linux下git命令基本用法，Linux，Centos7下搭建简单的git服务器

下载git并初始化

10.211.55.3 作为服务端git server

yum install -y git

这个主机安装git命令

# useradd git# passwd git# su gitcentos7 git@parallels:~$ pwd/home/gitcentos7 git@parallels:~$ mkdir -p repos/app.git && cd ./repos/app.git

总库初始化、总库一般都是空库

centos7 git@parallels:~/repos/app.git$ git --bare initInitialized empty Git repository in /home/git/repos/app.git/

然后用我的macOS作为客户端：

首先实现免密钥到服务器：

ssh公钥实现免交互，将我Mac的key放到git服务器10.211.55.3上在10.211.55.3上操作如下：centos7 git@parallels:~/repos$ mkdir /home/git/.ssh && chmod 700 /home/git/.sshcentos7 git@parallels:~/repos$ cd /home/git/.ssh/centos7 git@parallels:~/.ssh$ vi authorized_keyscentos7 git@parallels:~/.ssh$ chmod 600 authorized_keys

放到对应的authorized_keys里面去

第三部从客户端开始测试，当然客户端也是有git命令的

测试能否正常使用git，本地先创建文件准备提交git服务器

➜ git pwd/Users/lex/Downloads/git➜ git mkdir test-git➜ test-git git clone git@10.211.55.3:/home/git/repos/app.git➜ test-git git clone git@10.211.55.3:/home/git/repos/app.gitCloning into 'app'... ___ ___ (o o) (o o)( V ) ALex CentOS ( V )--m-m-----------------m-m--remote: Counting objects: 3, done.remote: Total 3 (delta 0), reused 0 (delta 0)Receiving objects: 100% (3/3), done.➜ test-git cd app➜ app git:(master) lsindex.html➜ app git:(master) tree.└── index.html0 directories, 1 file➜ app git:(master) touch index2.html && echo 456 > index2.html➜ app git:(master) ✗ git statusOn branch masterYour branch is up to date with 'origin/master'.Untracked files: (use "git add <file>..." to include in what will be committed) index2.htmlnothing added to commit but untracked files present (use "git add" to track)➜ app git:(master) ✗ git add index2.html强行插入2行,第一次commit代码的时候下面是需要设置的，否责推送会报错error: src refspec refs/heads/master does not match any详细参考文章结尾部分：➜ app git:(master) ✗ git config --global user.email "abc@outlook.com"➜ app git:(master) ✗ git config --global user.name "ALex"➜ app git:(master) ✗ git commit -m "secend commit"[master b726e76] secend commit 1 file changed, 1 insertion( ) create mode 100644 index2.html➜ app git:(master) git push ___ ___ (o o) (o o)( V ) ALex CentOS ( V )--m-m-----------------m-m--Enumerating objects: 4, done.Counting objects: 100% (4/4), done.Delta compression using up to 12 threadsCompressing objects: 100% (2/2), done.Writing objects: 100% (3/3), 270 bytes | 270.00 KiB/s, done.Total 3 (delta 0), reused 0 (delta 0), pack-reused 0To 10.211.55.3:/home/git/repos/app.git 36fc8b8..b726e76 master -> master

*** Please tell me who you are.

Run

git config --global user.email "you@example.com"

git config --global user.name "Your Name"

to set your account's default identity.

Omit --global to set the identity only in this repository.

fatal: unable to auto-detect email address (got 'lex@Mac.(none)')

上面这个错误是致命的，所以首先要执行上面这个命令

否责下面都过不去
