gitlab：网页只返回 502（哎呀，GitLab 响应时间太长了。）答案

【问题标题】：gitlab: webpages only return 502 (Whoops, GitLab is taking too much time to respond.)gitlab：网页只返回 502（哎呀，GitLab 响应时间太长了。）
【发布时间】：2021-07-23 21:26:10
【问题描述】：

我最近被任命为本地安装的新 gitlab 管理员，但我对 gitlab 的经验有限。不幸的是，前任管理员选择转向更绿色的牧场。

我们的安装如下： gitlab-ee-13.10.3-ee.0.el7.x86_64 继续运行 CentOS Linux 版本 7.9.2009（核心）

不幸的是，我继承了一个损坏的 gitlab，我似乎无法弄清楚如何解决我们的问题。

我们的 gitlab 网页只返回 502 糟糕，GitLab 响应时间过长。错误

gitlab-rails 控制台

失败并显示错误消息：

我在网上四处张望，但我找不到其他有这个问题的人。我还尝试删除有问题的 usage_data_api.yml 文件，但随后命令失败并显示新的错误消息（无法加载 --json 文件）

网上有文章描述如何使用浏览器启用禁用功能，但由于我们的网页都返回 502，我无法使用该选项。

话虽如此，我什至不知道上述错误消息是我们网页无法正常工作的根本原因，还是其他原因。

任何和所有帮助appriciated。

问候

【问题讨论】：

您找到解决方案了吗？我们从 gitlab-ce 13.10.3 到 13.12.15 也有类似的问题

标签： gitlab database-migration

【解决方案1】：

谨慎尝试，这对我们有用，但并不意味着推荐

我将本地文件夹与version we are upgrading to (13.12.15) 进行了比较，发现了许多其他功能标志。那些我搬走的人

我也把文件移走了

/opt/gitlab/embedded/service/gitlab-rails/config/initializers/json_validator_patch.rb

在 git 中不存在。

然后我就可以运行迁移了
