redis集群的搭建
1.1 搭建集群需要的环境
搭建集群需要使用到官方提供的ruby脚本。
需要安装ruby的环境。
安装ruby
yum install ruby
yum install rubygems
redis集群管理工具redis-trib.rb
[[email protected] ~]# vim
[[email protected] redis-3.0.0]# cd src
[[email protected] src]# ll *.rb
-rwxrwxr-x. 1 root root 48141 Apr 1 07:01 redis-trib.rb
[[email protected] src]#
脚本需要的ruby包：
需要上传到linux服务。
安装ruby的包：
gem install redis-3.0.0.gem
[[email protected] ~]# gem install redis-3.0.0.gem
Successfully installed redis-3.0.0
1 gem installed

1.1 集群的搭建
第一步：创建6个redis实例，端口号从7001~7006
第二步：修改redis的配置文件
1、修改端口号
2、打开cluster-enable前面的注释。
还有几个配置：
##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
第三步：把创建集群的ruby脚本复制到redis-cluster目录下。
显示行数：
到命令模式下，输入 :set number
第四步：启动6个redis实例
先创建个脚本：
第五步：创建集群。
在脚本执行命令：
