[SOLVED]Error in executing php-fpm on buildt php-5.6 on debian 9

This is error
[Thu May 17 23:30:54.290846 2018] [proxy:error] [pid 8941] (2)No such file or directory: AH02454: FCGI: attempt to connect to Unix domain socket /var/lib/php7.0-fpm/web6.sock (*) failed

Any idea?

 

I used this guide to install multiple php versions
https://www.howtoforge.com/tutorial/how-to-install-php-7-on-debian/
on a
https://www.howtoforge.com/tutorial...-9-stretch-apache-bind-dovecot-ispconfig-3-1/
on DigitalOcean VPS

 

Might be a mix up where fpm-config for the wrong php version (doesn't) exist.
Set fastcgi or other php mode, check for remaining config in fpm pool.d and delete it if it exists.
restart your fpm daemons and enable php-fpm for that web again. It should work, even if you switch versions.
If not, check your setup - like did you really change the default www.conf listening port for the new php-version...

 

I used this guide to install multiple php versions
https://www.howtoforge.com/tutorial/how-to-install-php-7-on-debian/
In this guide the ports change in various version

specifically in 5.6 is 8997

where did I find www.conf?

 

That output give me what I'm expecting:

Code:

PHP 5.6.36 (cli) (built: Apr 27 2018 10:24:12)
Copyright (c) 1997-2016 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies
    with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2016, by Zend Technologies

I confirm it work with fast-cgi but would be great if it work with both.

I also suggest to put in the Howtoforge guide the --with-gd parameter, it's really needed and I had to recompile php.
Optional --with-mysql=shared would also be great for those who need to port old webs.

 

netstat output is empty. No output. and the port is the same as the configured one.

 

Done

Code:

Enable the service and reload systemd:

systemctl enable php-5.6-fpm.service
systemctl daemon-reload

Finally, start PHP-FPM.

systemctl start php-5.6-fpm.service

netstat didn't output anything

if I execute the netstat command on the 8998 port (is the port for php 7.2) it return

Code:

tcp        0      0 127.0.0.1:8998          0.0.0.0:*               LISTEN      808/php-fpm: master 

Seems the service didn't run
There's a log where i can inspect?

 

usually not - but I still assume an issue with the default [www] fpm-service. without it configured properly, the service won't start and ISPConfig gets confused a bit.
The port numbers are not used @StefanoBertoli , they just need to be unused.

Please double check the paths within and of /opt/php-5.6/etc/php-fpm.conf to be correct, aswell as the other settings.
What happens if you run

Code:

$/opt/php-5.6/sbin/php-fpm --nodaemonize --fpm-config /opt/php-5.6/etc/php-fpm.conf

or just 
$/opt/php-5.6/sbin/php-fpm

 

or

found that error

Code:

[18-May-2018 15:43:41] ERROR: Unable to globalize '/opt/php-5.6/etc/php-fpm.d/*.conf' (ret=2) from /opt/php-5.6/etc/php-fpm.conf at line 545.
[18-May-2018 15:43:41] ERROR: failed to load configuration file '/opt/php-5.6/etc/php-fpm.conf'
[18-May-2018 15:43:41] ERROR: FPM initialization failed

 

ok, we now need to know what is going on in
/opt/php-5.6/etc/php-fpm.conf at line 545

as the error tells us

 

ah stupid me, it already tells us ...
/opt/php-5.6/etc/php-fpm.d/*.conf


no .conf files

either place the [www] part out of the php-fpm.conf and move it as new file into www.conf in that directory or create a dummy fpm.conf / or even dummy page for it.


issue is: daemon doesn't start with empty directory and ISPConfig kind of expects the daemon to be running or else it will mix up the different versions.


A basic conf will do like

Code:

[root@host] /etc/php/7.1/fpm# cat pool.d/www.conf  | grep -v ";"
[www]
user = www-data
group = www-data
listen = /run/php/php7.1-fpm.sock
listen.owner = www-data
listen.group = www-data
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3

well yeah I was lazy, used precompiled package from php maintainer so I have 5.6 to 7.2 on my system, well organized folder structure, working as a treat except this dummy config

edit: don't forget to move sections, it won't start having two [www] pools cause of the name and probably same port, too. move it move it move it - I like to

 

So i think i solved simply removing the line 545, now it don't need any .conf file, the www section is already in the php-fpm.conf file
perhaps previously i installed php-fpm from apt.
if I executed a which and I see it is using the apt one and not compiled one...

Code:

which php-fpm5.6
/usr/sbin/php-fpm5.6

May I

Code:

apt-get remove php5.6*

or

Code:

apt-get remove --purge php5.6*

Can this influence the compiled one?
How I change default php5.6 using the compiled one instead the installed one? (I don't remember and I wont'd crash something)

 

Oops... I think that folder is needed for www's files so it's not real what I wrote... Did you confirm?

 

yeah, ispconfig will place additional conf files into the folder for each website. so the line is important, it includes the different files.
Check that the directory exists, the include line is working again and if it complaints, move the [www] section out of the php-fpm.conf to its own .conf in the pool directory.
This will get it working.

I don't know what you have on your system to be able to remove another php 5.6 installation, but this is something you should know what how where it is.

Setting phps default can be done using a lot of

Code:

update-alternatives --config

you might have to set up a lot of symlinks - don't forget phpize, php-cgi, php, php-fpm, ... look into bin/sbin dir

 

Inspecting PHP7.2 php-fpm.conf file result:

Code:

/opt/php-7.2/etc# cat php-fpm.conf | grep -v ";"
[global]
pid = run/php-fpm.pid
include=/opt/php-7.2/etc/php-fpm.d/*.conf

Inspecting PHP7.2 php-fpm.d file result:

Code:

/opt/php-7.2/etc/php-fpm.d# cat www.conf | grep -v ";"
[www]
user = www-data
group = www-data
listen = 127.0.0.1:8998
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3

Inspecting PHP5.6 php-fpm.conf file result:

Code:

/opt/php-5.6/etc# cat php-fpm.conf | grep -v ";"
[global]
pid = run/php-fpm.pid
[www]
user = www-data
group = www-data
listen = 127.0.0.1:8997
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3

This show differences between 2 versiones.
If I understood right the right way is to move the www section out of file and create folder php-fpm.d/www.conf

Thanks
