在Ubuntu中配置GitLab可参考以下步骤：
sudo apt update，sudo apt upgrade -y。sudo apt install -y curl openssh-server ca-certificates postfix。curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh | sudo bash。sudo EXTERNAL_URL="http://your-server-ip" apt install gitlab-ce，将your-server-ip替换为实际IP或域名。/etc/gitlab/gitlab.rb，设置external_url等参数，如external_url 'http://your-domain.com'，还可配置邮件服务等。sudo gitlab-ctl reconfigure。sudo ufw allow http，sudo ufw allow https，sudo ufw allow ssh。
