git push -u origin master 出错 \Permission denied (publickey). fatal: Could not read from remote repo

在本地写好项目，一路git add * 和 git commit -m 'XXX'

然后在github上新建仓库，准备关联后，把代码推送至远程仓库

在git push 时就出错了：

(venv) [willie@localhost DJangoHotel_Python]$ git remote add origin [email protected]:williezh/hotelbooksystem.git
(venv) [willie@localhost DJangoHotel_Python]$ git remote -v

origin [email protected]:williezh/hotelbooksystem.git (fetch)

origin [email protected]:williezh/hotelbooksystem.git (push)

(venv) [willie@localhost DJangoHotel_Python]$ git push -u origin master

\Permission denied (publickey).
fatal: Could not read from remote repository.


Please make sure you have the correct access rights

and the repository exists.

查看了好多博客，并试验后，发现是密钥配置的问题：

解决了Permission的问题后，又出现了hint的问题

(venv) [willie@localhost DJangoHotel_Python]$ git push -u origin master

To github.com:williezh/hotelbooksystem.git
 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to '[email protected]:williezh/hotelbooksystem.git'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

(venv) [willie@localhost DJangoHotel_Python]$ git push -u origin master

可以上传了，但是因为包含了虚拟环境的文件夹venv，导致文件太大，上传很慢

果断ctrl+c打断上传，然后：

(venv) [willie@localhost DJangoHotel_Python]$ deactivate
 [willie@localhost DJangoHotel_Python]$ cd ..
[willie@localhost projects]$ git clone https://github.com/williezh/hotelbooksystem
[willie@localhost projects]$ cd hotelbooksystem/

把DJangoHotel_Python文件夹里，除venv外的所有可见文件及文件夹，复制到当前目录（手动操作）

[willie@localhost hotelbooksystem]$ git add *
[willie@localhost hotelbooksystem]$ git commit -m 'version 1.0'
[willie@localhost hotelbooksystem]$ git push -u origin master

输入用户名和密码，成功上传！

总结：本地仓库，在git init之后，就应该编辑.git/info/exclude文件，忽略掉虚拟环境和～文件，以免git push的时候文件太大。
