My wamp, why does mysql fail to start normally after running my wamp for a period of time? mysql cannot start, so it must be uninstalled and installed again, what is the reason? yesterday it was still good, and today it went wrong. there was a yellow warning that mysql could not run, and there was nothing wrong with it. I used to see it once before, after running for a period of time, why cannot mysql be started properly?

Yesterday was still good, and there was a problem running today. there was a yellow warning that mysql could not run, and everything else was okay.
I used to see it once. after running for a period of time, mysql cannot run normally, so I try to install it again. I have data in mysql, so I don't want to install it. that man, let me know the reason. thank you...

------ Solution --------------------
Check if other programs occupy the MYSQL port.

Netstat-a-n-B

If you haven't changed the mysql port, check whether 3306 is occupied.

Passing!

I also experienced that situation, but now it's okay, because I installed a mysql independently and gave Port 3306 to the station.
Let me tell you a way to copy everything in the following path: wamp-> mysql-> data->, after the wamp is re-installed, copy the information you have taken to the new data folder. you can simply copy it to the tables in your database.

I have never encountered any of your symptoms, but I encountered an error when exporting all the information in the database. if it is not easy to use, I will try again on the WAMP, if it is still not easy to use, it may be the port. we cannot afford it because we have installed MYSQL, but the group test table has not been changed and the file is not completely deleted, so it is still not easy to use, you can use it after redoing the system!
