2) Install the libvirt and dependency packages:

yum -y install libvirt qemu-kvm virt-install virt-top libguestfs-tools bridge-utils

3) Start the libvirtd service:

[root@thiru ~]# systemctl status libvirtd

● libvirtd.service - Virtualization daemon

   Loaded: loaded (/usr/lib/systemd/system/libvirtd.service; enabled; vendor preset: enabled)

4) Enable the service for automatic load after reboot of the host:

[root@thiru ~]# systemctl enable libvirtd

[root@thiru ~]#

=========================================================================

5) Crate a kubernets user who is going to manage the service

[root@thiru ~]# useradd tperiyas

[root@thiru ~]# passwd tperiyas

=========================================================================

6) Assign the user into libvirt group

[root@thiru ~]# usermod -a -G libvirt tperiyas

[root@thiru ~]#

=========================================================================

7) Enable the below parameter in /etc/libvirt/libvirtd.conf and restrict the permission for other users.

# This is restricted to 'root' by default.

unix_sock_group = "libvirt"

# Set the UNIX socket permissions for the R/O socket. This is used

# for monitoring VM status only

#

# Default allows any user. If setting group ownership, you may want to

# restrict this too.

unix_sock_ro_perms = "0777"

========================================================================

8) Download a minikube binary folder:

wget https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64

========================================================================

9) changed the folder permission for exectable to all and moved under /usr/local/bin directory:

root@thiru ~]# chmod +x minikube-linux-amd64

[root@thiru ~]#

[root@thiru bin]# mv  minikube-linux-amd64 minikube

[root@thiru bin]#

=========================================================================

10) Your minikube machine is ready.

[root@thiru bin]# minikube version

minikube version: v1.33.1
