1. 环境说明

使用git + gitee

2. 安装配置

ubuntu@VM-8-3-ubuntu:~/wuxiang/git$ git --version
git version 2.25.1
ubuntu@VM-8-3-ubuntu:~/wuxiang/git$

2.1 配置user信息

ubuntu@VM-8-3-ubuntu:~/wuxiang/git$ git config --global user.name 'wuxxxxx'
ubuntu@VM-8-3-ubuntu:~/wuxiang/git$ git config --global user.email 156xxxx5802@163.com

2.2 config的三个作用域

local只对仓库有效
global对登录用户的所有仓库有效
system对系统的所有⽤用户有效

git config --local
git config --global
git config --system

显示config的作用域，加list

git config --list --local
git config --list --global
git config --list --system

ubuntu@VM-8-3-ubuntu:~/wuxiang/git$ git config --list
user.name=wuxxxxx
user.email=156xxxx5802@163.com

git_42">3. 建git仓库

git_43">3.1 把已有的项目代码纳入git管理

cd 项⽬目代码所在的⽂文件夹
git init

ubuntu@VM-8-3-ubuntu:~/wuxiang/git$ ll
total 8
drwxrwxr-x 2 ubuntu ubuntu 4096 Aug 10 20:13 ./
drwxrwxr-x 5 ubuntu ubuntu 4096 Aug 10 20:13 ../
ubuntu@VM-8-3-ubuntu:~/wuxiang/git$ git init
Initialized empty Git repository in /home/ubuntu/wuxiang/git/.git/
ubuntu@VM-8-3-ubuntu:~/wuxiang/git$ ll
total 12
drwxrwxr-x 3 ubuntu ubuntu 4096 Aug 10 20:22 ./
drwxrwxr-x 5 ubuntu ubuntu 4096 Aug 10 20:13 ../
drwxrwxr-x 7 ubuntu ubuntu 4096 Aug 10 20:22 .git/
ubuntu@VM-8-3-ubuntu:~/wuxiang/git$

git_65">3.2 新建的项目直接用git管理

cd 某个文件夹
git init your_project #会在当前路路径下创建和项目名称同名的文件夹
cd your_project

ubuntu@VM-8-3-ubuntu:~/wuxiang/git2$ ll
total 8
drwxrwxr-x 2 ubuntu ubuntu 4096 Aug 10 20:24 ./
drwxrwxr-x 6 ubuntu ubuntu 4096 Aug 10 20:24 ../
ubuntu@VM-8-3-ubuntu:~/wuxiang/git2$ git init empty_git_project
Initialized empty Git repository in /home/ubuntu/wuxiang/git2/empty_git_project/.git/
ubuntu@VM-8-3-ubuntu:~/wuxiang/git2$ ll empty_git_project/
total 12
drwxrwxr-x 3 ubuntu ubuntu 4096 Aug 10 20:24 ./
drwxrwxr-x 3 ubuntu ubuntu 4096 Aug 10 20:24 ../
drwxrwxr-x 7 ubuntu ubuntu 4096 Aug 10 20:24 .git/
ubuntu@VM-8-3-ubuntu:~/wuxiang/git2$

3.3 配置local的user和email

ubuntu@VM-8-3-ubuntu:~/wuxiang/git_learn$ ll
total 12
drwxrwxr-x 3 ubuntu ubuntu 4096 Aug 10 20:22 ./
drwxrwxr-x 5 ubuntu ubuntu 4096 Aug 10 20:26 ../
drwxrwxr-x 7 ubuntu ubuntu 4096 Aug 10 20:28 .git/
ubuntu@VM-8-3-ubuntu:~/wuxiang/git_learn$ git config --local user.name 'uuuuu'
ubuntu@VM-8-3-ubuntu:~/wuxiang/git_learn$ git config --local user.email '156xxxx5802@163.com'
ubuntu@VM-8-3-ubuntu:~/wuxiang/git_learn$ git config --local --list
core.repositoryformatversion=0
core.filemode=true
core.bare=false
core.logallrefupdates=true
user.name=uuuuu
user.email=156xxxx5802@163.com
ubuntu@VM-8-3-ubuntu:~/wuxiang/git_learn$ git config --list
user.name=wuxiang
user.email=156xxxx5802@163.com
pack.windowmemory=32m
core.repositoryformatversion=0
core.filemode=true
core.bare=false
core.logallrefupdates=true
user.name=uuuuu
user.email=156xxxx5802@163.com
ubuntu@VM-8-3-ubuntu:~/wuxiang/git_learn$

3.4 优先级：local > global > system

4. 远程仓库配置

在这里插入图片描述

ubuntu@VM-8-3-ubuntu:~$ ssh-keygen -t rsa -C "156xxxx5802@163.com"
（跳出的选项一直回车确认就好）
ubuntu@VM-8-3-ubuntu:~$ cd .ssh/
ubuntu@VM-8-3-ubuntu:~/.ssh$ ls
authorized_keys  id_rsa  id_rsa.pub  known_hosts
ubuntu@VM-8-3-ubuntu:~/.ssh$

拷贝id_rsa.pub文件中的所有内容，复制到如下位置（可以通过主页右上角「个人设置」->「安全设置」->「SSH 公钥」-> … ，添加生成的 public key（id_rsa.pub）到当前账户中。）
在这里插入图片描述

使用ssh -T 测试，通过的话输出如下内容：

ubuntu@VM-8-3-ubuntu:~/.ssh$ ssh -T git@gitee.com
Hi wuxiang(@wuxiang16)! You've successfully authenticated, but GITEE.COM does not provide shell access.
ubuntu@VM-8-3-ubuntu:~/.ssh$

关联远程仓库：
在这里插入图片描述

ubuntu@VM-8-3-ubuntu:~/wuxiang/git_learn$ git remote add origin git@gitee.com:wuxiang16/git_learn.git
ubuntu@VM-8-3-ubuntu:~/wuxiang/git_learn$ git remote -v
origin  git@gitee.com:wuxiang16/git_learn.git (fetch)
origin  git@gitee.com:wuxiang16/git_learn.git (push)
ubuntu@VM-8-3-ubuntu:~/wuxiang/git_learn$

由于远程仓库在创建时包含了LICENSE文件，本地仓库包含了Readme文件，两个仓库内容不同步，可以通过如下命令先同步：

ubuntu@VM-8-3-ubuntu:~/wuxiang/git_learn$ git pull origin master --allow-unrelated-histories
From gitee.com:wuxiang16/git_learn
 * branch            master     -> FETCH_HEAD

ubuntu@VM-8-3-ubuntu:~/wuxiang/git_learn$

5. 往仓库里添加文件并同步到远程仓库

创建几个测试文件，并同步到远程仓库：

ubuntu@VM-8-3-ubuntu:~/wuxiang/git_learn$ ll
total 52
drwxrwxr-x 3 ubuntu ubuntu  4096 Aug 11 11:03 ./
drwxrwxr-x 5 ubuntu ubuntu  4096 Aug 10 20:26 ../

-rw-rw-r-- 1 ubuntu ubuntu   350 Aug 11 11:03 .gitignore
-rw-rw-r-- 1 ubuntu ubuntu 35147 Aug 11 11:03 LICENSE
-rw-rw-r-- 1 ubuntu ubuntu     0 Aug 10 20:30 Readme
