redis集群监控（redis-stat）

1. 环境

• redis集群版本: 3.2.1
• CentOS Linux release 7.2.1511 (Core)

2. 安装包

eventmachine-1.2.3.gem、redis-stat-0.4.14.gem、thin-1.5.1.gem、daemons-1.1.9.gem

gem下载网站：https://rubygems.org/gems
redis-stat下载：https://github.com/junegunn/redis-stat

3. 安装过程

本来想用redislive监控但是按照完发现使用的python redis模块不支持集群连接。

gem install eventmachine-1.2.3.gem
gem install thin-1.5.1.gem
gem uninstall daemons
gem install daemons-1.1.9.gem
