Ubuntu安装redis缓存数据库

参考：http://blog.csdn.net/xiangwanpeng/article/details/54586087

1.在下载目录下

sudo wget http://download.redis.io/releases/redis-3.2.6.tar.gz

2.解压，并复制到/usr/local目录下

tar -zxvf redis-3.2.6.tar.gz
mv redis-3.2.6 /usr/local/

3.编译和安装

cd /redis
sudo make
sudo make install

4.在redis安装文件夹中修改文件redis.conf，使得redis在后台运行

vim redis.conf
#修改daemonize yes

5.启动redis

redis-server redis.conf
redis-cli -p 6379

6.安装redis desktop manager

按照 http://blog.csdn.net/u013410747/article/details/51706964 的步骤

安装deb安装包,需要依赖libicu52

在/etc/apt/目录下,先拷贝一份cp sources.list sources.list1

然后使用网易的源

deb http://mirrors.163.com/ubuntu/ trusty main restricted universe multiversedeb http://mirrors.163.com/ubuntu/ trusty-security main restricted universe multiversedeb http://mirrors.163.com/ubuntu/ trusty-updates main restricted universe multiversedeb http://mirrors.163.com/ubuntu/ trusty-proposed main restricted universe multiversedeb http://mirrors.163.com/ubuntu/ trusty-backports main restricted universe multiversedeb-src http://mirrors.163.com/ubuntu/ trusty main restricted universe multiversedeb-src http://mirrors.163.com/ubuntu/ trusty-security main restricted universe multiversedeb-src http://mirrors.163.com/ubuntu/ trusty-updates main restricted universe multiversedeb-src http://mirrors.163.com/ubuntu/ trusty-proposed main restricted universe multiversedeb-src http://mirrors.163.com/ubuntu/ trusty-backports main restricted universe multiverse

更新源

sudo apt-get update

sudo apt-get -f install libicu52

最后安装 redis-desktop-manager_0.8.3-120_amd64.deb

给redis设置密码，需要在redis.conf的配置文件中添加

requirepass xxxx

否则会报没有权限

(error) NOAUTH Authentication required

需要添加密码参数

redis-cli -p 6379 -a xxxx

redis默认的databases有16个，可以在配置文件中配置

databases 16

使用select来选择当前的库

127.0.0.1:6379> select 1
OK
127.0.0.1:6379[1]> select 0
OK

可以使用 keys *来查看redis中的数据，不过由于redis是单线程的，所以禁止在生产环境中使用keys命令

keys *

可以使用scan命令来替代keys命令

scan 0 match user* count 10

查看key的数据类型，不同的key所对应的命令不一样，否则会报 (error) WRONGTYPE Operation against a key holding the wrong kind of value

type XXXXX

zset的zcan命令，ZSCAN key cursor [MATCH pattern] [COUNT count]

比如

ZSCAN XXXX 0
