私が経験してる502 GatewayディレクトリにPHPファイルにアクセスする際のエラーを(http://example.com/dev/index.php)。ログはこれを単に示します:
2011/09/30 23:47:54 [error] 31160#0: *35 connect() failed (111: Connection refused) while connecting to upstream, client: xx.xx.xx.xx, server: domain.com, request: "GET /dev/ HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "domain.com"
これを経験したことはありません。このタイプの502 Gatewayエラーの解決策は何ですか?
