linux下LVS集群搭建（原创手写有截图）

Centos 5.8 lvs 配置

一、安装前的准备

 安装所需包

Yum install gcc openssl openssl-devel ipvsadmmodcluster oddjob oddjob-devel oddjob-libs

piranha system-cong-cluster php php-cli php-common http

 创建虚拟 IP

在主调度机上设置虚拟 IP：

 cp /etc/syscong/network-scripts/ifcfg-eth0 /etc/syscong/network-scripts/ifcfg-eth0:0

 net.ipv4.ip_forward = 1 启用转发

在应用服务器上执行

echo "1">/proc/sys/net/ipv4/conf/lo/arp_ignore

echo "2">/proc/sys/net/ipv4/conf/lo/arp_announce

echo "1" >/proc/sys/net/ipv4/conf/all/arp_ignore

echo "2">/proc/sys/net/ipv4/conf/all/arp_announce

sysctl –p 使之生效

二、通过 piranha 配置 ipvsadm（LVS）LVSroute1 为主调度机

piranha-passwd
