The installation process may slightly vary depending on the database you want to install and the operating system your VPS server is running on. Here are two general guides on how to install MySQL and PostgreSQL on a VPS running Ubuntu:
1. MySQL installation
- Access your server through the command line.
- Update your server’s package manager, “apt”. You can do this by running `sudo apt-get update`.
- Begin the MySQL installation by running `sudo apt-get install mysql-server`.
- During the installation process, you will be required to create and confirm a root password for the MySQL system.
- After the installation is complete, run `sudo mysql_secure_installation` to improve the security of your MySQL installation. Follow the prompts to set your preferences.
- To verify MySQL is installed and running, execute `systemctl status mysql.service`.
1. PostgreSQL installation
- Access your server through the command line.
- Update your server’s package manager, “apt”. You can do this by running `sudo apt-get update`.
- Begin the PostgreSQL installation by running `sudo apt-get install postgresql postgresql-contrib`.
- Once the installation is complete, you can switch into the PostgreSQL prompt by typing `sudo -u postgres psql`.
- To exit the postgres console, use the command `\q`.
Please adjust these steps depending on the specifics of your server’s OS and the database system you chose. Always refer to the official documentation of the respective database for the most accurate information.
Before starting, make sure you have full permissions (usually as a root user) on your VPS. Use secure keys instead of passwords to log into your server for added security.
Please note that you are responsible for the management and security of your VPS. Be sure to properly secure your server and the database installation according to best practices.
