requirements

• java (8 or 11)
• redis (with activated keyspace notification)

installation

All of the mp state is kept in a redis database.

redis config

Since version 0.3.0 cmp relies on Keyspace Notifications. Therefore it is necassary to replace in /etc/redis/redis.conf:

notify-keyspace-events ""

by

notify-keyspace-events AK

and restart the service:

# restart
$ sudo systemctl restart redis.service

# check status
$ sudo systemctl status redis.service

cmp standalone version

Download the latest version from here. Set the environment variables (see next section). Start cmp with:

java -jar cmp-x.y.z-standalone.jar

environment variables
