What Do I Do If the Login Page Does Not Respond?

Symptom

On the page for remotely logging in to a BMS, after you press Enter, the page does not respond.

Possible Causes

The BMS OS configuration does not allow remote login to the BMS.

Solution

Use a key pair to log in to the BMS and configure the OS as required. The configuration varies depending on the OS. The following part provides configurations of some OSs as examples. For details, see "Configuring Remote Login to a BMS" in Bare Metal Server Private Image Creation Guide.

1. Modify the configuration file.
   • For SUSE Linux Enterprise Server 12 SP2, SUSE Linux Enterprise Server 12 SP1, Ubuntu 16.04 Server, CentOS Linux 7.3, and EulerOS 2.2, use the vi editor to open the /etc/default/grub file and add console=tty0 console=ttyS0 after GRUB_CMDLINE_LINUX.
     Figure 1 Example
     
   • For Oracle Linux 7.3 and Red Hat Enterprise Linux 7.3, use the vi editor to open the /etc/sysconfig/grub file and add console=tty0 console=ttyS0 after GRUB_CMDLINE_LINUX.

2. Update the configuration.
   • For SUSE Linux Enterprise Server 12 SP2, Oracle Linux 7.3, Red Hat Enterprise Linux 7.3, CentOS Linux 7.3, and EulerOS 2.2, run the following commands to update the configuration:

     stty -F /dev/ttyS0 speed 115200

     grub2-mkconfig -o /boot/grub2/grub.cfg

     systemctl enable serial-getty@ttyS0

   • For Ubuntu 16.04 Server, run the following commands to update the configuration:

     stty -F /dev/ttyS0 speed 115200

     grub-mkconfig -o /boot/grub/grub.cfg

     systemctl enable serial-getty@ttyS0

3. (Optional) Modify the security configuration file.

   If you log in to the BMS through the serial port as user root, you need to modify the security configuration file. Add the following information to the end of /etc/securetty:

4. Run the reboot command to restart the OS.

After configuring the BMS OS, check whether you can log in to the BMS remotely.
