XAMPP Apache和MySQL Server无法启动

Question

aI have the problem that both services won't start. On both, I get the Message

Error: MySQL shutdown unexpectedly. (The same with apache).

I already changed the ports of the apache server from 80 to 8080 and 443 to 4433, and also to others to check, that doesn't help.

I tried some solutions on similar posts here, like deleting the ibdata1-file in the mysql-folder, but none of these seem to work. I even don't think these might solve it, because both services are affected.

Another idea I had was that I had not enough rights on the pc to run these services, but I am logged in as administrator and I also have a postgres-service running which I am able to stop and restart.

I am using Windows 10, but had XAMPP running on it before.

httpd.exe: Syntax error on line 37 of E:/Data/Xampp/apache/conf/httpd.conf: ServerRoot must be a valid directory

The File errmsg.sys exists though.

Answer 1

I found another solution that worked for me! If anyone has that problem, try to start apache via batch file "apache_start" located in xampp-directory. that gave me the error:

ServerRoot must be a valid directory

This again could be solved by running the "setup_xampp" batch file, located in the same directory. After completion, apache & mysql were running again.
