即使我可以使用PMA以相同的凭据进行操作,Symfony似乎也无法连接到数据库。
docker-compose.yml:
version: '3'
services:
apache:
build: .docker/apache
container_name: sf4_apache
ports:
- 80:80
volumes:
- .docker/config/vhosts:/etc/apache2/sites-enabled
- .:/home/wwwroot/sf4
depends_on:
- php
mysql:
image: mysql
command: "--default-authentication-plugin=mysql_native_password"
container_name: sf4_mysql
restart: always
volumes:
- ./data/db/mysql:/var/lib/mysql
environment:
MYSQL_ROOT_PASSWORD: root
MYSQL_DATABASE: sf4
MYSQL_USER: sf4
MYSQL_PASSWORD: sf4
php:
build: .docker/php
container_name: sf4_php
volumes:
- .:/home/wwwroot/sf4
environment:
- maildev_host=sf4_maildev
depends_on:
- maildev
- mysql
links:
- mysql
phpmyadmin:
image: phpmyadmin/phpmyadmin
container_name: sf4_phpmyadmin
environment:
PMA_HOST: mysql
PMA_PORT: 3306
ports:
- 8080:80
links:
- mysql
maildev:
image: djfarrelly/maildev
container_name: sf4_maildev
ports:
- 8001:80
Symfony .env:
DATABASE_URL=mysql://root:root@mysql:3306/sf4
我必须重新配置我的Doctrine文件吗?当前是默认值:
doctrine:
dbal:
# configure these for your database server
driver: 'pdo_mysql'
server_version: '5.7'
charset: utf8mb4
default_table_options:
charset: utf8mb4
collate: utf8mb4_unicode_ci
url: '%env(resolve:DATABASE_URL)%'
错误是:
驱动程序发生异常:找不到驱动程序
正如我所说,我可以使用root @ root凭据通过phpMyAdmin连接到数据库。
在连接到数据库之前,这是Connection.php文件中的变量$ this-> params:
["driver"]=>
string(9) "pdo_mysql"
["charset"]=>
string(7) "utf8mb4"
["url"]=>
string(32) "mysql://root:root@mysql:3306/sf4"
["host"]=>
string(5) "mysql"
["port"]=>
string(4) "3306"
["user"]=>
string(4) "root"
["password"]=>
string(4) "root"
["driverOptions"]=>
array(0) {
}
["serverVersion"]=>
string(6) "8.0.15"
["defaultTableOptions"]=>
array(2) {
["charset"]=>
string(7) "utf8mb4"
["collate"]=>
string(18) "utf8mb4_unicode_ci"
}
["dbname"]=>
string(3) "sf4"
答案 0 :(得分:1)
尝试一下:
doctrine:
dbal:
# configure these for your database server
driver: 'pdo_mysql'
server_version: '8.0.15'
charset: utf8mb4
default_table_options:
charset: utf8mb4
collate: utf8mb4_unicode_ci
url: '%env(resolve:DATABASE_URL)%'
mysql映像是mysql的最新版本。
php图像缺少pdo_mysql
驱动程序
应将其添加到Dockerfile中,如下所示:
RUN docker-php-ext-install pdo pdo_mysql zip
此后,必须使用以下命令重建图像:
docker-compose build

只需用 sf4_mysql 替换 mysql ,因为您必须在主机中应用容器名称(container_name:sf4_mysql) ==>
DATABASE_URL = mysql:// root:root @ mysql:3306 / sf4 通过 DATABASE_URL = mysql:// root:root @ sf4_mysql:3306 / sf4
