#失败重试
#fail_timeout:时间段内计数失败次数
#max_fails：需要fail_timeout时间段统计的失败次数
#两个参数说明：在5秒时间段时，处理请求失败2次，则标记为不可用状态
#重要的一点说明：fail_timeout还有一个作用，标记为不可用状态的节点，在等待5秒后，
#会被尝试分配一个请求过来以便检测是否恢复可用状态!!!
#默认使用轮询节点分配请求
#max_fails默认=1，fail_timeout默认=10s;

#限流 通过模块 ngx_http_limit_conn_module
#$server_name=server_name 这种是对服务器端进行限流 zone 是字典存储缓存空间 perserver 为10M大小
#limit_conn perserver 2; #只允许2个并发请求到后端 缺陷如果有个客户端(黑客)一次发送1万个请求导致 其他客户端无法请求
#limit_conn_zone $server_name zone=perserver:10m;
#对客户端进行限流 用binary_remote_addr
#limit_conn_zone $binary_remote_addr zone=perserver:10m; 这种方式 有一个缺陷
#如果 是1万个客户端每个客户端发送一个请求 就是同时有1万个请求 到达服务端，此时可能存在宕机风险所以要采用平滑限流
#对服务端限流
#limit_conn_zone $server_name zone=perserver:10m;
#对客户端限流
#limit_conn_zone $binary_remote_addr zone=perserver:10m;
#平滑限流 使用的 是limit_req_zone 增加了rate=2r/s; 解释 1秒处理2个请求 如果 同时有个10个请求
#那么就是1000毫秒除以10个请求 就是100毫秒 处理1个请求 将时间分片处理请求
