Redis cluster Installation Detailed steps

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These configuration entries in the redis.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 boot situation 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 step 6 to create the 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 Execute Step 6 command again, also error, prompt cannot load Redis because of missing Redis and Ruby interface, using gem to install

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 Step 6 command again, normal execution

Enter Yes, and 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
