在将代码部署到服务器后，遇到NGINX日志频繁报错'recv() failed (104: Connection reset by peer) while reading response header from upstream'。经过排查，问题并非由NGINX配置或PHP-FPM配置引起，而是由于安全规则中入口和出口端口设置不恰当。最终解决方案是调整安全策略，开放所有出口端口，从而消除该错误。

recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 127.0.0.1, server: 127.0.0.1, request: "GET /data.php?random=0YMkNeNyJhY3kQiOiJMrIiwiYdCI6M0TYxODNc2MDYk4MjkyMNX0_&callback=jQuery35104466580732208365_1618760682879&_=1618760682880 HTTP/1.1", upstream: "fastcgi://unix:/tmp/php-cgi-56.sock:", host: "127.0.0.1", referrer: "http://127.0.0.1/list/dianshi.html"

代码部署到服务器 ngnix日志出现了大量的recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 127.0.0.1, server: 127.0.0.1, request: "GET /data.php?random=0YMkNeNyJhY3kQiOiJMrIiwiYdCI6M0TYxODNc2MDYk4MjkyMNX0_&callback=jQuery35104466580732208365_1618760682879&_=1618760682880 HTTP/1.1", upstream: "fastcgi://unix:/tmp/php-cgi-56.sock:", host: "127.0.0.1", referrer: "http://127.0.0.1/list/dianshi.html"

各种百度都说是ngnix的配置和pph-fpm的配置问题最后发现我的都不是

而是安全规则中的入口和出口的开放端口规则设置的不合适我把出口的所有端口打开就好了
