1. 下载MySQL镜像
在Docker应用的『映像』中，下载『MySQL』:
2. 创建MySQL容器
- 在『高级设置』的环境变量设置中，注意添加『MYSQL_ROOT_PASSWORD』这个环境变量，其它不用动。
- 端口设置面板，注意映射2个宿主机端口：
- 存储空间设置一个存储数据的挂载点：
- 然后完成就可以了。
3. MySQL环境变量说明
下面引用该镜像官方对一些关键环境变量的说明，按需使用。『https://registry.hub.docker.com/_/mysql/』
When you start the mysql image, you can adjust the configuration of the MySQL instance by passing one or more environment variables on the docker run command line. Do note that none of the variables below will have any effect if you start the container with a data directory that already contains a database: any pre-existing database will always be left untouched on container startup.
See also https://dev.mysql.com/doc/refman/5.7/en/environment-variables.html for documentation of environment variables which MySQL itself respects (especially variables like MYSQL_HOST, which is known to cause issues when used with this image).
3.1. MYSQL_ROOT_PASSWORD
This variable is mandatory and specifies the password that will be set for the MySQL root superuser account. In the above example, it was set to my-secret-pw.
3.2. MYSQL_DATABASE
This variable is optional and allows you to specify the name of a database to be created on image startup. If a user/password was supplied (see below) then that user will be granted superuser access (corresponding to GRANT ALL) to this database.
3.3. MYSQL_USER, MYSQL_PASSWORD
These variables are optional, used in conjunction to create a new user and to set that user's password. This user will be granted superuser permissions (see above) for the database specified by the MYSQL_DATABASE variable. Both variables are required for a user to be created.
Do note that there is no need to use this mechanism to create the root superuser, that user gets created by default with the password specified by the MYSQL_ROOT_PASSWORD variable.
3.4. MYSQL_ALLOW_EMPTY_PASSWORD
This is an optional variable. Set to a non-empty value, like yes, to allow the container to be started with a blank password for the root user. NOTE: Setting this variable to yes is not recommended unless you really know what you are doing, since this will leave your MySQL instance completely unprotected, allowing anyone to gain complete superuser access.
3.5. MYSQL_RANDOM_ROOT_PASSWORD
This is an optional variable. Set to a non-empty value, like yes, to generate a random initial password for the root user (using pwgen). The generated root password will be printed to stdout (GENERATED ROOT PASSWORD: .....).
3.6. MYSQL_ONETIME_PASSWORD
Sets root (not the user specified in MYSQL_USER!) user as expired once init is complete, forcing a password change on first login. Any non-empty value will activate this setting. NOTE: This feature is supported on MySQL 5.6+ only. Using this option on MySQL 5.5 will throw an appropriate error during initialization.
3.7. MYSQL_INITDB_SKIP_TZINFO
By default, the entrypoint script automatically loads the timezone data needed for the CONVERT_TZ() function. If it is not needed, any non-empty value disables timezone loading.
