# Service installer for redis server, runs interactively by default.
|
|
#
|
|
# To run this script non-interactively (for automation/provisioning purposes),
|
|
# feed the variables into the script. Any missing variables will be prompted!
|
|
# Tip: Environment variables also support command substitution (see REDIS_EXECUTABLE)
|
|
#
|
|
# Example:
|
|
#
|
|
# sudo REDIS_PORT=1234 \
|
|
# REDIS_CONFIG_FILE=/etc/redis/1234.conf \
|
|
# REDIS_LOG_FILE=/var/log/redis_1234.log \
|
|
# REDIS_DATA_DIR=/var/lib/redis/1234 \
|
|
# REDIS_EXECUTABLE=`command -v redis-server` ./utils/install_server.sh
|
|
#
|
|
# This generates a redis config file and an /etc/init.d script, and installs them.
|
|
#
|
|
# /!\ This script should be run as root
|
|
#
