实验环境
[root@localhost ~]# cat /etc/redhat-release CentOSLinux release 7.2.1511(Core) [root@localhost ~]# uname -r 3.10.0-327.el7.x86_64
linux服务器 eno33554960 与 eno50332184 两张网卡配置 bond 步骤(如果要配置多个bond0,1…按照这个流程重复操作即可)参考
查看网卡信息
[root@localhost ~]# ip addr 1: lo:<LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eno16777736:<BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:0c:29:07:2c:86 brd ff:ff:ff:ff:ff:ff inet 192.168.92.11/24 brd 192.168.92.255 scope global eno16777736 valid_lft forever preferred_lft forever inet6 fe80::20c:29ff:fe07:2c86/64 scope link valid_lft forever preferred_lft forever 3: eno33554960:<BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:0c:29:07:2c:90 brd ff:ff:ff:ff:ff:ff 4: eno50332184:<BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:0c:29:07:2c:9a brd ff:ff:ff:ff:ff:ff
1 备份网卡配置文件
[root@localhost ~]# cd /etc/sysconfig/network-scripts/ [root@localhost network-scripts]# mkdir /tmp/net_bak [root@localhost network-scripts]# cp ifcfg-*/tmp/net_bak/ [root@localhost network-scripts]# ls /tmp/net_bak/ ifcfg-eno16777736 ifcfg-eno33554960 ifcfg-eno50332184 ifcfg-eno67109408 ifcfg-eno83886632 ifcfg-lo
2 使用nmcli命令配置bond
# 生成bond配置文件 [root@localhost network-scripts]# nmcli connection add type bond ifname bond0 mode 1 # 将网卡`eno33554960`与`eno50332184`绑定到bond0 [root@localhost network-scripts]# nmcli connection add type bond-slave ifname eno33554960 master bond0 [root@localhost network-scripts]# nmcli connection add type bond-slave ifname eno50332184 master bond0 # 查看生成的配置文件 [root@localhost network-scripts]# ls ifcfg-bond-* ifcfg-bond-bond0 ifcfg-bond-slave-eno33554960 ifcfg-bond-slave-eno50332184
bond的mode如下:
3 修改bond0网卡配置
[root@localhost network-scripts]# vim ifcfg-bond-bond0 DEVICE=bond0 BONDING_OPTS=mode=active-backup TYPE=Bond BONDING_MASTER=yes BOOTPROTO=static====>将 dhcp 改为static DEFROUTE=yes PEERDNS=yes PEERROUTES=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_PEERDNS=yes IPV6_PEERROUTES=yes IPV6_FAILURE_FATAL=no NAME=bond-bond0 UUID=af2d6662-608c-4f5d-8018-1984cc3d87ef ONBOOT=yes IPADDR=192.168.92.20# 配置 IP 地址 PREFIX=24# 配置掩码 也可以使用 NETMASK=255.255.255.0 GATEWAY=192.168.92.2# 配置网关
Tips: 如果不想修改bond网络接口配置文件可以在第2步的第一条命令后加上 ip4 "ip地址" gw4 "网关地址"
nmcli connection add type bond ifname bond0 mode 1 ip4 192.168.92.20/24 gw4 192.168.92.2
4 重启网络,验证配置结果
1. 查看网卡信息
[root@localhost network-scripts]# ip addr show 1: lo:<LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever
2: eno16777736:<BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:0c:29:07:2c:86 brd ff:ff:ff:ff:ff:ff inet 192.168.92.11/24 brd 192.168.92.255 scope global eno16777736 valid_lft forever preferred_lft forever inet6 fe80::20c:29ff:fe07:2c86/64 scope link valid_lft forever preferred_lft forever
3: eno33554960:<BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master bond0 state UP qlen 1000 link/ether 00:0c:29:07:2c:90 brd ff:ff:ff:ff:ff:ff
4: eno50332184:<BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master bond0 state UP qlen 1000 link/ether 00:0c:29:07:2c:90 brd ff:ff:ff:ff:ff:ff
31: bond0:<BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP link/ether 00:0c:29:07:2c:90 brd ff:ff:ff:ff:ff:ff inet 192.168.92.20/24 brd 192.168.92.255 scope global bond0 valid_lft forever preferred_lft forever inet6 fe80::20c:29ff:fe07:2c90/64 scope link valid_lft forever preferred_lft forever
2. 查看bond信息
[root@localhost network-scripts]# cat /proc/net/bonding/bond0
EthernetChannelBondingDriver: v3.7.1(April27,2011)
BondingMode: fault-tolerance (active-backup)===> bond主备模式 PrimarySlave:None
CurrentlyActiveSlave: eno33554960 ===>当前激活的网卡eno33554960 MII Status: up MII PollingInterval(ms):100 UpDelay(ms):0 DownDelay(ms):0
SlaveInterface: eno33554960 ===> bond0 组内的网卡 MII Status: up Speed:1000Mbps Duplex: full LinkFailureCount:0 Permanent HW addr:00:0c:29:07:2c:90 Slave queue ID:0
SlaveInterface: eno50332184 ===> bond0 组内的网卡 MII Status: up Speed:1000Mbps Duplex: full LinkFailureCount:0 Permanent HW addr:00:0c:29:07:2c:9a Slave queue ID:0
5 删除 bond 设备
当我们需要删除bond设备的时候,该如何删除呢?请看下面操作
1.查看网络设备
[root@localhost ~]# ls /sys/class/net/ bond0 bond1 bonding_masters eno16777736 eno33554960 eno50332184 eno67109408 eno83886632 lo
2.删除bond网络设备
直接删除bond0,会提示无权限。
可以通过bonding_masters文件删除bond设备,但是bonding_masters文件是无法直接修改的。
[root@localhost ~]# echo -bond0 >/sys/class/net/bonding_masters
echo 后面的 ‘-’ 是删除设备,‘+’是增加设备
