在 nginx 服务器上部署 CodeIgniter 3 项目后出现错误 500

Question

我正在使用 Ubuntu 18.04 VPS 并尝试在 nginx 服务器上部署 CodeIgniter 项目。不幸的是，nginx 配置文件似乎有问题。这是文件：

nginx 配置：

server {
    listen 80;
    listen [::]:80;

    # Server Name
    server_name doamin.com;
    
    # Document Root
    root /var/www/html/domain.com;

    # Add index.php to the list if you are using PHP
    index index.php index.html index.htm;
    
    location / {
        try_files $uri $uri/ /index.php$is_args$args;
    }
    
    # pass PHP scripts to FastCGI server
    #
    location ~ \.php$ {
        include snippets/fastcgi-php.conf;

        # With php-fpm:
        fastcgi_pass unix:/run/php/php7.2-fpm.sock;
    }


    error_page 404 /index.php;

    # deny access to hidden files such as .htaccess & .git
    location ~ /\. {
        deny all;
    }
    
}
