2. GitLab代码仓库

2.1 GitLab安装

（官方推荐至少4G内存）

GitLab 官网

1. 安装依赖性（注意这是企业7的版本）

[root@server51 demo]# yum install -y curl policycoreutils-python openssh-server

2. 安装gitlab

[root@server51 ~]# rpm -ivh gitlab-ce-13.2.2-ce.0.el7.x86_64.rpm
warning: gitlab-ce-13.2.2-ce.0.el7.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID f27eab47: NOKEY

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

3. 修改配置文件/etc/gitlab/gitlab.rb中默认的clone链接。
   更改之后，不会立即生效，需要重载服务

[root@server51 ~]# cd /etc/gitlab/
[root@server51 gitlab]# vim gitlab.rb 
external_url 'http://172.25.21.51'

[root@server51 gitlab]# gitlab-ctl reconfigure

4. 查看当前gitlab各组件的状态

常用命令	说明
gitlab-ctl start	启动所有 gitlab 组件
gitlab-ctl stop	停止所有 gitlab 组件
gitlab-ctl restart	重启所有 gitlab 组件
gitlab-ctl status	查看服务状态
gitlab-ctl reconfigure	重载服务
gitlab-ctl tail	查看日志

[root@server51 gitlab]# gitlab-ctl status
run: alertmanager: (pid 5370) 27s; run: log: (pid 5150) 92s
run: gitaly: (pid 5300) 29s; run: log: (pid 4561) 224s

5. web测试

• root用户第一次登陆GitLab需要强制更改密码（密码至少8个字符）

2.2 GitLab使用

1. 根据个人情况，修改偏好配置

• 选择用户admin里的设置
• 选择左下方的偏好设置
• 选择中文社区

2. 新建项目

• 先添加密钥，允许gitlab服务免密访问本地

[root@server51 gitlab]# cd
[root@server51 ~]# ssh-keygen 
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:11ywMo4P1+jC6eCEUsfWEuOiuXFJmuJm5a8uIxjZcVI root@server51
The key's randomart image is:
+---[RSA 2048]----+

[root@server51 ~]# cd .ssh/
[root@server51 .ssh]# cat id_rsa.pub

• 新建项目，同步代码库到gitlab

3. 项目测试

• 删除本地demo，之后在git克隆

[root@server51 ~]# rm -fr demo/

• 克隆远端仓库的代码到本地（注意，记得修改本地解析文件，否则，克隆会很慢）

[root@server51 ~]# vim /etc/hosts

[root@server51 ~]# git clone git@172.25.21.51:root/demo.git
Cloning into 'demo'...
remote: Enumerating objects: 3, done.
remote: Counting objects: 100% (3/3), done.
remote: Total 3 (delta 0), reused 0 (delta 0), pack-reused 0
Receiving objects: 100% (3/3), done.
[root@server51 ~]# cd demo/
[root@server51 demo]# ls
README.md

• 远程信息被记录

[root@server51 demo]# git remote -v
origin	git@172.25.21.51:root/demo.git (fetch)
origin	git@172.25.21.51:root/demo.git (push)

3. 本地数据如何向远端同步？

• 建立一个测试文件

[root@server51 demo]# touch index.html
[root@server51 demo]# echo www.westos.org > index.html

• 添加测试文件到暂存区，提交测试文件到代码库

[root@server51 demo]# git status -s
?? index.html
[root@server51 demo]# git add index.html
[root@server51 demo]# git commit -m "add index.html"
[master d20f0e0] add index.html
 1 file changed, 1 insertion(+)
 create mode 100644 index.html
[root@server51 demo]# git status
# On branch master
# Your branch is ahead of 'origin/master' by 1 commit.
#   (use "git push" to publish your local commits)
#
nothing to commit, working directory clean
[root@server51 demo]# git status -s

• 上传push测试文件到gitlab

[root@server51 demo]# git push -u origin master
Counting objects: 4, done.
Delta compression using up to 2 threads.
Compressing objects: 100% (2/2), done.
Writing objects: 100% (3/3), 283 bytes | 0 bytes/s, done.

• web界面检验结果

在web界面可以远端图形化编辑，同步到本地
