLAVE=yes

vi /etc/sysconfig/network-scripts/ifcfg-ens34

DEVICE=ens34

ONBOOT=yes

BOOTPROTO=none

TYPE=Ethernet

MASTER=bond0

SLAVE=yes

vi /etc/sysconfig/network-scripts/ifcfg-ens35

DEVICE=ens35

ONBOOT=yes

BOOTPROTO=none

TYPE=Ethernet

MASTER=bond0

SLAVE=yes

4、再一加载取而代之浪络配备

注意：这一步会断取而代之浪！

nmcli connection reload && systemctl restart network.service

使用取而代之IP链接ssh

五、测试绑定是否有效期

cat /proc/net/bonding/bond0

紧接著ping测试，并禁用第一个路由器，此时会丢出一个包，取而代之浪络依然正常行驶
