Basic configuration so let's begin.

Configure SSH Keys

Login to Ubuntu system

Start SSH-Agent

eval "$(ssh-agent)"

Generate a new key, do not enter a passphrase

cd .ssh
ssh-keygen -t rsa -b 4096 -C “github_email_address” -f id_github
passphrase: <none>

This generates two files

• private: id_github
• public: id_github.pub

Set permissions

chmod 600 id_github*

Add to keychain

ssh-add -k ~/.ssh/id_github

Verify

ssh-add -l

Add public key to Github account

Copy content of id_github.pub

Login to Github account

• Settings
• SSH and GPG keys
• New SSH key
• Title: use a descriptive term
• Paste to SSH key
• Save

Test SSH Keys

Clone a public and a private repository from your Github account.

For example

git clone git@github.com:<your-github-id>/<your-repo>

Other

Notice this does not permanently add the ssh keys as I am only interested in pulling from Github for a redeployment. The deployment script has the following code

eval "$(ssh-agent)"
ssh-add -k ~/.ssh/id_github

which enables the git clone.

Copy over SSH using rsync

For example, copy from local to folder remote-folder at remote server mywebsite

cd
cd tmp
rsync -r --exclude=".git" --exclude=".gitignore" --exclude=".DS_Store" \
    music mywebsite:remote-folder

Copy over SSH using scp

For example, copy from local to folder remote-folder at remote server mywebsite

cd
cd tmp
scp -r tmp/. $REMOTE_USER@mywebsite:$REMOTE_HOME/remote-folder

For example, copy from remote-folder at remote server mywebsite to local

cd tmp
scp -r $REMOTE_USER@mywebsite:$REMOTE_HOME/bin .
