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 given 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 these 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-cli --cluster create, so that +an actual Redis cluster will be created. (If you're accessing your setup via a local container, ensure that the CLUSTER_HOST value is changed to your local IP) +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 "./create-cluster stop" to stop all the instances. After you stopped the instances you can use "./create-cluster start" to restart them if you change your mind. +2. Use "./create-cluster clean" to remove all the AOF / log files to restart with a clean environment. + +Use the command "./create-cluster help" to get the full list of features. diff --git a/utils/create-cluster/create-cluster b/utils/create-cluster/create-cluster new file mode 100755 index 0000000..d97ee2b --- /dev/null +++ b/utils/create-cluster/create-cluster @@ -0,0 +1,125 @@ +#!/bin/bash + +SCRIPT_DIR="$( cd -- "$( dirname -- "${BASH_SOURCE[0]}" )" &> /dev/null && pwd )" + +# Settings +BIN_PATH="$SCRIPT_DIR/../../src/" +CLUSTER_HOST=127.0.0.1 +PORT=30000 +TIMEOUT=2000 +NODES=6 +REPLICAS=1 +PROTECTED_MODE=yes +ADDITIONAL_OPTIONS="" + +# You may want to put the above config parameters into config.sh in order to +# override the defaults without modifying this script. + +if [ -a config.sh ] +then + source "config.sh" +fi + +# Computed vars +ENDPORT=$((PORT+NODES)) + +if [ "$1" == "start" ] +then + while [ $((PORT < ENDPORT)) != "0" ]; do + PORT=$((PORT+1)) + echo "Starting $PORT" + $BIN_PATH/redis-server --port $PORT --protected-mode $PROTECTED_MODE --cluster-enabled yes --cluster-config-file nodes-${PORT}.conf --cluster-node-timeout $TIMEOUT --appendonly yes --appendfilename appendonly-${PORT}.aof --appenddirname appendonlydir-${PORT} --dbfilename dump-${PORT}.rdb --logfile ${PORT}.log --daemonize yes ${ADDITIONAL_OPTIONS} + done + exit 0 +fi + +if [ "$1" == "create" ] +then + HOSTS="" + while [ $((PORT < ENDPORT)) != "0" ]; do + PORT=$((PORT+1)) + HOSTS="$HOSTS $CLUSTER_HOST:$PORT" + done + OPT_ARG="" + if [ "$2" == "-f" ]; then + OPT_ARG="--cluster-yes" + fi + $BIN_PATH/redis-cli --cluster create $HOSTS --cluster-replicas $REPLICAS $OPT_ARG + exit 0 +fi + +if [ "$1" == "stop" ] +then + while [ $((PORT < ENDPORT)) != "0" ]; do + PORT=$((PORT+1)) + echo "Stopping $PORT" + $BIN_PATH/redis-cli -p $PORT shutdown nosave + done + exit 0 +fi + +if [ "$1" == "watch" ] +then + PORT=$((PORT+1)) + while [ 1 ]; do + clear + date + $BIN_PATH/redis-cli -p $PORT cluster nodes | head -30 + sleep 1 + done + exit 0 +fi + +if [ "$1" == "tail" ] +then + INSTANCE=$2 + PORT=$((PORT+INSTANCE)) + tail -f ${PORT}.log + exit 0 +fi + +if [ "$1" == "tailall" ] +then + tail -f *.log + exit 0 +fi + +if [ "$1" == "call" ] +then + while [ $((PORT < ENDPORT)) != "0" ]; do + PORT=$((PORT+1)) + $BIN_PATH/redis-cli -p $PORT $2 $3 $4 $5 $6 $7 $8 $9 + done + exit 0 +fi + +if [ "$1" == "clean" ] +then + echo "Cleaning *.log" + rm -rf *.log + echo "Cleaning appendonlydir-*" + rm -rf appendonlydir-* + echo "Cleaning dump-*.rdb" + rm -rf dump-*.rdb + echo "Cleaning nodes-*.conf" + rm -rf nodes-*.conf + exit 0 +fi + +if [ "$1" == "clean-logs" ] +then + echo "Cleaning *.log" + rm -rf *.log + exit 0 +fi + +echo "Usage: $0 [start|create|stop|watch|tail|tailall|clean|clean-logs|call]" +echo "start -- Launch Redis Cluster instances." +echo "create [-f] -- Create a cluster using redis-cli --cluster create." +echo "stop -- Stop Redis Cluster instances." +echo "watch -- Show CLUSTER NODES output (first 30 lines) of first node." +echo "tail -- Run tail -f of instance at base port + ID." +echo "tailall -- Run tail -f for all the log files at once." +echo "clean -- Remove all instances data, logs, configs." +echo "clean-logs -- Remove just instances logs." +echo "call -- Call a command (up to 7 arguments) on all nodes." -- cgit v1.2.3
