    Does the above steps apply to CentOS 6.x as well ?

    • Hi Steven,

      No, above mentioned steps are not applicable for CentOS 6 or RHEL 6 servers.

      Please refer the following steps to boot CentOS 6 / RHEL 6 Server in Single User mode:

      1) Reboot the server, Go to Grub menu and select the kernel
      2) Press ‘e’ and go to the end of line which starts with Kernel and type ‘1’ or single.
      3) Then type ‘b’ to boot your server in single or maintenance mode.
      4) Now perform your troubleshooting steps like reset the password, scanning and disabling specific service etc.
      5) Reboot the server after doing troubleshooting.
