Many ssh keys for different git servers

   chmod 400 id_rsa_id1*
   

2. Generate ssh keypair 1

   cd ~/.ssh/
   ssh-keygen -t rsa -f id_rsa_id1
   chmod 400 id_rsa_id1*
   

3. Create ~/.ssh/config file

   #1 server
   Host github.com
           HostName github.com
           User user1
           IdentityFile ~/.ssh/id_rsa_id1
           IdentitiesOnly yes
   
   #2 server  
   Host gitlab.com
           HostName gitlab.com
           User user2
           IdentityFile ~/.ssh/id_rsa_id2
