1. 創建bond0文件:
#vim /etc/sysconfig/network/ifcfg-bond0 BOOTPROTO='static' BROADCAST='' IPADDR='192.168.74.141/24' NETMASK='255.255.255.0' NETWORK='' STARTMODE='auto' BONDING_MASTER='yes' BONDING_SLAVE0='eth0' BONDING_SLAVE1='eth1' BONDING_MODULE_OPTS='mode=1 miimon=100 fail_over_mac=1' ETHTOOL_OPTIONS='' MTU='' NAME='' REMOTE_IPADDR='' USERCONTROL='no'
解析說明:
mode 0表示為負載均衡模式,兩塊網卡都工作（需要交換機端口聚合,在SLES 12SP3上用此模式測試未通過）
mode 1表示冗余模式,一塊是工作,一塊冗余
miimon表示系統檢查間隔時間,單位是ms,
fail_over_mac=1 在Vmware里測試時使用,否則Ping會斷開
例如:每100ms檢查一次,當發現一條線路不通,就轉入另一條
2. 修改網卡配置:
#vim /etc/sysconfig/network/ifcfg-eth0 BOOTPROTO='none' #配置bond時必需將static,dhcp改為none BROADCAST='' ETHTOOL_OPTIONS='' IPADDR='' #配置bond時必需將IP置空 MTU='' NAME='82545EM Gigabit Ethernet Controller (Copper)' NETWORK='' REMOTE_IPADDR='' STARTMODE='off' #配置bond時必需將auto改為off USERCONTROL='no' #vim /etc/sysconfig/network/ifcfg-eth1 BOOTPROTO='none' #配置bond時必需將static,dhcp改為none BROADCAST='' ETHTOOL_OPTIONS='' IPADDR='' #配置bond時必需將IP置空 MTU='' NAME='82545EM Gigabit Ethernet Controller (Copper)' NETWORK='' REMOTE_IPADDR='' STARTMODE='off' #配置bond時必需將auto改為off USERCONTROL='no'
3. 重啟網絡服務,或是重啟主機操作系統
#service network restart #shutdown -r 0
4. 查看狀態及測試
#ifconfig #可以看到bond0已經起來了 #cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011) Bonding Mode: fault-tolerance (active-backup) (fail_over_mac active) Primary Slave: None Currently Active Slave: eth0 MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 Slave Interface: eth0 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 3 Permanent HW addr: 00:0c:29:5f:57:a4 Slave queue ID: 0 Slave Interface: eth1 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 3 Permanent HW addr: 00:0c:29:5f:57:ae Slave queue ID: 0 #ifconfig eth0 down #ifconfig eth0 up #ifconfig eth1 down #ifconfig eth1 up
