RHEL雙網卡綁定

RHEL雙網卡綁定 新增綁定網卡檔案：vi /etc/sysconfig/network-scripts/ifcfg-bond0DEVICE=bond0ONBOOT=yesTYPE=EthernetBOOTPROTO=staticIPADDR=192.168.56.101NETMASK=255.255.255.0#GATEWAY=192.168.56.101#BROADCAST=10.250.7.255 修改現有網卡配置：cp /etc/sysconfig/network-scripts/ifcfg-eth0 ~/ifcfg-eth0.bakcp /etc/sysconfig/network-scripts/ifcfg-eth1 ~/ifcfg-eth1.bak vi /etc/sysconfig/network-scripts/ifcfg-eth0DEVICE=eth0BOOTPROTO=noneONBOOT=yesUSERCTL=noMASTER=bond0SLAVE=yes vi /etc/sysconfig/network-scripts/ifcfg-eth0DEVICE=eth1BOOTPROTO=noneONBOOT=yesUSERCTL=noMASTER=bond0SLAVE=yes 增加系統載入參數：vi /etc/modprobe.confalias bond0 bondingoptions bond0 miimon=100 mode=1mode=0 load balancing  (round-robin)；mode=1 fault-tolerance (active-backup)提供冗餘功能。 增加系統啟動載入參數：vi /etc/rc.d/rc.localifenslave bond0 eth0 eth1#route add -net 172.31.3.254 netmask 255.255.255.0 bond0 啟動網卡：ifconfig  bond0 192.168.56.101 up 重啟伺服器：reboot 檢查網卡綁定後狀態：cat /proc/net/bonding/bond0 ifconfig-EOF-
