编写redis.conf文件
这里有个坑，通常单独下载
redis都是把守护进程开启，但是这里须设置为no，因为daemonize yes，他的作用是开启守护进程模式，在该模式下，redis会在后台运行，并将进程pid号写入至redis.conf选项pidfile设置的文件中，此时redis将一直运行，除非手动kill该进程。但是在后面的命令中“-d”选项也是开启daemonize，只不过这是docker自家的方式。所以会产生冲突，这也是很多人不能正常启动的原因（当时在这个坑里呆了好久）
#注释掉，允许所有其他ip访问，真实使用最好坐下限制，只允许某些主机访问
#bind 127.0.0.1
# 若使用开机启动，生成pid，该项必须设置为诶yes，否则redis将不能够正常执行开机启动(systemctl start redis,执行后一直卡着，直到超时)
daemonize no
# 允许其他机器上的客户端连接当前redis，配置文件设置该项，则开机启动处就可以去掉--protected no
protected-mode no
#设置密码

编写 docker-compose.yml 文件

# network_mode: "host" # 如果需要容器使用宿主机IP(内网IP)，则可以配置此项
container_name: mysql # 指定容器名称，如果不设置此参数，则由系统自动生成
restart: unless-stopped # 设置容器自启模式
command: mysqld --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci # 设置utf8字符集
environment:
- TZ=Asia/Shanghai # 设置容器时区与宿主机保持一致
- MYSQL_ROOT_PASSWORD=123456 # 设置root密码
volumes:
- /etc/localtime:/etc/localtime:ro # 设置容器时区与宿主机保持一致
- ./mysql/data:/var/lib/mysql/data # 映射数据库保存目录到宿主机，防止数据丢失

安装docker docker-compose
curl -L https://get.daocloud.io/docker/compose/releases/download/1.27.4/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

]
}
systemctl daemon-reload
systemctl restart docker
创建并启动容器
docker-compose -f docker-compose.yml up -d
up选项启动容器，-d选项以守护模式运行，镜像如果没有，docker会先拉取镜像，有则直接创建并启动容器，注意文件运行前不能有其==同名容器==，还有须注意==防火墙设置==
如果要批量停止容器并清除容器，可以使用down命令
docker-compose -f docker-compose.yml down
如果要重新构建容器，可以使用--build选项
docker-compose -f docker-compose.yml up --build -d
