無法連線到伺服器連接埠 443：連線被拒絕

我的伺服器上運行著一個 Web 伺服器，位址為 127.0.0.1:8088 我想從網路存取它。

執行 Web 伺服器時 ss -nplut 的輸出：

tcp LISTEN 0 1024 127.0.0.1:8088 0.0.0.0:* users:(("ctprods",pid=2042,fd=9))

輸出 ss -nplut |grep 443

tcp LISTEN 0 511 *:443 *:*

我建立了一個 apache 虛擬主機（網站已啟用，apache 已重新載入）：

<VirtualHost *:443>
 # The ServerName directive sets the request scheme, hostname and port that
    # the server uses to identify itself. This is used when creating
    # redirection URLs. In the context of virtual hosts, the ServerName
    # specifies what hostname must appear in the request's Host: header to
    # match this virtual host. For the default virtual host (this file) this
    # value is not decisive as it is used as a last resort host regardless.
    # However, you must set it for any further virtual host explicitly.
    ServerName cyprientaque.com
    ServerAlias ctprods.cyprientaque.com

    ServerAdmin [email protected]

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
    RewriteEngine on
# Some rewrite rules in this file were disabled on your HTTPS site,
# because they have the potential to create redirection loops.

#       RewriteCond %{SERVER_NAME} =ctprods.cyprientaque.com
#       RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]

     <Proxy *>
             Require all granted
     </Proxy>
             ProxyPass / http://127.0.0.1:8088/
             ProxyPassReverse / http://127.0.0.1:8088/

SSLCertificateFile /etc/letsencrypt/live/ctprods.cyprientaque.com-0001/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/ctprods.cyprientaque.com-0001/privkey.pem
Include /etc/letsencrypt/options-ssl-apache.conf
</VirtualHost>

我使用 let encrypt 建立了一個 ssl 憑證：

Certificate Name: ctprods.cyprientaque.com-0001
Serial Number: 39538aec7472a644e8d22887f858de17177
Domains: ctprods.cyprientaque.com
Expiry Date: 2020-11-17 10:59:58+00:00 (VALID: 89 days)
Certificate Path: /etc/letsencrypt/live/ctprods.cyprientaque.com-0001/fullchain.pem
Private Key Path: /etc/letsencrypt/live/ctprods.cyprientaque.com-0001/privkey.pem

我的 ctprods.cyprientaque.com 的 dns 提供者中有 A 記錄，指向我的伺服器 IP

但是當我嘗試使用 curl 存取我的伺服器時，出現錯誤：

$ curl -X GET https://ctprods.cyprientaque.com/projects
curl: (7) Failed to connect to ctprods.cyprientaque.com port 443: Connection refused

我看不到請求 tcpdump 連接埠 443..

答案1

您的 Apache 未偵聽連接埠 443。使用連接埠 443 和您的憑證設定第二個 VirtualHost，並確保您Listen 443的 Apache 配置中有一個指令。您的憑證不屬於 VirtualHost :80。

以上是基於問題中的錯誤訊息。無論您在此期間做了什麼，您的伺服器現在都可以透過 HTTPS 進行修復。

$ curl -X GET https://ctprods.cyprientaque.com/projects
"Invalid JWT"
