Description

(Please note that I have not much experience with server administration, Plex, nginx, ...)

I have a Server with Plex (nginx enabled) and want to use gogs for some Git repositories. I installed gogs and configured it based on this: https://gogs.io/docs/intro/faqs.html#how-do-i-use-apache-2-with-reverse-proxy%3F .

Here some information:

app.ini

...
[server]
DOMAIN = localhost
HTTP_PORT = 3000
ROOT_URL = http://git.mydomain.com/
DISABLE_SSH = false
SSH_PORT = 22
OFFLINE_MODE = false
...

Additional Apache directives (Plesk)

RewriteEngine On

ProxyPreserveHost On
ProxyRequests off
ProxyPass / http://127.0.0.1:3000/
ProxyPassReverse / http://127.0.0.1:3000/

I use nginx too. Proxy mode is enabled in the Plesk settings.

I get several 404 errors while browsing through gogs on my server. One example is the "Dashboard" page. The server outputs:

Completed /index.html 404 Not Found in 3.496791ms
[D] Template: status/404

Same happens if I create a repository or click on a repository link.

Can you help me?

Not sure what is the problem exactly, but

1. DOMAIN = localhost looks wrong to me. You should put your domain here.
2. Gogs doesn't have index.html page, 404 is the correct response, it is not the URL for dashboard.

Hi,
thanks, now only index.html throws 404. Where do I need to add that file so it shows me that index.html?

[unknwon]

There is no index.html in Gogs.

[mcmatze]

But... do I have to create index.html? If I click on dashboard, I see that Gogs is searching for a non-existent index.html. What do I have to do to get that 404 away?

[unknwon]

That is your proxy problem which maybe always assume every time you visit / URL redirects to /index.html. I can't help with that..

Had the same issue as above but thanks to @unknwon hint, I managed to fix the problem very easily with the following extra code in the .htaccess folder as shown below.

DirectoryIndex disabled
RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteCond %{ENV:HTTPS} !=on
RewriteRule .* https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]
RewriteRule (.*) http://localhost:6000/$1 [P]

Note: I run mine in a subfolder and not subdomain i.e. https://example.com/gogs

To do this, just create a gogs folder (or whatever you want to call it) in your site root, then add the .htaccess file as shown above. Don't forget to update the ROOT_URL in the app.ini file to point to the full URL.

The actual thing which fixes it is, removing Directory Indexing i.e. removing index.html index.php and so forth from the config.

Hope this helps anyone else suffering the same issue.

@mcmatze

In your configuration,

RewriteEngine On

ProxyPreserveHost On
ProxyRequests off
ProxyPass / http://127.0.0.1:3000/
ProxyPassReverse / http://127.0.0.1:3000/

the line "RewriteEngine On“ is a silent misconfiguration. This means adding it to your system will not change any system behavior.
"RewriteEngine On" is introduced by Apache to explicitly enable all "RewriteRule" and "RewriteCond".
That is to say, unless you include multiple "RewriteRule" and "RewriteCond" parameters in your configuration, then leaving off "RewriteEngine" is a better choice.

More importantly, the default value of “RewriteEngine" is already an "off", so from a security side, deleting “RewriteEngine On” would be ideal.

The related Apache source code snippet:

run_rewritemap_programs(server_rec *s , apr_pool_t *p){
if (conf->state == ENGINE_DISABLED) { // usage of "RewriteEngine"
  return APR_SUCCESS; // early return
rewritemap_program(...); // usage of "RewriteRule" 
}
