Haproxy 配置文件中 'listen' cannot handle unexpected argument 报错信息

备注：当killall haproxy启动服务后发现配置文件还没有生效，就需要删除pidfile(目录：/var/run/haproxy.pid) 文件就,然后可以启动服务了。

启动haproxy 命令 /usr/local/haproxy/sbin/haproxy -f /usr/local/haproxy/haproxy.cfg

如果发现如下错误：

将上面 listen 后面的内容改为：

listen payserver

  bind 0.0.0.0:80

就可以解决语法错误，让haproxy正常运行
