部署
部署6个虚拟机（192.168.1.11-16），其中3个master节点，3个slave节点。
在每一台虚拟机运行如下shell脚本：
1#!/usr/bin/env bash 2 3sudo apt-get update 4sudo apt-get install -y build-essential tcl ruby 5cd /tmp 6curl -O http://download.redis.io/redis-stable.tar.gz 7tar xzvf redis-stable.tar.gz 8cd redis-stable 9make 10make test 11sudo make install 12sudo mkdir /etc/redis 13sudo cp /tmp/redis-stable/redis.conf /etc/redis 14sudo sed -i 's/supervised no/supervised systemd/' /etc/redis/redis.conf 15sudo sed -i 's/protected-mode yes/protected-mode no/' /etc/redis/redis.conf 16sudo sed -i 's/bind 127.0.0.1/#bind 127.0.0.1/' /etc/redis/redis.conf 17sudo sed -i 's/# cluster-enabled yes/cluster-enabled yes/' /etc/redis/redis.conf 18sudo sed -i 's#logfile ""#logfile "/var/lib/redis/redis.log"#' /etc/redis/redis.conf 19sudo sed -i 's#dir ./#dir /var/lib/redis#' /etc/redis/redis.conf 20cat >redis.service <<EOF 21[Unit] 22Description=Redis In-Memory Data Store 23After=network.target 24 25[Service] 26User=redis 27Group=redis 28ExecStart=/usr/local/bin/redis-server /etc/redis/redis.conf 29ExecStop=/usr/local/bin/redis-cli shutdown 30Restart=always 31 32[Install] 33WantedBy=multi-user.target 34EOF 35 36sudo cp redis.service /etc/systemd/system/redis.service 37 38sudo adduser --system --group --no-create-home redis 39sudo mkdir /var/lib/redis 40sudo chown redis:redis /var/lib/redis 41sudo chmod 770 /var/lib/redis 42 43sudo systemctl start redis 44sudo systemctl status redis
或者直接执行: wget -O - https://gitee.com/power/repo/raw/master/redis-cluster.sh | sh
脚本会下载编译Redis，并安装为systemd服务，端口为6379，监听任意地址。日志文件是/var/lib/redis/redis.log
集群
在任一虚拟机执行命令：
sudo redis-cli --cluster create --cluster-replicas 1 192.168.1.11:6379 192.168.1.12:6379 192.168.1.13:6379 192.168.1.14:6379 192.168.1.15:6379 192.168.1.16:6379
将会创建
3个master节点：192.168.1.11:6379 192.168.1.12:6379 192.168.1.13:6379
3个slave节点：192.168.1.14:6379 192.168.1.15:6379 192.168.1.16:6379
测试
redis-cli --cluster check 127.0.0.1:6379
在节点1进入redis-cli -c，执行命令：
SET key test
在节点2进入redis-cli -c，执行命令：
GET key
客户端
Spring Boot配置：
spring.redis.cluster.nodes=192.168.1.11:6379, 192.168.1.12:6379, 192.168.1.13:6379
