Redis集群模式是通过分片来实现数据的分布式存储和高可用性。下面是搭建Redis集群的步骤:
1. 下载Redis并解压缩:
```
$ wget http://download.redis.io/releases/redis-5.0.9.tar.gz
$ tar xzf redis-5.0.9.tar.gz
$ cd redis-5.0.9
```
2. 编译Redis:
```
$ make
```
3. 复制Redis二进制文件:
```
$ cp src/redis-cli src/redis-server /usr/local/bin/
```
4. 创建Redis集群的配置文件:
```
$ mkdir /redis_cluster
$ cd /redis_cluster
$ touch redis-7000.conf redis-7001.conf redis-7002.conf redis-7003.conf redis-7004.conf redis-7005.conf
```
5. 编辑配置文件:
```
# redis-7000.conf
port 7000
cluster-enabled yes
cluster-config-file nodes-7000.conf
cluster-node-timeout 5000
appendonly yes
# redis-7001.conf
port 7001
cluster-enabled yes
cluster-config-file nodes-7001.conf
cluster-node-timeout 5000
appendonly yes
# redis-7002.conf
port 7002
cluster-enabled yes
cluster-config-file nodes-7002.conf
cluster-node-timeout 5000
appendonly yes
# redis-7003.conf
port 7003
cluster-enabled yes
cluster-config-file nodes-7003.conf
cluster-node-timeout 5000
appendonly yes
# redis-7004.conf
port 7004
cluster-enabled yes
cluster-config-file nodes-7004.conf
cluster-node-timeout 5000
appendonly yes
# redis-7005.conf
port 7005
cluster-enabled yes
cluster-config-file nodes-7005.conf
cluster-node-timeout 5000
appendonly yes
```
6. 启动Redis集群:
```
$ redis-server redis-7000.conf
$ redis-server redis-7001.conf
$ redis-server redis-7002.conf
$ redis-server redis-7003.conf
$ redis-server redis-7004.conf
$ redis-server redis-7005.conf
```
7. 创建Redis集群:
```
$ redis-cli --cluster create 127.0.0.1:7000 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 --cluster-replicas 1
```
该命令创建了一个包含6个节点和1个副本的Redis集群。
8. 测试Redis集群:
```
$ redis-cli -c -p 7000
127.0.0.1:7000> set foo bar
OK
127.0.0.1:7000> get foo
"bar"
```
上述步骤完成后,就可以使用Redis集群模式进行数据的分布式存储和高可用性了。
