Git安装部署[二]

Gitlab

Git介绍
  开源免费的分布式版本控制系统(DVCS)
Git的主要特点
  支持离线工作，多点同步
  速度快
  使用40位哈希值标示版本号
  本地库、缓冲区、中心库三层结构
　　本地库：中心库的完整镜像(.git目录)
　　缓存区：用于存放和整理待提交改动的空间,支持选择性提交(.git/index)
　　中心库：代码托管服务器管理下的git库
  轻量级的分支和标签

working directory
　　-->git add
staging area
　　-->git commit
repository

working directory---staging area--->repository (git commit -a)

commit-id
　　40位的哈希值,全球唯一的标示一次提交的完整镜像,相当于一个快照
HEAD
　　指代当前checkout状态的commit,后续commit都基于它完成,类似链表
refs
　　分支管理的命名空间,

修改gitlab url的步骤
1. 编辑 /root/data/gitlab/config/gitlab.rb
2. 修改 external_url 'http://106.2.3.227' 这个配置默认是注释掉的
3. 进入gitlab容器 docker exec -it devops_gitlab_1 bash
4. 重新加载配置 gitlab-ctl reconfigure
5. 重启gitlab gitlab-ctl restart

http的方式

[root@linux-node2 ~]# cd /root/devops/
[root@linux-node2 devops]# mkdir -pv workspace
mkdir: created directory ‘workspace’
[root@linux-node2 devops]# cd workspace
[root@linux-node2 workspace]# git clone http://192.168.56.12/devops/account.git
Cloning into 'account'...
Username for 'http://192.168.56.12': root
Password for 'http://root@192.168.56.12': 

ssh的方式

ssh-keygen -t rsa -C root@devops.com
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):    一直回车
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:
05:97:6a:f6:3a:6c:ce:f9:2b:9f:88:22:23:74:38:8d root@devops.com
The key's randomart image is:
+--[ RSA 2048]----+
|        . ..     |
