Question

我正在尝试在ubuntu 18.04上使用nginx运行php7.2-fpm来运行Wordpress。 Nginx可以正常工作，但是php无法正常工作。

我的nginx配置文件：

server {

    listen 80;
    charset UTF-8;
    server_name example.com www.example.com;
    
    location ~ \.php$ {
        try_files            $uri = 404;
        fastcgi_pass         unix:/run/php/php7.2-fpm.sock;
        fastcgi_index        index.php;
        include              fastcgi_params;
        fastcgi_read_timeout 300;
    }
    
    location / {
        root  /data/web;
        index index.html index.htm;
    }

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}

对不起，我的英文简短。

Answer 1

您在nginx配置文件中有错误的配置。

首先，您在root部分中指定index和location \指令。

location / {
        root  /data/web;
        index index.html index.htm;
}

该部分仅在其他所有部分都不匹配时才起作用，因为它具有短掩码长度（/是一个符号）

每个以URL结尾的.php，例如phpinfo.php或index.php都将匹配到location ~ \.php$部分：

location ~ \.php$ {
        try_files            $uri = 404;
        fastcgi_pass         unix:/run/php/php7.2-fpm.sock;
        fastcgi_index        index.php;
        include              fastcgi_params;
        fastcgi_read_timeout 300;
}

但是-没有root和index指令（顺便说一下index是可选的，但在您的情况下，第一个是必需的）。

有两种解决方案：

首先，在root部分中指定index和location ~ \.php$指令：

location ~ \.php$ {
        try_files            $uri = 404;
        root                 /data/web;
        index                index.php index.html index.htm;
        fastcgi_pass         unix:/run/php/php7.2-fpm.sock;
        fastcgi_param        SCRIPT_FILENAME $document_root/$fastcgi_script_name;
        fastcgi_index        index.php;
        include              fastcgi_params;
        fastcgi_read_timeout 300;
}

第二个方法是将root和index放在全局上下文中（在server内部）：

server {

    listen 80;
    charset UTF-8;
    server_name example.com www.example.com;
    root  /data/web;
    index index.php index.html index.htm;

    ...

}

UPD：同样，必须在fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name;之后添加fastcgi_pass指令

我强烈建议您阅读Official nginx.org "Begginers guide"，以更好地了解事物的工作原理。
