拉取mysql5.7版本镜像

docker pull mysql:5.7	

运行镜像

docker run --name mysql 

-v /mydata/mysql/data:/var/lib/mysql\ 

-v /mydata/mysql/conf:/etc/mysql\

 -v /mydata/mysql/log:/var/log/mysql\  
 
-e MYSQL_ROOT_PASSWORD=root\   

-p 3306:3306 -d mysql:5.7

参数
-v /mydata/mysql/data:/var/lib/mysql\ 将数据文件挂载到主机 :前面的是主机目的地址：后面的是容器中的目录地址

-v /mydata/mysql/conf:/etc/mysql\ 将配置文件挂载到主机

-v /mydata/mysql/log:/var/log/mysql\ 将日志文件挂载到主机

查看运行的容器

docker ps
[root~]# docker p
CONTAINER ID   IMAGE                COMMAND                  CREATED        STATUS                    PORTS                    NAMES
6f2e3327238f   mysql:5.7.26         "docker-entrypoint.s…"   6 months ago   Exited (0) 6 months ago                            mysql

进入到交互式mysql中

docker exec -it 6f2e3327238f /bin/bash

修改mysql的配置文件 设置字符编码等
vim /mydata/mysql/conf/my.cnf

[client]
default-character-set=utf8
[mysql]
default-character-set=utf8
[mysqld]
init_connect='SET collation_connection = utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8
skip-character-set-client-handshake
skip-name-resolve

重启mysql docker restart mysql

安装redis

拉取镜像

docker pull redis

启动redis
创建文件夹
mkdir -p /mydata/redis/conf
touch /mydata/redis/conf/redis.conf

docker run -p 6379:6379  --name redi -v /mydata/redis/data:/data\
-v /mydata/redis/conf/redis.conf:/etc/redis/redis.conf\
-d redis redis-server /etc/redis/redis.conf  --privileged=true

注意，最新版的命令不同，容器内的conf文件的位置变为了/usr/local/etc/redis/redis.conf

mkdir -p /mydata/redis/conf
touch /mydata/redis/conf/redis.con

进入到redis控制台

docker exec -it redis redis-cli

开启redis持久化
vim /mydata/redis/conf/redis.conf
加入

bind 0.0.0.0 开启远程权限
appendonly yes 开启aof持久化

重启redis
docker restart redis
