Centos 6 is not using the latest kernel installed.

Posted on February 5, 2018

I have a server that has the following kernels installed:

kernel-2.6.32-696.13.2.el6.x86_64
kernel-2.6.32-696.16.1.el6.x86_64
kernel-2.6.32-696.18.7.el6.x86_64
kernel-2.6.32-696.20.1.el6.x86_64

I’m using the DO GrubLoader 0.2 kernel in the control panel, but the server boots with:

2.6.32-696.18.7.el6.x86_64

I’ve changed /etc/grub.conf so it specifies the 20.1 kernel:

#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.32-696.20.1.el6.x86_64)
        root (hd0,0)
        kernel /boot/vmlinuz-2.6.32-696.20.1.el6.x86_64 ro root=UUID=59e3d92c-67e1-4cc4-bc90-76123b617391 rd_NO_LUKS rd_NO_LVM LANG=en_US.UTF-8 rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto  KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM rhgb quiet
        initrd /boot/initramfs-2.6.32-696.20.1.el6.x86_64.img

What I am I missing? Why won’t it boot to 2.6.32-696.20.1 or 2.6.32-696.16.1?
