@文心快码nginx request failed with status code 502 文心快码 HTTP状态码502代表“Bad Gateway”,意味着服务器作为网关或代理,从上游服务器收到无效响应。在使用Nginx作为反向代理时,遇到502错误通常意味着Nginx无法从上游服务器(如应用服务器)获取有效响应。下面我将根据提供的提示,分点解答你的问题: 1.
nginx的502问题 1.配置错误 因为nginx找不到php-fpm了或者socket文件权限不对,所以报错,一般是fastcgi_pass后面的路径配置不当,后面可以是socket或者是ip:port,从php5.4版本之后如果使用socket方式,默认权限给的比较低,所以需要把监听权限改为777,对应配置为 listen.mode=0777 2.资源耗尽 lnmp架构在处理php时,nginx...
接口/user/autch/check出现no live upsteams,即报出502错误。 3、业务nginx查询接口xxxx/container日志情况: 接口xxxx/container请求频繁(相对历史),http code=499,即service服务处理超时,接入层直接断开请求了。 初步定位: 由于接口接口xxxx/container大量请求超时,可能导致接入层nginx会剔除业务nginx服务,然后接口/user...

If NGINX can’t access the socket for a particular pool, you can determine which worker pool is involved in the issue by checking which socket is named in the NGINX error log entry. For example, if PHP-FPM had failed to start themypoolworker pool, NGINX would return a 502 and its err...
If PHP-FPM's timeout—which is set in the pool configuration's request_terminate_timeout directive (and defaults to 20 seconds)—is less than NGINX's timeout (which defaults to 60 seconds), NGINX will respond with a 502 error. The NGINX error log shown below indicates that its upstream...
ensure that any request message it forwards does contain an appropriate Host header field that identifies the service being requested by the proxy. All Internet-based HTTP/1.1 servers MUST respond with a 400 (Bad Request) status code to any HTTP/1.1 request message which lacks a Host header ...
