Setup Environment

Setup PHP on Nginx with fastCGI (PHP-FPM)

sudo apt-get update -y
sudo apt-get upgrade -y

sudo apt-get install nginx -y
sudo systemctl status nginx

sudo apt-get install php8.1-fpm -y
sudo systemctl status php8.1-fpm

sudo vim /etc/nginx/sites-available/default

server {
  # Example PHP Nginx FPM config file
  listen 80 default_server;
  listen [::]:80 default_server;
  root /var/www/html;

  # Add index.php to setup Nginx, PHP & PHP-FPM config
  index index.php index.html index.htm index.nginx-debian.html;

  server_name _;

  location / {
    try_files $uri $uri/ =404;
  }

  # pass PHP scripts on Nginx to FastCGI (PHP-FPM) server
  location ~ \.php$ {
    include snippets/fastcgi-php.conf;

    # Nginx php-fpm sock config:
    fastcgi_pass unix:/run/php/php8.1-fpm.sock;
    # Nginx php-cgi config :
    # Nginx PHP fastcgi_pass 127.0.0.1:9000;
  }

  # deny access to Apache .htaccess on Nginx with PHP, 
  # if Apache and Nginx document roots concur
  location ~ /\.ht {
    deny all;
  }
} # End of PHP FPM Nginx config example

sudo nginx -t
sudo systemctl restart nginx

sudo chmod -R 777 /var/www/html
echo "<?php phpinfo(); ?>" >> /var/www/html/info.php
#check with localhost/info.php
  • Đầu tiên cần share thư mục trên máy host vào Ubuntu VM
  • Sau đó link từ thư mục đó trên máy host đến /var/www/html/index.php

ln -s /mnt/hgfs/share-folder/index.php /var/www/html/index.php
