ポート80だけが使用中であっても、任意のポートでUbuntuでnginxを起動できません。

Question

Ubuntu16.04でnginxを起動できません。

sudo /etc/init.d/nginx startを実行するとエラーが発生します。私は呼び出すことによって、エラー・メッセージを深く見て

(env) agaidis@Computer:~$ sudo /etc/init.d/nginx start 
[....] Starting nginx (via systemctl): nginx.serviceJob for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details. 
failed! 

、

sudo systemctl status nginx.service 

私は、次のようなフィードバックを得る：

(env) agaidis@Computer:~/www$ sudo systemctl status nginx.service

を私はnginxのを取得するためにthis websiteに手順を追っていると、ガンコーンが走っている。私は自分の問題を修正するためにウェブ全体を見てきましたが、何も動いていません。

私は、他のポート番号を試してみましたが聞いて、ポート8888で応答するのnginxされていないので、私は私の/etc/nginx/sited-available/defaultでポートを切り替えて、/etc/nginx/sited-available/<name of flask app>、および/etc/nginx/sited-enabled/<name of flask app>すべてのポート80上で実行されている別のサーバーを持っています。残念ながら、これはまったく役に立たないようです。

マイ/etc/nginx/sited-available/defaultファイルはそうのようになります。

マイ/etc/nginx/sited-enabled/<name of flask app>と/etc/nginx/sited-available/<name of flask app>ファイルには、次のようになります。

server { 
    location/{ 
     proxy_pass http://localhost:8888; 
     proxy_set_header Host $host; 
     proxy_set_header X-Real-IP $remote_addr; 
    } 
    location /static { 
     alias /home/agaidis/www/<name of flask app>/static/; 
    } 
} 

私が起動しようとする前に、私が試してみましたいくつかの他のものはsudo apt-get updateとsudo apt-get upgrade nginxが含まれますサーバ。

ポート80で動作している現在のサーバーを停止しないで問題を解決する方法はありますか？任意のすべてのヘルプは大いに感謝しています:)

Answer 1

私は/etc/nginx/sited-available/<name of flask app>ファイルの先頭にlisten 8080;を追加しました。したがって、それはなった：

server { 

    listen 8080; 

    location/{ 
     proxy_pass http://localhost:8888; 
     proxy_set_header Host $host; 
     proxy_set_header X-Real-IP $remote_addr; 
    } 
    location /static { 
     alias /home/agaidis/www/<name of flask app>/static/; 
    } 
} 

それは私の問題を修正しました。
