Record the problems encountered in your installation process, and I hope it will be useful to you.

1. Download (it is officially recommended to download the installation version, but the unzipped version is more convenient), download address:

2. To decompress, we need to add one more step:

(1) create a file named my.ini, and add: the data folder was built before, but the subsequent installation reported an error, which is a warning.

3. Modify the my.ini file:

[mysql] # set mysql client default character set default-character-set=utf8 [mysqld] # set port 3306 port = 330mm set mysql installation directory basedir = D:\\ Program Files\\ mysql\\ # set mysql database data storage directory datadir = D:\\ Program Files\\ mysql\\ data# the character set used by the max_connections=20# server defaults to 8-bit encoded latin1 Default storage engine default-storage-engine=INNODB# creation mode sql_mode = NO_ENGINE_SUBSTITUTION that the character set character-set-server=utf8# will use when creating a new table STRICT_TRANS_TABLES

Special attention should be paid to:

(1) D:\\ Program Files\\ mysql\\ data this directory must be "\", do not make it "\", or you will report an error, or you can use "/".

(2) Mysq installation directory and data storage directory must be modified for your own directory, unless you set the same directory as above.

4. Configure the environment variables of mysql:

Click Path to add:

5. Run cmd as an administrator and do the following:

(1) change to the bin directory of mysql

(2) execute the mysqld-- initialize command, and a new directory data will be generated. If you look at the .err file, you can see the random password generated by the root user.

(3) execute the mysqld-- install command to install the mysqld service

(4) execute net start mysql command to start mysql service

(5) execute the command mysql-u root-p, connect to the mysql database, and enter the password randomly generated above

(6) perform the following sql to reset the root password:

Mysql > alter user 'root'@'localhost' identified with mysql_native_password by' New password'

Tips:

Mysqld-initialize-insecure automatically generates root users without passwords; mysqld-initialize automatically generates root users with random passwords; mysqld-remove removes its own mysqld service; net stop mysql command to stop mysql service if an error is reported, empty the data folder, it is best to delete the data file and re-execute the remove--initialize--install--start (these are not commands) process
