MySQL is a commonly used relational database management system that is widely used in many scenarios such as the Internet field and enterprise informatization. However, for many beginners, opening MySQL can be a bit difficult. Below, we will use Windows and Linux systems as examples to introduce how to open MySQL.

1. Open MySQL under Windows system

Under Windows system, MySQL can be opened in the following ways:

  1. Use MySQL client tool

If MySQL has been installed and configured on the Windows system, you can directly use the MySQL client tool to open MySQL. Currently, the more mainstream client tools include MySQL Workbench and Navicat for MySQL.

Below, we take MySQL Workbench as an example:

First, open MySQL Workbench and select the MySQL instance that needs to be connected on the start page (if the connection information has been set, you can directly Click to connect). By filling in information such as user name and password, and connecting to the MySQL instance, you can manage and operate MySQL through Workbench.

  1. Use command line tools

In addition, using command line tools to open MySQL is also a common way. The specific steps are as follows:

1) Click "Start", open "Run" (or press the Win R shortcut key), enter "cmd" in the pop-up window, and then click "OK" to open the command line interface.

2) Enter the following command to enter the "bin" folder in the MySQL installation directory:

cd /d "C:Program FilesMySQLMySQL Server 8.0in"

Note: The above command needs to be modified according to your actual installation path.

3) Enter the following command to log in to MySQL:

mysql -u root -p

Note: In the above command, "-u" means specifying the user name, and "-p" means prompting for a password. After inputting, you need to press the Enter key to confirm.

4) After successful login, you can operate MySQL in the command line interface.

2. Open MySQL under Linux system

Under Linux system, opening MySQL includes two steps: starting the MySQL service and logging in to the MySQL server. Below, we take the CentOS 7 system as an example to introduce the specific operation steps:

  1. Start the MySQL service

In CentOS 7, you can start the MySQL service through the following command:

systemctl start mysqld.service

If you need to automatically start MySQL when the system starts, you can use the following command:

systemctl enable mysqld.service
  1. Log in to the MySQL server

After starting the MySQL service, You can use the following command to log in to the MySQL server:

mysql -u root -p

Among them, the "-u" parameter specifies the user name, and the "-p" parameter prompts for a password. If you enter the correct password, you will be logged in to the MySQL server.

In addition to using command line tools to log in to the MySQL server, you can also log in and operate through other client tools, such as Navicat for MySQL.
