Redis Cluster Deployment documentation (CENTOS6 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

: https://github.com/antirez/redis/archive/3.0.0-rc2.tar.gz

2: Upload server, unzip, compile

TAR-ZXVF redis-3.0.0-rc2.tar.gz

MV Redis-3.0.0-rc2.tar.gz redis3.0

cd/usr/local/redis3.0

Make

Make install

3: Create the directory required by the cluster

Mkdir-p/usr.local/cluster

Cd/usr.local/cluster

mkdir 7000

mkdir 7001

mkdir 7002

mkdir 7003

mkdir 7004

mkdir 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

Port 7000

Daemonize Yes

cluster-enabled Yes

Cluster-config-file nodes.conf

Cluster-node-timeout 5000

AppendOnly Yes

# #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/7000

cp/usr/local/cluster/redis.conf/usr/local/cluster/7001

cp/usr/local/cluster/redis.conf/usr/local/cluster/7002

cp/usr/local/cluster/redis.conf/usr/local/cluster/7003

cp/usr/local/cluster/redis.conf/usr/local/cluster/7004

cp/usr/local/cluster/redis.conf/usr/local/cluster/7005

# #注意: To modify the port parameter in the redis.conf file under the 7001/7002/7003/7004/7005 directory after the copy is complete, change the name of the corresponding folder

5: Start each of these 6 Redis instances separately

cd/usr/local/cluster/7000

Redis-server redis.conf

cd/usr/local/cluster/7001

Redis-server redis.conf

cd/usr/local/cluster/7002

Redis-server redis.conf

cd/usr/local/cluster/7003

Redis-server redis.conf

cd/usr/local/cluster/7004

Redis-server redis.conf

cd/usr/local/cluster/7005

Redis-server redis.conf

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

If the display indicates a successful start

6: Execute redis Create cluster command to create cluster

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

6.1 error occurs when executing the above command, because it is the Ruby script that is executed and requires the environment of Ruby

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

So you need to install Ruby's environment, it is recommended to use Yum install Ruby installation

Yum Install Ruby

6.2 Then perform the 6th step of the Create cluster command, also error, hint missing RubyGems component, use Yum to install

Error content:

./redis-trib.rb:24:in ' require ': No such file to load--rubygems (Loaderror)

From./redis-trib.rb:24

Yum Install RubyGems

6.3 Repeat the 6th step of the command, will also error, indicating that the Redis can not be loaded because of the lack of Redis and Ruby interface, using GEM installation

Error content:

/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in ' Gem_original_require ': No such file to load--Redis ( Loaderror)

From/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in ' require '

From./redis-trib.rb:25

Gem Install Redis

6.4 Execute the 6th step command again, normal execution

650) this.width=650; "Src=" Http://s4.51cto.com/wyfs02/M01/82/D7/wKiom1diXzvj48EiAAFXo1HJ8x4548.png-wh_500x0-wm_3 -wmp_4-s_2639981835.png "title=" 20150121173116437.png "alt=" Wkiom1dixzvj48eiaafxo1hj8x4548.png-wh_50 "/>

Enter Yes , and then the configuration is complete.

This is where the Redis cluster is built successfully!

7: Use the REDIS-CLI command to enter the cluster environment

Redis-cli-c-P 7000
