LogFile "/usr/local/redis_cluster/log/"

Dir/usr/local/redis_cluster

Create a log folder under the Redis_cluster directory

./redis-server/usr/local/redis_cluster/7004/redis.conf

./redis-trib.rb Create--replicas 1 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 192.168.1.248:7003 192.168.1.248:7004 192.168.1.248:7005

./redis-trib.rb Create--replicas 1 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 192.168.1.249:7000 192.168.1.249:7001 192.168.1.249:7002

./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

(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. Installing Redis

Upload server, unzip, compile

TAR-ZXVF redis-3.2.1.tar.gz

CD redis-3.2.1

Make

After compilation

CD src

Copy

Redis-server

Redis-cli

Two files

2. Create a cluster directory

Set up the cluster corresponding folder Rediscluster

Build 6 subfolders in this folder for r7000, r7001, r7002, r7003, r7004, r7005

Paste the file you copied in the first step into the 6 subfolders above, and authorize

chmod 775 Redis-cli

chmod 775 Redis-server

Create a file in each subfolder redis.conf

File contents

Port 7000

cluster-enabled Yes

Cluster-config-file nodes.conf

Cluster-node-timeout 5000

AppendOnly Yes

Daemonize Yes

Bind 192.168.*.*
Protected-mode No

#这两个配置不加上, no other machine can access

Each file has a different port number, 7000, 7001, 7002, 7003, 7004, 7005, respectively.

3. Start each of the six Redis instances separately

to the corresponding folder to execute the

./redis-server redis.conf

Query the Redis process as follows

[Email protected] redis]# Ps-ef|grep Redis

Root 11092 1 0 14:35? 00:00:00./redis-server *:7000 [cluster]

Root 11296 1 0 14:46? 00:00:00./redis-server *:7001 [cluster]

Root 11403 1 0 14:53? 00:00:00./redis-server *:7002 [cluster]

Root 11441 1 0 14:55? 00:00:00./redis-server *:7003 [cluster]

Root 11486 1 0 14:57? 00:00:00./redis-server *:7004 [cluster]

Root 11532 1 0 14:59? 00:00:00./redis-server *:7005 [cluster]

Root 11545 11135 0 15:00 pts/2 00:00:00 grep--color=auto Redis

4. Create a Redis cluster

Execute under the SRC folder of the installation path

./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

[Email protected] 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

/usr/bin/env:ruby:no such file or directory

Error:/usr/bin/env:ruby:no such file or directory

Ruby's environment is required because it is a script that executes Ruby

Installing the ruby Environment

[[email protected] src]# Yum install Ruby

Execute the Create cluster command again

[Email protected] 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

From/usr/share/rubygems/rubygems/core_ext/kernel_require.rb:55:in ' require '

From./redis-trib.rb:25:in ' <main> '

Error cannot load such file-Redis (loaderror) ...

Missing RubyGems component, installing with Yum

[email protected] src]# Yum install RubyGems

Execute the Create cluster command again

[Email protected] 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

From/usr/share/rubygems/rubygems/core_ext/kernel_require.rb:55:in ' require '

From./redis-trib.rb:25:in ' <main> '

Missing Redis and Ruby interfaces, using GEM installation

Gem Install Redis

After you create the cluster command again, the cluster creation succeeds when prompted to enter Yes

[Email protected] src]#/redis-trib.rb create--replicas 1 192.168.8.21:7000 192.168.8.21:7001 192.168.8.21:7002 192.168.8.21:7003 192.168.8.21:7004 192.168.8.21:7005
