When you take over the management of a mysql database, you first need to check the maintained mysql database version; when the developer asks you the mysql database version, and you just forget it, then you also need to check the mysql database version at this time.. ............ The following summarizes the method of viewing the mysql database under the Linux platform. Personally, the summary is more comprehensive.
Method 1: When logging in to the database, you can see the version information of the corresponding mysql database, as shown below:
[root@DB-Server ~]# mysql -u root -p
Enter password:

Method 2: Use the system function to check the mysql database version.
