Are you working with an EC2 instance using Amazon Linux 2023 and need MySQL? Unlike previous versions, MySQL no longer comes preinstalled, and the installation process can be somewhat confusing. But don't worry! Here is a step-by-step guide to install it without complications and configure it properly.
1. Download MySQL RPM file
The first step is to download the file from the MySQL repository. This will allow you to access the most recent versions:
sudo wget https://dev.mysql.com/get/mysql80-community-release-el9-1.noarch.rpm
2. Install the RPM file
This file will configure the repository needed for the installation:
sudo dnf install mysql80-community-release-el9-1.noarch.rpm -y
3. Import the MySQL public key
To avoid problems with packet authentication, import the MySQL GPG key:
sudo rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2023
4. Install MySQL according to your needs
MySQL client only:
sudo dnf install mysql-community-client -y
MySQL Server (includes client):
sudo dnf install mysql-community-server -y
5. Configure MySQL server
Start the service and make sure it boots automatically with the system:
sudo systemctl start mysqld sudo systemctl enable mysqld
Verify that the service is working:
sudo systemctl status mysqld
? Here's an example of what the service status should look like:
6. MySQL initial setup
Before using MySQL, you need to perform an initial configuration. First, find the temporary password generated during installation:
sudo grep 'temporary password' /var/log/mysqld.log
? An example of the result is shown below:
Next, run the initial configuration script:
sudo mysql_secure_installation
Recommendations when setting the password
1. Meets security requirements:
- At least one uppercase and one lowercase letter.
- At least one number.
- At least one special symbol (.!@#$%^&*()).
If you don't meet these criteria, you will see an error like this:
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements.
2. Evaluate the security level:
MySQL will show you a percentage that indicates how secure your password is. A level of 100% indicates maximum security.
3. Adjust validation policy (optional):
If you prefer less strict passwords, you can modify the validation policy in the /etc/my.cnf file or through commands within MySQL.
What does the mysql_secure_installation script do?
This script guides you to make key adjustments to your security settings:
- Change root password: Use a strong password following the recommendations above.
- Disable anonymous users: This prevents unauthorized access.
- Delete test database: Protect your system by deleting default data.
- Restrict remote access: Ensures that it can only be accessed from the local machine.
