RSMQ
RSMQ is a lightweight message queue based on Redis.
Setup Redis Server on Docker
Start Redis server on docker:
docker run --name myredis -d redis
-------
A
Connect to the server with:
docker run -it --link myredis:redis --rm redis bash -c 'redis-cli -h redis'
------- ----- -----
A B B
or the full version:
docker run -it --link myredis:redis --rm redis bash -c 'exec redis-cli -h "$REDIS_PORT_6379_TCP_ADDR" -p "$REDIS_PORT_6379_TCP_PORT"'.
Now in redis console, use info to get the server's version;
keys * to list all keys;
set mykey "hello" to add a key/value pair.
get mykey to fetch the key's value.
Note:
- Names labled with "A" is the container's name of Redis server. Names labled with "B" is the name alias of Redis server container used by Redis client container.

apt-get update
apt-get install -y redis-server
Install rsmq: in project root folder, runnpm install rsmq;
Install rsmq-cli: npm install -g rsmq-cli;
rsmq config ls
rsmq create -q payment // create a new queue named "payment"
rsmq ls // list all queues
rsmq stats -q payment // print stats of queue "payment"
rsmq send "pay $1000" -q payment // send a message to "payment"
rsmq receive -q payment // receive a message from "payment"
