Redis客户端基本操作以及查看慢查询

1.连接

redis-cli.exe -h 127.0.0.1 -p 6379

2.验证密码

λ redis-cli.exe -h 127.0.0.1 -p 6379
127.0.0.1:6379> auth 密码

3. redis key值获取

keys * 获取当前数据下所有KEY值

get  key

select 2 切换到第二个数据库

127.0.0.1:6379> keys *
(empty list or set)
127.0.0.1:6379> keys *
1) "1234"
2) "2234"
127.0.0.1:6379> get 1234
"1234"
127.0.0.1:6379> select 2
OK

　　4. info命令

redis Info 命令基本语法如下：

redis 127.0.0.1:6379> INFO [section]

　　

127.0.0.1:6379[2]> INFO

5. slowlog get 10    慢查询语句， 在上一个节中有讲过

参照 http://www.cnblogs.com/huamei2008/p/8850047.html

6.  Redis自身性能压测：

命令：

　　redis-benchmark -p 6379 -c 20000 -n 50000

　　　　-h 表示IP

　　　　-p 表示端口

　　　　-c 表示连接数

　　　　-n表示请求数

　　　　-t 后面跟请求方式， 如get
