# Install GitLab under a relative URL **(FREE SELF)**
|
|
|
|
While it is recommended to install GitLab on its own (sub)domain, sometimes
|
|
this is not possible due to a variety of reasons. In that case, GitLab can also
|
|
be installed under a relative URL, for example `https://example.com/gitlab`.
|
|
|
|
This document describes how to run GitLab under a relative URL for installations
|
|
from source. If you are using an Omnibus package,
|
|
[the steps are different](https://docs.gitlab.com/omnibus/settings/configuration.html#configuring-a-relative-url-for-gitlab). Use this guide along with the
|
|
[installation guide](installation.md) if you are installing GitLab for the
|
|
first time.
|
|
|
|
There is no limit to how deeply nested the relative URL can be. For example you
|
|
could serve GitLab under `/foo/bar/gitlab/git` without any issues.
|
|
|
|
Note that by changing the URL on an existing GitLab installation, all remote
|
|
URLs will change, so you'll have to manually edit them in any local repository
|
|
that points to your GitLab instance.
|
|
|
|
The list of configuration files you must change to serve GitLab from a
|
|
relative URL is:
|
|
|
|
- `/home/git/gitlab/config/initializers/relative_url.rb`
|
|
- `/home/git/gitlab/config/gitlab.yml`
|
|
- `/home/git/gitlab/config/puma.rb`
|
|
- `/home/git/gitlab-shell/config.yml`
|
|
- `/etc/default/gitlab`
|
|
|
|
After all the changes you need to recompile the assets and [restart GitLab](../administration/restart_gitlab.md#installations-from-source).
|
|
|
|
## Relative URL requirements
|
|
|
|
If you configure GitLab with a relative URL, the assets (JavaScript, CSS, fonts,
|
|
images, etc.) will need to be recompiled, which is a task which consumes a lot
|
|
of CPU and memory resources. To avoid out-of-memory errors, you should have at
|
|
least 2GB of RAM available on your system, while we recommend 4GB RAM, and 4 or
|
|
8 CPU cores.
|
|
|
|
See the [requirements](requirements.md) document for more information.
|
|
|
|
## Enable relative URL in GitLab
|
|
|
|
NOTE:
|
|
Do not make any changes to your web server configuration file regarding
|
|
relative URL. The relative URL support is implemented by GitLab Workhorse.
|
|
|
|
---
|
|
|
|
Before following the steps below to enable relative URL in GitLab, some
|
|
assumptions are made:
|
|
|
|
- GitLab is served under `/gitlab`
|
|
- The directory under which GitLab is installed is `/home/git/`
|
|
|
|
Make sure to follow all steps below:
|
|
|
|
1. (Optional) If you run short on resources, you can temporarily free up some
|
|
memory by shutting down the GitLab service with the following command:
|
|
|
|
```shell
|
|
sudo service gitlab stop
|
|
```
|
|
|
|
1. Create `/home/git/gitlab/config/initializers/relative_url.rb`
|
|
|
|
```shell
|
|
cp /home/git/gitlab/config/initializers/relative_url.rb.sample \
|
|
/home/git/gitlab/config/initializers/relative_url.rb
|
|
```
|
|
|
|
and change the following line:
|
|
|
|
```ruby
|
|
config.relative_url_root = "/gitlab"
|
|
```
|
|
|
|
1. Edit `/home/git/gitlab/config/gitlab.yml` and uncomment/change the
|
|
following line:
|
|
|
|
```yaml
|
|
relative_url_root: /gitlab
|
|
```
|
|
|
|
1. Edit `/home/git/gitlab/config/puma.rb` and uncomment/change the
|
|
following line:
|
|
|
|
```ruby
|
|
ENV['RAILS_RELATIVE_URL_ROOT'] = "/gitlab"
|
|
```
|
|
|
|
1. Edit `/home/git/gitlab-shell/config.yml` and append the relative path to
|
|
the following line:
|
|
|
|
```yaml
|
|
gitlab_url: http://127.0.0.1/gitlab
|
|
```
|
|
|
|
1. Make sure you have copied the supplied init script and the defaults file
|
|
as stated in the [installation guide](installation.md#install-init-script).
|
|
Then, edit `/etc/default/gitlab` and set in `gitlab_workhorse_options` the
|
|
`-authBackend` setting to read like:
|
|
|
|
```shell
|
|
-authBackend http://127.0.0.1:8080/gitlab
|
|
```
|
|
|
|
NOTE:
|
|
If you are using a custom init script, make sure to edit the above
|
|
GitLab Workhorse setting as needed.
|
|
|
|
1. [Restart GitLab](../administration/restart_gitlab.md#installations-from-source) for the changes to take effect.
|
|
|
|
## Disable relative URL in GitLab
|
|
|
|
To disable the relative URL:
|
|
|
|
1. Remove `/home/git/gitlab/config/initializers/relative_url.rb`
|
|
|
|
1. Follow the same as above starting from 2. and set up the
|
|
GitLab URL to one that doesn't contain a relative path.
|
|
|
|
<!-- ## Troubleshooting
|
|
|
|
Include any troubleshooting steps that you can foresee. If you know beforehand what issues
|
|
one might have when setting this up, or when something is changed, or on upgrading, it's
|
|
important to describe those, too. Think of things that may go wrong and include them here.
|
|
This is important to minimize requests for support, and to avoid doc comments with
|
|
questions that you know someone might ask.
|
|
|
|
Each scenario can be a third-level heading, e.g. `### Getting error message X`.
|
|
If you have none to add when creating a doc, leave this section in place
|
|
but commented out to help encourage others to add to it in the future. -->
