Ghost – добавяне в init скрипт

За да може Ghost да стартира автоматично при стартиране на операционната система, е необходимо да се добави в Init скриптовете.

За да го добавите, е необходимо да влезете в сървъра чрез SSH.

След това добавяте следния скрипт:

Забележка: Съдържанието на скрипта може да свалите и от тук Ghost init script

#!/bin/bash
#
# Service script for a Node.js application running under Forever.
#
# This is suitable for Fedora, Red Hat, CentOS and similar distributions.
# It will not work on Ubuntu or other Debian-style distributions!
#
# There is some perhaps unnecessary complexity going on in the relationship between
# Forever and the server process. See: https://github.com/indexzero/forever
#
# 1) Forever starts its own watchdog process, and keeps its own configuration data
# in /var/run/forever.
#
# 2) If the process dies, Forever will restart it: if it fails but continues to run,
# it won't be restarted.
#
# 3) If the process is stopped via this script, the pidfile is left in place; this
# helps when issues happen with failed stop attempts.
#
# 4) Which means the check for running/not running is complex, and involves parsing
# of the Forever list output.

И го добавяме, за да стартира автоматично:

Готово. При стартиране на операционната система, Ghost ще се стартира автоматично.
