Redis是否安装

1、Redis对否安装（安装好了会出现下面对应的代码）

[lk@localhost /]$ whereis redis-cli
redis-cli: /usr/local/bin/redis-cli
[lk@localhost /]$
[lk@localhost /]$ whereis redis-server
redis-server: /usr/local/bin/redis-server

说明已经安装好了，如果不知道怎么安装，告诉你一个简单的方法，一步就可以把php、php-redis拓展，redis-server,redis-cli这三个装起来。

接着就把redis-server加入快捷键，谁都不想每次敲一长串地址：

2、启动Redis

输入代码

redis-server &

[lk@localhost /]$ redis-server &
[]
