Redis Cluster Deployment documentation (UBUNTU15.10 System)
(To make the cluster work at least 3 primary nodes, here we will create 6 Redis nodes, of which three are the primary node, three are slave nodes, the corresponding Redis node IP and port correspondence is as follows)
127.0.0.1:7000
127.0.0.1:7001
127.0.0.1:7002
127.0.0.1:7003
127.0.0.1:7004
127.0.0.1:7005


1: Download Redis. Download 3.0.0 version, previous 2. Several versions do not support cluster mode
: http://download.redis.io/releases/redis-3.0.7.tar.gz
2: Upload server, unzip, compile

tar -zxvf redis-3.0. 7. Tar . GZ MV redis-3.0. 7 /usr/local/redis3. 0  /usr/local/redis3. 0  Make

After that, the Redis-server redis-client and other files are generated in SRC.

3: Create the directory required by the cluster

mkdir -p/usr/local//usr/local/clustermkdir7000mkdir  7001mkdir7002mkdir7003mkdir7004mkdir  7005

4: Modify configuration file redis.conf
Cp/usr/local/redis3.0/redis.conf/usr/local/cluster
VI redis.conf
# #修改配置文件中的下面选项

Pidfile/var/run/redis. 7000  7000  #个性化daemonize yescluster-enabled Yescluster-config-file nodes. 7000 . conf #个性化cluster  the  "appendonly.7000.aof" #个性化

# #修改完redis These configuration entries in the. conf configuration file, copy the configuration file to the 7000/7001/7002/7003/7004/7005 directory, respectively.

cp /usr/local/cluster/redis.conf/usr/local/cluster/7000CP /usr/local/cluster/ redis.conf/usr/local/cluster/7001cp /usr/local/cluster/redis.conf/usr/local/cluster/7002  cp /usr/local/cluster/redis.conf/usr/local/cluster/7003CP /usr/local/cluster/ redis.conf/usr/local/cluster/7004cp /usr/local/cluster/redis.conf/usr/local/cluster/  7005

# #注意: After the copy is complete, change the label personalization parameters in the redis.conf file under the 7001/7002/7003/7004/7005 directory to the name of the corresponding folder.

5: Launch each of these 6 Redis instances
vi/usr/local/cluster/redis-start.sh
To add the following

 #!/bin/sh /usr/local/redis3. 0 /src/redis-server/usr/local/cluster/7000 /redis.conf &/usr/local/redis3. 0 /src/redis-server/usr/local/cluster/7001 /redis.conf &/usr/local/redis3. 0 /src/redis-server/usr/local/cluster/7002 /redis.conf &/usr/local/redis3. 0 /src/redis-server/usr/local/cluster/7003 /redis.conf &/usr/local/redis3. 0 /src/redis-server/usr/local/cluster/7004 /redis.conf &/usr/local/redis3. 0 /src/redis-server/usr/local/cluster/7005 /redis.conf & 

And then

chmod +x/usr/local/cluster/redis-start/usr/local/cluster/redis-start

# #启动之后使用命令查看redis的启动情况ps-ef|grep Redis

6: Execute redis Create cluster command to create cluster
Install Ruby because./REDIS-TRIB.RB is a ruby-executed script that requires a ruby environment
sudo apt-get install Ruby

In order to perform redis-trib.rb need to install gem Redis sudo gem install Redis There may be problems with the Great Firewall
You can go to https://rubygems.org/gems/redis/versions/3.2.2 to download the latest version.
Then use the command sudo gem install Redis-3.2.2.gem

 Cd/usr/local/redis3. 0 /src.  /REDIS-TRIB.RB Create--replicas 1  127.0  . 0.1 : 7000  127.0 . 0.1 : 7001  127.0 . 0.1 : 7002  127.0 . 0.1 : 7003  127.0 . 0.1 : 7004  127.0 . 0.1 : 7005  

The following output indicates success.

So the Redis-cluster cluster will start

7. View the current status of the cluster:
