Problem with multiple PHP versions

I installed a new clean "Perfect server" based on Debian Jessie in a openvz vps on my own local home server. After that went well i installed multiple php versions Latest php 5.3, 5.4, 5.5 fpm and cgi.

Wen i test those 3 cgi versions they all three work right away in few seconds after i change te version te test page with phpinfo(); show the correct version. But wen i want to change the fpm versions this doesn't change the verion. I have to restart the vps to make the version change work.

Is this normal behavior or is something wrong?

 

please check your custom init-script and correct paths to make sure there are no mistakes or typos within.
I have two different additional php configurations working like a charm, so I assume there's an issue somewhere.

 

i checked the init script and they look good to me but in syslog i see this:
Feb 18 18:40:04 ispconfig systemd[1]: Unit php-5.5.32-fpm.service cannot be reloaded because it is inactive.

To me it looks like php 5.3, 5.4, 5.5 fpm are all running but syslog says they are not running.

 

you're using systemd and therefore I guess it's debian jessie but you followed wheezy tutorial => you're missing systemd configurations.
Check https://www.howtoforge.com/tutorial/how-to-install-php-7-on-debian/ [ 3 Create the init script and systemd unit file ]

 

Yes that is what I did.
Great, thank you for pointing me in the right direction.
I will let you know if that fixed things but I'm pretty sure that's it.

 

I changed things like in the php7 tutorial but no luck it doesn't want to work.
This is what is in the syslog maybe it tells you something what might going on.

well I won't say "without luck" looks good for the reloading php-fpm part ( no service can't be reloaded anymore ).

I don't know what's wrong with your apache but a quick google pointed me to many recent bug posts. Some say there's uncleaned memory thus reloading apache doesn't work but restart with a few seconds in between ( issue would happen after running logrotate for some ppl ).

What I also found was something more close to what you're doing - interesting thing it's the same solution as for someone else having bind9 not starting at system boot but working nicely when starting by hand:
https://www.upcloud.com/support/apache2-problems-on-cloud-server/
It recommends to reinstall apache2 package ( first remove and then install again )

 

Thank you again I searched google up and down with those errors I found in syslog but I didn't found what you found.
Not that you think i'm not searching because I do always befor I ask for help her.

I removed Apache2 en reinstalled the package and rebooted. Now ispconfig doesn't work anymore at all and the test site doesn't work anymore either.

Good thing I have a backup of the clean ispconfig vps without all the php versions so I will start all over again tomorrow and let you know here how it went. Fingers crossed.

 

weird - did you purge remove apache? and no didn't mean to say you're lazy, just mentioned it was not based on some knowledge I have.
Since it's a rather unusual issue I hope it won't happen again.

 

yeah I did add --purge wen I removed apache, maybe I shouldn't have done that. Anyway the vps is destroyed and the vps is restored from the backup and ready to try again tomorrow or the day after wen I have the time. Hopefully more luck then.

 

Tonight i installed additional php 7 to my debian 8 ispconfig 3 vps. Everything went well so i thought. After i configured everything as in the tutorial. I setup a test domain and a test website which works as it should with the default php. Then i switched to php 7.0.3 wen i reloaded the php script with phpinfo() function it showed a error 500 page.

befor i switched to php 7 i opened 3x putty i tailed syslog and watch "ps aux | grep php" and /var/log/ispconfig/httpd/testdomain.org/error.log but nothing happenned no error of anything i could see happening. Only thing what happened was with putty were i watched ps aux | grep php there web1 disapeared while it should have switched to the other php-fpm 7.0.3 but it didn't it just disapperead.

Then i switched back to the default php version that worked the page works again with the default php version.

Switching back and fort between default and php-cgi 7.0.3 works.

Kind of the same behavior as yesterday.

 

I did some testing for myself now and can confirm there are some issues when switching php-fpm versions.
Seems the issue is related to the order in which services gets reloaded/restartet. I guess there's a need for some patches to ISPConfig.

Unfortunally I don't have time to dig further right now but I'll try to check on that later.

 

Thank you for letting know and confirming its not working right.
Hopefully it can be solved. Its way above my knowledge I am afraid.

 

While in theory everything is issued in the right order when switching php versions,

Code:

However the reload/restart procedure sometimes fails leaving one or the other php version in "stopped" state. If that happens apache also does not reload the config.
After restarting php5,7 and apache several times I was able to switch between PHP versions without error.

Since I'm new to systemd and there are no useable log infos on why reload failes I still need some time to play with that. Just wanted to give you a small update.

 

Thank you for the update.

I tried what you wrote to restart php 5 & 7 and Apache several times. For me no luck. I restarted php 5 & 7 and Apache several times with service restart and also restarted via the init scripts but no luck it does not want to switch to php7. Even wen I restart the vps still no php7-fpm. Wen I switch back to the default php5-fpm that works right away.

The strange thing is that the static html default page does not work either wen i switch to php7. Normaly i would expect the phpinfo script would not work but a simple static html should work so i think there is more going on then php7 only the web1 doesn't run. Wen i watch ps aux | grep php i see web1 disappear wen i switch to php7-fpm and coming back wen i switch to default php5-fpm.

Great there is a solution. The only thing is i don´t understand it completly. One thing i don´t understand is the answer on your question what exactly to put in the init script path. I changed it too php-7.0.3-fpm.

Then I deleted the init scripts php-7.0.3-fpm and php5-fpm and remove the boot links with update-rc.d. After a reboot php5-fpm works but switching to php7-fpm still no joy.

Could you please explain what i exactly have to do to make it work?

Thanks btw for the update / link to the other thread about this.

 

Hi, i prefer to write here instead open a new thread. I followed this tutorial
Not working for me. I select the php version in the domain tab and click save. Then, open a phpinfo page that shows i'm using the default version of PHP instead the installed one.

 

Since I am on Debian 8 and systemd is the supported way to go I first made sure the initd-script is disabled

Code:

insserv -r php-7.0.3-fpm

Then made sure the systemd script is enabled

Code:

systemctl enable php-7.0.3-fpm.service

Within ISPConfig at Additional PHP-Version "Path to the PHP-FPM init script" expects the name of the systemd .service file, which in my case is php-7.0.3-fpm.service - but without .service extension. So the "Path to init script" is: php-7.0.3-fpm

Works like a charm, did some rebooting and switching - all fine, no 503.

Are you on Debian 7? What do you see when setting System > Server Config > Loglevel to "Debug" and run /usr/local/ispconfig/server/server.sh on terminal right after switching PHP version?
Are you using FPM or FastCGI method? Which Apache modules are installed and enabled? ( type a2dismod, press tab two times and you get a list, if not make use of . /etc/bash_completion if installed )

 

Thanks for quick answer. I'm using Debian 7.
When type server.sh:

When type a2dismod:

I'm using the FPM method.

Thanks in advance
