Redis集羣的搭建

環境：CentOS七、Redis-5.0.4版本。

一、 Redis官網(http://redis.io/download)下載Redis。下載地址：http://download.redis.io/releases/redis-5.0.4.tar.gz

二、 將下載的Redis文件上傳到CentOS系統中。

三、 安裝gcc

yum install gcc-c++

四、 解壓文件

tar -zvxf redis-5.0.4.tar.gz

五、執行make命令

cd redis-5.0.4
make

六、修改redis-5.0.4/utils/create-cluster目錄下create-cluster腳本,其中PORT=30000，NODES=6表示集羣有6個節點，端口從30001開始至30006，能夠根據自身需求自行調整，如需遠程訪問，請在--daemonize yes 後加入protected-mode no，並將127.0.0.1換爲本機地址

#!/bin/bash

# Settings
PORT=30000
TIMEOUT=2000
NODES=6
REPLICAS=1

# 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"
        ../../src/redis-server --port $PORT --cluster-enabled yes --cluster-config-file nodes-${PORT}.conf --cluster-node-timeout $TIMEOUT --appendonly yes --appendfilename appendonly-${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-cli --cluster create $HOSTS --cluster-replicas $REPLICAS
    exit 0
fi

if [ "$1" == "stop" ]
then
    while [ $((PORT < ENDPORT)) != "0" ]; do
        PORT=$((PORT+1))
        echo "Stopping $PORT"
        ../../src/redis-cli -p $PORT shutdown nosave
    done
    exit 0
fi

if [ "$1" == "watch" ]
then
    PORT=$((PORT+1))
    while [ 1 ]; do
        clear
        date
        ../../src/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" == "call" ]
then
    while [ $((PORT < ENDPORT)) != "0" ]; do
        PORT=$((PORT+1))
        ../../src/redis-cli -p $PORT $2 $3 $4 $5 $6 $7 $8 $9
    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

if [ "$1" == "clean-logs" ]
then
    rm -rf *.log
    exit 0
fi

echo "Usage: $0 [start|create|stop|watch|tail|clean]"
echo "start       -- Launch Redis Cluster instances."
echo "create      -- 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 <id>   -- Run tail -f of instance at base port + ID."
echo "clean       -- Remove all instances data, logs, configs."
echo "clean-logs  -- Remove just instances logs."

七、建立集羣,運行如下命令，在選則框中選擇yes：

./create-cluster start
./create-cluster create

八、中止集羣：

./create-cluster stop

九、參數說明

port  7000                                        //端口7000,7002,7003        
bind 本機ip                                       //默認ip爲127.0.0.1 須要改成其餘節點機器可訪問的ip 不然建立集羣時沒法訪問對應的端口，沒法建立集羣
daemonize    yes                               //redis後臺運行
pidfile  /var/run/redis_7000.pid          //pidfile文件對應7000,7001,7002
cluster-enabled  yes                           //開啓集羣  把註釋#去掉
cluster-config-file  nodes_7000.conf   //集羣的配置  配置文件首次啓動自動生成 7000,7001,7002
cluster-node-timeout  15000                //請求超時  默認15秒，可自行設置
appendonly  yes                           //aof日誌開啓  有須要就開啓，它會每次寫操做都記錄一條日誌
