How to Install Ghost on Ubuntu Linux

How to install Nginx on Ubuntu Linux

Nginx is a popular web server that will help your Ghost blog run smoothly. Installing Nginx on Ubuntu is straightforward and involves a few simple commands to get it set up as a proxy for your Ghost installation.

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 the 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, it has been successfully installed and is running on Ubuntu.

http://localhost

How to install MariaDB on Ubuntu Linux

MariaDB is a reliable, open-source database that Ghost needs to store its content. You can install MariaDB on Ubuntu easily by running a couple of commands in your terminal to get the database server up and running.

To install MariaDB, run the commands below:

sudo apt install mariadb-server

After installing MariaDB, the commands below can stop, start, and enable the service to start 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 the MariaDB server by creating a root password, disallowing remote root access, removing anonymity, 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 have a root user set to use the auth_socket authentication method by default.

The auth_socket plugin authenticates users that connect from the local host through the Unix socket file. 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 connect remotely to your database servers.

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

Run the commands below to log on to the MariaDB server.

sudo mysql -u root -p

Then, run the SQL commands below to create a new user for Ghost 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;

The server was successfully installed if you see a similar screen.

Create Ghost Database on Ubuntu Linux

With MariaDB installed, you’ll need to create a specific database for your Ghost blog to use. Creating a Ghost database on Ubuntu involves logging into MariaDB and running a simple command to set up the new database.

To log on 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

Ghost runs on Node.js, so you’ll need to install it on your Ubuntu system. Installing Node.js on Ubuntu is done using package management commands, ensuring you have the correct version needed for Ghost to function properly.

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 the required packages for Ghost to function. An Nginx webserver will be needed for this. s

sudo apt install nodejs

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

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 the following:

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

How to download and install Ghost

The Ghost CLI is a command-line tool that makes installing and managing Ghost simple. To get started, you’ll first install the Ghost CLI on your Ubuntu system using Yarn, which is a package manager for Node.js.

Run the commands below to install the Ghost install tool.

sudo yarn global add ghost-cli

We will 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, 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.
