安装使用docker，及docker-compose

    docker-compose.yml 内容如下

    1. version: '3.1'
    3. services:
    5.   redmine:
    6.     image: redmine
    7.     restart: always
    8.     ports:
    9.       - 4010:3000
    10.     environment:
    11.       REDMINE_DB_MYSQL: db
    12.       REDMINE_DB_PASSWORD: example
    13.       REDMINE_DB_ENCODING: utf8
    14.     volumes:
    15.       - ./data/redmine/file:/usr/src/redmine/files
    16.       - ./data/redmine/plugins:/usr/src/redmine/plugins
    17.       #- ./data/redmine/config/configuration.yml:/usr/src/redmine/config/configuration.yml
    18.       - ./data/redmine/ssh:/home/redmine/.ssh
    20.   db:
    21.     build: ./mysql
    22.     restart: always
    23.     ports:
    24.       - 3336:3306
    25.     environment:
    26.       MYSQL_ROOT_PASSWORD: example
    27.       MYSQL_DATABASE: redmine
    28.     volumes:
    29.       - ./data/mysql:/var/lib/mysql
    30.       - ./config/mysql:/etc/mysql/conf.d

    有一点需要注意，第17行处的注释，在首次运行 docker-compose up 后再打开注释。
