What should I do if mysql cannot be started in wamp?
Solution to the problem that mysql cannot be started in wamp: 1. Start the MySQL service by setting environment variables; 2. Stop the MySQL service before starting wampserver; 3. Add or modify "innodb_force_recovery" in my.ini =1" and so on.
Recommendation: "mysql video tutorial"
wampserver three services (apache php MySQL) Only the MySQL service cannot be opened.
Here are several solutions:
Since MySQL has been installed before, this installation will not overwrite it. However, to open the MySQL service, you need to open the previous MySQL.
1. You can open the MySQL service by setting the environment variable:
MYSQL_HOME::Add path C:\wamp64\bin\mysql\mysql5.7.23
path: Add: %MYSQL_HOME%/bin
Some computers will report an error: It probably means that wampserver is not working Accept the modified path (go to 2) 
2. Because the MySQL installed before will start the MySQL service, before starting wampserver, stop this service and that’s it!
win R: Run, enter: services.msc, find MySQL, right-click to stop, you can
This time, restart your wampserver or reinstall wampserver, and that’s it! ! ! 3. During this period, I also tried: the following methods, netizens can try them~ (I didn’t succeed anyway~~)
- Open wampserver->mysql-> ;my.ini, add or modify
- innodb_force_recovery = 1, Then restart all services
- Search for the my.ini file in the system, the previous my.ini file will appear, delete it Or rename and then restart wamp;
- In the my.ini file, add: innodb_flush_method=normal and then restart wamp;
- will Change the port number 3306 (this is the default) in the my.ini and config.inc.php files to another 8806 (written by myself, it can be greater than 5000)
