+# Guide: Install Apache, PHP, and Deploy PHP Service with SQLite on Ubuntu VPS
+
+This guide will walk you through the steps to install Apache, PHP, and deploy a PHP service using SQLite on your new Ubuntu VPS.
+
+---
+
+# 1. Update and Upgrade the System & installaion Code Server
+Before starting, update the package lists and upgrade existing packages:
+To install code-server (a self-hosted version of Visual Studio Code) on Ubuntu, follow these steps. Code-server allows you to run VS Code in the browser and access it remotely.
+
+## 1.1 Update and Install Dependencies
+First, ensure your system is up to date and install any required dependencies:
+
+```bash
+sudo apt update
+sudo apt upgrade -y
+sudo apt install curl -y
+```
+## 1.2 install.sh
+The easiest way to install code-server is to use our install script for Linux, macOS and FreeBSD. The install script attempts to use the system package manager if possible.
+
+To install, run:
+```bash
+curl -fsSL https://code-server.dev/install.sh | sh
+```
+
+Now visit http://127.0.0.1:8080. Your password is in ~/.config/code-server/config.yam
+```bash
+sudo systemctl enable --now code-server@$USER
+```
+Change the options in the config.yaml. 0.0.0.0:8888, password, and etc
+```bash 
+nano ~/.config/code-server/config.yaml
+```
+After change the configuration, restart the service
+```bash
+sudo systemctl restart code-server@$USER
+```
+## 1.3.1. Install UFW
+First, install UFW if it's not already installed on your system:
+
+```bash
+sudo apt update
+sudo apt install ufw -y
+```
+## 1.3.2. Check UFW Status
+After installation, you can check the status of UFW:
+
+```bash
+sudo ufw status
+```
+By default, UFW is inactive, so it will show Status: inactive.
+
+## 1.3.3. Allow SSH Connections
+Before enabling UFW, allow SSH connections to avoid locking yourself out of the server:
+
+```bash
+sudo ufw allow ssh
+```
+Alternatively, you can specify the port for SSH (default is 22):
+
+```bash
+sudo ufw allow 22/tcp
+```
+## 1.3.4. Allow HTTP and HTTPS
+Next, allow HTTP (port 80) and HTTPS (port 443) traffic through the firewall:
+
+```bash
+sudo ufw allow http
+sudo ufw allow https
+```
+Or, you can manually specify the ports:
+
+```bash
+sudo ufw allow 80/tcp  # For HTTP
+sudo ufw allow 443/tcp  # For HTTPS
+```
+## 1.3.5. Enable UFW
+Once the necessary ports are allowed, you can enable UFW to start filtering traffic:
+
+```bash
+sudo ufw enable
+```
+## 1.3.6. Check UFW Status
+To verify that UFW is active and the correct ports are open, run:
+
+```bash
+sudo ufw status verbose
+```
+This will show the list of allowed services and their associated ports. You should see something like:
+
+```bash
+Status: active
+
+To                         Action      From
+--                         ------      ----
+22                         ALLOW       Anywhere
+80                         ALLOW       Anywhere
+443                        ALLOW       Anywhere
+22 (v6)                    ALLOW       Anywhere (v6)
+80 (v6)                    ALLOW       Anywhere (v6)
+443 (v6)                   ALLOW       Anywhere (v6)
+```
+
+# 2. Install Apache Web Server
+Install Apache by running the following command:
+
+```bash
+sudo apt install apache2 -y
+```
+## 2.1. Start and Enable Apache
+Start the Apache service and enable it to start on boot:
+
+```bash
+sudo systemctl start apache2
+sudo systemctl enable apache2
+```
+## 2.2. Check Apache Status
+Verify that Apache is running:
+
+```bash
+sudo systemctl status apache2
+Visit http://<your_server_ip> in your browser, and you should see the default Apache welcome page.
+```
+
+# 3. Install PHP and Required Modules
+Install PHP and the required modules to run PHP with Apache:
+
+```bash
+sudo apt install php libapache2-mod-php php-sqlite3 -y
+```
+3.1. Check PHP Installation
+Verify that PHP is installed by running:
+
+```bash
+php -v
+```
+This will display the installed PHP version.
+
+# 4. Configure Apache to Use PHP
+Ensure that Apache is configured to serve PHP files. The libapache2-mod-php package should automatically enable PHP, but you can confirm this by running:
+
+```bash
+sudo a2enmod php
+```
+Then, restart Apache to apply any changes:
+
+```bash
+sudo systemctl restart apache2
+```
+
+# 5. Clone the Repository to Your VPS
+## 5.1: Clone from GitHub
+If you want to clone the repository directly from GitHub, follow these steps:
+
+Install Git (if not already installed):
+
+```bash
+sudo apt install git -y
+```
+Clone the GitHub repository to /var/www/html:
+
+```bash
+sudo git clone https://github.com/username/repository.git /var/www/html/
+```
+Replace https://github.com/username/repository.git with the URL of your GitHub repository.
+
+# 6. Set Correct Permissions for Apache (www-data)
+After cloning the repository, you need to ensure that Apache (which runs as the www-data user) can access and serve the files.
+
+## 6.1 Change Ownership to www-data:
+
+```bash
+sudo chown -R www-data:www-data /var/www/html
+```
+This command changes the ownership of all files in the /var/www/html directory to the www-data user and group, which is the user under which Apache runs.
+
+## 6.2 Set Correct Permissions for Files:
+
+Optionally, you can ensure the correct read/write/execute permissions for the files:
+
+```bash
+sudo find /var/www/html -type d -exec chmod 755 {} \;  # Directories - rwxr-xr-x
+sudo find /var/www/html -type f -exec chmod 644 {} \;  # Files - rw-r--r--
+```
+- Directories: 755 (read, write, and execute for the owner, read and execute for others).
+- Files: 644 (read and write for the owner, read-only for others).
+
+# 7. Configure Apache (Optional)
+You may want to set up a virtual host if you need a custom domain or to ensure proper configuration for your service.
+
+Example of a Virtual Host Configuration:
+## 7.1 Create a Virtual Host File:
+
+```bash
+sudo nano /etc/apache2/sites-available/your-site.conf
+```
+## 7.2 Add the Virtual Host Configuration:
+
+Replace your-site.com with your domain or IP address:
+
+```bash 
+apache
+<VirtualHost *:80>
+    ServerAdmin webmaster@localhost
+    DocumentRoot /var/www/html
+    ServerName your-site.com
+
+    <Directory /var/www/html>
+        Options Indexes FollowSymLinks
+        AllowOverride All
+        Require all granted
+    </Directory>
+
+    ErrorLog ${APACHE_LOG_DIR}/error.log
+    CustomLog ${APACHE_LOG_DIR}/access.log combined
+</VirtualHost>
+```
+## 7.3 Enable the Virtual Host:
+
+```bash
+sudo a2ensite your-site.conf
+```
+Enable mod_rewrite (if necessary):
+
+If you're using .htaccess or need URL rewriting, enable the mod_rewrite module:
+
+```bash
+sudo a2enmod rewrite
+```
+Restart Apache:
+
+```bash
+sudo systemctl restart apache2
+```
