gitlab self hosted server
使用 gitlab 官网提供的 Omnibus packages 安装方式比较简单：
ubuntu 安装方式
1. Install and configure the necessary dependencies
sudo apt-get update
sudo apt-get install -y curl openssh-server ca-certificates
Next, install Postfix to send notification emails. If you want to use another solution to send emails please skip this step and configure an external SMTP server after GitLab has been installed.
sudo apt-get install -y postfix
During Postfix installation a configuration screen may appear. Select 'Internet Site' and press enter. Use your server's external DNS for 'mail name' and press enter. If additional screens appear, continue to press enter to accept the defaults.
2. Add the GitLab package repository and install the package
Add the GitLab package repository.
curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ee/script.deb.sh | sudo bash
Next, install the GitLab package. Change https://gitlab.example.com to the URL at which you want to access your GitLab instance. Installation will automatically configure and start GitLab at that URL.
For https:// URLs GitLab will automatically request a certificate with Let's Encrypt, which requires inbound HTTP access and a valid hostname. You can also use your own certificate or just use http://.
sudo EXTERNAL_URL="https://gitlab.example.com" apt-get install gitlab-ee
sudo apt install gitlab-ee也可以替换成先下载deb 然后用 sudo dpkg -i xxx.deb 来安装
https://packages.gitlab.com/gitlab/gitlab-ee
中可以选择对应的版本下载。
3. 配置ip地址
出了在2中安装时设置环境变量，external_url 也可以在配置文件中修改：
sudo vim /etc/gitlab/gitlab.rb
13 external_url 'http://192.168.100.75' # ip
