> docker方式部署主要场景：测试环境，用户内网环境，不方便联网下载rpm包的生产环境

# 1. 下载镜像 #

docker pull mysql:8.0.22

# 2. 创建数据文件夹 #

mkdir -p /apps/mysql/data  /apps/mysql/conf   /apps/myql/files

*  /apps/mysql/data 用于存放各种数据文件、日志文件等
 *  /apps/mysql/conf 映射配置文件
 *  /apps/myql/files 当指定了外部配置文件与外部存储路径时，也需要指定 /var/lib/mysql-files的外部目录，不然启动会报 on ‘/var/lib/mysql-files’ No such file or directory

# 3. 创建自己的my.cnf配置文件 #

在文件夹 /apps/mysql/conf 创建mysql配置文件my.cnf

这里主要主要，几个重要文件存放的地址，这里统一存放/var/lib/mysql下，即映射到主机目录 /apps/mysql/data

# 3. 启动镜像 #

docker run -p 3306:3306 --restart=always --name mysql8 -v /apps/mysql/conf/my.cnf:/etc/mysql/my.cnf -v /apps/mysql/files:/var/lib/mysql-files -v /apps/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=Mypd12345_  -d mysql:8.0.22

一般正常情况，启动没问题，mysql镜像版本 8.0.22

完 !
