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

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
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
