LVS依赖于ipvsadm来进行配置，所以我们首先先安装ipvsadm
ipvsadm安装有两种方式 YUM安装 源码安装
1 YUM安装
yum -y install ipvsadm
/etc/init.d/ipvsadm start
2源码安装
ln -s /usr/src/kernels/2.6.32-696.1.1.el6.x86_64 /usr/src/linux
如果kernels里没有内核文件yum安装
yum install kernel-devel -y
解决依赖关系
yum -y install popt-static
tar xf ipvsadm-1.24.tar.gz
cd /tools/ipvsadm-1.24
make && make install
/sbin/ipvsadm #把lvs加载如内核
lsmod |grep ip_vs
如果出现内容表示安装成功
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
启动lvs
/etc/init.d/ipvsadm save
/etc/init.d/ipvsadm restart
chkconfig --add ipvsadm
chkconfig ipvsadm on
