lvs 安装部署：
1、查看内核模块是否支持
lsmod | grep ip_vs #发现没有
2、安装
wget http://www.linuxvirtualserver.org/software/kernel-2.6/ipvsadm-1.26.tar.gz
tar zxf ipvsadm-1.26.tar.gz
cd ipvsadm-1.26
yum -y install kernel-devel
ln -s /usr/src/kernels/2.6.32-431.17.1.el6.x86_64/ /usr/src/linux
make && make install
3、报错信息解决
报错：
make[1]: *** [libipvs.o] Error 1
make[1]: Leaving directory `/mnt/tools/ipvsadm-1.26/libipvs’
make: *** [libs] Error 2
解决:
yum -y install libnl* popt*
4、加载 ip_vs 模块
