1. 下载镜像

• 下载最新发布版本

docker pull redis

或在官网查看 https://redis.io 哪个是最后稳定版本(latest stable version)

image.png

• 下载5.0.7

docker pull redis:5.0.7

• 查看镜像信息

�docker history redis:5.0.7
docker image inspect redis:5.0.7

2. 创建redis参数文件

2.1 下载参数文件模板

https://raw.githubusercontent.com/antirez/redis/5.0/redis.conf

• 建立本地存放数据文件的路径

mkdir -p ~/Docker/redis/data
cd ~/Docker/redis/data

2.2 修改参数文件

mv ~/Downloads/redis.conf redis.conf.orig
vi redis.conf.orig

• 注释 bind 127 ,解绑local ip

#bind 127.0.0.1
bind 127.0.0.1

• 确保daemonize,为no(默认) ,否则通过docker -d 方式不能启动redis, (非docker方式,需要改为yes实现后台启动)

daemonize no

• 外网访问

#protected-mode yes
protected-mode no

• 设定密码

#requirepass foobared
requirepass welcome1

• 使用aof持久化方式

#appendonly no
appendonly yes

3. 创建Dockerfile

cd ~/Docker/redis/

vi Dockerfile

FROM redis:5.0.7
MAINTAINER mayongzhi@163.com
COPY ./data/redis.conf.orig /usr/local/etc/redis/redis.conf
EXPOSE 6379
CMD [ "redis-server", "/usr/local/etc/redis/redis.conf" ]

4. 创建镜像

docker build -t myredis:5.0.7 .

myzmac:redis myz$ docker build -t myredis:5.0.7 .

myzmac:redis myz$ 

myzmac:redis myz$ docker images myredis

4. 创建容器

docker run -e TZ="Asia/Shanghai"  -h myredis --name myredis507  -m 64m  -p 63791:6379 -v /Users/myz/Docker/redis/data:/data -d myredis:5.0.7

5. 连接使用

• 进入容器连接

myzmac:redis myz$ docker exec -it myredis bash
root@myredis:/data# redis-cli -a welcome1
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
127.0.0.1:6379> set nm myz
OK
127.0.0.1:6379> get nm
"myz"
127.0.0.1:6379> save 
OK
127.0.0.1:6379> 
root@myredis:/data# 

• 外部连接

redis-cli -h 1.1.1.2 -p  63791 -a welcome1

• 使用python操作python 示例1

pip3 install redis

myzmac:redis myz$ cat demo.py
import redis
redis_pool = redis.ConnectionPool(host='127.0.0.1', port= 63791, password= 'welcome1', db= 0)
redis_conn = redis.Redis(connection_pool= redis_pool)
v = redis_conn.get('nm')
print (v)
name_dict = {
    'nm1' : 'mmm',
    'nm2' : 'yyy',
    'nm3' : 'zzz'
}
redis_conn.mset(name_dict)
m = redis_conn.mget('nm1', 'nm1','nm3')
print(m)

myzmac:redis myz$ 
myzmac:redis myz$ python3 demo.py 
b'myz'
[b'mmm', b'mmm', b'zzz']

• 使用python操作python 示例2(使用Pipe方式 速度更快)

myzmac:redis myz$ cat demo2.py 
#!/usr/bin/env python
# -*- coding: utf-8 -*-
"""
__title__ = 'demo'
__author__ = 'Jason Ma'
__mtime__ = '2020/2/2'
__version__= ' '
"""

import redis
import time

redis_pool = redis.ConnectionPool(host='127.0.0.1', port= 63791, password= 'welcome1', db= 1)
r = redis.Redis(connection_pool= redis_pool)
r.flushdb()

# start = time.time()
# for i in range(10000):
#     r.set('nm_'+str(i),i)
# print(r.dbsize())
# end = time.time()
# print ("执行用时:",end-start,"秒")

redis_pool = redis.ConnectionPool(host='127.0.0.1', port= 63791, password= 'welcome1', db= 2)
r = redis.Redis(connection_pool= redis_pool)
pipe = r.pipeline()
r.flushdb()

start = time.time()
for i in range(100000):
    pipe.set('nm_'+str(i),i)

pipe.execute()
cnt = r.dbsize()
end = time.time()

print ("写入",cnt,"条用时:",end-start,"秒")
myzmac:redis myz$ python3 demo2.py
