cp /usr/local/haproxy/sbin/haproxy /etc/init.d/
/usr/local/haproxy/sbin/haproxy -f /usr/local/haproxy/conf/haproxy.cfg
####################HAProxy配置中分成五部分内容，当然这些组件不是必选的，可以根据需要选择部分作为配置。
#global ：参数是进程级的，通常和操作系统（OS）相关。这些参数一般只设置一次，如果配置无误，就不需要再次配置进行修改
#defaults：配置默认参数的，这些参数可以被利用配置到frontend，backend，listen组件
#frontend：接收请求的前端虚拟节点，Frontend可以根据规则直接指定具体使用后端的 backend(可动态选择)。
#backend ：后端服务集群的配置，是真实的服务器，一个Backend对应一个或者多个实体服务器。
#listen ：Frontend和Backend的组合体。

- ha_check.sh
- 用脚本的时候，source 一下，确保脚本是正确可以执行的，另外${ps -C haproxy --no-header |wc -l} 如果执行不了，试着把{}换成 : ``
- 需要多测试几次这个脚本，特别是sleep语句的位置，是在if内外？
- 给ha_check.sh脚本加777权限：chmod 777 ha_check.sh
#!/bin/bash
if [ ${ps -C haproxy --no-header |wc -l} -eq 0 ]; then
/usr/local/haproxy/sbin/haproxy -f /usr/local/haproxy/conf/haproxy.cfg
