I am trying to make ssh key for a the deployer user
[deployer@server /]$ ssh-keygen -t rsa -b 4096 -C "email@yahoo.com" Generating public/private rsa key pair. Enter file in which to save the key (/home/deployer/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: open /home/deployer/.ssh/id_rsa failed: Permission denied. Saving the key failed: /home/deployer/.ssh/id_rsa.
i have tried all of theses
[root@server /]# chmod -R 644 /home/deployer [root@server /]# chmod -R 755 home/deployer [root@server /]# chmod -R 755 /home/deployer [root@server /]# chmod -R 755 home/deployer

Answer
It looks like you don’t have the privileges to save the files necessary to complete the operation. Try running the same command using sudo:
sudo ssh-keygen -t rsa -b 4096 -C "email@yahoo.com"
When prompted for a password, enter your password. If this doesn’t work, you can try using the command su, which will switch to the root user directly.
