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 .
Sending build context to Docker daemon 127.5kB

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 -*-

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()
