How to solve the wamp5 mysql service can not start the problem, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can gain something.

Recently, due to the needs of the company, I began to learn. It feels a little simple. Maybe it's a bit of a basis for java. But it's not deep enough. It was just a simple try, and there were problems when installing the tools. I would like to sum up three points. I welcome experts to supplement and learn together.

Now let's talk about why this problem arises:

(1) it has been installed before, because mysql has been integrated into wamp, so there is no need to install it yourself, just install mysql's client tools and uninstall the previously installed mysql. (that's why I am) A friendly reminder: remember to back up useful data before uninstalling mysql.

(2) cannot find the php_mysql.dll file, just reconfigure the path of the file. Configure it in php.ini, find extension_dir= "" and write in the correct path (by default, the path of php_mysql.dll is under D:/wamp/php/ext/, and I install it on disk D).

(3) change the configuration file my.ini of mysql

Change the engine, put

Default-storage-engine=INNODB

Change to

Default-storage-engine=MyISAM
