redis基础数据操作命令：

启动server:redis-server

本地连接：

➜ ~ redis-cli

127.0.0.1:6379>

链接远程redis:

redis-cli -h 192.168.2.210

[root@xsf001 ~]# redis-cli -h 192.168.1.103 -p 6379

redis 192.168.1.103:6379>

查看所有的key：keys *

清除所有key:flushall

修改key的名字：rename name name2

字符串相关命令

set name test

get name

入列顶部：lpush zylist '111aa'

入列尾部：rpush zylist 'ddd'

linsert zylist before 'bbb' 'addnew'

lrem zylist 4 'aaa'

出列顶部删除: lpop zylist

出列尾部删除：rpop zylist

llen

range zylist 0 -1
