# 工程简介


#### 环境搭建

1. 下载redis安装包，进入目录，执行命令make install PREFIX=/Users/yuan/server/redis/cluster, 此时会在cluster生成bin目录
2. 在/Users/yuan/server/redis/cluster目录创建7001-7006目录
3. 把bin目录复制到7001-7006目录下
4. 修改redis.conf,改动如下：

```
port 7001
cluster-enabled yes
cluster-config-file /Users/yuan/server/redis/cluster/7001/nodes.conf

```
复制redis.conf到7001-7006目录下,主要要改动一下端口号

5. 编写启动文件start.sh

```
#!/bin/bash

cd /Users/yuan/server/redis/cluster/7001
./bin/redis-server /Users/yuan/server/redis/cluster/7001/redis.conf &


cd /Users/yuan/server/redis/cluster/7002
./bin/redis-server /Users/yuan/server/redis/cluster/7002/redis.conf &

cd /Users/yuan/server/redis/cluster/7003
./bin/redis-server /Users/yuan/server/redis/cluster/7003/redis.conf &


cd /Users/yuan/server/redis/cluster/7004
./bin/redis-server /Users/yuan/server/redis/cluster/7004/redis.conf &

cd /Users/yuan/server/redis/cluster/7005
./bin/redis-server /Users/yuan/server/redis/cluster/7005/redis.conf &

cd /Users/yuan/server/redis/cluster/7006
./bin/redis-server /Users/yuan/server/redis/cluster/7006/redis.conf &
```

6. 启动redis集群

```
./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 --cluster-replicas 1
```

7.扩容

```
a.启动7007
cd /Users/yuan/server/redis/cluster/7007
./bin/redis-server /Users/yuan/server/redis/cluster/7007/redis.conf &
b.添加到集群中
./bin/redis-cli --cluster add-node 127.0.0.1:7007 127.0.0.1:7001
c.分配槽
./bin/redis-cli --cluster reshard 127.0.0.1:7007
```





8.添加7007从节点7008

```
a.启动7008
b.添加从节点
./bin/redis-cli --cluster add-node 127.0.0.1:7008 127.0.0.1:7007 --cluster-slave --cluster-master-id b25b7fea333d7969406bb0f429d510e4d7487be7
```
