Intro
The steps below are after you have done the initial setup. Assuming you did a minimal installation, didn't create a user and didn't configure the network-interface and hostname during the setup-wizard.
Creating a user with admin-rights (sudo)
- adduser <username> --> create a new user
- passwd <username> --> set a password for the user
- visudo --> to give the new user sudo-rights
add <user> ALL=(ALL) ALL after root ALL=(ALL) ALL
Now you can log off and logon and continue as the new non-root user.
Setting a hostname and configure the network interface
- nmtui --> configure network interface (make sure to set at least IP-address, gateway, DNS)
- systemctl restart network --> restart the network with the new configuration
- hostnamectl set-hostname <hostname> --> set hostname, make sure it's a FDQN
- hostnamectl status --> check the hostname configuration
Update the system with latest security and software patches
- yum update --> check for new version and updates the system when you accept the installation
- reboot --> restart the system after installation
Securing SSH access
