portalmec-sidekiq.service

+#
+# This file tells systemd how to run Sidekiq as a 24/7 long-running daemon.
+#
+# Customize this file based on your bundler location, app directory, etc.
+# Customize and copy this into /usr/lib/systemd/system (CentOS) or /lib/systemd/system or /etc/systemd/system (Debian).
+# Then run:
+#   - systemctl enable sidekiq
+#   - systemctl {start,stop,restart} sidekiq
+#
+# This file corresponds to a single Sidekiq process.  Add multiple copies
+# to run multiple processes (sidekiq-1, sidekiq-2, etc).
+#
+# Use `journalctl -u sidekiq -rn 100` to view the last 100 lines of log output.
