As mentioned earlier that the Linode VMs come with a custom kernel and they are not compatiable with Gluu Server. The following steps will help to update your kernel so that Gluu Server can be installed.
It is a recommended to check for the current version. Run the following command to check for kernel version:
# uname -a
If the output contains the
-Linode then it is a custom kernel and it is mandate to run the following command:
# apt-get install linux-image-virtual grub2
After the installation of the new kernel and grub2, grub2 has to be configured.
Edit the file
grub under the
# vim /etc/default/grub
Please ensure that the following lines are present in the
GRUB_TIMEOUT=10 GRUB_CMDLINE_LINUX="console=ttyS0,19200n8" GRUB_DISABLE_LINUX_UUID=true GRUB_SERIAL_COMMAND="serial --speed=19200 --unit=0 --word=8 --parity=no --stop=1"
Run the following command to update grub and reboot VM.
