Apache2 does not restart

I don't know how to do it, I ask you for some patience, could you explain me how to restore? should i just delete the bak files?

 

means copy the .bak files to the original files.

 

if I understand correctly I have to do the following procedure: open the ispserver.key-201226233709.bak file copy the content and paste it in the ispserver.key file then delete ispserver.key-201226233709.bak consequently do the same thing with the other file bak?

 

Well, maybe it can be done that way, but command cp would be easier.

Code:

cp ispserver.key-201226233709.bak  ispserver.key

How did you manage the make those .bak files?

 

following this guide https://www.howtoforge.com/tutorial/securing-ispconfig-3-with-a-free-lets-encrypt-ssl-certificate/

 

I tried to perform the procedure you indicated but it does not make me restore the files maybe I'm wrong in something

Code:

root@server:/usr/local/ispconfig/interface/ssl# ls
empty.dir      ispserver.crt-201226233658.bak  ispserver.key                   ispserver.key.secure
ispserver.crt  ispserver.csr                   ispserver.key-201226233709.bak
root@server:/usr/local/ispconfig/interface/ssl# cp ispserver.key-201226233709.bak  ispserver.key
cp: cannot stat 'ispserver.key-201226233709.bak': No such file or directory
root@server:/usr/local/ispconfig/interface/ssl# cp ispserver.crt-201226233658.bak  ispserver.crt
cp: cannot stat 'ispserver.crt-201226233658.bak': No such file or directory
root@server:/usr/local/ispconfig/interface/ssl#

 

if you notice in post 26 that's just what I did ..

 

do you think that uninstalling and reinstalling ispconfig alone would be enough to solve the problem? or do I have to redo the whole procedure of the guide https://www.howtoforge.com/perfect-server-debian-10-buster-apache-bind-dovecot-ispconfig-3-1/?

 

Is there a difference between those two alternatives? I mean, if you uninstall ISPConfig, the installing is redoing that perfect server guide.
Anyway, I believe the cp command fails because there are invisible characters in the filename you copypasted. Notice the two spaces after the filename. Try writing the filename yourself.

 

I wrote manually but nothing changes

 

Then try this to see if the filenames in that directory have invisible characters:

Code:

ls -lh *.bak | od -c

You do not need to paste the output here, just check yourself if filenames have extra characters. If they have, you can use wildcards when copying them to avoid needing to type those maybe strange characters.

 

I paste anyway because I would like your confirmation that it seems that there are no extra characters

Code:

root@server:/usr/local/ispconfig/interface/ssl# ls -lh *.bak | od -c

Show

Code:

ls -lh *.bak

Looks like the files are symbolic links to somewhere else.
Do the files they point to exist?

 

you mean this?

Code:

root@server:~# ls -lh /usr/local/ispconfig/interface/ssl/ispserver.*
lrwxrwxrwx 1 root root   58 Dec 26 23:39 /usr/local/ispconfig/interface/ssl/ispserver.crt -> /etc/letsencrypt/live/server.tradingforum.it/fullchain.pem

-rwxr-x--- 1 root root 3.3K Dec 26 18:20 /usr/local/ispconfig/interface/ssl/ispserver.key.secure

 

I managed to enter the ispconfig panel, do I try to follow the guide again? https://www.howtoforge.com/tutorial/securing-ispconfig-3-with-a-free-lets-encrypt-ssl-certificate/

 

now I find myself with these files I delete the back right?

Code:

root@server:/usr/local/ispconfig/interface/ssl# ls
empty.dir                       ispserver.key
ispserver.crt                   ispserver.key-201226233709.bak
ispserver.crt-201226233658.bak  ispserver.key.secure
ispserver.csr
root@server:/usr/local/ispconfig/interface/ssl#

 

in the end after a few tries following the guide https://www.howtoforge.com/tutorial/securing-ispconfig-3-with-a-free-lets-encrypt-ssl-certificate/ I solved thanks to all ..
