Apache refuse to start

I install VSFTPD successfully, reboot the computer.
Apache 2 server refuse to start???? Sudo service apache2 start - does not help
I purge VSFTPD and apache server happy again.
Anyone?

 

Did you get an error message when tried to start Apache?
You can get more details about the problem by running the following command:

systemctl status apache2

or

journalctl -u apache2

It looks like a port issue make sure vsftp confige is okay and using port 21 not 80

 

OK, I will check that of course. A bit surprising though that an FTP program uses port 80 as default.

 

> Ok you can check with this.

 

No port 80 problem. I did disable Ipv6 in config.
FTP still do not work but the apache server did not shut down this time.
Went for dinner 30 minutes. When I came back all my web sites down.
I purged VSFTPD, restart the computer. Apache server is up and running but web sites till down.
I have no other choice than activate my old server. At least it works.
This sickens me to much.

 

'(98)Address already in use' means that there is a port collision. Make sure that there are no other services listening on port 80 and 443. You can check this using the following command:

netstat -tunlp | grep -E ':80\W|:443\W'

and check the log files for more details as suggested.
