在linuxredhat下雙網(wǎng)卡負(fù)載均衡lacp

1、() linux If己置#cat /boot/config-kernel-version |grep -i bondingCONFIG_BONDING=m返回CONFIG_BONDING=m支持，否則需要編譯內(nèi)核使它支持 bonding也可以用：查看一下內(nèi)核是否已經(jīng)支持bonding : modinfo bonding第一步：創(chuàng)建一個(gè)ifcfg-bondX# touch /etc/sysconfig/network-scripts/ifcfg-bond0新建一個(gè) bond0 再己置文件# cat /etc/sysconfig/network-scripts/ifcfg-bond0DEVICE

2、=bond0BOOTPROTO=staticIPADDR=1.1.1.2NETMASK=255.255.255.0BROADCAST=1.1.1.255NETWORK=1.1.1.0GATEWAY=1.1.1.1ONBOOT=yesTYPE=Ethernet編輯ifcfg-bond0如上第二步：修改 /etc/sysconfig/network-scripts/ifcfg-ethX這個(gè)實(shí)驗(yàn)中把網(wǎng)卡 1和2綁定，修改/etc/sysconfig/network-scripts/ifcfg-ethX相應(yīng)網(wǎng)卡配置 如下：# cat /etc/sysconfig/network-scripts/ifc

3、fg-eth1TYPE=EthernetDEVICE=eth1HWADDR=00:d0:f8:40:f1:a0 網(wǎng)卡 1macBOOTPROTO=noneONBOOT=yesUSERCTL=noMASTER=bond0SLAVE=yes# cat /etc/sysconfig/network-scripts/ifcfg-eth2TYPE=EthernetDEVICE=eth2HWADDR=00:d0:f8:00:0c:0c 網(wǎng)卡 2macBOOTPROTO=noneONBOOT=yesUSERCTL=noMASTER=bond0SLAVE=yes第三步： 配置/etc/modprobe.con

4、f ，添加 alias bond0 bonding# cat /etc/modprobe.confalias eth0 e100alias snd-card-0 snd-intel8x0options snd-card-0 index=0options snd-intel8x0 index=0remove snd-intel8x0 /usr/sbin/alsactl store 0 >/dev/null 2>&1 | :; ; /sbin/modprobe -r-ignore-remove snd-intel8x0alias eth1 8139toooptions 3c50

5、1 irq=3alias eth2 tulip上面是三網(wǎng)卡本身的配置如果要綁定和做lacp只要再加上下面兩條配置alias bond0 bonding綁定options bond0 miimon=100 mode=4mode=4 是 lacp第四步：配置/etc/rc.d/rc.local ,添加需要綁定的網(wǎng)卡# cat /etc/rc.d/rc.localtouch /var/lock/subsys/local配置本身就有這條命令ifenslave bond0 eth1 eth2這條命令是添加需要綁定的網(wǎng)卡1和2到這里就完成bonding的配置了可以查看一下第五步：重啟網(wǎng)絡(luò)服務(wù)和重啟pc#s

6、ervice network restart重啟網(wǎng)絡(luò)服務(wù)# shutdown -r now重啟 pc重啟后可以查看 bonding情況：網(wǎng)卡1和2都綁定上了，模式為 802.3ad# cat /proc/net/bonding/bond0Ethernet Channel Bonding Driver: v3.0.3 (March 23, 2006)Bonding Mode: IEEE 802.3ad Dynamic link aggregationTransmit Hash Policy: layer2 (0)MII Status: upMII Polling Interval (ms): 1
