# Sample verbose configuration file for Unicorn (not Rack)
|
|
#
|
|
# This configuration file documents many features of Unicorn
|
|
# that may not be needed for some applications. See
|
|
# https://yhbt.net/unicorn/examples/unicorn.conf.minimal.rb
|
|
# for a much simpler configuration file.
|
|
#
|
|
# See https://yhbt.net/unicorn/Unicorn/Configurator.html for complete
|
|
# documentation.
|
|
|
|
# Use at least one worker per core if you're on a dedicated server,
|
|
# more will usually help for _short_ waits on databases/caches.
|
|
worker_processes 4
|
|
|
|
# Since Unicorn is never exposed to outside clients, it does not need to
|
|
# run on the standard HTTP port (80), there is no reason to start Unicorn
|
|
# as root unless it's from system init scripts.
|
|
# If running the master process as root and the workers as an unprivileged
|
|
# user, do this to switch euid/egid in the workers (also chowns logs):
|
|
# user "unprivileged_user", "unprivileged_group"
|
|
|
|
# Help ensure your application will always spawn in the symlinked
|
|
# "current" directory that Capistrano sets up.
|
|

# # This allows a new master process to incrementally
