我新安裝了帶有 LEMP 和 wordpress 的 Ubuntu 伺服器 16.04。但我似乎錯過了這個過程中的一步，因為我在網站上出現以下錯誤。
http error: curl error 7: failed to connect to wordpress.org port 80.
這些網站工作正常，除了在我開發網站時在虛擬機器中配置之外，首先在本地電腦上測試本地的所有內容。
這是我的設定檔：
server {
listen 80;
server_name 192.168.1.3; #ipaddress;
root /usr/share/nginx/mrupgrade.be/;
index index.php index.html index.htm;
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
location / {
try_files $uri $uri/ /index.php;
}
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location ~ \.php$ {
try_files $uri = 404;
fastcgi_pass unix:/run/php/php7.0-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
root /usr/share/nginx/mrupgrade.be/;
}
}
請注意，我已經使用這些規則配置了防火牆：

所以在圖像中一切都很好，期望一些東西可能缺少一個庫或我不知道我安裝了 fpm fast cgi。
wordpress 無法透過 http 請求連接到網路。
我真的不知道這可能是什麼，任何線索都會受到歡迎。
在此先感謝您的幫忙。
答案1
您的伺服器名為 wordpress.org 嗎？
根據你的配置文件，它是：
server_name 192.168.1.3; #ipaddress;
如果您想在本機上使用伺服器名，則必須在 /etc/hosts 中輸入 ip 位址和名稱，如果必須可從外部訪問，則必須有 ISP 提供的主機名稱和 dns 條目。並且您必須在路由器中設定適當的連接埠轉送。
答案2
如果curl是問題所在，我會先嘗試從控制台運行它以檢查是否是與網路相關的問題（防火牆等）
看來，如果您啟用了 SELINUX，這可能會導致網頁伺服器阻止請求。正如這裡所見https://wordpress.org/support/topic/error-curl-error-7-3/
如果curl可以從控制台運行並且您沒有啟用SELINUX，那麼我會測試一個小的php腳本來驗證curl是否正常工作，以及哪些主機可以更好地調試它。
乾杯
答案3
檢查 SELinux。它會自行重新打開並幹擾 CURL。
若要暫時停用 SELinux，直到 Linux 機器重新啟動，請執行setenforce 0.
