安装Ruby和Gem

				?

									下载ruby

									wget https://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.8.tar.gz

									解压

									tar xvf ruby-2.3.8.tar.gz

									生成Makefile并且后面会被安装到/usr/local/ruby目录下

									./configure -prefix /usr/local/ruby

									编译

									make

									安装

									make install

									cd /usr/local/ruby

									cp bin/ruby /usr/local/bin/

									cp bin/gem /usr/local/bin/

安装Ruby和redis接口

下载

wget https://rubygems.org/downloads/redis-4.1.0.gem

安装

gem install -l redis-4.1.0.gem

将脚本移动到/usr/local/bin/下，方便直接执行

cp /usr/local/redis/src/redis-trib.rb /usr/local/bin/

启动Redis节点

8000端口配置文件模板，其余节点只有端口不同

				?

									# redis-8000.conf

									daemonize yes

									port 8000

									logfile "8000.log"

									dir "/server/redis_data"

									dbfilename "dump-8000.rdb"

									cluster-enabled yes

									cluster-config-file nodes-8000.conf

									cluster-require-full-coverage no

启动节点

				?

									redis-server redis-8000.conf 

									redis-server redis-8001.conf 

									redis-server redis-8002.conf 

									redis-server redis-8003.conf 

									redis-server redis-8004.conf 

									redis-server redis-8005.conf

一键开启

				?

									redis-trib.rb create --replicas 1 10.238.162.34:8000 10.238.162.34:8001\

									10.238.162.34:8002 10.238.162.34:8003\

									10.238.162.34:8004 10.238.162.34:8005

				?

									# redis-cli -p 8000 cluster info

									cluster_state:ok

									cluster_slots_assigned:16384

									cluster_slots_ok:16384

									cluster_size:3

									cluster_current_epoch:6

									cluster_my_epoch:1

									cluster_stats_messages_sent:695

									cluster_stats_messages_received:695

				?

									# redis-cli -p 8000 cluster nodes
