This article describes the steps to install Known LMS on Ubuntu Linux with Nginx support.
A known Learning Management System (LMS), still in beta, is a social learning platform. It is built on the LAMP / LEMP stack and allows users to create an educational community and empower students to publish, work together, and share across many social platforms.
Some features include allowing students to quickly post to the site, use hashtags, view and edit posts from any device, and many more. It also supports WYSIWYG with strong privacy settings to create space for individuals to share personal thoughts with groups or other users.

How to install Known LMS on Ubuntu Linux with Nginx support
As described above, the Known Learning Management System (LMS), still in beta, is a social learning platform.
Below is how to install it on Ubuntu Linux with Nginx support.
Install Nginx HTTP Server on Ubuntu
Nginx HTTP Server is the second most popular web server in use. Install it since Known LMS needs it.
To install Nginx HTTP on the Ubuntu server, 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
To test the Nginx setup, open your browser and browse to the server hostname or IP address. You should see the Nginx default test page, as shown below. When you see that, then Nginx is working as expected.
http://localhost
Install MariaDB Database Server
MariaDB database server is a great place to start when looking at open-source database servers for Magento. To install MariaDB, run the commands below.
sudo apt-get install mariadb-server mariadb-client
After installing MariaDB, the commands below can stop, start, and enable the service to start when the server boots.
Run these on Ubuntu 16.04 LTS
sudo systemctl stop mysql.service sudo systemctl start mysql.service sudo systemctl enable mysql.service
Run these on Ubuntu 17.10 and 18.04 LTS
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 and disallowing remote root access.
sudo mysql_secure_installation
When prompted, answer the questions below by following the guide.
- Enter current password for root (enter for none): Just press the Enter
- Set root password? [Y/n]: Y
- New password: Enter password
- Re-enter new password: Repeat password
- 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
Restart MariaDB server
Type the commands below to log on to the MariaDB server to test if MariaDB is installed.
sudo mysql -u root -p
Then, type the password you created above to sign on. If successful, you should see a MariaDB welcome message.
Install PHP 7.2-FPM and Related Modules.
PHP 7.2-FPM may not be available in Ubuntu default repositories. To install it, you will have to get it from third-party repositories.
Run the commands below to add the below third party repository to upgrade to PHP 7.2-FPM
sudo apt-get install software-properties-common sudo add-apt-repository ppa:ondrej/php
Then update and upgrade to PHP 7.2-FPM
sudo apt update
Next, run the commands below to install PHP 7.2 and related modules.
sudo apt install php7.2-fpm php7.2-common php7.2-sqlite3 php7.2-curl php7.2-intl php7.2-mbstring php7.2-xmlrpc php7.2-mysql php7.2-gd php7.2-xml php7.2-cli php7.2-zip
After installing PHP 7.2, run the commands below to open Nginx’s PHP default config file.
sudo nano /etc/php/7.2/nginx/php.ini
Then, save the changes on the following lines below in the file. The value below is an ideal setting to apply in your environment.
file_uploads = On allow_url_fopen = On short_open_tag = On memory_limit = 256M upload_max_filesize = 100M max_execution_time = 360 cgi.fix_pathinfo = 0 date.timezone = America/Chicago
After making the change above, please save the file and close it.
After installing PHP and related modules, you must restart Nginx to reload PHP configurations.
To restart Nginx, run the commands below
sudo systemctl restart nginx.service
Create Known Database
Once you’ve installed all the packages required for Known LMS to function, continue below to start configuring the servers.
First, run the commands below to create a Known blank database.
To log on to the MariaDB database server, run the commands below.
sudo mysql -u root -p
Then, create a database called known.
CREATE DATABASE known;
Create a database user called knownuser with a new password
CREATE USER 'knownuser'@'localhost' IDENTIFIED BY 'new_password_here';
Then, grant the user full access to the database.
GRANT ALL ON known.* TO 'knownuser'@'localhost' IDENTIFIED BY 'user_password_here' WITH GRANT OPTION;
Finally, save your changes and exit.
FLUSH PRIVILEGES; EXIT;
Download and Install Known LMS
Run the commands below to download Known LMS content. Then, unzip the download file and move the content to the Nginx default root directory.
cd /tmp && wget http://assets.withknown.com/releases/known-0.9.9.zip sudo mkdir -p /var/www/html/known sudo unzip known-0.9.9.zip -d /var/www/html/known
Next, run the commands below to change the root folder permissions.
sudo chown -R www-data:www-data /var/www/html/known/ sudo chmod -R 755 /var/www/html/known/
Configure Nginx Known LMS Site
Finally, configure the Nginx configuration file for Known LMS. This file will control how users access Known LMS content. Run the commands below to create a new configuration file called known.
sudo nano /etc/nginx/sites-available/known
Then copy and paste the content below into the file and save it. Replace the highlighted line with your domain name and directory root location.
server {
listen 80;
listen [::]:80;
root /var/www/html/anchor;
index index.php index.html index.htm;
server_name example.com www.example.com;
client_max_body_size 100M;
location / {
try_files $uri $uri/ =404;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}
Save the file and exit.
After configuring the VirtualHost above, please enable it by running the commands below.
Enable the Known LMS Site
After configuring the VirtualHost above, please enable it by running the commands below, then restart the Nginx server.
sudo ln -s /etc/nginx/sites-available/known /etc/nginx/sites-enabled/ sudo systemctl restart nginx.service
Next, open your browser, go to the URL, and continue with the installation.
http://example.com/
Start the setup wizard.
Type in the site name and the database connection info.
Known needs a single MySQL database with a user that can connect. They recommend that this is a user you have created just for Known rather than one you share with other applications.
It would be best to create your database before entering the details here. If you’re using a shared host, you may have an option called “MySQL Database Wizard” to speed you through the process.
Create the admin account to complete the setup.
Enjoy!
