Redmine

I installed Redmine 3.4.13 on CentOS 8, basically following https://linuxconfig.org/how-to-install-redmine-on-redhat-8.

Environment:
  Redmine version                3.4.13.stable
  Ruby version                   2.4.9-p362 (2019-10-02) [x86_64-linux]
  Rails version                  4.2.11.1
  Environment                    production
  Database adapter               PostgreSQL
SCM:
  Subversion                     1.10.2
  Git                            2.18.4
  Filesystem                     
Redmine plugins:
  clipboard_image_paste          1.13
  redmine_agile                  1.5.3
  redmine_importer               1.2.2
  redmine_lightbox2              0.4.5
  redmineup_tags                 2.0.8

Because of the plugins that my team wanted to use, we went with 3.4.x instead of the v4.x that the tutorial uses.

And because I had to downlevel Ruby, I used RVM to install that.

I also added the apache user to the redmine group:

cat /etc/group | grep redmine
wheel:x:10:myusername,redmine
redmine:x:1002:apache
rvm:x:1003:redmine

Right now, the 'Attachments directory writable' and 'Plugin assets directory writable (./public/plugin_assets)' both have red !'s, and I cannot upload any files.

Doesn't make a difference if SELinux is enforcing or disabled, owner on the folders (/opt/redmine/files & /opt/redmine/public/plugin_assets) are set recursively for redmine:redmine, I've even set the permissions to 777 with no change.

This post (https://www.redmine.org/boards/2/topics/58156) seems to indicate that the owner of /opt/redmine/config.ru is what determines what user Passenger runs as, this file is set to redmine:redmine.

Some log exports are:

I saw a post somewhere that said Passenger runs as 'nobody', but I don't know how to tell or how to check that.

Any thoughts or suggestions are appreciated.

Thanks!
