[SOLVED]Lost ISPConfig Panel AFTER "Update the ISPConfig Perfect Server from Debian 11 to Debian 12"

Hello,
Thank you in advance to read me. Any help will appreciated to solve this access problem to ISPConfig Panel.

1/ INTRODUCTION :
TWO servers are involved : master ( with ispconfig panel included and DNS service ) and slave ( DNS service only ).
The 2 servers should "only" provide DNS services via BIND.
Before start the upgrade the ISPConfig web panel was running on port 81. ( not 8081 )

2/ WHAT I HAVE DONE BEFORE THE PROBLEM APPEARS :
ON THE SLAVE SERVER : i followed this guide "Update the ISPConfig Perfect Server from Debian 11 to Debian 12" to upgrade ISPConfig 3.2.11 which was on debian 11
( the first installation was from 2017 probably on debian 9. All the upgrades since those period were fine without problem.)

ON THE MASTER SERVER : same process than on the SLAVE.

3/ WHAT i OBSERVE AFTER upgrade :
THE ACCESS to the ISPConfig panel was not possible. I was only able to acces to apache default page !

4/ WHAT i HAVE DONE on the server to try to solve the problem :
a/ Since the ispconfig service was running on the 81 port before upgrade when the default is 8081, i have made modification to make apache listen on 8081.

b/ On the master server into file /etc/apache2/apache2.conf i find this 2 lines :

line 1 : # Include the virtual host configurations:
line 2 : IncludeOptional sites-enabled/*.conf

On the master server into file /etc/apache2/apache2.conf.dpkg-old :
line 1 : # Include the virtual host configurations:
line 2 : IncludeOptional sites-enabled/

Since file with ".vhost" (the one associated to ISPConfig panel i think ?!? ) exists i have replace
line 2 : IncludeOptional sites-enabled/*.conf
BY
line 2 : IncludeOptional sites-enabled/ into /etc/apache2/apache2.conf/ AND restart apache2.

I have also suppress the LISTEN line into several "conf" and "vhost" files since it was generate appache2 error logs.

Into "/etc/apache2/sites-available " : the following files are availables :

Code:

000-default.conf
acme.conf
apps.vhost
default-ssl.conf
ispconfig.conf
ispconfig.vhost

THE FACT THAT 2 files with ISPCONFIG name exist let me wonder if it is "normal" or not in my case ?

The result of the command : journalctl -xeu apache2.service

Code:

RESULT :
░░ L'unité (unit) apache2.service a commencé à recharger sa configuration.

5/ WHERE i am at the moment and ask for helps or idea via this post :

access via port 8081 : with the DNS name
RESULT :
Forbidden
You don't have permission to access this resource.


access via port 80 : with the DNS name
RESULT :
default apache page.

##### LET'S ENCRYPT #####
Certbot is installed in /usr/bin/letsencrypt

 

Actual default port for ISPConfig is 8080, so I think the fault could be because two ports 8081 existed i.e. one for ispconfig and another for apps vhost?

Did you run apache2ctl -t to check your apache2 config?

 

Hi ThOm, Hi ahrasis,

Thank you for your reply. I am sorry for the presentation into my posting. I have no excuse for that other that the fact i am not fluent this this sort of publication tool. I am going to do my best and ask you to forgive me if i do other mistakes.

-1- I reply to ThOm : Yes I can share /etc/apache2/apache2.conf . Here it is :

Code:

# This is the main Apache server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.4/ for detailed information about
# the directives and /usr/share/doc/apache2/README.Debian about Debian specific
# hints.
#
#
# Summary of how the Apache 2 configuration works in Debian:
# The Apache 2 web server configuration in Debian is quite different to
# upstream's suggested way to configure the web server. This is because Debian's
# default Apache2 installation attempts to make adding and removing modules,
# virtual hosts, and extra configuration directives as flexible as possible, in
# order to make automating the changes and administering the server as easy as
# possible.

# It is split into several files forming the configuration hierarchy outlined
# below, all located in the /etc/apache2/ directory:
#
#       /etc/apache2/
#       |-- apache2.conf
#       |       `--  ports.conf
#       |-- mods-enabled
#       |       |-- *.load
#       |       `-- *.conf
#       |-- conf-enabled
#       |       `-- *.conf
#       `-- sites-enabled
#               `-- *.conf
#
#
# * apache2.conf is the main configuration file (this file). It puts the pieces
#   together by including all remaining configuration files when starting up the
#   web server.
#
# * ports.conf is always included from the main configuration file. It is
#   supposed to determine listening ports for incoming connections which can be
#   customized anytime.
#
# * Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/
#   directories contain particular configuration snippets which manage modules,
#   global configuration fragments, or virtual host configurations,
#   respectively.
#
#   They are activated by symlinking available configuration files from their
#   respective *-available/ counterparts. These should be managed by using our
#   helpers a2enmod/a2dismod, a2ensite/a2dissite and a2enconf/a2disconf. See
#   their respective man pages for detailed information.
#
# * The binary is called apache2. Due to the use of environment variables, in
#   the default configuration, apache2 needs to be started/stopped with
#   /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not
#   work with the default configuration.


# Global configuration
#

#
# ServerRoot: The top of the directory tree under which the server's

-2- Now i reply to aharis : The result of the following command : " apache2ctl -t " is :

Code:

AH00548: NameVirtualHost has no effect and will be removed in the next release /etc/apache2/sites-enabled/000-ispconfig.vhost:7
Syntax OK

-3- What i have try between my fisrt post and this reply :
I have tried to isolate an eventual SSL problem or misconfiguration. Therefore i have modify SSLEngine from ON to OFF into :
"/etc/apache2/sites-available/apps.vhost"
AND
"/etc/apache2/sites-available/ispconfig.vhost"
## SSLEngine On
##
SSLEngine Off

-4- Concerning the ports modification here is the "/etc/apache2/ports.conf " details :

Code:

Listen 80
<IfModule ssl_module>
        Listen 443
        Listen 8081
</IfModule>

<IfModule mod_gnutls.c>
        Listen 443
        Listen 8081
</IfModule>

Well during to ispconfig "force" update i suppose that something may going wrong cause of me ?!?
Nethertheless thank you in advance for your lights if you get any.
Regards.

In these two files, on the top, what port each is listening to?

 

Hi till, Hi ahrasis, Hi ThOm,

Thank to all off you the problem has been solved.

I am going to give details to maybe help other in similar case :

-1- Thanks to ThOm question : " you may have to verify that the " /etc/apache2/apache2.conf " ( post 2 )
i have verify that those file include a line
" IncludeOptional sites-enabled/ "
and NOT a line like " IncludeOptional sites-enabled/*.conf "
in case NOT the files ispconfig.vhost and apps.vhost will NOT be loaded by appache2 server i guess since the extention ".vhost" is different from extention ".conf".


-2- Thank to ahrasis, i was wondering concerning the port configuration.
ahrasis tall me than appache2 should NOT run with apps and ispconfig file configured on the SAME listening port. ( post 3 )

Since appache2 stop and start without problem i have been perplex but his remark was 100% right.
In fact apache2 was stop and start fine cause i had added the 8081 listener into "/etc/apache2/ports.conf " and SUPPRESS the Listen command into "ispconfig.vhost" and "apps.vhost" files. A big mistakes from me !

-3- Thank to till i have made the link between ahrasis remarks and clear till explanations of the ports attribution.

As consequence i have do the following to solve the ( my personel ) problem since till has 100% right on the fact that the default ports have been modified during the life of this server ( 2017 to now ) by administrators and, i had made a wrong assumption concerning the ports attribution of ISPConfig.


As conclusion i have modified the following files has details below :
-A-

/etc/apache2/sites-available/apps.vhost

Code:

######################################################
# This virtual host contains the configuration
# for the ISPConfig apps vhost
######################################################
Listen 8081
<VirtualHost _default_:8081>
.....
keep the rest intact 

-B-
/etc/apache2/sites-available/ispconfig.vhost

Code:

######################################################
# This virtual host contains the configuration
# for the ISPConfig controlpanel
######################################################
Listen 8080
<VirtualHost _default_:8080>
.....
keep the rest intact

-C-
/etc/apache2/ports.conf

Code:

# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default.conf

Listen 80
<IfModule ssl_module>
        Listen 443
</IfModule>

<IfModule mod_gnutls.c>
        Listen 443
</IfModule>

-D- after those modifications i have launched the following command:
/etc/init.d/apache2 restart


After that modifications "ALL has been SOLVED".
I am now able to acces the ISPCONFIG PANEL via http://MyDNS-hostname:8080


CONCLUSION :

Thank you VERY much to all of you for this smart and efficient assistance.
Best Regards

Elvé
