我正在尝试使用Thin和nginx作为反向代理运行Redmine.

我的/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

当我使用我的网络浏览器访问该网站时,我得到了一个502 Bad Gateway.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.我试图给redmine和thin赋予所有权但是得到了相同的错误(这些文件在重新启动时重新创建).

我用rbenv安装了Ruby.我以root身份运行bundle install,这促使这样做会破坏此计算机上所有非root用户的应用程序.根据this answer这应该不是问题,应该吗？

编辑：如果我在/etc/thin2.1/redmine.yml中将用户和组设置为root,则权限被拒绝错误消失.我虽然它导致了另一个错误,但那个仍然存在.

解决方法:

对于unlink文件权限进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pids和socket放在别处 – 通常在app的共享tmp中,rails甚至为这些创建dirs.
