python connection redis storage

The first is to install redis friends. This reference online article. He said fairly detailed.

But let me into a lot of the pit, that is, when the external network connection redis, always disconnect the positive, I thought it was a firewall problem, then check the information to know, because the default configuration file is not allowed redis external network access.

Easy installation refer to this article now.

Which says how to set up way back redis redis start there and start adding boot, and so on. I command lazy and do not fight.

Another article that is redis set the access password.

This article is also good. Redis to set up.

redis commonly used commands. redis-cli into the command line

　　　　　　　　View all key keys *

　　　　　　　　set key value [EX seconds] [PX milliseconds] [NX | XX] settings are stored inside the EX is the number of seconds

　　　　　　　　get key value can be displayed

Then redis is set outside the network visit.

https://www.cnblogs.com/grimm/p/11133226.html   reference to this.

Provided that you have put into port redis firewall program,

/sbin/iptables -I INPUT -p tcp --dport 6379 -j ACCEPT

/etc/rc.d/init.d/iptables save

changes redis.conf file

bind 127.0.0.1

protected-mode yes

Change

# bind 127.0.0.1

protected-mode no

set password

Requirepass foobared # 
requirepass yourpassword // Note here that can not have spaces forward

Then restart redis,
provided that you are now running redis
closed redis

Redis-cli the shutdown #

redis-cli is your installation path, that is, make install, you specify a path,
restart redis

Server-/opt/local/redis/redis-4.0.6/redis.conf Redis

Redis-Server is also installed in the path
so that access is provided outside the network is successful.

Then configure the redis be successful. This can be used to connect to the python.

Import Redis

# RES = redis.Redis (= Host 'you the IP', Port = 6379, password = PASSWORD) 
RES = Redis. StrictRedis (Host = 'you the IP ' , password = pASSWORD, DB =. 3, Port = 6379, decode_responses = True) # decoded and to be stored Chinese 
Print (RES) # this is a single redis connection 
# Print (the dir (redis )) 
res.set ( ' foo ' , ' I love you, China ' )
 Print (res.get ( ' foo ' ))

the pool = redis.ConnectionPool (= Host 'you the IP ' , password = PASSWORD, DB =. 3, Port = 6379, decode_responses = True)
 Print (the pool) # This is a connection pool 
R & lt redis.Redis = (= connection_pool the pool) 
r.set ( ' foo ' , ' I love you Beijing ' )
 Print (r.get ( ' foo ' ))
