The Nosql Redis database

1. Getting Started with Redis basics
2. Redis Application Advanced

First, the concept
Redis is an open source key-value, which is cache and storage, supports persistence, enables a meaningful high availability with sentinel, data structure server: String,list,hash,set, sorted Set,bitmap,hyperloglog
Four types of NoSQL genres:
Key-value Key-value: Memcached Redis
Documemtation Document Type: Mongodb
Columu Family column type: Hbase
Graph Image Type: neo4j

Two, install Redis

such as bind 127.0.0.1 192.168.100.6

IV. Application of Advanced
How Redis implements the authentication function, in the configuration file VI etc/redis.conf
Requirepass 123456 #123456为密码, restart effective
#redis-cli-h 192.168.100.6

Select 0, prompting for authentication information
