This article will explain in detail why mysql5.5 can not be installed, the editor thinks it is very practical, so share it for you to do a reference, I hope you can get something after reading this article.

The solution to the failure of mysql5.5 installation: first uninstall MySQL; and then delete the installation directory and data storage directory; then query mysql in the registry regedit and delete them all; finally, download and install again.

The front of the installation is normal, and there is always a problem in the last step. The last few times did not respond to the last step, there is a way on the Internet is to change the default service name "MySQL" when installing MySQl. But I've tried this method, and it didn't work out several times.

In this case, I used the second method.

1. Uninstall MySQL

two。 Delete the installation directory and data storage directory, that is, C:\ Program Files\ MySQL

3. Query mysql in the registry (regedit) and delete all

Start cmd in the registry and enter regedit

Under HKEY_LOCAL_MACHINE\ SYSTEM

1.Eventlog\ Application\ MySQL,

2.CurrentSet001Services\ Eventlog\ Application\ MySQL,

3.ControlSet002\ Services\ Eventlog\ Application\ MySQL,

4.CurrentControl001t\ Services\ MYSQL

5.CurrentControl002\ Services\ MYSQL

6.CurrentControlSetServices\ Eventlog\ Application\ MySQL,

And then download it again.

(even deleted the relevant hidden files)

However, I am not so lucky, to the last step, there is a problem, the third option: startservice is a red cross state, at this time my heart ten thousand grass mud horses galloping past. Because up to now I have pretended it no less than ten times.

So she asked du Niang again, she said to turn off the security software on the computer, I obediently turned off all

Security guards and antivirus software, but also forced me to close the firewall, and then restart (has been restarted N times before … Execute the second method mentioned above before restarting), with the mentality of asking the upperclassman for help, the installation was successful. Well. In fact, I still don't know what the problem is at the end of the day.

By the way, why did I reinstall? the last installation process was smooth, and I remember the password very clearly, but when I typed it again later, it showed the wrong password. I guarantee that I have never changed it, so I don't know how the password is wrong.

About why mysql5.5 can not be installed to share here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
