Configuration DB

Mariadb myslq init

Systemd

all you need to have your service to start is

  1. a configuration db key foo of type service with status enabled
  2. a dropin file as this one

/usr/lib/systemd/system/foo.service.d/50koozali.conf

[Service]
#first we reset the ExecStartPre
ExecStartPre=
#our needs
ExecStartPre=-/sbin/e-smith/service-status foo
ExecStartPre=-/sbin/e-smith/expand-template /opt/foo/foo.conf

Restart=always
[Install]
#so it start on boot
WantedBy=sme-server.target

PHP-FPM

all you need is to add and improve this fragment .

What version of php it will be used against depends on the value you set on the line "if ($PHP_VERSION eq '80'){". This template is called for every version of php using the magic of template.metadata.

smeserver-foo-1.0/root/etc/e-smith/templates/etc/php-fpm.d/www.conf/15foo

  if (($foo{'status'} || 'disabled') eq 'enabled'){

    my $memory_limit = ($foo{MemoryLimit} || '500M');
    $memory_limit .= 'M' if ($memory_limit =~ m/^\d+$/);
    my $open_basedir= $foo{PHPBaseDir} || '';
    $open_basedir = "/opt/foo/html/:/var/log/foo/:/var/lib/php/cacti:$open_basedir";
    my $id = 'cacti';
    my $max_children = $foo{'PHPmaxChildren'} || 20;

you will also need the specific files created and accessible by www, that is done in the spec file for the permission and you need also to create them

mkdir -p smeserver-foo-1.0/root/var/lib/php/foo/{session,tmp,opcache)
mkdir -p smeserver-foo-1.0/root/var/log/php/foo
mkdir -p smeserver-foo-1.0/root/var/log/foo
