gitlab环境准备
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 postfix4.在放镜像的路径操作如下命令安装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
Selecting previously unselected package gitlab-ce.
(Reading database ... 133527 files and directories currently installed.)
Preparing to unpack gitlab-ce_13.2.3-ce.0_amd64 .deb ...

It looks like GitLab has not been configured yet; skipping the upgrade script.

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
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://192.168.0.104’
book@100ask:/$ cd /etc/gitlab/
book@100ask:/etc/gitlab$ ls
gitlab.rb gitlab-secrets.json trusted-certs
book@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 reconfigure8.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
