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
#执行ipvsadm命令加载
ipvsadm
#查看结果
[root@shell ~]# lsmod |grep ip_vs
ip_vs_rr 1420 1
ip_vs 115643 3 ip_vs_rr
libcrc32c 1246 1 ip_vs
ipv6 321422 137 ip_vs
keepalived安装部署：
yum install openssl openssl-devel –y
yum install popt* -y
wget http://www.keepalived.org/software/keepalived-1.1.19.tar.gz
tar zxf keepalived-1.1.19.tar.gz
cd keepalived-1.1.19
#./configure && make && make install
./configure --sysconf=/etc && make && make install
/bin/cp /usr/local/sbin/keepalived /usr/sbin/
