多克尔 - 撰写：数据库未初始化

Question

我有一个码头工人，撰写和MySQL的一个问题：

泊坞窗，compose.yml发生

version: '2' 
    services: 
    db: 
    image: mysql 
    volumes: 
     - "./sito/db/:/var/lib/mysql" 
    ports: 
     - "3306:3306" 
    restart: always 
    environment: 
     MYSQL_ROOT_PASSWORD: 

    app: 
    depends_on: 
     - db 
    image: eboraas/apache-php 
    links: 
     - db 
    ports: 
     - "80:80" 
    volumes: 
     - ./sito/:/var/www/html/ 

一个错误，当我撰写此容器：

Recreating phpapp_phpapache_1 
Attaching to phpapp_db_1, phpapp_phpapache_1 
db_1 | error: database is uninitialized and password option is not specified 
db_1 | You need to specify one of MYSQL_ROOT_PASSWORD, MYSQL_ALLOW_EMPTY_PASSWORD and MYSQL_RANDOM_ROOT_PASSWORD 
phpapache_1 | AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 172.30.0.3. Set the 'ServerName' directive globally to suppress this message 
phpapp_db_1 exited with code 1 
db_1 | error: database is uninitialized and password option is not specified 
db_1 | You need to specify one of MYSQL_ROOT_PASSWORD, MYSQL_ALLOW_EMPTY_PASSWORD and MYSQL_RANDOM_ROOT_PASSWORD

db_1 | You need to specify one of MYSQL_ROOT_PASSWORD, MYSQL_ALLOW_EMPTY_PASSWORD and MYSQL_RANDOM_ROOT_PASSWORD 
db_1 | error: database is uninitialized and password option is not specified 

但数据库没有密码。我该如何解决它？

Answer 1

看起来你将MYSQL_ROOT_PASSWORD设置为空。根据文档，它是必需的。

https://hub.docker.com/_/mysql/

MYSQL_ROOT_PASSWORD

这个变量是强制的，指定将用于MySQL根超级用户帐户被设定的密码。

Answer 2

根据documentation，而不是MYSQL_ROOT_PASSWORD:你必须使用-和=，你也应该使用 '密码' 的结果将是：

- MYSQL_ROOT_PASSWORD=some_password

在你的例子：

version: '2' 
    services: 
    db: 
    image: mysql 
    volumes: 
     - "./sito/db/:/var/lib/mysql" 
    ports: 
     - "3306:3306" 
    restart: always 
    environment: 
     - MYSQL_ROOT_PASSWORD=some_password
