How to modify GitLab’s HTTP or HTTPS port

GitLab is an open source code hosting platform that usually uses the HTTP protocol to listen to port 80 by default. However, there are cases where you need to deploy GitLab to a different port. This article will introduce how to modify GitLab's HTTP or HTTPS port.

1. Modify HTTP port

First, enter the console of the GitLab server and execute the following command:

sudo vim /etc/gitlab/gitlab.rb

The editor will open the GitLab configuration file, Find the following line:

external_url 'http://example.com'

Modify it to:

external_url 'http://example.com:8080'

Save the modifications, and then execute the following command to make the configuration file take effect:

sudo gitlab-ctl reconfigure

GitLab will reload the configuration file and start Serve. Now, you can access GitLab by visiting http://example.com:8080.

2. Modify the HTTPS port

If your GitLab uses the HTTPS protocol to listen on port 443, you need to do some extra work to modify the HTTPS port. First, make sure you have configured an SSL certificate, otherwise please refer to the official documentation for configuration.

Next, enter the console of the GitLab server and execute the following command:

sudo vim /etc/gitlab/gitlab.rb

The editor will open the GitLab configuration file and find the following lines:

nginx['ssl_certificate'] = "/etc/gitlab/ssl/server.crt"
nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/server.key"

Modify them Save the changes for:

nginx['ssl_certificate'] = "/etc/gitlab/ssl/server.crt"
nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/server.key"
nginx['listen_port'] = 8443
nginx['listen_https'] = true

, and then execute the following command to make the configuration file take effect:

sudo gitlab-ctl reconfigure

Now, GitLab will listen on port 8443 using the HTTPS protocol. You can access GitLab by visiting https://example.com:8443.

Summary

You can easily modify GitLab's HTTP or HTTPS port by modifying the external_url and nginx options of the GitLab configuration file. It should be noted that before modifying the HTTPS port, make sure that the SSL certificate has been configured.
