双网卡配置 bond mode4 配置

1 # cat /etc/redhat-release
2 CentOS Linux release 7.6.1810 (Core)

yum search ifconfig
yum install net-tools.x86_64

查看网线是否插入

# cat /sys/class/net/ens3f0/carrier
1
# cat /sys/class/net/ens3f1/carrier
1

关闭 NetworkManager 服务

//网卡文件配置正常、bond0文件配置也正常；重启网络服务之后，bond0起来了，ping自己IP通，但是到网关不通，就是因为NetworkManager服务没有关闭，关闭之后重启网络服务，网络就通了。

1 systemctl status NetworkManager.service
2 systemctl stop NetworkManager.service
3 systemctl disable NetworkManager.service

内核加载 bonding

1 modprobe --first-time bonding

1 # lsmod | grep bonding
2 bonding               152656  0

创建配置文件 ifcfg-bond0

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

 1 DEVICE=bond0
 2 TYPE=Bond
 3 IPADDR=192.168.2.11
 4 NETMASK=255.255.255.0
 5 GATEWAY=192.168.2.1
 6 DNS1=114.114.114.114
 7 USERCTL=no
 8 BOOTPROTO=none
 9 ONBOOT=yes
10 BONDING_MASTER=yes
11 BONDING_OPTS="miimon=100 mode=4 xmit_hash_policy=layer3+4"

如果bond0接口已经配置，不再需要配置

1 vim /etc/modprobe.d/bond.conf
2 alias bond0 bonding
3 options bond0 miimon=100 mode=4 xmit_hash_policy=layer3+4

备份网卡配置文件

1 cd /etc/sysconfig/network-scripts
2 cp ifcfg-ens3f0 ifcfg-ens3f0_backup
3 cp ifcfg-ens3f1 ifcfg-ens3f1_backup

ens3f0

1 vim /etc/sysconfig/network-scripts/ifcfg-ens3f0

 2 PROXY_METHOD=none
 3 BROWSER_ONLY=no
 4 BOOTPROTO=none
 5 DEFROUTE=yes
 6 IPV4_FAILURE_FATAL=no
 7 IPV6INIT=yes
 8 IPV6_AUTOCONF=yes
 9 IPV6_DEFROUTE=yes
10 IPV6_FAILURE_FATAL=no
11 IPV6_ADDR_GEN_MODE=stable-privacy
12 NAME=ens3f0
13 UUID=39aa32a1-acb3-4cd3-a806-be5c041a2310
14 DEVICE=ens3f0
15 ONBOOT=yes
16 MASTER=bond0
17 SLAVE=yes

ens3f1

1 vim /etc/sysconfig/network-scripts/ifcfg-ens3f1

 1 TYPE=Ethernet
 2 #PROXY_METHOD=none
 3 #BROWSER_ONLY=no
 4 BOOTPROTO=none
 5 #DEFROUTE=yes
 6 #IPV4_FAILURE_FATAL=no
 7 #IPV6INIT=yes
 8 #IPV6_AUTOCONF=yes
 9 #IPV6_DEFROUTE=yes
10 #IPV6_FAILURE_FATAL=no
11 #IPV6_ADDR_GEN_MODE=stable-privacy
12 NAME=ens3f1
13 #UUID=4b5c8908-3e83-40b2-a9db-d0713135f4c2
14 DEVICE=ens3f1
15 ONBOOT=yes
16 MASTER=bond0
17 SLAVE=yes
18 NM_CONTROLLED=no//表示该接口将通过该配置文件进行设置，而不是通过网络管理器进行管理
19 USERCTL=no//是否允许非root用户控制该设备，设置为no，只能用root用户更改

注释掉的行可以不用写

重启网络服务

1 systemctl restart network

1 # ifconfig
2 bond0: flags=5187<UP,BROADCAST,RUNNING,MASTER,MULTICAST>  mtu 1500
3         inet 192.168.2.11  netmask 255.255.255.0  broadcast 192.168.2.255
