CentOS 7 网卡bond配置

对p1p1 p1p2两张网卡做bond步骤

1)做之前请对各网卡配置进行备份

1 使用root账号登录服务器@H_502_15@

2 cp p1p1 p1p2 网卡的初始配置到tmp 目录下，进行备份。@H_502_15@

--------------------------------------------------------------@H_502_15@

[root@XACR-aliware04 ~]# cd /etc/sysconfig/network-scripts/@H_502_15@

[root@XACR-aliware04 network-scripts]# cp ifcfg-p1p1 /tmp@H_502_15@

[root@XACR-aliware04 network-scripts]# cp ifcfg-p1p2 /tmp@H_502_15@

--------------------------------------------------------------@H_502_15@

2)使用nmcli命令配置bond@H_502_15@

生成bond配置@H_502_15@

@H_502_15@

--------------------------------------------------------------
@H_502_15@

nmcli con add type bond ifname bond0 mode 1@H_502_15@

nmcli con add type bond-slave ifname p1p1 master bond0@H_502_15@

nmcli con add type bond-slave ifname p1p2 master bond0@H_502_15@

@H_502_15@

注：p1p1 p1p2 为物理网卡的名字@H_502_15@

@H_502_15@

bond的mode如下：@H_502_15@

balance-rr (0) --轮询模式（bond默认的模式）@H_502_15@

active-backup (1) --主备模式（常用）@H_502_15@

balance-xor (2) @H_502_15@

broadcast (3)@H_502_15@

802.3ad (4) --聚合模式@H_502_15@

balance-tlb (5)@H_502_15@

balance-alb (6)@H_502_15@

--------------------------------------------------------------@H_502_15@

@H_502_15@

3)修改bond0网卡配置

修改下面表格中标红的内容@H_502_15@

---------------------------------------------------------------@H_502_15@

cd /etc/sysconfig/network-scripts@H_502_15@

[root@XACR-aliware04 network-scripts]# vimifcfg-bond-bond0@H_502_15@

DEVICE=bond0@H_502_15@

BONDING_OPTS=mode=active-backup@H_502_15@

TYPE=Bond@H_502_15@

BONDING_MASTER=yes@H_502_15@

BOOTPROTO=static ---将原来的dhcp 改成static@H_502_15@

DEFROUTE=yes@H_502_15@

PEERDNS=yes@H_502_15@

PEERROUTES=yes@H_502_15@

UUID=f4146d29-d694-4f13-ae59-56f940c7d120@H_502_15@

ONBOOT=yes@H_502_15@

IPADDR=192.168.80.7 ---配置分配给服务器的IP地址@H_502_15@

PREFIX=24 --配置子网掩码@H_502_15@

GATEWAY=192.168.80.1 ---配置网关@H_502_15@

@H_502_15@

保存并退出@H_502_15@

---------------------------------------------------------------@H_502_15@

4)重启网络

systemctl restart network �C重启网络服务@H_502_15@

cat /proc/net/bonding/bond0 ---查看bond0接口的相关信息@H_502_15@

----------------------------------------------------------------@H_502_15@

[root@XACR-aliware04 network-scripts]# cat /proc/net/bonding/bond0@H_502_15@
