1.准备环境

gitlab只支持linux系统，本人在虚拟机下使用Ubuntu作为操作系统，gitlab镜像要使用和操作系统版本对应的版本，(ubuntu18.04,gitlab-ce_13.2.3-ce.0_amd64 .deb)

book@100ask:/$ lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 18.04.2 LTS
Release:	18.04
Codename:	bionic

2.下载gitlab

gitlab官网下载速度较慢且后续配置较麻烦，所以使用清华大学镜像，网址如下

Index of /gitlab-ce/ubuntu/pool/bionic/main/g/gitlab-ce/ | 清华大学开源软件镜像站 | Tsinghua Open Source Mirror

将gitlab镜像放入ubuntu某个路径下

3.安装前先安装依赖

安装邮件服务的时候会出现邮件配置，使用左右键和回车键选择确定、取消，弹出列表选项的时候，选择Internet Site

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

4.在放镜像的安装gitlab 

sudo pdkg -i gitlab-ce_13.2.3-ce.0_amd64 

5.安装成功提示

book@100ask:~$ sudo dpkg -i gitlab-ce_13.2.3-ce.0_amd64\ .deb

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

6.安装完配置网址

修改/etc/gitlab/gitlab.rb中的external_url配置访问页面，因为我是本地的虚拟机中安装的，所以可配置虚拟机的IP地址 external_url ‘http://localhost’

book@100ask:/$ cd /etc/gitlab/
book@100ask:/etc/gitlab$ ls
gitlab.rb  gitlab-secrets.json  trusted-certsbook@100ask:/etc/gitlab$ sudo vim gitlab.rb

external_url 'http://192.168.0.104'

7.配置完，初始化gitlab

sudo gitlab-ctl reconfigure

8.检查gitlab是否安装好，用如下命令检查

sudo gitlab-ctl status

正常提示如下 

book@100ask:/etc/gitlab$ sudo gitlab-ctl status

9.在本地window下的浏览器中输入http://192.168.0.104

10.重新设置密码

输入两次密码后，点击Change your password就可以了

11.登录使用root和刚设置的密码

12.正常登录显示
