This article mainly explains "the steps of installing and using Redis". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn the steps of installing and using Redis.

# download redis

Hadoop@dblab:/usr/local$ sudo wget http://download.redis.io/releases/redis-5.0.5.tar.gz

Hadoop@dblab:/usr/$ sudo mv redis-5.0.5.tar.gz. / redis

Local$ sudo tar-zxvf redis-5.0.5.tar.gz-C / usr/local

# authorize the redis directory to hadoop users

Hadoop@dblab:/usr/local$ sudo chown-R hadoop:hadoop. / redis

Hadoop@dblab:~$ cd / usr/local/redis/

Hadoop@dblab:/usr/local/redis$ sudo make # compilation

Hadoop@dblab:/usr/local/redis$ sudo make install # installation

# enable Redis server

Hadoop@dblab:/usr/local/redis$ pwd

/ usr/local/redis

Hadoop@dblab:/usr/local/redis$. / src/redis-server

# then create a new terminal and enter the following command to start the Redis client:

Hadoop@dblab:/usr/local/redis$. / src/redis-cli

127.0.0.1purl 6379 >

At this point, Redis is installed and running successfully, and then you can manipulate the Redis database.

# insert data

127.0.0.1 6379 > set Student:95001:Sname Li Yong

OK

127.0.0.1 6379 > set Course:1:Cname library

127.0.0.1 set Sc:95001:1:Grade 6379 >

127.0.0.1 6379 > set Course:8:Cname algorithm

# query data

127.0.0.1 purl 6379 > get Sc:95001:1:Grade

"92"

# Delete data

127.0.0.1 purl 6379 > del Course:8:Cname

(integer) 1

127.0.0.1 purl 6379 > get Course:8:Cname

(nil)

127.0.0.1 6379 > set Student:95001:Sname Li Yong

127.0.0.1 purl 6379 > get Student:95001:Sname

"\ xe6\ x9d\ x8e\ xe5\ x8b\ x87"

# solve the above problem of garbled Chinese content displayed in get key

Hadoop@dblab:/usr/local/redis$. / src/redis-cli-- raw

127.0.0.1 purl 6379 > get Student:95001:Sname
