Step-by-Step Guide to Setting Up a Redis Cluster on Multiple Servers

1. Redis environment

IP addresses and ports for the six Redis instances:

192.168.240.234 6380 6381

192.168.240.235 6382 6383

192.168.240.8 6384 6385

2. Create directories on each server

[root@hd01 ~]# mkdir -p /usr/local/redis/cluster/conf

[root@hd01 ~]# mkdir -p /usr/local/redis/cluster/data

[root@hd01 ~]# mkdir -p /usr/local/redis/cluster/log

3. Configuration files

On server hd01:

-rw-r--r-- 1 root root 904 Jun 21 10:36 redis-6380.conf

-rw-r--r-- 1 root root 904 Jun 21 10:38 redis-6381.conf

On server hd02:

-rw-r--r-- 1 root root 904 Jun 21 10:48 redis-6382.conf

-rw-r--r-- 1 root root 904 Jun 21 10:49 redis-6383.conf

On server hd03:

-rw-r--r-- 1 root root 902 Jun 19 15:32 redis-6384.conf

-rw-r--r-- 1 root root 902 Jun 19 15:32 redis-6385.conf

4. Start the six Redis nodes

[root@hd01 ~]# /usr/local/redis/bin/redis-server /usr/local/redis/cluster/conf/redis-6380.conf

[root@hd01 ~]# /usr/local/redis/bin/redis-server /usr/local/redis/cluster/conf/redis-6381.conf

[root@hd02 ~]# /usr/local/redis/bin/redis-server /usr/local/redis/cluster/conf/redis-6382.conf

[root@hd02 ~]# /usr/local/redis/bin/redis-server /usr/local/redis/cluster/conf/redis-6383.conf

[root@hd03 ~]# /usr/local/redis/bin/redis-server /usr/local/redis/cluster/conf/redis-6384.conf

[root@hd03 ~]# /usr/local/redis/bin/redis-server /usr/local/redis/cluster/conf/redis-6385.conf

5. Initialize the cluster

[root@hd02 ~]# /usr/local/redis/bin/redis-cli -a 123456 --cluster create 192.168.240.234:6380 192.168.240.234:6381 192.168.240.235:6382 192.168.240.235:6383 192.168.240.8:6384 192.168.240.8:6385 --cluster-replicas 1
