MySQL database installation and configuration practices

Decompress the compressed file to E: \ MySQL-5.1.39-win32.

1. Add E: \ MySQL-5.1.39-win32 \ bin in the path of the system environment variable Note: This is my MySQL installation path)

2. Edit the MySQL run configuration file my. ini. If not, copy the my-medium.ini and name it my. ini

Copy one copy to E: \ MySQL-5.1.39-win32 and C: \ WINDOWS respectively

Edit the my. ini file.

[MySQLd]

Set the MySQL database installation directory

 
 

  
  
basedir=E:/MySQL-5.1.39-win32/ 
 
 

Set the data storage directory of the MySQL database, which must be data or \ xxx \ data

 
 

  
  
datadir=E:/MySQL-5.1.39-win32/data 
 
 

Set the character set of the MySQL server

 
 

  
  
default-character-set=utf8 
 
 

[Client]

Set the character set of the MySQL client

 
 

  
  
default-character-set=gbk 
 
 

Note: The configuration in the split line is optional. You can set it when creating a database.

3. Install the MySQL Service

Enter the directory E: \ myserver \ MS-DOS \ bin from the MySQL-5.0.37-win32 window and run the following command:

 
 

  
  
MySQLd --install MySQL5 --defaults-file=C:\WINDOWS\my.ini 
 
 

MySQL5 is only the name of the service. You can set it by yourself. For example, change it to xiaomai.

That is:

 
 

  
  
MySQLd --install xiaomai --defaults-file=C:\WINDOWS\my.ini 
 
 

4. Start the MySQL database

In the above command window, enter the command: net start MySQL5

In this way, the MySQL service is started.

5. Stop the service

Execute net stop MySQL5.
