通过Docker部署MySQL服务可同时存在多个版本，只用拉取不同的版本且区分Docker启动MySQL容器的端口号及数据卷即可。

MySQL 5.7

# 拉取镜像
docker pull mysql:5.7.25
# 提前准备好配置文件及挂载目录
mkdir /usr/local/server /usr/local/server/mysql5.7 /usr/local/server/mysql5.7/conf/ /usr/local/server/mysql5.7/data/
touch /usr/local/server/mysql5.7/conf/my.cnf
vi /usr/local/server/mysql5.7/conf/my.cnf
# 将配置文件写入my.cnf

# Docker启动命令
docker run -d \
--name mysql5.7 \
--restart=always \
-p 3306:3306 \
-m 1024M \
-v /usr/local/server/mysql5.7/conf:/etc/mysql \
-v /usr/local/server/mysql5.7/data:/var/lib/mysql \
-e MYSQL_ROOT_PASSWORD=123456 \
mysql:5.7.25

# 方式一：进入容器检查MySQL是否启动成功
[root@localhost local]# docker exec -it mysql5.7 bash
root@a77116498bc5:/# mysql -uroot -p123456
