Redis3.0 cluster Deployment (CentOS 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's IP and port correspondence is as follows) 192.168.1.160:7000
192.168.1.160:7001192.168.1.160:7002192.168.1.160:7003192.168.1.160:7004192.168.1.160:7005 1: Download Redis. Download 3.0.0 version, previous 2. Several versions do not support cluster mode: HTTP://DOWNLOAD.REDIS.IO/RELEASES/REDIS-3.0.0.TAR.GZ2: Upload Server, unzip, compile

TAR-ZXVF redis-3.0.0.tar.gz mv redis-3.0.0.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  ## After modifying these configuration items 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 respectively     &nbSp

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/cl uster/7002 redis-server redis.conf cd/usr/local/cluster/7003 redis-server redis.conf cd/usr/local/cluster/7004 Redi S-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 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 1 192.168.1.160:7000 192.168.1.160:7001 192.168.1.160:700 2 192.168.1.160:7003 192.168.1.160:7004 192.168.1.160:7005

6.1 You may get an error when executing the above command, because it is a ruby script that requires Ruby environment 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, may also error, hint missing RubyGems component, use Yum install error content:./redis-trib.rb:24:in ' require ': no suchfile to load--rubygems (Loaderror) from./redis-trib.rb:24

Yum Install RubyGems

6.3 Execute the 6th step of the command again, may also error, prompted not to load Redis, 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/ru Bygems/custom_require.rb:31:in ' Require ' from./redis-trib.rb:25

Gem Install Redis

6.4 Perform the 6th step command again, perform the normal input yes, and then configure the completion. This is where the Redis cluster is built successfully! 7: Use the REDIS-CLI command to enter the cluster environment
