How to change the ssh key while doing a "git pull" on a server with multiple users?-CodePudding

I am using an ec2 server in which there are two users. Let's call them user1 and user2 with their separate user1key and user2key in the ~/.ssh folder.

My git config file in the ~/.ssh folder looks like this

Host user1
    HostName github.com
    IdentityFile ~/.ssh/user1key
Host user2
    HostName github.com
    IdentityFile ~/.ssh/user2key

I want to use user1 to pull and commit changes to the origin. However, when I run git pull, it asks for the passphrase of user2key which I don't have.

I tried using git config user.name "user1" inside the repository and then did a git pull but it again asked for a passphrase for user2key.

I even tried removing the information for user2 from the config file and run git pull again but it still asked for the passphrase for user2key.

CodePudding user response：

user.name has nothing to do with authentication to the remote server.

If you are using a ~/.ssh/config with a Host entry named user1, then your remote URL must become:

git@user1:user1/repo-name

And you can test the connection to github.com with ssh -Tv user1.

Again, the name of the Host entry is what you need to use for your URL.
It becomes a shortcut for

ssh -i ~/.ssh/user1key -Tv [email protected]

Note: add User git in each Host subsection, that way you do not even have to specify git@.

Host user1
    HostName github.com
    User git
    IdentityFile ~/.ssh/user1key
Host user2
    HostName github.com
    User git
    IdentityFile ~/.ssh/user2key
