nginx報502修復日志 upstream prematurely closed

nginx錯誤日志

    2020/08/16 20:22:06 [error] 288416#288480: *1 upstream prematurely closed connection while reading response header from upstream, client: 127.0.0.1, server: localhost, request: "GET /aa.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "localhost", referrer: "http://localhost/"

然后我想是不是9000端口被占用了（臨時想出來的），然后打開cmd窗口

       我們看到是PID是300884，然后輸入命令：tasklist | findstr “301816”

原來是IDE占用了9000端口（IDE故意的吧，偏偏每次都默認占用這個端口）。這下問題好解決了，先把ide關閉，再重啟nginx，然后再開IDE（一定要在nginx啟動之后）。再去打開postman請求本地接口，一切又正常了 ヽ(￣▽￣)ﾉ
