(Use centOS as example, other distributions are similar)

$ yum update
Release version should be higher than 7.5:
$ cat /etc/redhat-release

Install elrepo and update the core:
$ rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
$ rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm
$ yum --enablerepo=elrepo-kernel install kernel-ml -y

Check the installed core,
$ awk -F\' '$1=="menuentry " {print i++ " : " $2}' /etc/grub2.cfg
and set the elrepo one to default
$ grub2-set-default [elepro core index]

Copy the following to /etc/sysctl.conf,
net.core.default_qdisc = fq
net.ipv4.tcp_congestion_control = bbr

and load the file
$ sysctl -p

Test if bbr is turned on:
$ sysctl net.ipv4.tcp_congestion_control
This should give you
net.ipv4.tcp_congestion_control = bbr
Could also try
$ lsmod | grep bbr
