Symfony 1.4：在维护模式下清除缓存时出错答案

【问题标题】：Symfony 1.4: Error Clearing Cache in Maintenance ModeSymfony 1.4：在维护模式下清除缓存时出错
【发布时间】：2021-11-12 21:18:27
【问题描述】：

我正在使用旧的 Symfony 1.4 站点，此时升级不是一个选项。

为了部署站点，我创建了一个任务，首先将站点置于维护模式，执行一些其他工作（下拉代码等），然后清除缓存，然后再尝试将站点恢复原状在线（退出维护模式）。

但是，我发现当我尝试在维护模式下清除缓存时，它失败了，我反而在命令行上重新获得了网页。有解决此问题的建议吗？

【问题讨论】：

根据您的网络服务设置方式，缓存目录和文件可能由与您运行 cli 实用程序的用户不同的用户拥有。这通常是有效的网络服务器用户。请参阅@Greg 评论。这本质上是一个棘手的问题，所以我使用部署工具解决了这个问题，以 root 身份删除目录。
执行缓存清除时无需将网站置于维护模式 (./symfony project:disable)。
我将其置于维护模式以将其从运行状况检查中删除，因此我的负载均衡器无法为站点提供服务（三个副本之一）。我可以尝试在此之外清除缓存，但我过去曾遇到过这样的问题。

【解决方案1】：

我不是 symfony 1.4 专家/爱好者，但您是否尝试过从缓存目录中删除所有内容？你可以这样做：

rm -r /path/to/the/dir/with/cache/*

（记住 * 在路径末尾删除目录 inside 缓存目录）
