centos6.3上redmon和redis-live两款开源软件的使用情况，前者基于ruby，后者则基于python
　　=================================== 自带的
　　

    redis-server：Redis服务器的daemon启动程序
    redis-cli：Redis命令行操作工具。当然，你也可以用telnet根据其纯文本协议来操作
    redis-benchmark：Redis性能测试工具，测试Redis在你的系统及你的配置下的读写性能
    redis-stat：Redis状态检测工具，可以检测Redis当前状态参数及延迟状况




100个并发连接，100000个请求，检测host为localhost 端口为6379的redis服务器性能
/usr/local/redis/src/redis-benchmark -h localhost -p 6378 -c 100 -n 100000

99.96% <= 24 milliseconds
99.99% <= 25 milliseconds
100.00% <= 25 milliseconds
9408.22 requests per second



监控host为localhost，端口为6380，redis的连接及读写操作
/usr/local/redis/src/redis-cli -h localhost -p 6378 monitor

 
提供host为localhost，端口为6380，redis服务的统计信息
/usr/local/redis/src/redis-cli -h localhost -p 6378 info 

实时打印出host为localhost，端口为6380，redis实例的总体信息
/usr/local/redis/src/redis-stat port 6378 overview
