Supported environments and packages

OS

DIRAC needs DIRACOS for its dependencies. DIRACOS includes all dependencies (except for glibc), including Python and Grid middleware.

DIRAC client installation is supported for all x86_64, aarch64, ppc64le Linux and Darwin installations using DIRACOS. This includes installations made by the pilots.

DIRAC server installation is supported for most x86_64 Linux installations using DIRACOS. Other architectures and platforms may work as a server installation, however this is on a best effort basis and is not regularly tested.

MySQL versions

MySQL is a hard dependency for all DIRAC servers installations. Supported versions:

  • MySQL 8.0
  • MariaDB versions "compatible" with the above MySQL versions.

MySQL server is not shipped with DIRAC. You are responsible of its administration.

While specific configurations may be applied for each MySQL Database connection, generic connection details can be applied in CS location below (the shown values are the defaults):

Systems
{
  Databases
  {
    User = Dirac
    Password = Dirac
    Host = localhost
    Port = 3306
  }
}

OpenSearch versions

OpenSearch is a non-optional dependency for DIRAC servers installations. OpenSearch server is not shipped with DIRAC. You are responsible of its administration.

You can run your OpenSearch cluster without authentication, or using User name and password, or using certificates. You may add the following parameters:

  • User (default:'')
  • Password (default:'')
  • Host (default:localhost)
  • Port (default:9201)
  • SSL (default:True)
  • CRT (default:True)
  • ca_certs (default:None)
  • client_key (default:None)
  • client_cert (default:None)
  • IndexPrefix (default:''). Prefix prepended to all DIRAC-created OpenSearch indexes. The prefix will be lower case only.

to the location:

Systems
{
  NoSQLDatabases
  {
    User = ...
    Password = ...
    ...
  }
}
