CentOS 7 SSH Login Setup Guide
Remote login in CentOS7 is typically done through an SSH (Secure Shell) connection. The following are the steps to remote login in CentOS7:
- Open the terminal and type the following command to install the OpenSSH server:
sudo yum install openssh-server
- Start the SSH service and set it to automatically start on boot.
sudo systemctl start sshd
sudo systemctl enable sshd
- Check the status of the SSH service to ensure it is running.
sudo systemctl status sshd
- Make sure the firewall allows SSH traffic to pass through. You can use the following command to open the port for SSH service (default port is 22):
sudo firewall-cmd --zone=public --add-port=22/tcp --permanent
sudo firewall-cmd --reload
- Open the terminal on the remote computer and enter the following command to connect to the CentOS7 server:
ssh username@server_ip_address
The username is the name used on the CentOS7 server, while the server_ip_address is the IP address of the CentOS7 server.
- Please enter the password to complete the remote login.
By following these steps, you will be able to remotely log in to your CentOS 7 server. Make sure you have authorized the relevant users for remote login and take necessary measures to ensure network security.
