Its main goal is to allow manual +testing in a condition which is not easy to replicate with the Redis cluster +unit tests, for example when a lot of instances are needed in order to trigger +a give bug. + +The tool can also be used just to easily create a number of instances in a +Redis Cluster in order to experiment a bit with the system. + +USAGE +--- + +To create a cluster, follow this steps: + +1. Edit create-cluster and change the start / end port, depending on the +number of instances you want to create. +2. Use "./create-cluster start" in order to run the instances. +3. Use "./create-cluster create" in order to execute redis-trib create, so that +an actual Redis cluster will be created. +4. Now you are ready to play with the cluster. AOF files and logs for each instances are created in the current directory. + +In order to stop a cluster: + +1. Use "./craete-cluster stop" to stop all the instances. After you stopped the instances you can use "./create-cluster start" to restart them if you change ideas. +2. Use "./create-cluster clean" to remove all the AOF / log files to restat with a clean environment. + +It is currently hardcoded that you start a cluster where each master has one slave, since the script is pretty basic. diff --git a/utils/create-cluster/create-cluster b/utils/create-cluster/create-cluster new file mode 100755 index 000000000..80161587e --- /dev/null +++ b/utils/create-cluster/create-cluster @@ -0,0 +1,66 @@ +#!/bin/bash + +PORT=30000 +ENDPORT=30006 + +if [ "$1" == "start" ] +then + while [ $((PORT < ENDPORT)) != "0" ]; do + PORT=$((PORT+1)) + echo "Starting $PORT" + ../../src/redis-server --port $PORT --cluster-enabled yes --cluster-config-file nodes-${PORT}.conf --cluster-node-timeout 5 --appendonly yes --appendfilename appendonly-${PORT}.aof --dbfilename dump-${PORT}.rdb --logfile ${PORT}.log --daemonize yes + done + exit 0 +fi + +if [ "$1" == "create" ] +then + HOSTS="" + while [ $((PORT < ENDPORT)) != "0" ]; do + PORT=$((PORT+1)) + HOSTS="$HOSTS 127.0.0.1:$PORT" + done + ../../src/redis-trib.rb create --replicas 1 $HOSTS + exit 0 +fi + +if [ "$1" == "stop" ] +then + while [ $((PORT < ENDPORT)) != "0" ]; do + PORT=$((PORT+1)) + echo "Stopping $PORT" + redis-cli -p $PORT shutdown nosave + done + exit 0 +fi + +if [ "$1" == "join" ] +then + while [ $((PORT < ENDPORT)) != "0" ]; do + PORT=$((PORT+1)) + echo "Joining $PORT" + redis-cli -p $PORT CLUSTER MEET 127.0.0.1 10002 + done + + echo "Waiting 5 seconds" + sleep 5 + + PORT=30000 + while [ $((PORT < ENDPORT)) != "0" ]; do + PORT=$((PORT+1)) + echo "Replicate $PORT" + redis-cli -p $PORT CLUSTER REPLICATE $2 + done + exit 0 +fi + +if [ "$1" == "clean" ] +then + rm -rf *.log + rm -rf appendonly*.aof + rm -rf dump*.rdb + rm -rf nodes*.conf + exit 0 +fi + +echo "Usage: $0 [start|create|stop|join|clean]" |
