HAProxy配置TCP转发+监控页面

#配置文件
# cat /usr/local/haproxy/2.7.0/conf/haproxy.cfg

#     如何解决该问题呢。在服务器资源（内存、CPU）还未满负荷情况下，增加Haproxy代理该服务的连接数限制即可。最常用的连接数配置为maxconn
#
#　　 该配置中，在global、defaults、listen、server四个位置均有maxconn参数信息，其中：
#
#　　 global段中的maxconn:  设置整个haproxy进程的最大连接数
#
#　　 default段中的maxconn:  设置所有代理段的默认最大连接数
#
#　　 listen段中的maxconn:  设置该代理段的最大连接数
#
#　　 server中的maxconn:  设置该后台服务的最大连接数
