简介
redis-trib.rb是官方提供的Redis Cluster的管理工具,无需额外下载,默认位于源码包的src目录下,但因该工具是用ruby开发的,所以需要准备相关的依赖环境
准备redis-trib.rb的运行环境
wget https://cache.ruby-lang.org/pub/ruby/2.5/ruby-2.5.1.tar.gz
tar xvf ruby-2.5.1.tar.gz
cd ruby-2.5.1/
./configure -prefix=/usr/local/ruby
make
make install
cd /usr/local/ruby/
cp bin/ruby /usr/local/bin
cp bin/gem /usr/local/bin
安装rubygem redis依赖
wget http://rubygems.org/downloads/redis-3.3.0.gem
gem install -l redis-3.3.0.gem

支持的操作如下:
1. create:创建集群
2. check:检查集群
3. info:查看集群信息
4. fix:修复集群
5. reshard:在线迁移slot
6. rebalance:平衡集群节点slot数量
7. add-node:添加新节点
8. del-node:删除节点
9. set-timeout:设置节点的超时时间
10. call:在集群所有节点上执行命令
11. import:将外部redis数据导入集群
