每次在 Google App Engine 上构建后运行 Laravel 数据库迁移答案

【问题标题】：Run Laravel Database Migration after every build on Google App Engine每次在 Google App Engine 上构建后运行 Laravel 数据库迁移
【发布时间】：2018-01-21 20:50:53
【问题描述】：

我在 GAE 上使用 MySQL 实例运行数据库运行 Laravel 5.5。我希望能够在每次构建后运行数据库迁移。我在 composer.json 的 post-install-cmd 上添加了命令“php artisan migrate”，但它似乎不起作用。

"post-install-cmd": [
        "chmod -R 755 bootstrap\/cache",
        "php artisan migrate",
        "php artisan cache:clear"
    ]

构建日志显示命令正在运行，但看起来那里的命令已取消。可能是什么问题？每次构建后如何运行迁移？任何帮助将不胜感激。

Here is screenshot of the build logs

SQL 错误：

ERROR: SQLSTATE[HY000] [2002] No such file or directory (SQL: select * from information_schema.tables where table_schema = My_DB_NAME and table_name = migrations) SQLSTATE[HY000] [2002] No such file or directory (SQL: select * from information_schema.tables where table_schema = My_DB_NAME and table_name = migrations) at /app/vendor/laravel/framework/src/Illuminate/Database/Connec‌tion.php:664, PDOException(code: 2002): SQLSTATE[HY000] [2002] No such file or directory at

【问题讨论】：

App Engine 日志位于由 GAE 应用程序过滤的 [日志记录选项卡](console.cloud.google.com/logs) 中。但是，如果您使用 Google 搜索错误 (laravel migrate SQLSTATE[HY000] [2002] No such file or directory)，您可能会找到一些对您也有帮助的答案。最后，here 有一个在 AppEngine 上运行 Laravel 的指南，你可能想看看。最后一个问题：您是否尝试过在 CloudSQL 实例中而不是在 AppEngine 部署中运行迁移命令？这行得通吗？
您提供的教程是我遵循的。该应用程序部署和运行良好，我可以连接到数据库，但迁移没有运行。对于在 CloudSQL 实例中运行迁移命令的部分，我该怎么做？
日志没有显示任何异常。同样的错误是我在部署时（它是一个构建错误）而不是应用程序错误。部署应用程序后工作正常，连接 SQL 实例（数据库），插入和检索数据。注意：我使用云控制台创建了一些虚拟表和数据
如果您在日志过滤器的第二个下拉菜单中按activity 过滤（或使用过滤器logName="projects/<PROJECT_ID>/logs/cloudaudit.googleapis.com%2Factivity" ），您还可以查看有关版本创建和更新的日志。您可以按照您所说的 tutorial 中的第 6 步在本地执行迁移。
我想在生产环境中而不是在本地运行迁移。在本地，它们运行良好。

【解决方案1】：

简答：

您需要在构建服务器上设置与生产数据库和 laravel 应用程序的云 SQL 连接。然后在代码部署到 google 后运行迁移。

如何安装 gcloud SDK？

https://github.com/GoogleCloudPlatform/continuous-deployment-bitbucket（检查 bitbucket-pipelines.yml）

如何设置谷歌云 SQL 代理？

https://cloud.google.com/sql/docs/mysql/connect-admin-proxy

如何设置 laravel 应用连接云端 SQL 代理？

将DB_HOST=127.0.0.1 和DB_PORT=3306 添加到.env 文件或您选择的任何端口。

运行迁移并享受！

长答案：

当您通过 SSH 连接到 GAE 实例时，您还看不到您的代码。它隐藏在另一层 Docker 容器之下。就我而言，有 5 个容器正在运行：gaeapp、cloudsql、api、nginx_proxy 和 fluentd_logger。如您所见，cloudsql 是容器之一，这意味着您的应用程序容器和 cloudsql 都必须构建才能相互连接。

最有可能发生的情况是包含您的代码的容器是在 cloundsql 之前配置的。因此，任何与数据库相关的命令，或者如果您在 laravel 启动期间执行了与数据库相关的代码，都会导致 SQLSTATE[HY000] [2002] No such file or directory 因为 /cloudsql/ directory/socket 尚未准备好。

因此，最直接的方法是从其他任何地方而不是从 GAE 运行迁移。可能也可以更新 GAE 的 docker config，但我不是很熟悉。

希望这会有所帮助！

【解决方案2】：

您需要将 --no-interaction 和 --force 标志添加到 migrate 命令。由于您在生产中，它会提示您输入 Y 或 N 来运行命令。

php artisan migrate  --no-interaction --force

【讨论】：

当我这样做时，我得到这个错误 ERROR: SQLSTATE[HY000] [2002] No such file or directory (SQL: select * from information_schema.tables where table_schema = My_DB_NAME and table_name = migrations) SQLSTATE [HY000] [2002] /app/vendor/laravel/framework/src/Illuminate/Database/Connection.php:664 中没有这样的文件或目录（SQL：从 information_schema.tables 中选择 *，其中 table_schema = My_DB_NAME 和 table_name = 迁移） , PDOException(code: 2002): SQLSTATE[HY000] [2002] 没有这样的文件或目录在
嗯，有些东西不在它应该在的地方。你能验证迁移文件在database/migrations 中吗？另外，My_DB_NAME 是否需要替换，还是您的数据库的实际名称？
出于安全原因，我在此评论中将数据库名称替换为 My_DB_NAME
检查storage/logs 中的日志文件，它是否包含此异常的完整堆栈跟踪？知道哪个文件不存在会很有帮助。
我的两分钱想法是在 Laravel 运行运行迁移之前，应用程序正在尝试访问迁移表以查看尚未运行的迁移批次。由于没有创建表（迁移也创建了迁移表），所以它返回错误，因为它找不到表
