Автоматическое включение заглушки для graylog (на препроде)

Настроено на препроде на с07-nginx01.

Скрипт выбирает все файлы *graylog*.conf из /etc/nginx/conf.d/ и создаёт для них соответствующие флаги .maintenance в /tmp/ramdisk.

Attention

Cкрипт не будет работать корректно, если в именах файлов встретятся пробелы или символы переноса строки!

Файлы:

#!/bin/bash

# This script will find any site conf files matching ${sites_pattern}
# in ${nginx_sites_location} and create corresponding flag files
# in ${flag_path} location
#
# Won't work correctly for filenames containing spaces, but to hell with it right now
