HOWTO Install PHP 7.1, 7.2 and 5.6 as PHP-FPM & FastCGI for ISPConfig 3 on Debian 9

Hi all,
I wrote this thread because i have a big problem at this moment. My ISPConfig have a job queue of 63 tasks to do, but it is freezed for 3 days ATM.

I used the HOWTO : (https://www.howtoforge.com/tutorial/how-to-install-php-5.6-and-7.1-on-debian-9-stretch/) and followed all tasks to have PHP 7.3 available for 2 sites i had in my own (not professionnal sites).

Theses errors are showed at the begin of the log when i start the command :
/usr/local/ispconfig/server/server.sh
I have also stopped ./server in the crontab.

The log is :
22.11.2019-12:01 - WARNING - There is already a lockfile set, but no process running with this pid (17678). Continuing.


PHP Fatal error: Uncaught Error: Call to undefined function mb_detect_encoding() in /usr/local/ispconfig/server/lib/classes/db_mysql.inc.php:523

#7 /usr/local/isp in /usr/local/ispconfig/server/lib/classes/db_mysql.inc.php on line 523

I think there is something in mb_detect_encoding(), but i can't find any solutions.

I have done also the "htf_report.txt", but i think this is only usefull to correct the errors for next :

Arghhh !
I did something but only installing by the apt-get system, with command
apt install php7.2 php7.2-common php7.2-cli php7.2-mysql php7.2-xml php7.2-curl
then i think i must remove it, and use php7.0....................................

/usr/bin/php

Till
Good job for all you made in ISPConfig

 

the result with : php -v

is :

PHP 7.2.24-1+0~20191026.31+debian9~1.gbpbbacde (cli) (built: Oct 26 2019 14:18:28) ( NTS )

then, when i move backward to the PHP7.0 the server
All return to the normal status, grrrrr

TILL,
TY for all you do here

I am under the ground (en français, je suis une grosse merde)

 

If you have monit installed, may be you can monitor your debian 9 default php7.0 like what I am doing in: https://www.howtoforge.com/community/threads/monitor-default-php.83288/

Just change 7.2 in that post to 7.0 or whatever your default php version is supposed to be.

 

TY,
I had just removed the PHP7.2, and the system turn with PHP7.0

All things returning normal

This thread can be closed, if this is possible

 

By the way, compiling php may not be a preferred way anymore since you may need to always recompile each time security issues arise.

You could try another approach if you want multiple php that can be easily updated on your server later: https://www.howtoforge.com/tutorial...3-from-debian-packages-on-debian-8-and-9/amp/
