Redis3.0 cluster Deployment (CentOS system)

(for the cluster to work, you need at least3a master node, where we're going to create6aRedisnode, where three primary nodes, three are slave nodes, correspondingRedisnode'sIpand port correspondence are as follows)192.168.1.160:7000
192.168.1.160:7001192.168.1.160:7002192.168.1.160:7003192.168.1.160:7004192.168.1.160:70051 : Download redis . Official website Download 3.0.0 version, before 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 # #Modify the following options in the configuration filePort 7000 daemonize Yes cluster-enabled Yes cluster-config-file nodes.conf cluster-node-timeout all appendonly Yes ##finished modifyingRedis.confThese configuration items in the configuration file are copied to the7000/7001/7002/7003/7004/7005directory belowcp/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 # #Note: To modify after the copy is complete7001/7002/7003/7004/7005directory belowredis.confin the filePortparameter, change to the name of the corresponding folder, respectively

5 : Start these 6 separately a redisExample

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 # # start using commands to view redis boot conditions PS- Ef|grep Redis as shown indicates successful start

6 : Performing RedisCreate a cluster command to create a 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

6.1you may get an error when executing the above command, because it is executed.Rubythe script that requiresRubythe EnvironmentError Content:/usr/bin/env:ruby:no such file or directoryso you need to installRubyenvironment, it is recommended to useYum Install Rubyinstallation

Yum Install Ruby

6.2and then perform the first6To create a cluster command, you may also get an error, indicating the missingRubyGemscomponents, usingYuminstallationError Content:./redis-trib.rb:24:in ' require ': no suchfile to load--RubyGems (Loaderror) from./redis-trib.rb:24

Yum Install RubyGems

6.3re-implementation of section6Step command, may also error, prompting cannot loadRedis, because of the lack ofRedisand theRubythe interface, usingGeminstallationError 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

6.4re-implementation of section6step of the command, normal executioninputYes, and then the configuration is complete. so farRedisThe cluster is built successfully! 7: UsingRedis-clicommand into the cluster environment
