php - Apache shutdown unexpectedly

Question

I am using XAMPPS to host PHP files from my machine. I have recently installed XAMPPs but I am unable to start Apache service as port 80 is in use by PID 4 - NT Kernel & System.

I know by using a different port (such as port 8080 etc change in httpd.conf) will get to a workaround for this issue. However I need port 80 to be released by PID 4 process and allocated to Apache service. I have done that in the past but have forgotten the resolution steps over the time. Please help me fix it

This is the error I am encountering while starting Apache

`11:19:52 AM  [Apache]  Error: Apache shutdown unexpectedly.`
`11:19:52 AM  [Apache]  This may be due to a blocked port, missing dependencies,` 
`11:19:52 AM  [Apache]  improper privileges, a crash, or a shutdown by another method.`

Answer 1

on your XAMPP control panel, next to apache, select the "Config" option and select the first file (httpd.conf):

there, look for the "listen" line (you may use the find tool in the notepad) and there must be a line stating "Listen 80". Note: there are other lines with "listen" on them but they should be commented (start with a #), the one you need to change is the one saying exactly "listen 80". Now change it to "Listen 1337".

Start apache now.

If the error subsists, it's because there's another port that's already in use. So, select the config option again (next to apache in your xampp control panel) and select the second option this time (httpd-ssl.conf):

there, look for the line "Listen 443" and change it to "Listen 7331".

Start apache, it should be working now.
