Ruby on rails 在运行精简的Rails应用程序（Redmine）中被拒绝的权限

我正在尝试使用Thin和nginx作为反向代理运行Redmine

My

/etc/thin2.1/redmine.yml

：

---
pid: /var/run/thin/redmine.pid
group: redmine
wait: 30
timeout: 30
log: /var/log/thin/redmine.log
max_conns: 1024
require: []

environment: production
max_persistent_conns: 512
servers: 4
daemonize: true
user: redmine
socket: /var/run/thin/redmine.sock
chdir: /var/www/projects.mydomain.tld

当我使用web浏览器访问网站时，我会看到一个

502坏网关

。这是

/var/log/thin/redmine.0.log的内容：

我不明白是什么导致了这个错误。
/var/run/thin/
中的
.pid
文件归root所有。我试图将所有权授予
redmine
和
thin
，但得到了相同的错误（无论如何，这些文件都是在thin重新启动时重新创建的）

我用rbenv安装了Ruby。我以root用户身份运行了
bundle安装
，这提示这样做
将破坏此计算机上所有非root用户的应用程序
。据我所知，这不应该是个问题，对吗

编辑：如果我在
/etc/thin2.1/redmine.yml
中将用户和组设置为
root
，则权限拒绝错误消失。我认为这是导致另一个错误的原因，但这个错误仍然存在。
对于
取消链接
文件权限过程实际上需要一个权限来写入该文件的目录

因此，要么给予
redmine
写入
/var/run/thin/
的权限，要么将PID和套接字放在其他地方——通常放在应用程序的共享
tmp
中，rails甚至会为它们创建目录。
你是什么意思？我是rails新手，但这不是瘦的任务吗？我没有明确运行Redmine…谢谢你的解释。对我来说，Thin与应用程序的用户一起管理其pid文件有点违反直觉。我把它们放在Redmine的
tmp
目录中，现在它可以正常工作了。
