bookmark_borderEnabling BBR on Ubuntu 23.04


In this week’s feature highlight, we look at How to Enable BBR on Ubuntu 23.04

BBR stands for Bottleneck Bandwidth and RTT is a congestion control system. You can enable TCP BBR on your Linux desktop to improve the overall web surfing experience. By default, Linux uses the Reno and CUBIC congestion control algorithm.

Enabling BBR in Linux can help improve network performance by optimizing bandwidth utilization, reducing latency, and mitigating packet loss. We’ll show you how this is enabled:

Run the following command to check available congestion control algorithms,

sysctl net.ipv4.tcp_available_congestion_control


root@ubuntu:~# sysctl net.ipv4.tcp_available_congestion_control
net.ipv4.tcp_available_congestion_control = reno cubic

Run the below command to check the current congestion control algorithm used in your system,

sysctl net.ipv4.tcp_congestion_control


root@ubuntu:~# sysctl net.ipv4.tcp_congestion_control
net.ipv4.tcp_congestion_control = cubic

Enabling TCP BBR in Ubuntu

Open the following configuration file /etc/sysctl.conf to enable enable TCP BBR.

nano /etc/sysctl.conf

At the end of the config file, add the following lines.


Save the file, and refresh your configuration by using this command,

sysctl -p


root@ubuntu:~# sysctl -p
net.core.default_qdisc = fq
net.ipv4.tcp_congestion_control = bbr

Now, Verify if BBR is enabled in your system,

sysctl net.ipv4.tcp_congestion_control


root@ubuntu:~# sysctl net.ipv4.tcp_congestion_control
net.ipv4.tcp_congestion_control = bbr

bookmark_borderInstalling WordPress with LEMP Stack on Ubuntu 23.04


In this week’s feature highlight, we look at How to Install WordPress with LEMP Stack on Ubuntu 23.04

WordPress is one of the most popular website-building tools available out there. It is a simple way to get your online presence and perfect for those who do not know how to code and want a simple and effective way to share and build your story on the internet.


Creating Database

Log into MySQL with the following command.

mysql -u root -p

First, we’ll create a new database.

CREATE DATABASE wordpress_db;

Next, create a new MySQL user account that we will use to operate on WordPress’s new database, with the username “wordpress_user”.

CREATE USER 'wordpress_user'@'localhost' IDENTIFIED BY 'password';

Note: Replace “password” with a safe and secure password when creating the wordpress_user

Link the user and DB together by granting our user access to the database.

GRANT ALL PRIVILEGES ON wordpress_db.* to wordpress_user@'localhost';

Flush the privileges so that MySQL knows about the user permissions we just added.


Exit out of the MySQL command prompt by typing.



root@crown:~# mysql
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 81
Server version: 10.6.7-MariaDB-2ubuntu1 Ubuntu 23.04

Query OK, 0 rows affected (0.003 sec)

MariaDB [(none)]> exit

Download and Install WordPress

Download the latest WordPress,

wget -O /tmp/wordpress.tar.gz

Unzip the downloaded WordPress file.

tar -xzvf /tmp/wordpress.tar.gz -C /var/www/html

Change the permission of the site directory.

chown -R www-data:www-data /var/www/html/wordpress

Create a Server Block or vHost

We will create a server block (also called vHost) for the WordPress site and have it’s own configuration.

Create a new configuration file using your favourite editor,

vi /etc/nginx/sites-available/

Replace with actual domain name.

And insert the following content into the file.

server {
  listen 80;
  listen [::]:80;
  #server_name _;
  root /var/www/html/wordpress/;
  index index.php index.html index.htm index.nginx-debian.html;

  error_log /var/log/nginx/wp.domainhere.info_error.log;
  access_log /var/log/nginx/wp.domainhere.info_access.log;

  location / {
    try_files $uri $uri/ /index.php;

  location ~ \.php$ {
    fastcgi_pass unix:/run/php/php8.1-fpm.sock;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
    include snippets/fastcgi-php.conf;

 # A long browser cache lifetime can speed up repeat visits to your page
  location ~* \.(jpg|jpeg|gif|png|webp|svg|woff|woff2|ttf|css|js|ico|xml)$ {
       access_log        off;
       log_not_found     off;
       expires           360d;

  # disable access to hidden files
  location ~ /\.ht {
      access_log off;
      log_not_found off;
      deny all;

Save and exit the file.

Next create a symbolic link of the configuration in the sites-enabled directory with the following command:

ln -s /etc/nginx/sites-available/ /etc/nginx/sites-enabled/

Remove default Nginx server blocks to prevent Nginx automatic requests routing.

rm /etc/nginx/sites-available/default

Set up SSL Certificate

Run the command to install certbot specific to Nginx

snap install --classic certbot

Run this command to get a certificate and have Certbot edit your Nginx configuration automatically to serve it, turning on HTTPS access in a single step.

certbot --nginx -d -d

You will have to accept the terms of service.

 - Congratulations! Your certificate and chain have been saved at:
   Your key file has been saved at:
   Your cert will expire on 2020-09-05. To obtain a new or tweaked
   version of this certificate in the future, simply run certbot again
   with the "certonly" option. To non-interactively renew *all* of
   your certificates, run "certbot renew"
 - Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.
 - If you like Certbot, please consider supporting our work by:

   Donating to ISRG / Let's Encrypt:
   Donating to EFF:          

You will receive this acknowledgement that the SSL certificate for and are successfull.

You can now verify your website using https:// that the connection is secure with the lock icon in the usrl bar.

To check that you have top-of-the-line installation, navigate to

Confirm that the configuration is all OK and there are no errors.

nginx -t

you would see an output like below:

root@vps:~# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

Now that the configuration has no errors, restart the web server:

systemctl restart nginx

Navigate to your browser. OR http://IP_ADDRESS/wordpress

Note: Replace or IP_ADDRESS with the actual domain name or IP address of your website/server.


Start a WordPress installation by clicking on the Run the installation button.


Provide the requested information.


Once WordPress has been installed log in with your new user credentials.

bookmark_borderInstalling Docker On Ubuntu 23.04

In this week’s feature highlight, we look at How to Install Docker On Ubuntu 23.04

What is docker?

Docker is basically a container engine which uses the Linux Kernel in order to create the containers on top of an operating system. Which is used to create, deploy and run the applications.

Install Docker

Install the docker using the apt package manager.

apt install

Start and enable docker

systemctl enable --now docker

Check Docker service status

systemctl status docker

Create a group called docker,

groupadd docker

To add an user into the docker user group

usermod -aG docker $USER

If you want to add a different user, replace $USER with existing username.

Check docker version,

docker --version


root@ubuntu:~# docker --version
Docker version 20.10.21, build 20.10.21-0ubuntu3

Test docker using the hello-world container.

docker run hello-world


root@ubuntu:~# docker run hello-world
Unable to find image 'hello-world:latest' locally

Status: Downloaded newer image for hello-world:latest

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash
