wercker.com 连接到 MySQL 数据库
wercker.com connect to MySQL database
背景
我正在尝试使用 http://wercker.com. I have created my own Docker repo https://hub.docker.com/r/consynki/yii2/ 为 Yii2 应用程序构建一些自动化测试，它提供了一个简单的 LAMP 堆栈。
我正在使用 Docker 存储库作为我的 wercker.yml 文件中的框，通过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

问题
问题是，当我 运行 使用 wercker CLI wercker build 我的构建时，它无法连接到 mysql。在尝试 运行 'Create database' 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，因为我可以通过 ssh 进入它并且 运行 mysql -uroot -e "SHOW DATABASES;"
编辑 我当前正在进行的工作 wercker lamp 模板可在 https://github.com/levi-putna/php-cli-template
获得
请求
我知道 wercker.com 比较新，没有很多文档。但我希望有人能为我提供一个示例，说明如何在 wercker 测试 运行.
中使用 mysql
编辑 - 使用 Wercker 服务
我也尝试使用 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，但应该足以开始测试。
我更新了我的 wercker.yml 以添加 mariadb 服务。简化了我的步骤，让数据库连接正常工作。
box: consynki/yii2
services:
- id: mariadb
# your credentials for Docker Hub
username: $USERNAME
password: $PASSWORD

MYSQL_USER: admin
MYSQL_PASSWORD: test123
build:
steps:
- script:

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;"
我似乎仍然遇到与我原来的方法相同的错误。 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，我还看到了一些额外的日志消息。

您可以使用 Wercker 准备的现成 MySQL 服务器，而不是设置您自己的服务器。这将确保它在调用之间持续存在。
说明
好的，我使用@Tal 的建议成功建立了一个数据库连接。 Wercker docks 仅提供了一个使用 MariaDB 的示例，幸运的是 MySQL 有一个 docker 容器，其工作方式几乎与 MariaDB 版本完全相同。
我将新容器作为服务添加到我的 wercker.yml。
services:
- id: mysql
# your credentials for Docker Hub
username: $USERNAME
password: $PASSWORD
tag: latest
# set the required environment variable
env:
MYSQL_ROOT_PASSWORD: mypassword
MYSQL_DATABASE: test_database
MYSQL_USER: admin
MYSQL_PASSWORD: test123
然后我能够使用 MySQL 服务公开的环境变量在我的 Wercker 步骤中连接到数据库。
- script:
name: Create database
code: mysql -h$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;"
我还可以使用 PHP 中的环境变量来连接到数据库。
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 是这样的，你可以在 https://github.com/levi-putna/php-cli-template 看到我的完整模板。这只是一个示例，您可能想要清理 PHP 连接到数据库的步骤和方式，但这是一个很好的起点。
答案 - 完整 wercker.yml

您可以使用 Wercker 准备的现成 MySQL 服务器，而不是设置您自己的服务器。这将确保它在调用之间持续存在。
说明
好的，我使用@Tal 的建议成功建立了一个数据库连接。 Wercker docks 仅提供了一个使用 MariaDB 的示例，幸运的是 MySQL 有一个 docker 容器，其工作方式几乎与 MariaDB 版本完全相同。
我将新容器作为服务添加到我的 wercker.yml。
services:
- id: mysql
# your credentials for Docker Hub
username: $USERNAME
password: $PASSWORD
tag: latest
# set the required environment variable
env:
MYSQL_ROOT_PASSWORD: mypassword
MYSQL_DATABASE: test_database
MYSQL_USER: admin
MYSQL_PASSWORD: test123
然后我能够使用 MySQL 服务公开的环境变量在我的 Wercker 步骤中连接到数据库。
- script:
name: Create database
code: mysql -h$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;"
我还可以使用 PHP 中的环境变量来连接到数据库。
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 是这样的，你可以在 https://github.com/levi-putna/php-cli-template 看到我的完整模板。这只是一个示例，您可能想要清理 PHP 连接到数据库的步骤和方式，但这是一个很好的起点。
答案 - 完整 wercker.yml
