I. installation

1.1 create a directory

Mkdir-p / redis/cluster mkdir 7000 7001 7002 7003 7004 7005

1.5 copy and modify configuration fil

Cp / redis/redis-3.2.9/redis.conf / redis/cluster/7000 cp / redis/redis-3.2.9/redis.conf / redis/cluster/7001 cp / redis/redis-3.2.9/redis.conf / redis/cluster/7002 cp / redis/redis-3.2.9/redis.conf / redis/cluster/7003 cp / redis/redis-3.2.9/ Redis.conf / redis/cluster/7004 cp / redis/redis-3.2.9/redis.conf / redis/cluster/7005

1.6 modify the configuration file

# Port number port 7000 # launch daemonize yes in the background # Open Cluster cluster-enabled yes # Cluster Node profile cluster-config-file nodes-7000.conf # Cluster connection timeout cluster-node-timeout 5000 # process Pid file location pidfile / var/run/redis-7000.pid # enable aof appendonly yes # aof file path appendfilename "appendonly-7005.aof" # rdb file path dbfilename dump-7000.rdb

1.7 create a startup script

/ redis/redis-3.2.9/bin/redis-server / redis/cluster/7000/redis.conf / redis/redis-3.2.9/bin/redis-server / redis/cluster/7001/redis.conf / redis/redis-3.2.9/bin/redis-server / redis/cluster/7002/redis.conf / redis/redis-3.2.9/bin/redis-server / redis/cluster/7003/redis.conf / redis/redis-3.2.9/bin/redis-server / redis/cluster/7004/redis.conf / redis/redis-3.2.9/bin/redis-server / redis/cluster/7005/redis.conf

II. Cluster

2.1 Resource Pack

[root@redis2 ~] # yum install ruby rubygems- y [root@redis2 ~] # tar zxvf rubygems-2.4.6.tgz [root@redis2 ~] # chown-R root:root rubygems-2.4.6 [root@redis2 ~] # cd rubygems-2.4.6 ruby setup.rb gem sources-remove https://rubygems.org/ gem install redis-3.3.3.gem

2.2 create a cluster

Redis-trib create-- replicas 1 127.0.0.1VL 7000 127.0.0.1V 7001 127.0.1V 7002 127.0.0.1V 7003 127.0.1V 7003 127.0.1V 7004 127.0.1V 7005

The meaning of the command is as follows:

The command of the redis-trib.rb program is create, Cluster.

The option-replicas 1 means that we want to create a slave node for each master node in the cluster.

The other parameters that follow are the address lists of the instances, and we want the program to use the instances indicated by these addresses to create a new cluster.

To put it simply, the above command means that the redis-trib program will help us create a cluster of three master nodes and three slave nodes.

Then, redis-trib will print out a copy of the expected configuration to show you. If you think it is all right, you can type yes, and redis-trib will apply this configuration to the cluster:

> Creating cluster > Performing hash slots allocation on 6 nodes...

(type 'yes' to accept):

2.3 Cluster usage
