Let's talk about the detailed process of building Gitlab

With the vigorous development of software development, version control tools are increasingly used. As a distributed version control system, Git has become the tool of choice for developers. As a web-based Git code warehouse management tool, Gitlab is also favored by developers. This article will share the detailed process of building Gitlab and solutions to some common problems, let us complete the process together.

1. Install Gitlab

The following are the steps to install Gitlab:

1. Install the required dependencies, such as curl, openssh-server, postfix, etc.:

sudo apt-get update
sudo apt-get install curl openssh-server ca-certificates postfix

2. Add Gitlab’s official repository:

curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh | sudo bash

3. Install Gitlab (Gitlab-ce is used here):

sudo apt-get install gitlab-ce

4. Enter the IP address of the server in the browser Or domain name, such as:

http://your_server_ip_or_domain

如果一切正常，您应该在屏幕上看到Gitlab的欢迎页面。

2. Configure Gitlab

The following are the steps to configure Gitlab:

1. Edit the Gitlab configuration file:

sudo vi /etc/gitlab/gitlab.rb

2. Check if the external URL is correct:

external_url 'http://your_domain_or_ip_address'

3. If you are using an SSL certificate, use the following command:

sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/gitlab/ssl/your_domain.key -out /etc/gitlab/ssl/your_domain.crt

然后在配置文件中添加以下行：

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

4. If you want to change the default ssh port, use The following command:

sudo vi /etc/ssh/sshd_config

将以下行添加到文件的底部：

Port your_new_ssh_port

注意：确保您的防火墙已正确配置以允许您的新ssh端口。

5. After saving the changes, please reconfigure Gitlab:

sudo gitlab-ctl reconfigure

6. Restart Gitlab:

sudo gitlab-ctl restart

3. Solutions to common problems

The following are some common problems and solutions:

1. Problem: Unable to access the Gitlab welcome page

解决方案：确保您使用的是正确的IP地址或域名，并且您已正确安装和配置Gitlab。

2. Problem: Unable to log in to Gitlab

解决方案：确保您使用正确的用户名和密码，并且您的帐户已正确配置。如果您遇到仍然无法登录的问题，请检查您的日志文件以获取更多信息。

3. Problem: Unable to connect to Gitlab using ssh

解决方案：如果您使用默认的ssh端口22，则可能需要更改该端口。请参阅上面的配置Gitlab部分以了解如何更改ssh端口。

4. Problem: Unable to connect to Gitlab via https

解决方案：如果您使用的是自签名证书，请确保您的证书已正确安装并且您的浏览器已信任该证书。如果您使用的是公共证书，请确保证书的所有权和有效性。
