本文已参与「新人创作礼」活动，一起开启掘金创作之路。
环境准备
Redis：6.2.6 SpringBoot：v2.2.6.RELEASE Java：8 Maven：3.6.3
安装Redis
macOS安装：brew install redis
搭建集群
安装完Redis直接用我编写的脚本，一键启停。
集群启动脚本
脚本说明：自动创建9个Redis节点配置文件。 新建脚本文件run.sh，将下面脚本写入文件。
echo "==============================当前工作目录==============================="
workdir="$(cd $(dirname $0); pwd)/redis-cluster"
echo "$workdir"
# 层级文件创建
mkdir -p "$workdir"
cd "$workdir"
echo "=============================创建节点配置文件=============================="
for i in {1..9}; do
conf_file="$workdir/700${i}.conf"
conf_content="port 700${i}\r\ndaemonize no\r\ncluster-enabled yes\r\ncluster-config-file cluster-nodes-700${i}.conf\r\ncluster-node-timeout 1000\r\ncluster-replica-validity-factor 5\r\ncluster-migration-barrier 1\r\ncluster-require-full-coverage yes\r\ncluster-replica-no-failover no\r\nappendonly yes"
echo "创建文件并写入配置数据：$conf_file"
# 创建配置文件
touch "${conf_file}"
# 避免因为权限而找不到文件
chmod u+x "${conf_file}"
# 向配置文件写入数据
echo "${conf_content}" > "${conf_file}"
done
echo "==============================节点启动信息==============================="
conf_list=""
for i in {1..9}; do
redis-server "$workdir"/700"${i}".conf &
conf_list="$conf_list""[redis-cluster/700${i}.conf]"
done
echo "redis-server run with cluster node:{$conf_list}"
sleep 3s
echo "==============================集群节点信息==============================="
redis-cli -c -h 127.0.0.1 -p 7001 cluster nodes
echo "===============================集群信息=================================="
redis-cli -c -h 127.0.0.1 -p 7001 cluster info
echo "==============================集群槽位信息================================="
redis-cli --cluster create 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 127.0.0.1:7006 127.0.0.1:7007 127.0.0.1:7008 127.0.0.1:7009 --cluster-replicas 1
redis-cli -c -h 127.0.0.1 -p 7001 cluster slots
echo "==============================集群进程信息================================="
ps aux|grep redis
echo "===============================集群启动完成==============================="
echo "have fun!!!"
集群停止脚本
新建脚本文件stop.sh，将下面脚背写入文件。
echo "==============================当前工作目录==============================="
workdir=$(cd $(dirname $0); pwd)
echo "$workdir"
echo "==============================关闭集群节点==============================="
for i in {1..9}; do
redis-cli -p 700"$i" shutdown
echo "关闭节点{700$i} OK!"
done
echo "===============================集群关闭完成==============================="
echo "see you later..."

编写单元测试

@RunWith(SpringRunner.class)
@SpringBootTest(classes = {RedisAutoConfiguration.class})
public class AppTest {
@Autowired
private RedisTemplate<String, Map<String, String>> redisTemplate;
@Autowired
private StringRedisTemplate stringRedisTemplate;
@Test
public void redisTemplate() {
ValueOperations<String, Map<String, String>> ops = redisTemplate.opsForValue();
Map<String, String> map = new HashMap<>();
map.put("name", "《ik》");
map.put("author", "cxk");
ops.set("cxk", map);
System.out.println(ops.get("cxk"));
}
}
运行测试
1 启动Redis集群
可以通过bash启动。
也可以通过idea图形化启动。
启动效果：
关闭节点：见上述关闭脚本。
2 执行单元测试
测试结果：
