篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了如何在 Alma Linux 8 上安装 GitLab?相关的知识,希望对你有一定的参考价值。
GitLab 是一款免费的开源 DevOps 软件,它附带多种工具,可在单个应用程序中开发、保护和操作软件。它提供免费的无限存储库和无限的协作者。它主要用于托管 Git 存储库,并具有其他与开发相关的功能,例如问题跟踪。它与 Github 和 Bitbucket 非常相似,允许个人和团队与他人远程共享代码。
GitLab 有四个主要版本:
- GitLab 社区版- 免费、开源和自托管。
- GitLab 企业版- 自托管和付费附加功能。
- GitLab.com - 免费和 SaaS。
- GitLab.io - 由 GitLab Inc. 管理的私有 GitLab 实例。
在这篇文章中,我们将解释如何在 Alma Linux 8 上安装 GitLab CE。
先决条件
- 运行 Alma Linux 8 的服务器。
- 使用您的服务器 IP 指向的有效域名。
- 在服务器上配置了 root 密码。
添加 GitLab CE 存储库
默认情况下,GitLab 包不包含在 Alma Linux 默认存储库中。因此,您需要将 GitLab 官方存储库添加到您的系统中。您可以下载并添加以下脚本以添加 GitLab 存储库。
curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | bash
您将获得以下输出:

Generating yum cache for gitlab_gitlab-ce-source...
The repository is setup! You can now install packages.
您可以使用以下命令验证已安装的存储库:
cat /etc/yum.repos.d/gitlab_gitlab-ce.repo
您将获得以下输出:
[gitlab_gitlab-ce]
name=gitlab_gitlab-ce
baseurl=https://packages.gitlab.com/gitlab/gitlab-ce/el/8/$basearch
repo_gpgcheck=1
gpgcheck=1
enabled=1
gpgkey=https://packages.gitlab.com/gitlab/gitlab-ce/gpgkey

您还可以使用以下命令列出 GitLab 存储库:
dnf repolist
您将获得以下输出:
repo id repo name
appstream Rocky Linux 8 - AppStream
baseos Rocky Linux 8 - BaseOS
extras Rocky Linux 8 - Extras
gitlab_gitlab-ce gitlab_gitlab-ce
gitlab_gitlab-ce-source gitlab_gitlab-ce-source
在 Alma Linux 8 上安装 GitLab CE
此时,GitLab 存储库已在您的系统上创建。您现在可以通过运行以下命令来安装 GitLab CE:
dnf install gitlab-ce -y
安装 GitLab CE 后,您将获得以下输出:
It looks like GitLab has not been configured yet; skipping the upgrade script.

配置 GitLab CE
接下来,您需要在 GitLab 配置文件中定义您的域名。为此,请编辑 GitLab 配置文件:
nano /etc/gitlab/gitlab.rb
使用您的域名更改以下行:
external_url http://gitlab.example.com
保存并关闭文件,然后使用以下命令重新配置 GitLab:
gitlab-ctl reconfigure
重新配置 GitLab CE 后,您将获得以下输出:
Notes:
Default admin account has been configured with following details:
Username: root
Password: You didnt opt-in to print initial root password to STDOUT.
Password stored to /etc/gitlab/initial_root_password. This file will be cleaned up in first reconfigure run after 24 hours.
NOTE: Because these credentials might be present in your log files in plain text, it is highly recommended to reset the password following https://docs.gitlab.com/ee/security/reset_user_password.html#reset-your-root-password.
gitlab Reconfigured!
您现在可以使用以下命令检查 GitLab CE 的状态:
gitlab-ctl status
您将获得以下输出:

要停止 GitLab,请运行以下命令:
gitlab-ctl stop
要启动 GitLab,请运行以下命令:
gitlab-ctl start
完成后,您可以继续下一步。
配置防火墙
接下来,您需要允许 HTTP 服务通过 firewalld。您可以使用以下命令允许它:
firewall-cmd --permanent --add-service=http
接下来,重新加载 firewalld 守护进程以应用更改:
systemctl reload firewalld
配置防火墙后,您可以继续下一步。
访问 GitLab CE
在访问 GitLab CE 之前,使用以下命令检索 GitLab 根密码:
cat /etc/gitlab/initial_root_password
您应该在以下输出中看到 GitLab CE 根密码:
# WARNING: This value is valid only in the following conditions
# 1. If provided manually (either via `GITLAB_ROOT_PASSWORD` environment variable or via `gitlab_rails[initial_root_password]` setting in `gitlab.rb`, it was provided before database was seeded for the first time (usually, the first reconfigure run).
# 2. Password hasnt been changed manually, either via UI or via command line.
#
# If the password shown here doesnt work, you must reset the admin password following https://docs.gitlab.com/ee/security/reset_user_password.html#reset-your-root-password.
Password: XIlQ4/J7oQ49ZdNuGZto3f5vEJGHZJSTRSIuYL9z0/k=
# NOTE: This file will be automatically deleted in the first reconfigure run after 24 hours.
现在,打开您的 Web 浏览器并使用 URL http://gitlab.example.com访问 GitLab Web 界面。您将被重定向到 GitLab 登录页面:
提供您的 root 用户名和密码,然后单击登录按钮。您应该在以下页面上看到 GitLab Web 界面:
配置 GitLab 备份
GitLab 还允许您创建 GitLab 实例的备份。要创建 GitLab 实例的备份,请运行以下命令:
gitlab-rake gitlab:backup:create
创建备份后,您将获得以下输出:

默认情况下,GitLab 备份存储在/var/opt/gitlab/backups。您可以通过编辑位于/etc/gitlab/gitlab.rb的 GitLab 配置文件中的设置来更改备份路径。
您可以使用以下命令验证生成的备份:
ls /var/opt/gitlab/backups
您将获得以下输出:
1646997191_2022_03_11_14.8.2_gitlab_backup.tar
重置 GitLab 根密码
如果您忘记了 GitLab 管理员密码,则可以使用以下命令轻松重置它:
gitlab-rake "gitlab:password:reset"
系统将要求您设置新密码,如下所示:
Enter username: root
Enter password:
Confirm password:
Password successfully updated for user with username root.
