This post shows students and new users steps to install Ghost CMS on Ubuntu Linux with Nginx support. Ghost is a powerful open source publishing platform for the modern web built on Node.js platform.

The new Ghost 2.0 introduces many new features including, a powerful new editor, multi-language support, custom homepages, dynamic routes, custom structures and much more.

Ghost is a clean and lightweight platform designed for bloggers who want to focus on blogging and nothing else. Unlike WordPress and other content management systems which are based on PHP, Ghost is simple in design and function.

No additional packages and server needed, just JavaScript.

In this post, we’re going to show you how to install Nginx as proxy, MariaDB, and use Let’s Encrypt SSL certificate to secure Ghost website.

For more about Ghost, please visit its homepage.

To get started with installing Ghost on Ubuntu Linux, follow the steps below:

How to install Nginx on Ubuntu Linux

This this post, we’re going to be install Nginx HTTP server to serve as proxy to Ghost. Nginx is lightweight and should be perfect to run with Ghost.

To install Nginx, run the commands below:

sudo apt update
sudo apt install nginx

After installing Nginx, the commands below can be used to stop, start and enable Nginx service to always start up with the server boots.

sudo systemctl stop nginx.service
sudo systemctl start nginx.service
sudo systemctl enable nginx.service

Once Nginx is installed, open a web browser and browse to the server hostname or IP address. If you see a Nginx welcome page, Nginx is successfully installed and running on Ubuntu.

http://localhost
nginx default home page test

How to install MariaDB on Ubuntu Linux

We’re going to be using a database server with Ghost. If you’re looking for a truly open source database server, then MariaDB is a great place to start.

To install MariaDB run the commands below:

sudo apt install mariadb-server

After installing MariaDB, the commands below can be used to stop, start and enable MariaDB service to always start up when the server boots.

sudo systemctl stop mariadb.service
sudo systemctl start mariadb.service
sudo systemctl enable mariadb.service

After that, run the commands below to secure MariaDB server by creating a root password, disallowing remote root access removing anonymous and more.

sudo mysql_secure_installation

When prompted, answer the questions below by following the guide.

If you've just installed MariaDB, and haven't set the root password yet, you should just press enter here.

Enter current password for root (enter for none): PRESS ENTER

Switch to unix_socket authentication [Y/n] n

Change the root password? [Y/n] n

Remove anonymous users? [Y/n] y

Disallow root login remotely? [Y/n] y

Remove test database and access to it? [Y/n] y

Reload privilege tables now? [Y/n] y

All done!

The latest MariaDB servers comes with root user is set to use the auth_socket authentication method by default.

The auth_socket plugin authenticates users that connect from the localhost through the Unix socket file. This means that you can’t authenticate as a root by providing a password.

This can cause issues with some apps that need to connect to the database via root. To fix that, you’ll need to change the default authentication mechanism from auth_socket to mysql_native_password.

However, doing so might introduce security risks since root users shouldn’t be used to connect remotely to the database. A recommended method is to create a dedicated user to connected remotely to your database servers.

Since you don’t want to connect to MariaDB database server from phpMyAdmin as root user, you should probably create a separate account instead of connecting with root.

Run the commands below to logon to MariaDB server.

sudo mysql -u root -p

Then run the SQL commands below to create a new user for Ghost to use to connect to the database.

CREATE USER 'ghostadmin'@'localhost' IDENTIFIED BY 'very_strong_password_here';

Then grant the user full access to manage the database server.

GRANT ALL PRIVILEGES ON *.* TO 'ghostadmin'@'localhost' WITH GRANT OPTION;

If you see a similar screen as shown above, then the server was successfully installed.

Create Ghost Database on Ubuntu Linux

Now that you’ve installed all the severs above, continue below to start configuring the servers. First run the commands below to create a blank Ghost database.

To logon to MariaDB, run the commands below.

sudo mysql -u root -p

Then create a database called ghost

CREATE DATABASE ghost;

Next, use the Ghost account created above and give it access to the ghost database.

GRANT ALL ON ghost.* TO 'ghostadmin'@'localhost' WITH GRANT OPTION;

Finally, save your changes and exit.

FLUSH PRIVILEGES;
EXIT;

How to install Node.js on Ubuntu Linux

Since Ghost is based on Node.js run the commands below to download Node.js version 14 LTS packages from its repository

sudo apt install curl
curl -sL https://deb.nodesource.com/setup_14.x | sudo bash -

Next, run the commands below to install Node.js and required packages in order for Ghost to function. Nginx webserver will be needed for this. s

sudo apt install nodejs

Next, run the commands below to include Yarn repository and enable it.

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list

Once the repository is enabled, install yarn with:

sudo apt update
sudo apt-get -o Dpkg::Options::="--force-overwrite" install yarn

How to download and install Ghost

We’ll install Ghost using the official Ghost CLI utility. This utility allows you to install or update Ghost in a single command.

Run the commands below to install Ghost install tool.

sudo yarn global add ghost-cli

We’re going to create a folder for Ghost content in the /var/www/ghost directory. To create the folder run the commands below.

sudo mkdir -p /var/www/ghost

Next, change the folder ownership to your account so you can run the Ghost tool to download Ghost packages.

sudo chown $USER:$USER /var/www/ghost
sudo chmod 775 /var/www/ghost

Next, change into the directory and install Ghost.

cd /var/www/ghost

To start the installation, run the command below. The command will install and configure Ghost, configure Nginx as a reverse proxy , and secure the site with a free let’s encrypt SSL certificate.

ghost install

You should begin to see Ghost changing for packages that are required. Once all is validated, Ghost should begin downloading its package dependencies to install.
