I installed MySQL_5.6.26_win32.msi today and encountered some problems. I want to write it down so that I can check it myself later.
The main source of reference for this article: http://blog.csdn.net/libaineu2004/article/details/47061047
Some of the same operations as other bloggers will not be written, but I will write some questions and conclusions that I found in my own practice:
1. Summary of some commands
Installation service and removal service
Installation service: mysqld--install
Delete service: mysqld --remove
Start mysql database and stop mysql database
Start mysql: net start mysql
Stop mysql: net stop mysql
Note: The database can be started and stopped only if the service is installed first
2. The root password problem
At the beginning, according to the blogger’s article, by entering E:\MySQL Server 5.6\bin (the installation directory of the local database), the execution command was executed: mysqladmin -u root password 123456
Then I found that I could enter the database by entering mysql. You can also access the database using mysql -u root -p. Later, using the command "show databases;" I found that the mysql table could not be seen in the database accessed directly using the mysql command. This is probably a root authority problem. The database permissions for directly using the mysql command should be relatively small.
3. Configure environment variables
Later, I found that every time I want to enter the database, I need to go to E:\MySQL Server 5.6\bin ( the installation directory of the local database ) to enter mysql. At this time, I thought of the environment variable path, configured the environment variable, and added path= E: \MySQL Server 5.6\bin; Later, you can directly enter mysql under other paths.
4. Failed to start mysql in cmd
When starting mysql in cmd fails,
a. Need to consider whether the mysql service is up
b. If you get up, check which path you entered MySQL under. If you don’t enter the installation path, whether the environment variables are modified
c. Other situations have not been encountered yet, so please add if you encounter them.
