环境:RHEL 6.5 注意:此处的机器环境是3网卡,我用eth0连ssh的,但是一直掉... 需要关闭NetworkManager,并将其设置为开机不启动(这个玩意儿真烦) 1. 创建bond0文件: vim /etc/sysconfig/network-scripts/ifcfg-bond0 DEVICE=bond0 ONBOOT=yes BOOTPROTO=static TYPE=Ethernet IPADDR=192.168.115.50 NETMASK=255.255.255.0 2. 修改网卡配置: vim /etc/sysconfig/network-scripts/ifcfg-eth1 DEVICE=eth1 ONBOOT=yes BOOTPROTO=none MASTER=bond0 SLAVE=yes USERCTL=no vim /etc/sysconfig/network-scripts/ifcfg-eth2 DEVICE=eth2 ONBOOT=yes BOOTPROTO=none MASTER=bond0 SLAVE=yes USERCTL=no 3. 加载bond模块,在配置文件末尾添加参数 vim /etc/modprobe.d/dist.conf alias bond0 bonding options bond0 mode=0 miimon=100 解析: mode 0表示为负载均衡模式,两块网卡都工作 mode 1表示冗余模式,一块是工作,一块冗余 miimon表示系统检查间隔时间,单位是ms, 例如:每100ms检查一次,当发现一条线路不通,就转入另一条 4. 将bond0设置为开机自动加载 vim /etc/rc.local ifenslave bond0 eth1 eth2 5. reboot ,之后使用ifconfig查看bond0和eht1,eth2两块网卡的MAC地址是否相同 注意不管bond 0 还是bond 1,都是三者相同,因为在交换机的时候需要识别MAC然后发送到对应的MAC上,不相同是不对的, 假如不相同,回去检查NetworkManager是不是关了 来个标准的: 注意 [root@oratest0 ~]# ifconfig bond0 Link encap:EthernetHWaddr00:0C:29:44:52:23 inet addr:192.168.115.50Bcast:192.168.115.255Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe44:5223/64Scope:Link UP BROADCAST RUNNING MASTER MULTICAST MTU:1500Metric:1 RX packets:878 errors:0 dropped:0 overruns:0 frame:0 TX packets:349 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:81301(79.3KiB) TX bytes:58143(56.7KiB) eth0 Link encap:EthernetHWaddr00:0C:29:44:52:19 inet addr:192.168.115.40Bcast:192.168.115.255Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe44:5219/64Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500Metric:1 RX packets:170 errors:0 dropped:0 overruns:0 frame:0 TX packets:11 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:15663(15.2KiB) TX bytes:746(746.0 b) eth1 Link encap:EthernetHWaddr00:0C:29:44:52:23 UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500Metric:1 RX packets:702 errors:0 dropped:0 overruns:0 frame:0 TX packets:175 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:65260(63.7KiB) TX bytes:27907(27.2KiB) eth2 Link encap:EthernetHWaddr00:0C:29:44:52:23 UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500Metric:1 RX packets:176 errors:0 dropped:0 overruns:0 frame:0 TX packets:174 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:16041(15.6KiB) TX bytes:30236(29.5KiB) lo Link encap:LocalLoopback inet addr:127.0.0.1Mask:255.0.0.0 inet6 addr:::1/128Scope:Host UP LOOPBACK RUNNING MTU:16436Metric:1 RX packets:10 errors:0 dropped:0 overruns:0 frame:0 TX packets:10 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:840(840.0 b) TX bytes:840(840.0 b) 6. 查看bond状态,能实时查看两块网卡的工作状态 cat /proc/net/bonding/bond0 (责任编辑：IT) |
