redis配置，状态监控与性能调优

本文主要介绍及演示一些Redis相关的状态监控和性能调优的命令及使用方法：

1、redis-benchmark

redis基准信息，redis服务器性能检测

例如：

检测redis服务器性能，本机6379端口的实例，100个并发连接，100000个请求

redis-benchmark -h localhost -p 6379 -c 100 -n 100000

[root@redis-server ~]#

2、redis-cli

例1：监控本机6379端口的实例的数据操作，redis的连接及读写操作

redis-cli -h localhost -p 6379 monitor

先开启一个终端1，用于redis监控

[root@redis-server ~]# redis-cli -h localhost -p 6379 monitor OK1504689350.635365 [0 127.0.0.1:57996] "COMMAND"1504689361.944610 [0 127.0.0.1:57996] "set" "a" "1"1504689369.782029 [0 127.0.0.1:57996] "get" "a"

然后在开启一个redis终端2进行操作

[root@redis-server ~]# redis-cli -p 6379127.0.0.1:6380> set a 1OK127.0.0.1:6380> get a "1"127.0.0.1:6380>

可以看到终端2上面进行的数据操作会在终端1上面被记录下来

例2：查询本机redis实例的信息，端口6379

redis-cli -h localhost -p 6379 info

备注：该命令也可以在redis终端里面进行查询
