1.在调度器上面：

1.1安装软件包haproxy

[[email protected] ~]# yum -y install gcc

[[email protected] ~]# yum -y install pcrepcre-devel

[[email protected] haproxy-1.4.24]# tar -zxvfhaproxy-1.4.24.tar.gz

[[email protected] haproxy-1.4.24]# cdhaproxy-1.4.24

[[email protected] haproxy-1.4.24]# uname -r

2.6.32-431.el6.x86_64

[[email protected] haproxy-1.4.24]# cat README

[[email protected]]# make TARGET=linux2632 USE_PCRE=1 PREFIX=/usr/local/haproxy install

[[email protected] haproxy-1.4.24]# cd examples/

[[email protected] examples]# cp haproxy.init/etc/init.d/haproxy

[[email protected] examples]# chmod +x/etc/init.d/haproxy

[[email protected] examples]# mkdir /etc/haproxy

[[email protected] examples]# cp haproxy.cfg/etc/haproxy/

[[email protected] examples]# ln -s/usr/local/haproxy/sbin/haproxy /usr/sbin/
