Redis installation and use basis

A redis official website installation online demo

1 wget http://download.redis.io/releases/redis-4.0.9.tar.gz

2 tar xzf redis-4.0.9.tar.gz

***ubuntu --->1 sudo mv ./redis-4.0.9 /usr/local/redis/

2 cd /usr/local/redis/

3 sudo make 4 sudo make test 5 sudo make install

6 sudo cp /usr/local/redis/redis.conf /etc/redis/ mobile configuration file

3 redis configuration information http://blog.csdn.net/ljphilp/article/details/52934933

Successful installation diagram

Install and run redis under windows (compressed package method) to add environment variables

1. Although redis is started above, as long as the cmd window is closed, the redis service will stop. So redis must be set as a service under windows.

2. Set service commands

redis-server --service-install redis.windows-service.conf --loglevel verbose

Two Redis server-side and client-side commands

The server-side command is redis-server
You can use help to view the help file
redis-server --help
ps aux | grep redis View the redis server process
sudo kill -9 pid Kill the redis server
sudo redis-server /etc/redis/redis.conf Specify the loaded configuration file

The client's command is redis-cli
You can use help to view the help file
redis-cli --help
Run test command ping
Connect to redis redis-cli select database select 10
The database has no name, there are 16 by default, which are identified by 0-15, and the first data is selected by default when connecting to redis

Check whether redis is started

Then click服务与应用 --> 服务 --> 查找redis的服务----- windows

Type ps -ef |grep redis-------------->linux

netstat -lntp | grep 6379

./etc/init.d/redis-server start

./etc/init.d/redis-server stop

./etc/init.d/redis-server restart

Open the path to install redis in cmd

1. Start the redis server in the local path and specify the configuration file
redis-server.exe redis-windows.conf
2. Start the redis client, specify the ip, port, and password

Run the redis-cli.exe in the folder in the local path to start the client
redis-cli.exe redis-cli after startup
redis-cli.exe shutdown

Three Click on the official website to view the command file http://redis.cn/commands.html

There are five types of values:

String, hash, list
Set set, ordered set zset

Four interact with python

There are 3 ways to install Redis https://github.com/andymccurdy/redis-py

The first type: enter the virtual environment pip install redis
The second type: enter the virtual environment easy_install redis
The third type: download the source code of the redis package from the official website-client, and install it using the source code
Execute wget step by step https://github.com/andymccurdy/redis-py/archive/master.zip
unzip master.zip
cd redis-py-master
sudo python setup.py install

from redis import *
"""这个模块中提供了StrictRedis对象(Strict严格)，⽤于连接redis服务器，并按照不同类型提供 了不同⽅法，进⾏交互操作
"""

sr = StrictRedis(host='localhost', port=6379, db=0)

"""
通过init创建对象，指定参数host、port与指定的服务器和端⼝连接，host默认为localhost，port默认为6379，db默认为0
"""
简写
sr=StrictRedis()


# 测试
from redis import *
if __name__=="__main__":
    try:
        #创建StrictRedis对象，与redis服务器建⽴连接
        sr=StrictRedis()
        #添加键name，值为test
        result=sr.set('name','test')
        #输出响应结果，如果添加成功则返回True，否则返回False
        print(result)
  
        result = sr.get('name')
        #输出键的值，如果键不存在则返回None
        print(result)

        result = sr.delete('name')
        #输出响应结果，如果删除成功则返回受影响的键数，否则则返回0
        print(result)

        #获取所有的键
        result=sr.keys()
        #输出响应结果，所有的键构成⼀个列表，如果没有键则返回空列表
        print(result)
    except Exception as e:
        print(e)
