XAMPP setup - MySQL not working

0
votes

I'm trying to get XAMPP working on Win7/64 for testing Wordpress themes.

I was originally getting a problem with Apache trying to access Port 80 but I was told to change the config file to port 81 which I have done and now Apache is running and localhost:81 shows the XAMPP control panel fine.

However, now MySQL is not working at all. Before I changed the config file, I think it was, but Apache was not running so I still couldn't access localhost at all.

In Windows Event Viewer, I am getting this Error report on the MySQL:

Fatal error: Can't open and lock privilege tables: Can't find file: 'host' (errno: 2)

In XAMPP's console I am currently getting this:

Is there a config file I need to change to match the Apache file? There's nothing obvious I can see.

Many thanks in advance.

that port 80 issue might have been that skype is running (it uses port 80). for mysql i cant help you, the default port is 3306, run a port scanner to check open ports on your system. or read the /xampp/mysql/data/mysql_error.log. or maybe you have another webserver with mysql running (check your services) - x4rf41
Wasn't Skype, I don't have it. Will update question to include text of the error log. - sanjaypoyzer
You can run netstat -aon, get PID and lookup the app with that identifier. - Grigorii Chudnov
Ok thanks, I've done that and found the Image Name in question is just called "System". Sounds a bit ominous. What does this mean? - sanjaypoyzer

Ended up solving the problem by uninstalling XAMPP, reinstalling it again and then changing the port that Apache uses from 80 to 8080.

Hey I just did this and it worked:

  1. exit Xampp server
  2. go to your C:\xampp\mysql\data directory
  3. delete the ibdata1 file
  4. restart xampp server
