我正在尝试使用http://wercker.com为Yii2应用构建一些自动化测试。我创建了自己的Docker repo https://hub.docker.com/r/consynki/yii2/，它提供了一个简单的LAMP堆栈。
我正在使用Docker repo作为我的wercker.yml文件中的框，只需几个简单的步骤来设置我的应用程序，初始化数据库，然后运行我的phpunit测试
box: consynki/yii2
build:
steps:
- script:
name: Update enviroment dependencies
code: |-
curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/bin/ --filename=composer

sudo cp ./config/example.lan.conf /etc/apache2/sites-available/example.lan.conf
sudo a2ensite example.lan.conf
sudo cp -fr ./config/hosts /etc/hosts
sudo service apache2 restart
- script:
name: Create database
code: |-
mysql -uroot -e "SHOW DATABASES;"
mysql -uroot -e "CREATE DATABASE IF NOT EXISTS test"
- script:
name: PHPUnit integration tests
code: |-
./vendor/bin/phpunit --configuration phpunit.xml
问题是，当我使用wercker CLI wercker build运行我的构建时，它无法连接到mysql。尝试运行“创建数据库”步骤时，我不断收到以下连接错误ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)。
- script:
name: Create database
code: |-
mysql -uroot -e "SHOW DATABASES;"
mysql -uroot -e "CREATE DATABASE IF NOT EXISTS test"
我知道docker容器有一个mysql连接，因为我可以插入它并运行mysql -uroot -e "SHOW DATABASES;"
修改我目前正在进行的工作wercker灯模板位于https://github.com/levi-putna/php-cli-template
我知道wercker.com相对较新，而且没有很多文档。但我希望有人可以提供一个如何在wercker测试运行中使用mysql的例子。
我还尝试使用Wercker MariaBD服务进行连接，它不完全是MySQL，因此不是对我的生产环境的真正测试，但应该足以让测试开始。
我更新了我的wercker.yml以添加mariadb服务。简化了我的步骤，让数据库连接工作正常。
box: consynki/yii2
services:
- id: mariadb
# your credentials for Docker Hub
username: $USERNAME
password: $PASSWORD
tag: latest
# set the required environment variable
env:
MYSQL_ROOT_PASSWORD: mypassword
MYSQL_DATABASE: test_database
MYSQL_USER: admin
MYSQL_PASSWORD: test123
build:
steps:
- script:
name: Create database
code: |-
mysql -h $MARIADB_PORT_3306_TCP_ADDR -P $MARIADB_PORT_3306_TCP_PORT -u $MYSQL_USER -p test123 -v
mysql -h $MARIADB_PORT_3306_TCP_ADDR -P $MARIADB_PORT_3306_TCP_PORT -u $MYSQL_USER -p test123 -e "SHOW DATABASES;"
我似乎仍然遇到与原始方法相同的错误。 ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
在wercker步骤退出后，我也看到了一些额外的日志消息。

您可以使用由Wercker准备的现成MySQL服务器，而不是自己设置。这将确保它在两次通话之间保持不变。
答案 1 :(得分：1)
好的，我设法使用@Tal的建议来建立数据库连接。 Wercker停靠站仅提供使用MariaDB的示例，幸运的是MySQL有一个docker容器，其工作方式与MariaDB版本几乎完全相同。
我将新容器作为服务添加到我的wercker.yml中。
services:
- id: mysql
# your credentials for Docker Hub
username: $USERNAME
password: $PASSWORD
tag: latest
# set the required environment variable
env:
MYSQL_ROOT_PASSWORD: mypassword
MYSQL_DATABASE: test_database
MYSQL_USER: admin
MYSQL_PASSWORD: test123
然后，我可以使用MySQL服务公开的环境变量在Wercker步骤中连接到数据库。
- script:
name: Create database
code: mysql -h$MYSQL_PORT_3306_TCP_ADDR -P$MYSQL_PORT_3306_TCP_PORT -uroot -p$MYSQL_ENV_MYSQL_ROOT_PASSWORD -e "CREATE DATABASE IF NOT EXISTS test;"
我也可以使用PHP中的环境变量来连接数据库。
class SampleTest extends PHPUnit_Framework_TestCase
{
public function testSetupWorking()
{
$this->assertEquals(true, true);
$this->assertFalse(false);
}
public function testDatabase()
{
$hostname = $_SERVER["MYSQL_PORT_3306_TCP_ADDR"];
$username = 'root';
$password = $_SERVER["MYSQL_ENV_MYSQL_ROOT_PASSWORD"];
$database = $_SERVER["MYSQL_ENV_MYSQL_DATABASE"];
try {
$dbh = new PDO("mysql:host=$hostname;dbname=$database", $username, $password);
$this->assertFalse(false);
} catch (PDOException $e) {
echo $e->getMessage();
$this->assertFalse(true, $e->getMessage());
}
}
}
我的完整wercker.yml看起来像这样，你可以在https://github.com/levi-putna/php-cli-template看到我的完整模板。这只是一个例子，您可能希望清理PHP连接到数据库的步骤和方式，但这是一个很好的起点。
