Nginx配置max_fails fail_timeout 不起作用

1.默认配置时，http_404状态不被认为是失败的尝试。

2.location

location / {
            proxy_pass http://tomcatserver1;
            index  index.html index.htm;
            # proxy_next_upstream
            proxy_next_upstream error timeout invalid_header http_500 http_503 http_404; 
            proxy_connect_timeout 7s;
            proxy_read_timeout 7s;
            proxy_send_timeout 7s;
        }

3.配置nginx.conf文件 具体配置如下

 upstream report{                                                                                                                       
         server localhost1:18080 max_fails=10 fail_timeout=7s;                                                                                                            
         server localhost1:28080 max_fails=10 fail_timeout=7s;                                                                                                            
        server localhost2:18080 max_fails=10 fail_timeout=7s;                                                                                                             
        server localhost2:28080 max_fails=10 fail_timeout=7s;                                                                                                             
        #ip_hash;                                                                                                                              
    }
