    I saw this tuto how to include http2 inside ispconfig.

    Coul you confirm me if it's correct. I don't want to make a an mistake.

    nano /usr/local/ispconfig/server/conf/nginx_vhost.conf.master

    Replace :

    listen <tmpl_var name=’ip_address’>:443 ssl;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    <tmpl_if name=’ipv6_enabled’>
    listen [<tmpl_var name=’ipv6_address’>]:443 ssl;
    ssl_certificate <tmpl_var name=’document_root’>/ssl/<tmpl_var name=’ssl_domain’>.crt;
    ssl_certificate_key <tmpl_var name=’document_root’>/ssl/<tmpl_var name=’ssl_domain’>.key;

    by :

    <tmpl_if name=’ssl_enabled’>
    listen <tmpl_var name=’ip_address’>:443 ssl http2;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    <tmpl_if name=’ipv6_enabled’>
    listen [<tmpl_var name=’ipv6_address’>]:443 ssl http2;
    ssl_certificate /etc/letsencrypt/live/<tmpl_var name=’domain’>/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/<tmpl_var name=’domain’>/privkey.pem;

    copy the file /usr/local/ispconfig/server/conf/nginx_vhost.conf.master to /usr/local/ispconfig/server/conf-custom/nginx_vhost.conf.master

    and then edit the /usr/local/ispconfig/server/conf-custom/nginx_vhost.conf.master file in that way.

    The above config is for nginx web servers, not apache.

    Enable mod_http2, I think that's it, but I never tried.

    This http2 feature will be properly added in 3.2. In 3.1, I still manually edit the vhost to use it since I am using nginx. For apache, as stated above, you might need to enable its module first but I am not sure since I am not using apache anymore.

    Ok, I find a solution but what is the best

    to test
    <code>sudo a2enmod http2</code>
    and restart apache2

    Number 1 : Install all the website
    under ServerAdmin add
    <code>Protocols h2 http/1.1</code>
    restart apache2
    make the same thing for all website

    Number 2 : Install all the website
    <code>vi 000-default.conf</code>
    below DocumentRoot
    add <code>Protocols h2 http/1.1<code>
    For futur website I think ?

    I have to add the apache directive to the site options directly to enable http2.

    Sites -> Your domain -> Options

    Under "Apache Directives", put

    Protocols h2 h2c http/1.1

    Save it and it works.
    ahrasis, biforme and till like this.

    Adding this to apache2.conf does not work

    Protocols h2 h2c http/1.1
    ProtocolsHonorOrder On
    does it have something to do with
    Debian 9: 9.5 released

    need to disable

    but only enable with
    mpm_worker and mpm_event

    what is the proper way to do this in ispconfig?

    on debian 9 you do
    a2dismod mpm_prefork
    a2enmod mpm_worker
    a2enmod http2
    I'm not sure if they have fixed the mpm_event in debian 9.5 but I wouldn't bet / risk that.
    And mabye you add this to /etc/apache2/mods-available/http2.conf ( since there is none ) or into conf-available - dir and enable said files.

    mpm_event is the way to go!
  19. ISPConfig Developer ISPConfig Developer

    it is, for some... but it has a nasty bug since 2012 or 2014 at least which can drive you nuts!
    the last time I tested with at least debian 9.4 it was still in there, but not in 10, I doubt this has changed.

    keep in mind event and worker are not much different. event does have some tradeoffs worker doesn't have. it depends on your environment which to choose, and if u use keepalive.

    By now I already forgot almost all about apache2. But with regards to mpm_worker vs mpm_event, this link has some good explanation.
