1、1：编辑ifcfg-bond0[root@db2 ~]# cd /etc/sysconfig/network-scripts/[root@db2 network-scripts]# cat ifcfg-bond0DEVICE="bond0"BOOTPROTO=noneNM_CONTROLLED=noONBOOT=yesIPADDR=172.17.214.5NETMASK=255.255.255.0PREFIX=24DEFROUTE=yesGATEWAY=172.17.214.1TYPE=Ethernet
2、2：编辑ifcfg-eth1和ifcfg-eth2[root@db2 network-scripts]# cat ifcfg-eth1DEVICE=eth1BOOTPROTO=noneHWADDR=90:B1:1C:2F:C9:94NM_CONTROLLED=noONBOOT=yesTYPE=EthernetIPV6INIT=noUSERCTL=noMASTER=bond0SLAVE=yesYou have mail in /var/spool/mail/root[root@db2 network-scripts]# cat ifcfg-eth2DEVICE=eth2BOOTPROTO=noneHWADDR=90:B1:1C:2F:C9:96NM_CONTROLLED=noONBOOT=yesTYPE=EthernetIPV6INIT=noUSERCTL=noMASTER=bond0SLAVE=yes[root@db2 network-scripts]#
3、3：编辑/etc/modprobe.d/dist.conf[root@db1 network-scripts]# vi /etc/modprobe.d/dist.conf增加两行alias bond0 bondingoptions bond0 miimon=1000 mode=1
4、4：编辑/etc/rc.d/rc.local[root@db2 modprobe.d]# cd /etc/rc.d/[root@db2 rc.d]# vi rc.local增加一行：ifenslave bond0 eth1 eth2
5、5：关闭NetworkManager 并设置永久关闭[root@db1 network-scripts]# chkconfig NetworkManager off[root@db2 rc.d]# chkconfig --list | grep NetNetworkManager 0:off 1:off 2:off 3:off 4:off 5:off 6:off
6、6：重启服务器[root@db2 ~]# ifconfigbond0 Link encap:Ethernet HWaddr 90:B1:1C:2F:C9:94 inet addr:172.17.214.5 Bcast:172.17.214.255 Mask:255.255.255.0 inet6 addr: fe80::92b1:1cff:fe2f:c994/64 Scope:Link UP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1 RX packets:21232 errors:0 dropped:0 overruns:0 frame:0 TX packets:213 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1813036 (1.7 MiB) TX bytes:28462 (27.7 KiB)eth0 Link encap:Ethernet HWaddr 90:B1:1C:2F:C9:92 inet addr:10.10.10.2 Bcast:10.10.10.255 Mask:255.255.255.0 inet6 addr: fe80::92b1:1cff:fe2f:c992/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:7046 errors:0 dropped:0 overruns:0 frame:0 TX packets:25 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:495113 (483.5 KiB) TX bytes:4073 (3.9 KiB) Interrupt:34 Memory:c6000000-c6012800eth1 Link encap:Ethernet HWaddr 90:B1:1C:2F:C9:94 UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1 RX packets:10734 errors:0 dropped:0 overruns:0 frame:0 TX packets:213 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:916453 (894.9 KiB) TX bytes:28462 (27.7 KiB) Interrupt:44 Memory:c8000000-c8012800eth2 Link encap:Ethernet HWaddr 90:B1:1C:2F:C9:94 UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1 RX packets:10498 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:896583 (875.5 KiB) TX bytes:0 (0.0 b) Interrupt:35 Memory:ca000000-ca012800eth3 Link encap:Ethernet HWaddr 90:B1:1C:2F:C9:98 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Interrupt:46 Memory:cc000000-cc012800[root@db2 network-scripts]# cat /proc/net/bonding/bond0Ethernet Channel Bonding Driver: v3.6.0 (September 26, 2009)Bonding Mode: fault-tolerance (active-backup)Primary Slave: NoneCurrently Active Slave: eth1MII Status: upMII Polling Interval (ms): 1000Up Delay (ms): 0Down Delay (ms): 0Slave Interface: eth1MII Status: upSpeed: 1000 MbpsDuplex: fullLink Failure Count: 0Permanent HW addr: 90:b1:1c:2f:c9:94Slave queue ID: 0Slave Interface: eth2MII Status: upSpeed: 1000 MbpsDuplex: fullLink Failure Count: 0Permanent HW addr: 90:b1:1c:2f:c9:96Slave queue ID: 0[root@db2 network-scripts]#双网卡绑定正常，跳网段连接正常
