centos7+redis6集群安装

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/
在这里插入图片描述
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      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 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
