MySQL version and what the version number is, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain for you in detail, people with this need can come to learn, I hope you can gain something.

For different users, MySQL is divided into two versions:

MySQL Community Server (Community Edition): this version is completely free, but there is no official technical support.

Note: MySQL Cluster is mainly used to set up cluster servers and needs to be used on the basis of community service or enterprise version.

The naming mechanism of MySQL consists of three numbers and a suffix, such as mysql-5.7.20:

The first number "5" is the major version number that describes the format of the file, and all release versions of version 5 have the same folder format.

The second number "7" is the release level, and the major version number and the release level are combined to form the release serial number.

The third number "20" is the version number of this release series, increasing with each new release. You usually choose the latest version that has been released.

In the process of MySQL development, there are multiple release series at the same time, and the maturity of each release series is at different stages.

MySQL 5.7is the newly developed stable (GA) release series, which will perform new functions and is now ready for use.

MySQL 5.6is a relatively stable (GA) release series that is only rereleased for bug fixes and does not add new features that affect stability.

MySQL 5.1 is a stable (product quality) release series that is rereleased only for critical bug fixes and security fixes, without adding important features that affect the stability of the series.

Note: older versions such as MySQL 4.1 will no longer be officially supported. All released versions of MySQL have been tested with rigorous standards to ensure their safe and reliable use. For different operating systems, readers can download the appropriate installation files on the MySQL official download page (http://dev.mysql.com/downloads/).
