# [GitLab]安装

## 硬件配置

[官方推荐]((https://docs.gitlab.com/ce/install/requirements.html#hardware-requirements))的硬件配置为：

1. `2 cores CPU`
2. `8GB RAM`

## 安装

进入[gitlab/gitlab-ce](https://packages.gitlab.com/gitlab/gitlab-ce)查询

首先安装依赖项

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

```

然后安装`gitlab-ce`

```
# 当前是ubuntu 16.04
$ sudo apt-get install gitlab-ce
```

*也可以下载.deb包后安装*

```
$ sudo dpkg -i gitlab-ce_12.3.5-ce.0_amd64.deb

Thank you for installing GitLab!
GitLab was unable to detect a valid hostname for your instance.
Please configure a URL for your GitLab instance by setting `external_url`
configuration in /etc/gitlab/gitlab.rb file.
Then, you can start your GitLab instance by running the following command:
  sudo gitlab-ctl reconfigure

For a comprehensive list of configuration options please see the Omnibus GitLab readme
https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md
```

## 系统配置

打开文件`/etc/gitlab/gitlab.rb`，修改`external_url`为自己的地址

```
$ sudo cat /etc/gitlab/gitlab.rb | grep external_url
[sudo] password for zj: 
Sorry, try again.
[sudo] password for zj: 
##! For more details on configuring external_url see:
##external_url 'http://gitlab.example.com'
external_url 'http://localhost:8800'
...
...
```

重新进行`gitlab`配置

```
$ sudo gitlab-ctl reconfigure
