Redis命令
本地安装redis,通过安装目录下的redis客户端程序可以连接任意Redis服务(只要服务端是启动着的),命令 redis-cli -h ip -p port。如果服务端要求认证资格,可能还要输入用户名密码等参数。
Redis命令十分丰富,包括的命令组有Cluster、Connection、Geo、Hashes、HyperLogLog、Keys、Lists、Pub/Sub、Scripting、Server、Sets、Sorted Sets、Strings、Transactions一共14个redis命令组两百多个redis命令。这么多命令十分难记。或者我们需要连接服务器之后,在客户端可以通过比较灵活的一套逻辑快速找到想要的命令和命令使用说明。
1)先输入"help @"(也就是help+空格+@),然后按Tab键,客户端会提示所有的组。
2)通过1),可得出所有的group(组),然后想查哪个组下的命令,再用help @<group>,如connection是redis命令的一个group,即查看其下的命令为:help @connection。这样可得到该组下的所有命令。
3)根据2)所有命令都可以找到,help <command>(如 help keys)可以查看命令使用方法。
通过1)2)3)达到了通过比较灵活的一套逻辑快速找到想要的命令和命令使用说明的目的。这样无需借助其他资料,也可以得到一部命令字典。

Redis查看连接数量
- Linux
xshell连接linux系统
1)连接:Redis-cli -h ip -p port
2)授权:auth 密码
3)查看连接信息命令:client list
样例
[hw@helloworld ~]$ redis-cli -h 10.10.0.102 -p 6380
10.10.0.102:6380> auth hw@redis
OK

info可以查看整体信息,包括连接数
- window
基本上和linux系统一样,不同的是,需要在redis的安装目录下打开cmd,然后进行后续操作。
