IP：192.168.1.10
#yum -yinstall pcre-develzlib-devel bzip2-devel kernel-developenssl-devel popt-develzlib-devel
#tar zxfkeepalived-1.2.13.tar.gz解压源码包
#cd keepalived-1.2.13
#./configure--prefix=/ --with-kernel-dir=/usr/src/kernels/2.6.32-431.e16.x86_64
#make&& make install
#chkconfig--add keepalived添加为系统服务
#chkconfigkeepalivedon设置为开机自启动
#cd /etc/keeplived/
#cpkeepalived.conf keepalived.conf.bak备份一份以防万一
#vim keepalived.conf编辑主配置文件

#tarzxfhaproxy-1.4.24.tar.gz使用源码编译安装
#cdhaproxy-1.4.24
#make TARGET=linux26 64位系统
#make install
#mkdir/etc/haproxy 创建配置文件目录
#cpexamples/haproxy.cfg /etc/haproxy/ 将haproxy.cfg文件复制到配置文件目录
#scp root@192.168.1.10:/etc/haproxy/haproxy.cfg/etc/haproxy/haproxy/
从主复制到从一份此处不用修改
#cp /usr/src/haproxy-1.4.24/examples/haproxy.init/etc/init.d/haproxy
#ln -s/usr/local/sbin/haproxy/usr/sbin/haproxy
#chmod +x/etc/init.d/haproxy给一个执行权限
