I had to enter password every time I push my commits to git server. I can avoid doing it again and again by using SSH key:
1. In my computer, generate SSH Key:
$ cd ~/.ssh
$ ssh-keygen -t rsa -C "email@example.com"
The above command will create 2 files, id_rsa and id_rsa.pub. id_rsa.pub is your public key. Send it to the git server.
2. Copy the public key to the remote server:
$ ssh-copy-id -i ~/.ssh/id_rsa.pub myusername@remotehost
The command will prompt me to enter password of my user account in the remotehost. Enter and done.
+ After that, if I can ssh to the remote server without error, I can assume that it works:
trinh@mylocalpc$ ssh myusername@remotehost
+ If I get the error "Agent admitted failure to sign using the key", run the following command and try to ssh again:
From now on, whenever I push code to remote git server, I don't have to input my password anymore.
