nginx+tomcat 504 Gateway Time-out异常

应用是nginx+tomcat

根据这个错误,是因为tomcat没有及时回应nginx,导致错误.

先使用 fiddler 将页面的请求抓出来.

找到504的请求.然后查找原因.

因为这个请求时间比较长,只有90秒.

 

所以修改

proxy_connect_timeout   90;

proxy_send_timeout      90;

proxy_read_timeout      90;

 

修改成

proxy_connect_timeout   18000; ##修改成半个小时

proxy_send_timeout      18000;

proxy_read_timeout      18000;

 

 

附上，nginx配置文件实例
