--------------------

1.  安装 Redis 参见：[CentOS 1908 配置 Redis 5.0.7 一（单节点）][CentOS 1908 _ Redis 5.0.7]  
     
2.  进入 Redis 文件夹：
    
        [root@192 ~]# cd redis-5.0.7/
        [root@192 redis-5.0.7]#
3.  创建集群文件夹并复制集群配置文件：
    
        mkdir cluster
        cd cluster
        cp ../redis.conf ./redis-6001.conf
        cp ../redis.conf ./redis-6002.conf
        cp ../redis.conf ./redis-6003.conf
        cp ../redis.conf ./redis-6004.conf
        cp ../redis.conf ./redis-6005.conf
        cp ../redis.conf ./redis-6006.conf
4.  修改配置文件：
    
    1.  修改 redis6001.conf 文件：
        
            # 注释掉（远程连接）
            # bind 127.0.0.1
            
            # 将 yes 改为 no（取消保护）
            protected-mode no
            
            # 将端口改为 6001
            port 6001
            
            # 开启后台运行
            daemonize yes
            
            # 修改 pid 文件名
            pidfile /var/run/redis_6001.pid
            
            # 取消注释
            cluster-enabled yes
            
            # 集群配置文件
            cluster-config-file nodes-6001.conf
    2.  其他文件修改内容参看上面。
5.  创建启动、停止 Redis 脚本：
    
    1.  启动脚本：
        
            vim start-all.sh
        
        内容如下：
        
            ../src/redis-server redis-6001.conf
            ../src/redis-server redis-6002.conf
            ../src/redis-server redis-6003.conf
            ../src/redis-server redis-6004.conf
            ../src/redis-server redis-6005.conf
            ../src/redis-server redis-6006.conf
    2.  停止脚本：
        
            vim stop-all.sh
        
        内容如下：
        
            ../src/redis-cli -p 6001 shutdown
            ../src/redis-cli -p 6002 shutdown
            ../src/redis-cli -p 6003 shutdown
            ../src/redis-cli -p 6004 shutdown
            ../src/redis-cli -p 6005 shutdown
            ../src/redis-cli -p 6006 shutdown
6.  给启动脚本授权：
    
        chmod +x start-all.sh
        chmod +x stop-all.sh
7.  启动：
    
        [root@192 cluster]# ./start-all.sh

        [root@192 cluster]#
8.  开通端口：
    
        firewall-cmd --zone=public --add-port=6001/tcp --permanent
        firewall-cmd --zone=public --add-port=6002/tcp --permanent
        firewall-cmd --zone=public --add-port=6003/tcp --permanent
        firewall-cmd --zone=public --add-port=6004/tcp --permanent
        firewall-cmd --zone=public --add-port=6005/tcp --permanent
        firewall-cmd --zone=public --add-port=6006/tcp --permanent
        
        firewall-cmd --reload
        
        firewall-cmd --list-all
9.  创建集群：  
    必须使用 IP（否则远程连接不上）：
    
        ../src/redis-cli --cluster create --cluster-replicas 1 192.168.8.133:6001 192.168.8.133:6002 192.168.8.133:6003 192.168.8.133:6004 192.168.8.133:6005 192.168.8.133:6006
    
    信息如下：  
    中间有提示，输入：yes

10. 查看集群状态：
    
        [root@192 cluster]# ../src/redis-cli --cluster info 192.168.8.133:6001
        192.168.8.133:6001 (027e7336...) -> 0 keys | 5461 slots | 1 slaves.
        192.168.8.133:6002 (37487e6b...) -> 0 keys | 5462 slots | 1 slaves.
        192.168.8.133:6003 (b4aead46...) -> 0 keys | 5461 slots | 1 slaves.
        [OK] 0 keys in 3 masters.
        0.00 keys per slot on average.
