System preparations

When running ApiOmat in a non-testing environment, some settings should be done in the underlying operation system to ensure that all features are working as expected.

License Server reachability

To contact the license server and activate the license, YAMBAS must be able to contact the license server at https://apiomat.org/algas; it may be necesary to set up both IPs for this domain ( in proxy and firewall settings.

Package dependencies

The following packages are required when installing ApiOmat with one of our Linux packages:


  • debconf

  • curl

  • apache2

  • libapache2-mod-php5

  • php5-mcrypt

  • php5-curl

  • php-pear


  • curl

  • httpd (or apache2 for suse)

  • php5

  • php5-curl

  • php5-mcrypt

  • php5-pear

  • wget

  • policycoreutils-python

Red Hat

The following packages, installed on a Red Hat 7 installation solves the dependency issues:


ApiOmat sends eMails for forgotten password or other purposes. Therefore, a proper email configuration or a local SMTP server on localhost, listening on port 25, is needed. If using a local email server, hMailServer for windows or Postfix for linux are recommended.

Postfix settings:

  • Kind: "Satellite system"

  • SMTP-Relay-Server: IP of load balancer


The following settings are assumed:

  • All hosts know each other by name. The name resolution is preferably done via local settings and not via a public DNS server

  • The application server can reach the URL which is later used to access ApiOmat from outside

  • Neither the IP nor the hostname of any of the hosts is changing


When using more than one application server, a load balancer on top of the ApiOmat system is required. The load balancer can use the URL <BASEURL>/yambas/rest to check if the YAMBAS services are running. The following settings have to be done:

  • Install SSL certificate in Load Balancer

  • Algorithm: Persistence/Sticky (after the first request, all further ones for a specific user are routed to the same application server)

  • Use the URL of the load balancer as yambasHost setting in ApiOmat

Character encoding

In order to avoid possible problems with special characters in module-code or model-data be sure that the character encoding in the environment you are about to run your application server in is set to UTF-8. Check your system documentation and the documentation of your application server to find out more.
