本文主要是介绍centos7+redis6集群安装，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
注意
需要yum install gcc
redis安装
1）redis下载：https://redis.io/
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
- cp /opt/redis-6.2.5/redis.conf /data/redis
- 修改redis.conf文件
daemonize yes
# bind 127.0.0.1 -::1
protected-mode no
- 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

[OK] All nodes agree about slots configuration.
>>> Check for open slots...
>>> Check slots coverage...
[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 k3 v3
OK
192.168.11.131:6380> set k4 v4

OK
192.168.11.131:6381>
其他
默认安装在/usr/local/bin下
