Git学习笔记8
Gitlab：
Gitlab是利用Ruby on Rails 一个开源的版本管理系统，实现一个自托管的git项目仓库，可通过web界面进行访问公开或私有的项目。
Gitlab安装：
安装之前，将虚拟机的内存改成了4个G。内存如果太小，会有502的错误提示信息。
在清华源中下载gitlab-ce最新的版本：
Index of /gitlab-ce/yum/el7/ | 清华大学开源软件镜像站 | Tsinghua Open Source Mirror
gitlab安装和配置：
wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-16.2.6-ce.0.el7.x86_64.rpm

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
Help us improve the installation experience, let us know how we did with a 1 minute survey:
https://gitlab.fra1.qualtrics.com/jfe/form/SV_6kVqZANThUQ1bZb?installation=omnibus&release=16-2
看上面的英文信息：
请为你的Gitlab instance 配置一个URL，通过设置external_url这一项在gitlab.rb 这个文件中。
然后再执行sudo gitlab-ctl reconfigure命令。
修改配置文件vim /etc/gitlab/gitlab.rc：
external_url 'http://192.168.17.118' # 修改为gitlab服务器的IP地址，对外服务。
初始化：gitlab-ctl reconfigure
时间比较久，需要3分钟左右的时间，会自动配置各个组件，并启动。
然后是查看状态：
gitlab-ctl status
从 /etc/gitlab/initial_root_password文件中得到密码，先登录，然后再更改下密码。
gitlab设置：
配置邮件服务的用途：
1）账号注册的时候，有邮件验证；
2）有合并请求的时候，邮件通知；
3）修改密码的时候，通过邮件修改；
Gitlab创建仓库：
第一步：在gitlab上创建项目（其实也就是存放代码的仓库）。
第二步：自定义项目名称等信息，现在比较新的版本已经没有描述信息了：
页面的信息跟github几乎是相同的。
设置SSH配置：
直接将之前生成的公钥信息拷贝过来。
这样开发者跟gitlab也做成了免密的了。
再看下项目名称：
[root@git-server ~]# git clone [email protected]:root/myproject.git

git clone将整个myproject项目克隆下来。
然后我们再执行代码上传。

是main分支，不是github上的master分支。
