1、安装git Centos7 查看git --version
2、配置用户名密码
git config --global user.name "xxx" git config --global user.email "[email protected]"
3、为GitHub账号添加SSH Keys
ssh-keygen -t rsa -C "[email protected]" 生成key
系统会提示key的保存位置（一般是~/.ssh目录）和指定口令，保持默认，连续三次回车即可
-
复制SSH Key到GITHUB
打开该文件，id_rsa.pub文件内的内容，粘帖到github帐号管理的添加SSH key界面中
cat ~/.ssh/id_rsa.pub登录github-> Settings-> SSH and GPG Keys-> New SSH key添加
- 测试是否连接成功
ssh -T git@github.com会提示
The authenticity of host 'github.com (192.30.255.112)' can't be established.
RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.
Are you sure you want to continue connecting (yes/no)? yes
直接输入 yes 就可以了，然后提示成功：
Warning: Permanently added 'github.com,192.30.255.112' (RSA) to the list of known hosts.
Hi smartwen! You've successfully authenticated, but GitHub does not provide shell access.
git推送到GitHub步骤：
git init
git add file
git commit -m "注释"
git remote add origin [email protected]:smartwen/selIDE
git push -u origin master
解决一个巨坑
我使用了命令：
git push -u origin master
结果报错如下：
error: failed to push some refs to '[email protected]:你的远程库名.git'
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
hint: 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
从提示可以看出，是由于两者不同步，因此需要先pull，进行合并然后在进行push，
因此先使用
git pull --rebase origin master
将远程文件同步下来。
然后再执行推送
git push -u origin master
终于，成功！
