Description Mike McCune 2019-05-17 21:24:43 UTC 
The following settings are required to tune a Satellite 6 server for scale and are only available in custom-heira.yaml. We need to add these as options as installer flags if possible:

apache::mod::passenger::passenger_max_pool_size: 30
apache::mod::passenger::passenger_max_request_queue_size: 1000
apache::mod::passenger::passenger_max_requests: 1000

apache::mod::prefork::serverlimit: 1024
apache::mod::prefork::maxclients: 1024
apache::mod::prefork::maxrequestsperchild: 4000

qpid::open_file_limit: 65536
qpid::router::open_file_limit: 150100

candlepin::java_opts: "-Xms1024m -Xmx8192m"


postgresql::server::config_entries:
  max_connections: 1000
  shared_buffers: 4GB
  work_mem: 4MB
  checkpoint_segments: 32
  checkpoint_completion_target: 0.9
  effective_cache_size: 16GB
  autovacuum_vacuum_cost_limit: 2000
  log_min_duration_statement: 500


some of these may rely on changes being needed in the upstream puppet modules for Apache and Postgres, but as we work to provide better options for customers to *properly* tune their Satellite with our installer, we need to move these common used parameters out of custom-heira.yaml into proper flags + answer file locations.

This issue has been successfully verified in 6.7 Snap10, now user can change the deployment size as per their requirement using satellite-installer.

# satellite-installer --help
 --tuning INSTALLATION_SIZE    Tune for an installation size. Choices: default, medium, large, extra-large, extra-extra-large (default: "default")

# satellite-installer --tuning medium --disable-system-checks 
Installing             Done                                               [100%] [................................................................................................................................]

  Success!

# grep tuning /etc/foreman-installer/scenarios.d/satellite.yaml
  tuning: medium
