Tutorial for RaspberryPi 4 Installation

FreePBX Installation / Upgrade

I know little about this.

Try fwconsole chown

FreePBX is fussy about PHP version. Check that what you’re running is correct for the FreePBX version.

Look at the Apache error log.

Perhaps

will help.

Otherwise, I hope that a PHP guru will answer.

Hello,

OK, this is what apache error.log says…

[Mon Mar 06 00:00:02.479940 2023] [mpm_prefork:notice] [pid 600] AH00163: Apache/2.4.54 (Debian) configured – resuming normal operations

It seems to be an permission problem, but how to set them corectly?

23

What was the output of
fwconsole chown
given at a root shell prompt?

24

root@FreePBX:/var/log/apache2# fwconsole chown
Taking too long? Customize the chown command, See Sangoma Documentation

25

So there was no error from chown but the permission problem persists. I’m guessing that httpd is not running as the asterisk user. Check with ps whether this is the case. I believe that the User and Group should be set to asterisk in the main httpd.conf file. Perhaps that got overwritten by the same issue that caused index.html in the document root, though I don’t know what that may be.

26

hmm,
i can’t find httpd in ps…

but it looks like that only some of them are running with an own user and the most under root…

27

But apache2 is running as www-data, and that is your HTTP daemon.

28

Check in /etc/apache2/apache2.conf
(For completeness, also /etc/apache2/envvars )

29

www-data seems to be Debian/Ubuntu standard, but it is a bad choice of name as the configuration files and static web contents should not be owned by this user. See the quote in the second reply to permissions - What is the www-data user? - Ask Ubuntu

(Does FreePBX follow this rule?)

Sensitive data should be group, rather than user, protected.

30

The user running asterisk must be the same one as the user serving the /var/www/html directory, it is easier to change the webserver’s owner than FreePBX due to ‘hard-coded-ness’ of one of them

31

Hello,
I checked apache2.conf and there they say to check envars. So I changed the user and group there

envvars - default environment variables for apache2ctl

this won’t be correct after changing uid

unset HOME

for supporting multiple apache2 instances

if [ “${APACHE_CONFDIR##/etc/apache2-}” != “${APACHE_CONFDIR}” ] ; then
SUFFIX=“-${APACHE_CONFDIR##/etc/apache2-}”
else
SUFFIX=
fi

Since there is no sane way to get the parsed apache2 config in scripts, some

settings are defined via environment variables and then used in apache2ctl,

/etc/init.d/apache2, /etc/logrotate.d/apache2, etc.

export APACHE_RUN_USER=asterisk
export APACHE_RUN_GROUP=asterisk

temporary state file location. This might be changed to /run in Wheezy+1

export APACHE_PID_FILE=/var/run/apache2$SUFFIX/apache2.pid
export APACHE_RUN_DIR=/var/run/apache2$SUFFIX
export APACHE_LOCK_DIR=/var/lock/apache2$SUFFIX

Only /var/log/apache2 is handled by /etc/logrotate.d/apache2.

export APACHE_LOG_DIR=/var/log/apache2$SUFFIX

but now, apache2 don’t let me do stop or restart because of the run-dir

root@FreePBX:/usr/sbin# apache2 -k restart
[Tue Mar 07 16:01:49.918940 2023] [core:warn] [pid 155646] AH00111: Config variable ${APACHE_RUN_DIR} is not defined
apache2: Syntax error on line 80 of /etc/apache2/apache2.conf: DefaultRuntimeDir must be a valid directory, absolute or relative to ServerRoot
root@FreePBX:/usr/sbin#

But what should i put in for the run-dir?

32

Hello,

still noone with an idea??
I changed the user with chown of /var/run/apache2 (run dir) to asterisk, but that didn’t change something…
