### redis安装 ###

1）redis下载：https://redis.io/  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NuZGF5WVU_size_16_color_FFFFFF_t_70]  
2）rz命令上传到centos7的/opt目录下  
3）gcc --version、yum install gcc  
4）tar zxf redis-6.2.5.tar.gz、cd /opt/redis-6.2.5/、make、make install

### redis单机部署 ###

1.  cp /opt/redis-6.2.5/redis.conf /data/redis
2.  修改redis.conf文件

daemonize yes
    # bind 127.0.0.1 -::1
    protected-mode no

1.  启动并验证

[root@mac1 redis]# redis-server /data/redis/redis.conf
    [root@mac1 redis]# redis-cli -p 6379
    127.0.0.1:6379> ping
    PONG
    127.0.0.1:6379> set k1 v1
    OK
    127.0.0.1:6379> get k1
    "v1"
    127.0.0.1:6379> shutdown

### 集群 ###

1）配置  
/data/redis目录新建redis-6380.conf, 内容如下：

include /data/redis/redis.conf
    pidfile "/var/run/redis_6380.pid"
    port 6380
    dbfilename "dump_6380.rdb"
    
    cluster-enabled yes
    cluster-config-file nodes-6380.conf
    cluster-node-timeout 15000

同理，新建redis-6381.conf、redis-6382.conf、redis-6383.conf、redis-6384.conf、redis-6385.conf，内容分布是 将上面4个6380改为对应的端口6381、6382、6383、6384、6385

2）启动6个redis

[root@mac1 redis]# redis-server /data/redis/redis-6380.conf
    [root@mac1 redis]# redis-server /data/redis/redis-6381.conf
    [root@mac1 redis]# redis-server /data/redis/redis-6382.conf
    [root@mac1 redis]# redis-server /data/redis/redis-6383.conf
    [root@mac1 redis]# redis-server /data/redis/redis-6384.conf
    [root@mac1 redis]# redis-server /data/redis/redis-6385.conf
    [root@mac1 redis]# ps -ef | grep redis
    root      15740      1  0 22:58 ?        00:00:00 redis-server *:6380 [cluster]
    root      15746      1  0 22:58 ?        00:00:00 redis-server *:6381 [cluster]
    root      15752      1  0 22:58 ?        00:00:00 redis-server *:6382 [cluster]
    root      15758      1  0 22:58 ?        00:00:00 redis-server *:6383 [cluster]
    root      15764      1  0 22:58 ?        00:00:00 redis-server *:6384 [cluster]
    root      15770      1  0 22:58 ?        00:00:00 redis-server *:6385 [cluster]
    root      15778  10490  0 22:59 pts/0    00:00:00 grep --color=auto redis

3）创建集群：redis-cli --cluster create --cluster-replicas 1 192.168.11.131:6380 192.168.11.131:6381 192.168.11.131:6382 192.168.11.131:6383 192.168.11.131:6384 192.168.11.131:6385，中间需要输入yes，详细过程如下所示：

[root@mac1 src]# redis-cli --cluster create --cluster-replicas 1 192.168.11.131:6380 192.168.11.131:6381 192.168.11.131:6382 192.168.11.131:6383 192.168.11.131:6384 192.168.11.131:6385
    >>> Performing hash slots allocation on 6 nodes...

    [OK] All 16384 slots covered.

即主为80、81、82三台，从为83、84、85三台，slot一共有16384

4）验证

[root@mac1 src]# redis-cli -c -p 6380
    127.0.0.1:6380> set k1 v1
    -> Redirected to slot [12706] located at 192.168.11.131:6382
    OK
    192.168.11.131:6382> set k2 v2
    -> Redirected to slot [449] located at 192.168.11.131:6380

    OK
    192.168.11.131:6380> set k4 v4
    -> Redirected to slot [8455] located at 192.168.11.131:6381
