我对编码完全不熟悉,正在开设一个关于课程的启动课程:https://class.coursera.org/startup-001/lecture/87

尝试连接到我在AWS上创建的EC2 Ubuntu实例时,我收到了拒绝权限(publickey)

1. 设置AWS Istance
2. 将安全性设置为默认值并添加端口22并启动

3. 课程告诉我然后输入:

   chmod 400 trevor-learning.pem ssh -i trevor-learning.pem\ec2-user@ec2-XX-XXX-XX-XX.us-west-2.compute.amazonaws.com

然后这给了我这个错误:权限被拒绝(publickey).

我已经看过其他问题并尝试将ubuntu @切换到ec2-user和其他一些东西,但我仍然无法连接.

我也试过:trevor-larsons-macbook-pro:下载trev $ chmod 600 trevor-learning.pem trevor-larsons-macbook-pro:下载trev $ ssh -v -i trevor-learning ubuntu @ ec2-XX-XXX-XX - XX.us-west-2.compute.amazonaws.com

这给了我:

OpenSSH_5.9p1, OpenSSL 0.9.8x 10 May 2012

我想在这里模仿Spotify的登陆页面:https://www.spotify.com/uk/video-splash/？ utm_source = sparkify&utm_medium = web&utm_campaign = start

我对编码很新,但之前创建了一些着陆页,但从来没有以HTML和视频为背景.

我想要与Spotify相同的布局,没有滚动功能或声音.然后,我想能够点击按钮,并有一个人可以填写并提交的表格.不太清楚如何去做.

TLDR:

• 如何做HTML5视频背景
• 像表单一样创建JS弹出窗口
• 从哪里获取视频/格式作为背景
