[admin@node5 ~]$ tar xf haproxy-1.8.3.tar.gz
[admin@node5 ~]$ cd haproxy-1.8.3
[admin@node5 haproxy-1.8.3]$ sudo make TARGET=linux2628 PREFIX=/application/haproxy && make install PREFIX=/usr/local/haproxy （ 要确保application目录，admin用户有写入权限）
2）找到配置文件和启动脚本
[admin@node5 examples]$ pwd
/home/admin/haproxy-1.8.3/examples
[admin@node5 examples]$ sudo vim haproxy.init （更改里面的）
BIN=/application/haproxy/sbin/$BASENAME （这个更改在haproxy安装的目录） ---------------然后如果通过saltstack管理，就需要把这个haproxy.init启动脚本放到saltstack指定目录
