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 -c -n
[root@redis-server ~]# redis-benchmark -h localhost -p -c -n

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 monitor
先开启一个终端1，用于redis监控
[root@redis-server ~]# redis-cli -h localhost -p monitor
OK
1504689350.635365 [ 127.0.0.1:] "COMMAND"
1504689361.944610 [ 127.0.0.1:] "set" "a" ""
1504689369.782029 [ 127.0.0.1:] "get" "a"
然后在开启一个redis终端2进行操作
[root@redis-server ~]# redis-cli -p
127.0.0.1:> set a
OK
127.0.0.1:> get a
""
127.0.0.1:>
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 info
备注：该命令也可以在redis终端里面进行查询
[root@redis-server ~]# redis-cli -h localhost -p info
