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:
- MySQL Workbench: the database management software officially provided by MySQL.
- Navicat for MySQL: A commercial MySQL database management software.
- 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.
The above is the detailed content of How to check the version of mysql. For more information, please follow other related articles on the PHP Chinese website!

GTID (Global Transaction Identifier) ??solves the complexity of replication and failover in MySQL databases by assigning a unique identity to each transaction. 1. It simplifies replication management, automatically handles log files and locations, allowing slave servers to request transactions based on the last executed GTID. 2. Ensure consistency across servers, ensure that each transaction is applied only once on each server, and avoid data inconsistency. 3. Improve troubleshooting efficiency. GTID includes server UUID and serial number, which is convenient for tracking transaction flow and accurately locate problems. These three core advantages make MySQL replication more robust and easy to manage, significantly improving system reliability and data integrity.

MySQL main library failover mainly includes four steps. 1. Fault detection: Regularly check the main library process, connection status and simple query to determine whether it is downtime, set up a retry mechanism to avoid misjudgment, and can use tools such as MHA, Orchestrator or Keepalived to assist in detection; 2. Select the new main library: select the most suitable slave library to replace it according to the data synchronization progress (Seconds_Behind_Master), binlog data integrity, network delay and load conditions, and perform data compensation or manual intervention if necessary; 3. Switch topology: Point other slave libraries to the new master library, execute RESETMASTER or enable GTID, update the VIP, DNS or proxy configuration to

The steps to connect to the MySQL database are as follows: 1. Use the basic command format mysql-u username-p-h host address to connect, enter the username and password to log in; 2. If you need to directly enter the specified database, you can add the database name after the command, such as mysql-uroot-pmyproject; 3. If the port is not the default 3306, you need to add the -P parameter to specify the port number, such as mysql-uroot-p-h192.168.1.100-P3307; In addition, if you encounter a password error, you can re-enter it. If the connection fails, check the network, firewall or permission settings. If the client is missing, you can install mysql-client on Linux through the package manager. Master these commands

InnoDB is MySQL's default storage engine because it outperforms other engines such as MyISAM in terms of reliability, concurrency performance and crash recovery. 1. It supports transaction processing, follows ACID principles, ensures data integrity, and is suitable for key data scenarios such as financial records or user accounts; 2. It adopts row-level locks instead of table-level locks to improve performance and throughput in high concurrent write environments; 3. It has a crash recovery mechanism and automatic repair function, and supports foreign key constraints to ensure data consistency and reference integrity, and prevent isolated records and data inconsistencies.

MySQL's default transaction isolation level is RepeatableRead, which prevents dirty reads and non-repeatable reads through MVCC and gap locks, and avoids phantom reading in most cases; other major levels include read uncommitted (ReadUncommitted), allowing dirty reads but the fastest performance, 1. Read Committed (ReadCommitted) ensures that the submitted data is read but may encounter non-repeatable reads and phantom readings, 2. RepeatableRead default level ensures that multiple reads within the transaction are consistent, 3. Serialization (Serializable) the highest level, prevents other transactions from modifying data through locks, ensuring data integrity but sacrificing performance;

MySQL transactions follow ACID characteristics to ensure the reliability and consistency of database transactions. First, atomicity ensures that transactions are executed as an indivisible whole, either all succeed or all fail to roll back. For example, withdrawals and deposits must be completed or not occur at the same time in the transfer operation; second, consistency ensures that transactions transition the database from one valid state to another, and maintains the correct data logic through mechanisms such as constraints and triggers; third, isolation controls the visibility of multiple transactions when concurrent execution, prevents dirty reading, non-repeatable reading and fantasy reading. MySQL supports ReadUncommitted and ReadCommi.

To add MySQL's bin directory to the system PATH, it needs to be configured according to the different operating systems. 1. Windows system: Find the bin folder in the MySQL installation directory (the default path is usually C:\ProgramFiles\MySQL\MySQLServerX.X\bin), right-click "This Computer" → "Properties" → "Advanced System Settings" → "Environment Variables", select Path in "System Variables" and edit it, add the MySQLbin path, save it and restart the command prompt and enter mysql--version verification; 2.macOS and Linux systems: Bash users edit ~/.bashrc or ~/.bash_
