How to Install MariaDB/MySQL/PerconaDB on AnonVM: A Step-by-Step Guide

MariaDB, MySQL, and PerconaDB are popular open-source database management systems used by businesses and developers worldwide. If you're hosting your website or application on AnonVM, it's crucial to choose the best database server for your needs. This guide will help you install and configure MariaDB, MySQL, or PerconaDB on your AnonVM server, with detailed steps and optimizations to ensure a fast and secure database environment.

Prerequisites

Before proceeding with the installation, ensure the following:

• A VPS or Dedicated Server: Hosted on AnonVM for offshore security.
• Root/Sudo Access: You need root or sudo privileges to install and configure database servers.
• Linux-based OS: This guide assumes a Debian-based (Ubuntu/Debian) or CentOS operating system.

Step 1: Update Your System

Start by updating the package list and ensuring that your system has the latest updates:

For Ubuntu/Debian-based systems:

For CentOS-based systems:

Step 2: Install Dependencies

Before installing MariaDB/MySQL/PerconaDB, you may need to install some dependencies:

For Ubuntu/Debian-based systems:

For CentOS-based systems:

Step 3: Install MariaDB/MySQL/PerconaDB

Choose the database management system that suits your needs:

Install MariaDB (Recommended for most users):

1. For Ubuntu/Debian: MariaDB is available in the default Ubuntu repositories, but you may want to install the latest version from the MariaDB repository:

    

   sudo apt install software-properties-common sudo add-apt-repository ppa:mariadb/mariadb-10.5 sudo apt update sudo apt install mariadb-server mariadb-client -y

2. For CentOS: MariaDB is available from the default CentOS repository:

    

   sudo yum install mariadb-server mariadb -y

Install MySQL:

1. For Ubuntu/Debian: MySQL can be installed directly from the repository:

    

   sudo apt install mysql-server mysql-client -y

2. For CentOS: Use the MySQL official repository for CentOS:

    

   sudo yum localinstall https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm sudo yum install mysql-server -y

Install PerconaDB:

PerconaDB is a high-performance, open-source alternative to MySQL with extra features and optimizations. For PerconaDB, install the official Percona repository:

1. For Ubuntu/Debian:

    

   wget https://repo.percona.com/apt/percona-release_latest.generic_all.deb sudo dpkg -i percona-release_latest.generic_all.deb sudo apt update sudo apt install percona-server-server-5.7 percona-server-client-5.7 -y

2. For CentOS:

    

   sudo yum install https://repo.percona.com/yum/percona-release-latest.noarch.rpm sudo yum install percona-server-server percona-server-client -y

Step 4: Start and Secure the Database Server

Once the installation is complete, start your database server:

For MariaDB/MySQL/PerconaDB:

Enable the service to start automatically at boot:

Now, it’s time to secure the installation using the included mysql_secure_installation script:

This script will prompt you to set a root password, remove insecure default settings, and configure other security features.

Step 5: Test the Database Server

To confirm that the database server is running correctly, log into the database:

You should see the MySQL/MariaDB/PerconaDB prompt. If you see this prompt, it means the server is running correctly.

Step 6: Configure Database for Performance (Optional)

After installation, it's important to optimize your database for performance. Depending on your server's hardware and requirements, you can tweak the database's configuration.

1. Edit Configuration Files:

   The configuration file is typically located at:

   • MariaDB/MySQL: /etc/mysql/my.cnf or /etc/my.cnf
   • PerconaDB: /etc/my.cnf

   Open the configuration file for editing:

    

   sudo nano /etc/mysql/my.cnf # For MariaDB/MySQL sudo nano /etc/my.cnf # For PerconaDB

2. Optimize Key Parameters:

   Modify parameters based on your server’s resources. A few common parameters to optimize include:

   • innodb_buffer_pool_size: Set this to about 70-80% of your system’s available memory for better performance.
   • max_connections: Set the number of allowed concurrent connections.
   • query_cache_size: Allocate memory for query caching to improve performance for read-heavy applications.

   Example for MariaDB/MySQL:

    

   innodb_buffer_pool_size = 1G max_connections = 500 query_cache_size = 64M

3. Restart the Database Server:

   After making changes, restart the database server for the changes to take effect:

    

   sudo systemctl restart mariadb # For MariaDB sudo systemctl restart mysql # For MySQL sudo systemctl restart percona-server # For PerconaDB

Step 7: Monitor Database Performance

It’s essential to monitor the database’s performance, especially if your application scales up. You can use various tools like MySQLTuner and Percona Monitoring and Management (PMM) for more in-depth performance analysis.

MySQLTuner:

Install and run MySQLTuner to analyze the performance of your database:

Percona Monitoring and Management (PMM):

Percona offers PMM for monitoring, which is a more advanced solution. You can install and configure PMM for comprehensive database monitoring.

Step 8: Create and Manage Databases and Users

Create a new database:

Create a new user and grant privileges:

Step 9: Set Up Backups

Regular backups are essential to ensure that your data is safe. You can use mysqldump for manual backups or configure automatic backups using cron jobs.

Example: Backup a Database

Conclusion

By following these steps, you’ve successfully installed and configured MariaDB, MySQL, or PerconaDB on your AnonVM server. You now have a secure, high-performance database setup that’s optimized for your hosting needs.

Key Points:

• MariaDB, MySQL, and PerconaDB are powerful database management systems suitable for different use cases.
• Configuring MariaDB/MySQL/PerconaDB correctly can significantly improve your server’s performance.
• Regular backups and performance monitoring are critical for maintaining database health.
