What is MySQL Remote Access?

MySQL remote access helps connect to a database server from machines across networks.

MySQL only accepts connections from "localhost (127.0.0.1)" by default. Users can only connect from the same server where MySQL is set up. This default behavior is intentional. MySQL's security-first approach helps prevent unauthorized access. Modern applications often need database access from many sources, such as:

• Web servers
• Application servers
• Development machines
• Monitoring tools

When Is Remote MySQL Access Necessary?

• Distributed Systems: Modern web applications often separate web servers from database servers. For example, your WordPress site might run on one server. Its MySQL database might operate on another for better performance.
• Cloud Environments: Platforms like AWS, Azure, & Google Cloud deploy databases across different instances. They even use different availability zones.
• Remote Development: Development teams from various locations need access to central development databases. They also need access to staging databases.
• Backup and Monitoring: External backup services & monitoring tools need access to this feature. They also need remote access to perform their functions.

CloudPanel MySQL Remote Access Setup

1. Prerequisites and Planning

i. System Requirements

• MySQL 5.7+ (MySQL 8.0+ recommended)
• Administrative access to the MySQL server
• Firewall management capabilities

ii. Security Planning

• Identify which IPs need access.
• Determine required privilege levels.
• Plan SSL/TLS setup.
• Consider compliance requirements ("GDPR", "HIPAA", etc.).

2. Database Management Interface

i. Access Database Settings: Navigate to Databases > MySQL in your CloudPanel dashboard ii. Create Remote User: Click 'Add Remote Access' and specify the "IP address" or "hostname". iii. Configure Firewall Rules: CloudPanel configures firewall rules for the specified IP addresses. iv. Build SSL Certificates: Use the built-in SSL certificate generator for encrypted connections.

CloudPanel provides real-time validation of IP addresses and applies security best practices. This graphical approach also reduces configuration errors common with manual command-line setup.

3. MySQL Remote Access Configuration

Step 1: Edit MySQL Configuration Files

The MySQL configuration file controls how the server accepts connections. You will need to adjust the bind-address setting by following these steps.

1. Locate the configuration file. Common locations include:

/etc/mysql/my.cnf

/etc/my.cnf

/etc/mysql/mysql.conf.d/mysqld.cnf

2. Edit the configuration.

Note: This approach limits connections to your private network and provides stronger security. It also lets you check for and comment out the skip-networking directive if present via:

# skip-networking

Step 2: Restart MySQL Service

1. Apply your configuration changes with the following commands:

sudo systemctl restart mysql

sudo systemctl status mysql

2. Verify the service is running and check the error log.

Step 3: Create ‘Remote-based Users’

MySQL treats 'user'@'host' combinations as separate accounts. You cannot adjust 'root'@'localhost' to allow remote access. You must create new user accounts by following the commands given below:

i. Connect to MySQL

mysql -u root -p

ii. Create a user for a 'specific IP'

CREATE USER 'appuser'@'192.168.1.50' IDENTIFIED BY 'SecurePassword123!';

iii. Grant specific privileges (not ALL)

GRANT SELECT, INSERT, UPDATE, DELETE ON myapp_db.* TO 'appuser'@'192.168.1.50';

4. Apply changes

FLUSH PRIVILEGES;

Note: Only grant permissions necessary for the user's function. Never use the 'root user' for remote access. Create dedicated users with limited privileges.

Step 4: Configure Firewall Rules

Configured firewalls are necessary for MySQL security. Follow these steps to set them up:

i. Use UFW (Ubuntu)

1. Allow specific IP access.
2. Use a subnet for port "3306".

ii. Use iptables

1. Allow certain IP addresses.
2. Block other access to the MySQL port.

Note: Cloud firewalls operate on 'OS-level firewalls'. Configure security groups to allow access only from trusted sources using cloud services.

MySQL Remote Access: 4 Advanced Security Configurations

1. SSL/TLS Encryption Setup

Encrypting remote connections protects data in transit. Follow these steps to set up SSL:

i. Build SSL Certificates

Use mysql_ssl_rsa_setup with:

mysql_ssl_rsa_setup --datadir=/var/lib/mysql

ii. Integrate SSL in 'my.cnf'

[mysqld]

ssl-ca = /var/lib/mysql/ca.pem

ssl-cert = /var/lib/mysql/server-cert.pem

ssl-key = /var/lib/mysql/server-key.pem

require_secure_transport = ON

iii. Set Up SSL for Remote Users

a. Use SSL for a specific user via:

ALTER USER 'appuser'@'192.168.1.50' REQUIRE SSL;

b. Use the commands given below for new users:

CREATE USER 'secureuser'@'192.168.1.60'

IDENTIFIED BY 'SecurePassword123!' REQUIRE SSL;

2. SSH Tunneling for Better Security

SSH tunneling adds a layer of security by encrypting the entire connection. Follow the steps given below:

i. Create an SSH tunnel

ssh -L 3306:localhost:3306 user@database-server.com

ii. Connect through the tunnel

mysql -h localhost -P 3306 -u appuser -p

This method helps connect to untrusted networks when extra encryption is necessary.

3. Enhanced Security

CloudPanel provides advanced security features for MySQL remote access. Consider the following:
