To change the remote port on CentOS 7, you need to edit the SSH server configuration file and restart the SSH service. Here are some steps:<\/p>\n

    \n
  1. Login to the CentOS 7 server as the root user.<\/li>\n
  2. Open the SSH server configuration file \/etc\/ssh\/sshd_config, and you can edit it using a text editor like vi or nano.<\/li>\n
  3. Edit the sshd_config file with superuser privileges using the vi text editor.<\/li>\n
  4. Locate the “#Port 22” line in the configuration file and either comment it out or delete it.<\/li>\n
  5. Add a new port number below the line, for example, changing the port number to 2222:<\/li>\n
  6. Port number 2222<\/li>\n
  7. Save the file and exit the editor.<\/li>\n
  8. Restart the SSH service to apply the changes.<\/li>\n
  9. Restart the sshd service using systemctl command.<\/li>\n<\/ol>\n

    Now, you will be able to remotely log in to the CentOS 7 server using the modified port number through SSH. Make sure to open the new port in the firewall so that the SSH service can be accessed. If you are using a firewall management tool like firewalld, you can use the following command to open the new port:<\/p>\n

    sudo firewall-cmd --permanent --zone=public --add-port=2222\/tcp\r\nsudo firewall-cmd --reload\r\n<\/code><\/pre>\n
    Please be aware that if your server is located in a restricted network environment, you may also need to configure port forwarding on network devices (such as routers or firewalls) to route external traffic to the modified port.<\/p>\n","protected":false},"excerpt":{"rendered":"
