我刚刚安装了带有 LEMP 和 wordpress 的 Ubuntu 服务器 16.04。但似乎我错过了此过程中的某个步骤，因为我在网站上遇到了以下错误。
http error: curl error 7: failed to connect to wordpress.org port 80.
网站运行良好，除此之外，它是在虚拟机中配置的，因为我正在开发一个网站，首先在我的本地机器上测试本地的所有内容。
这是我的配置文件：
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/;
}
}
请注意，我已经使用以下规则配置了防火墙：

所以在图像中一切都很好，但也许缺少一些东西，或者我不知道我安装了 fpm fast cgi。
wordpress 无法通过 http 请求连接到网络。
我真的不知道那是什么，任何线索都会受到欢迎。
在此先感谢您的帮助。
答案1
你的服务器叫 wordpress.org 吗？
根据您的配置文件它是：
server_name 192.168.1.3; #ipaddress;
如果您想在本地使用服务器名，则必须在 /etc/hosts 中输入 ip 地址和名称，如果必须从外部访问，则必须拥有 ISP 提供的主机名和 dns 条目。并且必须在路由器中设置适当的端口转发。
答案2
如果问题出在 curl 上，我会首先尝试从控制台运行它来检查是否是网络相关的问题（防火墙等）。
似乎如果您启用了 SELINUX，这可能会导致 Web 服务器阻止请求。如下所示https://wordpress.org/support/topic/error-curl-error-7-3/
如果 curl 从控制台工作并且您没有启用 SELINUX，我会测试一个小型 php 脚本来验证 curl 是否正常工作，以及针对哪些主机更好地调试它。
干杯
答案3
检查 SELinux。它会自动重新打开并干扰 CURL。
要暂时禁用 SELinux 直到 Linux 系统重新启动，请执行setenforce 0。
