1.
$ git push origin master

	git@gitee.com: Permission denied (publickey).
	fatal: Could not read from remote repository.

	Please make sure you have the correct access rights and the repository exists.

解决方法：
	1.1生成新的秘钥
		$ ssh-keygen -t rsa -C "youremail@email.com"
		$ ssh-agent -s

	1.2查看公钥
		$ cat ~/.ssh/id_rsa.pub

		然后复制此公钥到gitee中保存。

	1.3验证连接
		$ ssh -T git@gitee.com
		
		Hi dagger! You've successfully authenticated, but GITEE.COM does not provide shell access.

2.$ git push

	To gitee.com:wdz_dagger/test.git
	 ! [rejected]        master -> master (non-fast-forward)
	error: failed to push some refs to 'gitee.com:wdz_dagger/test.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.

解决方法：
	2.1强制覆盖本地文件：
	git stash
		保护工作现场
	git pull --rebase origin master
		本地恢复文件
	git push -u origin master
		推送

	2.2
	或者强制上传覆盖远程文件，
	git push -f origin master
	(这个命令在团队开发的时候最好不要用,否则可能会有生命危险)

	2.3
	git rebase --abort
		回退版本
	git pull origin master --allow-unrelated-histories
		本地恢复文件
	git status
		查看master分支状态
	git add xxx
	git commit -m xxx
	git push
