[abradabra]

for me on ubunti16.04 also this error.

[ranrinc]

I finally found a simple solutions for this problem.

@abradabra simply create this new ln.
ln -s /lib/systemd/system/php7.0-fpm.service /lib/systemd/system/php-fpm.service

Also to help other with 7.x problem I put my solutions here:
This work on Debian... Ubuntu will have different upgrade procedure.

To upgrade php7.0 fpm to 7.1 or 7.2 (my example is to upgrade to 7.1 fpm)

First of all do fpm upgrade (only for Debian)
Remove apt-get remove --auto-remove php7.0-fpm
apt-get install apt-transport-https lsb-release ca-certificates
wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg
echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" > /etc/apt/sources.list.d/php.list
apt-get update

apt install php7.1-apcu php7.1-bcmath php7.1-cli php7.1-curl php7.1-fpm php7.1-gd php7.1-intl php7.1-mcrypt php7.1-mbstring php7.1-mysql php7.1-soap php7.1-xml php7.1-zip

Move all your config files from your old /etc/php/7.0/fpm/pool.d/ folder to /etc/php/7.1/pool.d/
Go to cd /etc/php/7.0/ and delete all the folder accept for mods-available directory

edit /usr/local/vesta/conf/vesta.conf

Fixed this line to fpm7.1-fpm:
WEB_BACKEND='php7.1-fpm'

Created duplicate content for 7.1:
cp -r /usr/local/vesta/web/edit/server/php7.0-fpm /usr/local/vesta/web/edit/server/php7.1-fpm

Create new link for php7.1-fpm:
ln -s /lib/systemd/system/php7.1-fpm.service /lib/systemd/system/php-fpm.service

Copy web template for php7.1-fpm:
cp -r /usr/local/vesta/data/templates/web/php7.0-fpm /usr/local/vesta/data/templates/web/php7.2-fpm
cp -r /usr/local/vesta/data/templates/web/nginx/php-fpm /usr/local/vesta/data/templates/web/nginx/php7.1-fpm

REBOOT your system...

Thats it.. your vesta should now run the latest php your require to run without a problem.

I hope this help...

@ranrinc, I've found a dirty workaround for this issue, because your approach doesn't work for me at all, unfortunately.
User would just hardcode existing version of php-fpm in /usr/local/vesta/func/domain.sh at line 87

pool=$(find -L /etc/php/7.1/ -type d \( -name "pool.d" -o -name "*fpm.d" \))

Then everything works fine.
@anton-reutov Pay your attension to this issue, please

[StoneLegion]

Having this issue too. Anyone recommend another working control panel?

[devilstars]

Same issue.
Ubuntu 16.04, php 7.1. Had to hardcode it like @Pleskan did.

[Ardakilic]

This also happened to me on Ubuntu 16.04. PHP version got bumped to PHP7.2 from PHP7.1 during updates (I guess php-fpm etc. meta packages were installed) during vesta setup, and this caused this error to appear.

Another alternative is to delete /etc/php/${unused_versions} folders (the pool.d folder actually) without need to alter the .sh code. So the find method only returns one config and it can go on its work. That's what I did anyways

@serghey-rodin Please check this. During the updates, when PHP bumps minor version, old versions' pool.d configurations are left there. It would be hard to dig this without knowledge

[Skamasle]

Vesta actually not suport php upgrades, so if you upgrade php manually you need modify some files to let know vesta your new php version.

So if there are any changes like php7.0 to php7.x you need fix vesta

I try check this to do a automatic fix

[ranrinc]

If only someone can wrote up or help me with the know how, then surely I will create a special pages which can help people to change it. To-Date laravel will require 7.1, so we need to upgrade them. So far I have been trying to edit so many files without a 100% fixed problem regarding this issue.

Again hoping someone can give some guide for this issue.

e,g:
My configuration needed at this moment for ubuntu 16.04.5, running Nginx + phpfpm, mysql or upgrade mariadb (since this wont be working nicely with vesta either)

[dpeca]

Maybe this can help - https://forum.vestacp.com/viewtopic.php?f=41&t=17129 Turorial is based on default nginx+Apache Vesta installation, but has its own solution for nginx-php-fpm only.

[ranrinc]

@dpeca the problem that I'm having is not on nginx setting nor the PHP. Its more on vesta site, once the php being replace then vestacp doesnt work correctly in most of cases error on phpfpm and sometimes kill phpfpm once and for all. Again TPL is not the problem because its simply reedit the nginx conf and you will have the webserver running without a problem. Unless you are not intent to used VestaCP after that creation is OK however if you want to create new domain etc.. then vesta will get many problem and error.

[Skamasle]

I debug this issue

Install vesta in debian 9

Default php version is php 7.0

I upgrade to php 7.2 and yes vesta return errors when add domains and some orthers

The issue isnt from vesta, but vesta will can define than php use to fix this, in any case we can solve it after upgrade
The solution for this issue is easy

Just move ou waste files, so:

After upgrade we get two dirs:

/etc/php/7.0/fpm/pool.d
/etc/php/7.2/fpm/pool.d

Move out /etc/php/7.0/fpm/pool.d

mv /etc/php/7.0/fpm/pool.d /root

And move out /etc/init.d/php7.0-fpm

mv /etc/init.d/php7.0-fpm /root

Now vesta works fine before upgrade to php 7.2

[ranrinc]

@Skamasle I try this method on previous version, however recently the error did appear on my vestaCP and if I'm not mistaken you wont be able to restart PHPFPM and sometime the error appear on your first try and it disappear after the 2nd try.

[Skamasle]

But you clean all old php files and the error persist ?

In my case this works fine, I can add new domains witout problems and of course, you need rebuild vhosts before upgrade and fix all if not you get some error 500 in old domains.

After clean all I not get any error when add or rebuild domain.

[ranrinc]

Here is what I did upon installing the upgrade:
cd /etc/alternatives/
Change the link from 7.0 to 7.1
ln -sf /usr/bin/php7.1 php && ln -sf /usr/share/man/man1/php7.1.1.gz php.1.gz && ln -sf /usr/bin/php-cgi7.1 php-cgi && ln -sf /usr/share/man/man1/php-cgi7.1.1.gz php-cgi.1.gz && ln -sf /usr/lib/cgi-bin/php7.1 php-cgi-bin

Remove php-fpm7.0 and create a new link
ln -sf /usr/sbin/php-fpm7.1 php-fpm

Remove php-fpm7.0 and create a new link
ln -sf /etc/init.d/php-fpm7.1 php-fpm

Replicate /etc/php/7.0/fpm/pool.d to /etc/php/7.1/fpm/pool.d and delete 7.0

And reboot.. please help me add more changes if you think, I'm missing a step.
