问题
I'm following Github's instructions for adding an SSH key. I've generated the id_rsa.pub file from my AWS EC2 instance, but I cannot complete the step that has me copy the contents of the file using xclip because I cannot install xclip onto the EC2 instance.
- I tried to install xclip on the EC2 instance using
sudo yum install xclip, but that didn't work ("No package xclip available"). - So I looked around and found more detailed install instructions, but they didn't work either ("curl: (22) The requested URL returned error: 404 Not Found"), and the suggested correct URLs in the comments also failed.
- (I also tried just copying the text contents of the id_rsa.pub file using Putty and ctl-c, but Github declared the resulting key invalid.)
So, how do I install xclip on 64-bit Amazon Linux AMI 2012.09?
回答1:
I needed this today for a file larger than a ssh-key, and cat was not enough. You need to enable the EPEL repo in EC2 in order to get xclip:
wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
sudo rpm -ivh epel-release-latest-7.noarch.rpm
sudo yum-config-manager --enable epel
sudo yum install xclip -y
回答2:
You don't need xclip. Just ssh into the EC2 instance and cat the key to your terminal, then copy and paste it from your terminal to wherever you need it.

I don't mean to wake up the zombies but in case someone is still wondering you can wget the rpm (i.e. from here) and then
sudo yum localinstall xclip-0.12-1.el6.x86_64.rpm
Note: you may need to do the same for some dependencies.
