How to check the version of mysql

MySQL is a software used to manage relational databases. It is one of the most popular open source databases in the world. When using the MySQL database, we often need to check its version information to determine the functions and features supported by this version. This article will introduce how to check the MySQL version.

1. Check the MySQL version through the command line

We can check the MySQL version information through the MySQL command line interface. First, we need to log in to the MySQL server and open the command line interface. We can use the following command to log in to the MySQL server:

mysql -u root -p

where root is the super administrator account name of the MySQL database. After entering this command, we will be prompted to enter the root password.

After successfully logging in, we can enter the following command to view the MySQL version information:

SELECT VERSION();

This command will display the version number of the current MySQL server.

2. Check the MySQL version through the MySQL client tool

In addition to the command line method, we can also check the MySQL version information through the MySQL client tool. MySQL client tools include:

1. MySQL Workbench: the database management software officially provided by MySQL.
2. Navicat for MySQL: A commercial MySQL database management software.
3. phpMyAdmin: An open source MySQL database management software.

Let's take MySQL Workbench as an example. After opening MySQL Workbench, we can select the "Server" menu and then select the "Server Status" option to view the MySQL version information.

In the "Server Information" tab page, we can see the version information of the MySQL server.

3. Check the MySQL version through the MySQL configuration file

The version information of the MySQL server can also be found in the MySQL configuration file. In Linux systems, the MySQL configuration file is usually placed in the /etc/my.cnf or /etc/mysql/my.cnf file.

In the configuration file, we can find the following configuration information:

[mysqld]
.
.
.
version = xxxxxxxxxx

Among them, the version parameter indicates the version number of the MySQL server. If you can't find such configuration information, you can try searching for "version" in the entire configuration file.

To sum up, through the above three methods, we can easily check the MySQL version. Different methods have their own advantages and disadvantages, and you can choose the most appropriate method according to the actual situation.
