To install mysql, follow these steps:
Note that, as shown in the figure, some options are different from the default ones. At the same time, if you re-install mysql, you should first back up the data directory in the mysql Directory, which is the data directory of all users and is very important and cannot be careless.
During the reinstallation, after the data is backed up, uninstall the old mysql and delete the original mysql installation directory.
Select the M option in order to modify the installation directory.
For data security, do not install mysql on the system disk, for example, C: disk.
Note the settings in to change the number of concurrent mysql connections to 1000.
Note that the MYSQL service name is "MYSQL". Do not use other symbols.
The entered password is the MYSQL administrator Root password.
So far, Mysql is successfully installed.
