Error prompt Cause Analysis: To solve these two problems is a need for comprehensive thinking, in general Nginx 502 Bad Gateway and php-fpm.conf settings,and the Nginx 504 Gateway time-out is related to the nginx.conf setting.Php

Situation One solution:The default fastcgi process response buffer is 8K, we can set a larger, in nginx.conf, join: Fastcgi_buffers 8 128kThis indicates that the fastcgi buffer is set to a size of 8 128k in space. 3Situation one solution (improvement):After the above method is modified, if the problem still occurs, we can continue to modify the Nginx timeout parameter, the parameter is a bit larger, such as set to 60 seconds:Send_timeout 60;After t

Http://www.linuxyw.com/470.html My operation and maintenance system is developed with Python+django, running in NGINX+UWSGI environment System has part of the function is to update the game program, etc., if the file more or larger time, may need to wait longer, if nginx use the default configuration, generally 60 seconds will appear timeout

after which the worker process will be terminated Shocould be used when 'max _ execution_time 'ini option does not stop script execution for some reason '0s' means 'off' 0 s The default value is 0 seconds. that is to say, the PHP script will be executed continuously. in this way, when all php-cgi processes are stuck in the file_get_contents () function, this Nginx + PHP WebServer can no longer process new PHP requests.

Proxy Server Nginx Configuration This is the case The code is as follows Copy Code Server { listen server_name *.*; location/{ Proxy_pass http://192.168.0.100:8001; Proxy_set_header Host $host; Proxy_set_header X-forwarded-for $proxy _add_x_forwarded_for; Proxy_set_header X-real-ip $remote _addr; Proxy_redirect Default } } Normal access no problem, once running a long

this time, Nginx cannot transfer the PHP file to PHP-FPM processing, so the CPU will be reduced to very low (not to handle PHP, not to execute SQL), and the load will rise to very high (close and open children, nginx wait php-fpm), the network card traffic is also reduced to very low ( Nginx cannot generate data trans

buffer size. Third, Request_terminate_timeout If it's mostly in the case of post or database operations, rather than being common in static page operations, you can look at one of the php-fpm.conf settings: Request_terminate_timeout This value is Max_execution_time, which is the execution script time of the fast-cgi. 0s 0s to be closed, is to carry out indefinitely.

502 Bad Gateway error solutionThere are many causes of Nginx 502 errors because of problems with backend servers in proxy mode. These errors are not nginx problems, so you must find the cause from the backend! However, nginx has put all these errors on its own, which makes it highly questionable for

But be careful to calculate whether your memory is enough to support more processes, if the physical machine memory is not large enough, it is useless to increase the number of processes.2, some of the PHP program execution time than the Nginx wait
