Installation and configuration of Redis cluster under Mac

1. Install Redis, execute command Brew install Redis

2. After the installation is complete, brew info Redis can view the installation path of Redis

3.cd /usr/local/cellar/redis/3.0.7 entering the Redis installation path

4. Create a cluster/7001,7002,7003 directory under/USR/LOCAL/ETC

5. Copy the Redis-server redis.conf file from the bin directory in the 3 step to the 7001,7002,7003 directory,

Modify the port in redis.conf to 7000,7001,7002;

Modify the Cluster-config-file parameter of the redis.conf file to

Nodes-7000.conf

Nodes-7001.conf

Nodes-7002.conf

Turn on cluster-related parameters

Daemonize Yes

cluster-enabled Yes

Cluster-config-file nodes.conf

Cluster-node-timeout 5000

AppendOnly Yes

6. Start 3 instances respectively

CD /usr/local/etc /cluster/7000

Redis-server redis.conf

CD /usr/local/etc /cluster/7001

Redis-server redis.conf

CD /usr/local/etc /cluster/7002

Redis-server redis.conf

the configuration file path for the corresponding node: /usr/local/var/db/redis

7. View boot status via client login

Redis-cli-p 7000

Up to now 3 service-side has been successfully started, but the cluster is not built automatically because the three are still in the "I don't know you, you don't belong to me" state, each of which is a solitary redis node, or a cluster that contains only a single node To complete the cluster construction by cluster meet command

8. 127.0.0.1:7000> cluster meet 127.0.0.1 7001

Ok

127.0.0.1:7000> Cluster Meet 127.0.0.1 7002

Ok

127.0.0.1:7000> cluster Nodes

By cluster nodes to see if the cluster build is successful, does the cluster build work complete? No, we can see the status of the cluster through the cluster Info command.

9.127.0.0.1:7000> Cluster Info

Cluster_state:fail

Cluster_slots_assigned:6

Cluster_slots_ok:6

cluster_slots_pfail:0

cluster_slots_fail:0

Cluster_known_nodes:3

Cluster_size:3

Cluster_current_epoch:2

Cluster_my_epoch:1

Cluster_stats_messages_sent:35

Cluster_stats_messages_received:35

you can see that the cluster status is the fail state, why is the fail status? By querying the Redis fail status explanation, 16,384 Hash Slots have not yet been assigned to nodes in the cluster. We'll assign slots next .

10. There are two ways to allocate slots:

One is to allocate the slots in the slot through the cluster addslots command, which is more cumbersome by adding slots to the specified nodes.

The second is specified directly in the configuration file, which is the nodes-7000/7001/7002.conf configuration file specified in step fifth, adding slots at the end of each file containing the lines in myself

Restart the Redis server with 3 nodes after configuration is complete

11.127.0.0.1:7000> Cluster Info

Cluster_state:ok

cluster_slots_assigned:16384

cluster_slots_ok:16384

The Redis cluster configuration is complete so that the client can enter Set,get

127.0.0.1:7000> Set Hello World

Ok

127.0.0.1:7000> Get Hello

"World"

127.0.0.1:7000>
