Debian 9: mpm_worker, php-fpm ( roundcube, enigma, munin, phpmyadmin aliases fix )

If you use php trough fpm only ( the fcgi ispconfig not included ) and use sury / happened to have php 7.2 as default on debian 9
a2disconf php*-fpm except for php7.1-fpm since roundcube may fail with 7.2

also make sure you have one pool.d/www.conf for every php-fpm listening on sockets at different location so they startup and ISPConfig does not get issues with expected but not started daemons.

Hi there!

In order to enable http/2 on my server, I did the following, as suggested by Poliman:

Code:

a2enmod proxy
a2enmod proxy_fcgi
a2dismod php7.0
systemctl restart apache2
a2dismod mpm_prefork //again disable it
a2enmod mpm_event
systemctl restart apache2

When I do that, phpmyadmin and roundcube stops running as PHP code seems not interpreted anymore.
Do I have to change the apache conf files for these applications (e.g. in /etc/apache2/conf-available/roundcube.conf)? In which way?
If anyone could help me, it will be great! Because I really want to enable http/2 for performances but without breaking anything ;-)

Thanks!

 

Hi man. You have probably disabled each mpm_. Try two things:
1. Try a2enmod mpm_event.
2. Check apache logs /var/log/apache2 and paste what you have there.

Of course - if enabling again mpm_event won't help, you can enable again --> a2enmod php7.0 and a2enmod mpm_prefork.

 

Thanks for you answer but I already tried a2enmod mpm_event.
When I do that roundcube and phpmyadmin doesn't works because php is not interpreted. To fix that, I had to revert by a2enmod php7.0 and a2enmod mpm_prefork. roundcube and phpmyadmin works, but websites haven't the http/2 activated...

 

What appear in your logs when you try enable mpm_event and http/2?

 

Nothing special. http/2 works well on all websites. But if I go on roundcube or phpmyadmin, I don't see any kind of error in apache logs and I don't know log files which may contains these errors.

 

You can check /var/log/syslog or /var/log/apache2/error.log or /var/log/php***.log

 

I just checked and nothing is log into these files when I active mpm_event and I browse on phpmyadmin and/or webmail... The only thing I see, is the php source code in clear text.
So, I don't know where to search...

 

Hmm, hard to say. Which apache version do you have?

 

I'm under apache 2.4.25 on Debian 9.5.

 

Guys,
You can't imagine how fast mpm_event is.
My system is 4GB RAM. About 1.7GB RAM is usable and 300MB swap memory is occupied. When I enter roundcube webmail, it takes zero time. Don't waste your time on Ngnix any more.

 

Also try to install the evil Commie Google's pagespeed module. Make sure your are using the open-source version.

 

It's a matter of preference, not which one is the best.

 

I would love to use mpm_event for http/2 reason but still issues with roundcube / phpmyadmin when I enable it -> PHP is not interpreted... Do you have specific configuration files for each of them to enable mpm_event in roundcube / phpmyadmin?

 

zicguy,
Have you read my tips a few months ago?

You must STOP all apache 2.4 instances first before you try to switch to the new mpm_event.

 

Yes, but I'm not sure what I need to do. I already have proxy and proxy_fcgi enabled. Do I have to: apt purge libapache2-mod-php7.0 ?
What do you mean by "You must STOP all apache 2.4 instances first". Should I have to make: service apache2 stop before?
Can you give me a step by step process to make mpm_event works AND roundcube and phpmyadmin please?

 

I was wondering if it would be possible to summarize the procedure for enabling HTTP/2 on Debian/Ubuntu and keeping phpmyadmin at the same time.
Am I correct in the following:
First:

Code:

a2enmod proxy
a2enmod proxy_fcgi
a2dismod php7.0
systemctl restart apache2
a2dismod mpm_prefork //again disable it
a2enmod mpm_event
systemctl restart apache2

Second add this code WHERE? for phpmyadmin

Code:

Alias /phpmyadmin /usr/share/phpmyadmin
Directory /usr/share/phpmyadmin/setup>
    <IfModule mod_authz_core.c>
        <IfModule mod_authn_file.c>
            AuthType Basic
            AuthName "phpMyAdmin Setup"
            AuthUserFile /etc/phpmyadmin/htpasswd.setup
        </IfModule>
        Require valid-user
    </IfModule>
</Directory>

# Disallow web access to directories that don't need it
<Directory /usr/share/phpmyadmin/templates>
    Require all denied
</Directory>
<Directory /usr/share/phpmyadmin/libraries>
    Require all denied
</Directory>
<Directory /usr/share/phpmyadmin/setup/lib>
    Require all denied
</Directory>

and what (if any) other steps would be required?
Any per-site configurations?
Thanks,

 

Thanks. I have a new site going live this weekend and may plow ahead myself. I'll post here if I discover anything or encounter problems.

 

FYI, I solve my issues to make roundcube and phpmyadmin works with mpm_event enabled, and of course, http/2 enabled. I only missed to enable the php7.0-fpm mod... So, to enable http/2 without side effects on my server I had to do the following:

Code:

a2enconf php7.0-fpm
systemctl reload apache2
a2dismod php7.0
systemctl restart apache2
a2dismod mpm_prefork
a2enmod mpm_event
systemctl restart apache2

If it can helps someone...
