Installing OpenCart on a VPS can be a straightforward process. Here is a step-by-step guide to help you install OpenCart on your Virtual Private Server (VPS):
- Connect to your VPS: Use SSH or any other remote access method to connect to your VPS.
- Update the server: Run the command sudo apt update to update the system packages on your VPS.
- Install Apache web server: Run the command sudo apt install apache2 to install Apache on your VPS. Confirm the installation when prompted.
- Install MySQL database server: Run the command sudo apt install mysql-server to install MySQL on your VPS. Follow the prompts to set a root password for your MySQL server.
- Install PHP and required extensions: Run the command sudo apt install php libapache2-mod-php php-mysql php-common php-cli php-fpm php-curl php-gd php-xml php-zip php-mbstring to install PHP and the necessary PHP extensions for OpenCart.
- Configure PHP settings: Open the PHP configuration file with the command sudo nano /etc/php/7.4/apache2/php.ini (replace '7.4' with your PHP version if different). Adjust the following settings: Memory_limit: Set memory_limit = 256M Upload_max_filesize: Set upload_max_filesize = 64M Max_execution_time: Set max_execution_time = 180 Save the changes and exit.
- Enable required Apache modules: Run the command sudo a2enmod rewrite to enable the Apache rewrite module.
- Restart Apache: Restart the Apache web server for the changes to take effect with the command sudo service apache2 restart.
- Create a MySQL database and user: Log in to MySQL using the command sudo mysql -u root -p. Enter your MySQL root password and execute the following commands to create a new database and user: CREATE DATABASE opencartdb; GRANT ALL PRIVILEGES ON opencartdb.* TO 'opencartuser'@'localhost' IDENTIFIED BY 'password'; FLUSH PRIVILEGES; EXIT; Replace 'opencartdb' with your preferred database name, 'opencartuser' with your preferred username, and 'password' with your preferred password.
- Download and extract OpenCart: Go to the OpenCart official website and download the latest version of OpenCart. Upload the downloaded ZIP file to your VPS using SFTP or any other file transfer method. Extract the contents of the ZIP file into your web directory (usually /var/www/html/).
- Set appropriate permissions: Run the command sudo chown -R www-data:www-data /var/www/html to give ownership of the files to the web server.
- Access the OpenCart installation: In your web browser, enter your server's IP address or domain name. You will be prompted with the OpenCart installation wizard.
- Follow the wizard: Provide the necessary information during the installation process, such as database details, username, password, and store settings.
- Complete the installation: Once you have filled in all the required information, click on the "Install" button to complete the OpenCart installation.
- Remove installation directory: For security reasons, it is recommended to remove the OpenCart installation directory. Run the command sudo rm -rf /var/www/html/install/ to delete the directory.
That's it! You have successfully installed OpenCart on your VPS. You can now access your OpenCart store and start customizing it to fit your needs.

How to set up a domain for OpenCart on a VPS?
To set up a domain for OpenCart on a VPS, follow these steps:
- Purchase a domain name: Go to a domain registrar (such as GoDaddy or Namecheap) and purchase a domain name for your OpenCart website.
- Setup DNS records: Log in to your domain registrar's website and update the Domain Name System (DNS) settings for the domain name you purchased. Set up the following DNS records: A record: Create an A record pointing the domain (e.g., example.com) to your VPS IP address. CNAME record: Create a CNAME record pointing the 'www' subdomain (e.g., www.example.com) to the domain name (e.g., example.com).
- Configure VPS server: Connect to your VPS server using SSH or a similar tool. Ensure that your VPS is powered on and accessible.
- Install a web server: Install a web server like Apache or Nginx on your VPS. Use the OS package manager or manually compile and install the server. Configure the webserver to listen on port 80 and respond to your domain name.
- Install PHP and required extensions: Install PHP on your VPS, along with the necessary extensions like MySQLi and GD. These extensions are required for OpenCart to function properly. Again, use the OS package manager or compile manually, depending on your server setup.
- Set up a MySQL database: Create a new MySQL database and user for your OpenCart installation. Note down the database credentials as you will need them during the OpenCart setup.

- Configure SSL (optional): If you want to secure your OpenCart website with SSL, obtain an SSL certificate and configure it on your web server. You can obtain a free SSL certificate from Let's Encrypt or purchase one from a trusted provider.
- Test your setup: After completing the OpenCart installation, verify that your website is accessible and functioning correctly. Test various features like adding products, registering users, and making purchases to ensure everything is working as expected.
By following these steps, you can successfully set up a domain for OpenCart on a VPS.
How to troubleshoot common errors during OpenCart installation on a VPS?
When installing OpenCart on a VPS (Virtual Private Server), you may encounter common errors. Here are some troubleshooting steps to help you resolve them:
- Check PHP Version: Ensure that your VPS meets the minimum PHP version requirement of OpenCart. You can check the PHP version by creating a PHP info file with the following code:
1 2 3
<?php phpinfo(); ?>
Access the file via a web browser and search for "PHP Version". If it is not compatible, update your PHP version.
- Verify File Permissions: Confirm that the file and folder permissions are set correctly. OpenCart requires certain directories to be writable. Typically, you should set the permissions to 755 for directories and to 644 for files.
- Modify PHP Settings: Adjust some PHP settings to meet OpenCart requirements. Edit your PHP configuration file (php.ini) and update the following values:
memory_limit = 256M max_execution_time = 180
Save the file and restart your web server.
- Enable Required PHP Extensions: Make sure that all the necessary PHP extensions are enabled. Key extensions include "curl", "dom", "gd", "json", "mbstring", "mysqli", "openssl", and "zip". Activate any missing extensions by modifying your PHP configuration file (php.ini) and uncommenting the relevant lines or contacting your hosting provider to enable them for you.
- Verify Database Details: Double-check the database details entered during the installation process (database name, username, password, and host). Ensure that the credentials are accurate and that the database exists.
- Clear Cache: OpenCart uses a caching mechanism that can sometimes cause issues during installation or after modifications. Delete the contents of the corresponding cache directory located in "system/storage/cache/".
- Disable .htaccess: Rename or remove the .htaccess file temporarily located in your OpenCart root directory. This step helps identify whether the issue is related to rewrite rules set in the .htaccess file.
- Monitor Error Logs: Check the server's error logs for any related errors. The location of these logs varies based on your server setup. If you're using Apache, the error logs are typically found in "/var/log/httpd/error_log" or "/var/log/apache2/error.log". For Nginx users, look for "/var/log/nginx/error.log". Analyzing the log files can often give you clues about the root cause of the problem.
- Seek Community Support: Reach out to the OpenCart community for assistance if you are unable to resolve the issue. You can ask for help on the OpenCart forums or consult the documentation and user guides provided by OpenCart.
Remember to always backup your files and database before making any changes to your VPS. This ensures that you can revert to a working state in case something goes wrong during troubleshooting.
