多 bonding 使用不同 mode 方法
环境,
多网卡, 多 bond 设备, 需要使用不同的工作方式, 如下:
eth0 eth1 -> bond0 -> mode 0 ( active-backup )
eth2, eth3 -> bond1 -> mode 1 (balance-rr)
参考:
[root@hh-yun-puppet-129021 kickstarts]# yum install -y kernel-doc
[root@hh-yun-puppet-129021 kickstarts]# rpm -ql kernel-doc | grep bonding.txt
/usr/share/doc/kernel-doc-2.6.32/Documentation/networking/bonding.txt
其中该文档描述
/etc/modprobe.d/bond.conf 需要具有下面的配置
<pre class="plain" name="code">alias bond0 bonding options bond0 -o bond0 mode=balance-rr miimon=100 alias bond1 bonding options bond1 -o bond1 mode=balance-alb miimon=50
但上述文档只能够针对 centos 5 或之前版本, 而文档也没有更新 centos 6, 7 下的方法
而 centos 6,7 将不可以使用 -o 参数进行参数定义, 另外, 假如把配置, 参数都写入 /etc/modprobe.d/bond.conf 如
alias bond0 bonding options bond0 mode=balance-rr miimon=100 alias bond1 bonding options bond1 mode=balance-alb miimon=50
看上去 bond0, bond1 可以启动, 但从内核参数显示, 上述的设备只会使用相同的工作模式, 不满足不同 bond 设备使用不同模式方法
参考:
[root@hh-yun-compute-130026 ~]# grep Mode /proc/net/bonding/bond0 Bonding Mode: load balancing (round-robin) [root@hh-yun-compute-130026 ~]# grep Mode /proc/net/bonding/bond1 Bonding Mode: load balancing (round-robin)
centos 6, 7 上正确配置方法:
/etc/modprobe.d/bond.conf
alias bond0 bonding alias bond1 bonding
/etc/sysconfig/network-scripts/ifcfg-bond0
BONDING_OPTS='mode=1 miimon=100'
/etc/sysconfig/network-scripts/ifcfg-bond1
BONDING_OPTS='mode=0 miimon=100'
另: 注意, centos 7 下, 假如关闭 ipv6 模块使用, 那么 bond 模块也是无法正常使用的.
而 centos 7 已推荐使用 teamd 进行 bond 配置
teamd 与 bond 实现相同功能, 但新增不少新特性, 比较灵活, 相关信息自己看官方文旦
测试配置方法
[root@node147 network-scripts]# cat ifcfg-eth0
DEVICE="eth0"
DEVICETYPE=TeamPort
ONBOOT=yes
TEAM_MASTER=team0
TEAM_PORT_CONFIG='{"prio": 100}'
[root@node147 network-scripts]# cat ifcfg-eth1
DEVICE=eth1
DEVICETYPE=TeamPort
ONBOOT=yes
TEAM_MASTER=team0
TEAM_PORT_CONFIG='{"prio": 100}'
[root@node147 network-scripts]# cat ifcfg-eth2
DEVICE="eth2"
DEVICETYPE=TeamPort
ONBOOT=yes
TEAM_MASTER=team1
TEAM_PORT_CONFIG='{"prio": 100}'
[root@node147 network-scripts]# cat ifcfg-eth3
DEVICE="eth3"
DEVICETYPE=TeamPort
ONBOOT=yes
TEAM_MASTER=team1
TEAM_PORT_CONFIG='{"prio": 100}'
team 配置与 mode 配置
[root@node147 network-scripts]# cat ifcfg-team0
DEVICE=team0
DEVICETYPE=Team
ONBOOT=yes
BOOTPROTO=none
IPADDR=192.168.48.147
GATEWAY=192.168.48.1
PREFIX=24
TEAM_CONFIG='{"runner": {"name": "activebackup"}, "link_watch": {"name": "ethtool"}}'
[root@node147 network-scripts]# cat ifcfg-team1
DEVICE=team1
DEVICETYPE=Team
ONBOOT=yes
BOOTPROTO=none
IPADDR=10.0.0.147
PREFIX=24
TEAM_CONFIG='{"runner": {"name": "loadbalance"}, "link_watch": {"name": "ethtool"}}'
