.. _elrepo_kernel_inst:
Install kernel from elrepo
==========================
At first need enable ELRepo Repository. To set up ELRepo repository, you need to import its official GPG key and then install ELRepo RPM as follows. Also you can follow original http://elrepo.org/tiki/tiki-index.php instalation guide.
For Centos 7
.. code-block:: sh
rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
rpm -Uvh https://www.elrepo.org/elrepo-release-7.0-3.el7.elrepo.noarch.rpm
For Centos 8
.. code-block:: sh
rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
yum install https://www.elrepo.org/elrepo-release-8.0-2.el8.elrepo.noarch.rpm
Install kernel-ml and kernel-ml-devel
.. code-block:: sh
yum --enablerepo=elrepo-kernel install -y kernel-ml kernel-ml-devel
To show installed kernels run command:
.. code-block:: sh
awk -F\' '$1=="menuentry " {print $2}' /etc/grub2.cfg
Set installed kernel as default for grub2 bootloader:
.. code-block:: sh
grub2-set-default 0
Reboot system and check kernel version
.. code-block:: sh
uname -r
Now you can continue :ref:`install_centos` with modules **vlan_mon** and **ipoe**
