问题
I want to deploy rails app to digital ocean. I use this turorial: http://blog.flatironschool.com/using-digital-ocean-and-dokku-for-easier-rails-app-deploys/
When I do this:
First, you’ll need to copy your computer’s public SSH key. Go to your terminal and run this: $ cat /.ssh/idrsa.pub
I get the following output:
jonstark@jonstark-pc:~$ cat /.ssh/idrsa.pub
cat: /.ssh/idrsa.pub: No such file or directory
What are my next actions? (I am really newbie to ubuntu). I understand that may be I should ask this question in another place. So if it so feel to tell me where.
Okay. I did something after googling. Here what I did:
jonstark@jonstark-pc:~$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/jonstark/.ssh/id_rsa): ocean
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in ocean.
Your public key has been saved in ocean.pub.
The key fingerprint is:
b6:8e:de:5f:37:2f:b6:96:d2:53:16:89:ef:a8:1c:5a jonstark@jonstark-pc
The key's randomart image is:
+--[ RSA 2048]----+
| |
| |
| . .|
| . o |
| S . .|
| . . .o|
| . E..=+ |
| + +.ooB+ |
| .o oo.o.+.+.|
+-----------------+
Then I found this generated ocean.pub file and copy paste the ssh key to digital ocean
But I gues I did everything wrong and I should not store the key in ocean.pub but in /.ssh/idrsapub instead.
Okay also I did this:
jonstark@jonstark-pc:~$ ssh-copy-id dokku@45.55.21.53
/usr/bin/ssh-copy-id: ERROR: No identities found
I am still confused
What do I do now?
回答1:
To get your public key in ubuntu you can try cat ~/.ssh/id_rsa.pub
If that doesn`t work you probably have to setup your ssh keys. A good tutorial step by step can be found here
