nginx我一直在學習如何在新伺服器上設定簡單的代理Ubuntu 18.04.5 LTS。我想了解為什麼每次嘗試設定此功能時我都會遇到相同的問題。
/var/www/html/安裝 nginx 後，我在輸入 時收到位於的預設歡迎網站mydomain.com。然後，我在 處建立一個設定檔etc/nginx/sites-available/並從 simlink 到它etc/nginx/sites-enabled/。
然後，我使用 重新啟動 nginx service nginx restart。然而，這一步之後並沒有立即起作用。我的意思是，我不斷從 nginx 獲取預設歡迎頁面，而不是我試圖提供的頁面，我必須使用連接埠號來訪問該頁面，如mydomain.com:3000.
我嘗試刪除default下面的配置文件/etc/nginx/sites/enabled/，然後重新啟動服務，但沒有成功。然而，在我重新創建 simlink 並unlink使用rm.但我沒有立即工作，因為我還必須重命名我的配置文件，這是與我提前設置的另一個工作伺服器的唯一區別。
/etc/nginx/sites-enabled/這是我輸入的最終解決問題的命令（缺少的行是ls命令）：
138 sudo rm default
140 sudo service nginx restart
141 sudo ln -s ../sites-available/default .
143 sudo service nginx restart
157 sudo unlink /etc/nginx/sites-enabled/default
158 cd sites-enabled/
162 sudo service nginx configtest
163 sudo service nginx restart
165 sudo unlink mydomain-server
168 cd sites-available/
171 sudo mv mydomain-server mydomain
176 cd sites-enabled/
179 sudo ln -s ../sites-available/mydomain .
182 sudo nginx -t
183 sudo service nginx restart
對可能出現的問題有什麼想法嗎？我有一種感覺，在我不做任何重要改變的情況下，它總是會起作用，所以我應該更有耐心，還是我在過程中錯過了一些真正重要的東西？
另外，我省略了配置/伺服器詳細信息，因為每次嘗試任何配置時我都會遇到這個問題，但仍然不知道如何使其在第一次嘗試時工作。
編輯 ：nginx -T根據評論中的要求添加輸出。
