本文介绍了第1行的错误1007（HY000）：无法创建数据库'mgsv'；数据库存在的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我将此项目转换为docker-compose项目，并按照他们的设置。看来我无法连接浏览器。
I converted this original project into a docker-compose project here and followed a their setup instructions. It seems that I am not able to connect with the browser.
包含数据库架构，如下所示：
The SQL file contains the database schema and looks like this:
CREATE DATABASE mgsv;
CREATE USER 'mgsv_user'@'localhost' IDENTIFIED BY 'mgsvpass';
GRANT SELECT, INSERT, CREATE, DROP ON mgsv.* TO 'mgsvuser'@'localhost';
use mgsv;
CREATE TABLE IF NOT EXISTS `userinfo` (
`id` int(10) NOT NULL AUTO_INCREMENT,
`email` text NOT NULL,
`hash` text NOT NULL,
`synfilename` text NOT NULL,
`annfilename` text NOT NULL,
`url` text NOT NULL,
`session_id` text NOT NULL,
`annImage` int(5) NOT NULL,
`create_on` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=3 ;
看起来像这样：
version: '3.1'
services:
db:
image: mysql
restart: always
environment:
- MYSQL_DATABASE=mgsv
- MYSQL_USER=mgsv_user
- MYSQL_PASSWORD=mgsvpass
- MYSQL_ROOT_PASSWORD=mysql123
volumes:
- ./mysql:/docker-entrypoint-initdb.d
www:
build: ./mGSV
restart: always
ports:
- 8080:8080
和包含PHP和所有其他工具的设置，看起来像这样。
And the Dockerfile contains PHP and all other tools setup and looks like this.
FROM php:5-apache
RUN apt-get update && apt-get install -y --no-install-recommends \
openjdk-7-jdk \
maven \
git \
&& rm -rf /var/lib/apt/lists/*
RUN git clone https://github.com/qunfengdong/mGSV.git
# Move the folder 'mgsv' to DocumentRoot of Apache web server. By default, the DocumentRoot of Apache is /var/www/ (speak to the system administrator to know the exact DocumentRoot).
RUN cd /var/www/html/mGSV \
&& mkdir tmp \
&& chmod -R 777 tmp
RUN cd /var/www/html/mGSV && sed -i.bak "s|'gsv'|'mgsv_user'|" lib/settings.php \
&& sed -i.bak "s|$database_pass = ''|$database_pass = 'mgsvpass'|" lib/settings.php \
&& sed -i.bak "s|cas-qshare.cas.unt.edu|localhost|" lib/settings.php
RUN cp /var/www/html/mGSV/Arial.ttf /usr/share/fonts/truetype/
#Do not understand
#7. Cleanup scripts are provided to drop database synteny and annotation tables, remove entries from database table 'userinfo' and delete the folder containing image files which are older than 60 days. This task is accomplished by cron job to run the cleanup script every day. To create a cron job, use the command below:
# shell> crontab -e
#At the last line of crontab, copy and paste the line below, and provide the exact path to mgsv/lib/cleanup.php
# 30 04 * * * /var/www/mgsv/lib/cleanup.php
#The script cleanup.php will be executed at 4:30 AM every morning.
#8. mGSV uses the mail function from PHP to send email to users. Speak to your system administrator to provide required information in the PHP configuration file called 'php.ini'.
#9. When installation completes, you can now open Install/index.php (i.e., http://<YOUR_SERVER_DOMAIN_NAME>/mgsv/Install/), which verifies prerequisites, database setup, and installation. YOUR_SERVER_DOMAIN_NAME refers to the domain name of your server.
RUN cd /var/www/html/mGSV/ws \
&& tar -xzf mgsv-ws-server.tar.gz
RUN cd /var/www/html/mGSV/ws/mgsv-ws-server \
&& mvn package
RUN cp -f /var/www/html/mGSV/ws/mgsv-ws-server/target/ws-server-1.0RC1-jar-with-dependencies.jar /var/www/html/mGSV/ws/
RUN cd /var/www/html/mGSV/ws \
&& echo "mgsv_upload_url=http://localhost/mgsv" > config.properties \
&& echo "ws_publish_url=http\://localhost\:8081/MGSVService" >> config.properties \
&& java -jar ws-server-1.0RC1-jar-with-dependencies.jar &
#To stop the web service
#shell> ps aux | grep ws-server-1.0RC1-jar-with-dependencies.jar
#*Note the process id from the output*
#shell> kill -9 <process id>
这是我得到的输出：

我不确定我是否在文件或数据库配置位于。
I am not quite sure whether I did a mistake in the docker-compose.yml file or database configuration inside the Dockerfile.
有机会，有人知道我的失踪吗？
By any chance, do anyone know what I am missing?
预先感谢您
推荐答案
您在 docker-compose.yml 文件中为mysql容器设置了环境变量 MYSQL_DATABASE = mgsv 。创建并启动mysql容器后，它将自动创建数据库 mgsv ，并允许用户 mgsv_user （由环境变量 MYSQL_USER = mgsv_user 指定 >）进行访问。有关详细信息，您可以在中查找 mysql 映像。
You have environment variable "MYSQL_DATABASE=mgsv" set for the mysql container in your docker-compose.yml file. When the mysql container is created and started, it will have database mgsv created automatically, and allow user mgsv_user (specified by environment variable "MYSQL_USER=mgsv_user") to access it. For details, you may check official documentation for the mysql image.
您应该做的是，从SQL文件中删除语句 CREATE DATABASE mgsv; 。 ，或将该语句更改为 如果不存在，则创建数据库mgsv; 。您可能还需要调整该SQL文件中的其他语句（例如，在这种情况下不需要创建用户）。
What you should do it is, either delete statement "CREATE DATABASE mgsv;" from your SQL file, or change that statement to "CREATE DATABASE IF NOT EXISTS mgsv;". You may also need to adjust other statements in that SQL file (e.g., user creation is not needed in this case).
