我想用php7.2.10-fpm、nginx和mysql 5.7建立一个小型docker环境,以便在其中运行laravel5.7。不幸的是,当我尝试从我的应用程序服务(尝试运行)连接到mysql时,出现了以下错误 docker-composer exec app php artisan migrate
):
In Connector.php
SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Name or service not known
PDO::__construct(): php_network_getaddresses: getaddrinfo failed: Name or service not known
想跑吗 docker-compose exec app mysql -u root -p
返回:error 2002(hy000):无法通过socket'/var/run/mysqld/mysqld.sock'连接到本地mysql服务器(2“没有这样的文件或目录”)
开始构建我的容器 docker-compose up --build
不会抛出错误。它说mysql正在运行并等待连接。我还通过删除并重新创建了所有图像 docker system prune --force --volumes
.
也许我在docker-compose.yml中遗漏了什么?

app.dockerfile文件:
FROM php:7.2.10-fpm
RUN apt-get update
RUN apt-get install -y libmcrypt-dev
RUN apt-get install -y mysql-client
RUN apt-get install -y libmagickwand-dev --no-install-recommends
RUN pecl install imagick
RUN docker-php-ext-enable imagick
RUN docker-php-ext-install pdo_mysql
RUN pecl install mcrypt-1.0.1
RUN docker-php-ext-enable mcrypt
RUN php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
RUN php -r "if (hash_file('SHA384', 'composer-setup.php') === '93b54496392c062774670ac18b134c3b3a95e5a5e5c8f1a9f115f203b75bf9a129d5daa8ba6a13e2cc8a1da0806388a8') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
RUN php composer-setup.php
RUN php -r "unlink('composer-setup.php');"
RUN mv composer.phar /usr/local/bin/composer
RUN apt-get install -y git
RUN apt-get update && apt-get install -y zlib1g-dev
RUN docker-php-ext-install zip
最后是我的.env文件:
DB_CONNECTION=mysql
DB_HOST=mysql
DB_PORT=3306
DB_DATABASE=shop
DB_USERNAME=shop_u
DB_PASSWORD=secret
更新 docker-compose images
列出以下容器:
+-----------------+-------------------+----------------+
| Container | Repository | ImageID |
+-----------------+-------------------+----------------+
| docker_app_1 | docker_app | a94dba376130 |
| docker_mysql_1 | docker_database | 563a026a1511 |
| docker_web_1 | docker_web | d9024ab40b73 |
+-----------------+-------------------+----------------+
跑步 ping docker_mysql_1
从 docker exec -it docker_app_1 bash
结果 bash: ping: command not found
.
跑步 ping docker_mysql_1
从 docker exec -it docker_web_1 bash
很好用。
