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2 cp p1p1 p1p2 网卡的初始配置到tmp 目录下，进行备份。--------------------------------------------------------------[root@XACR-aliware04 ~]# cd /etc/sysconfig/network-scripts/[root@XACR-aliware04 network-scripts]# cp ifcfg-p1p1 /tmp[root@XACR-aliware04 network-scripts]# cp ifcfg-p1p2 /tmp--------------------------------------------------------------2) 使用nmcli命令配置bond生成bond配置
--------------------------------------------------------------
nmcli con add type bond ifname bond0 mode 1nmcli con add type bond-slave ifname p1p1 master bond0nmcli con add type bond-slave ifname p1p2 master bond0
注：p1p1 p1p2 为物理网卡的名字
bond的mode如下：balance-rr (0) --轮询模式（bond默认的模式）active-backup (1) --主备模式（常用）balance-xor (2) broadcast (3) 802.3ad (4) --聚合模式balance-tlb (5) balance-alb (6)--------------------------------------------------------------

3) 修改bond0网卡配置

修改下面表格中标红的内容---------------------------------------------------------------cd /etc/sysconfig/network-scripts[root@XACR-aliware04 network-scripts]# vim ifcfg-bond-bond0DEVICE=bond0BONDING_OPTS=mode=active-backupTYPE=BondBONDING_MASTER=yesBOOTPROTO=static ---将原来的dhcp 改成staticDEFROUTE=yesPEERDNS=yesPEERROUTES=yesIPV4_FAILURE_FATAL=noNAME=bond-bond0UUID=f4146d29-d694-4f13-ae59-56f940c7d120ONBOOT=yesIPADDR=192.168.80.7 ---配置分配给服务器的IP地址PREFIX=24 --配置子网掩码GATEWAY=192.168.80.1 ---配置网关 保存并退出---------------------------------------------------------------

4) 重启网络

systemctl restart network –重启网络服务cat /proc/net/bonding/bond0 ---查看bond0接口的相关信息----------------------------------------------------------------[root@XACR-aliware04 network-scripts]# cat /proc/net/bonding/bond0Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011)Bonding Mode: fault-tolerance (active-backup)Primary Slave: NoneCurrently Active Slave: p1p2MII Status: upMII Polling Interval (ms): 100Up Delay (ms): 0Down Delay (ms): 0 Slave Interface: p1p1MII Status: upSpeed: 10000 MbpsDuplex: fullLink Failure Count: 2Permanent HW addr: f4:e9:d4:9a:f1:a0Slave queue ID: 0 Slave Interface: p1p2MII Status: upSpeed: 10000 MbpsDuplex: fullLink Failure Count: 2Permanent HW addr: f4:e9:d4:9a:f1:a2Slave queue ID: 0-------------------------------------------------------------------到此就完成bond配置了---
