In the Linux operating system, MySQL is a popular relational database management system that can be installed and used on different platforms. This article will introduce how to install and configure the MySQL service in the Linux operating system.

sudo apt-get install mysql-server

You can use the following command to install on the CentOS system:

sudo yum install mysql-server

At this point, the system will automatically download and install the MySQL service package.

3. After the installation is complete, you can run the following command again to check the MySQL running status:

sudo service mysql status

2. Configure MySQL

1. After MySQL is installed, some basic configuration needs to be done. You can use the following command to connect to the MySQL service:

mysql -u root -p

After connecting, you need to enter the password of the MySQL root user to enter the MySQL management interface.

2. Generally, we need to create a new MySQL user. You can create it by following the steps below:

CREATE USER 'New user'@'localhost' IDENTIFIED BY 'Password';

Among them, the new user represents the user name you want to create, and the password is the password you set.

b. Authorize the database that new users can access:

In Linux systems, you can use the command line or MySQL GUI tools such as phpMyAdmin to manage MySQL databases.

mysql -u username-p

The username is the MySQL user name you created, and then enter the password to enter the MySQL management interface.

2. Using GUI tools

If you are not familiar with the command line environment, you can also choose to use the MySQL GUI tool to manage the MySQL database. For example, phpMyAdmin is a popular MySQL management interface. You can use the following command to install phpMyAdmin:

sudo apt-get install phpmyadmin

After the installation is complete, you can enter the phpMyAdmin management interface by entering http://localhost/phpmyadmin in a web browser .
