To get started with installing Cachet, follow the steps below:

Step 1: Install Apache2 HTTP Server

Cachet requires a web server and Apache2 HTTP server is the most popular open source web server available today… To install Apache2 server, run the commands below:

sudo apt update
sudo apt install apache2

After installing Apache2, the commands below can be used to stop, start and enable Apache2 service to always start up with the server boots…

sudo systemctl stop apache2.service
sudo systemctl start apache2.service
sudo systemctl enable apache2.service

Now that Apache2 is installed…. to test whether the web server is working, open your browser and browse to the URL below…

http://localhost

If you see the page above, then Apache2 is successfully installed…

Step 2: Install MariaDB Database Server

Cachet also requires a database server to store its content… 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-get install mariadb-server mariadb-client

After installing MariaDB, the commands below can be used to stop, start and enable MariaDB service to always start up 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 18.10 and 18.04 LTS

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

Next, run the commands below to secure the database server with a root password if you were not prompted to do so during the installation…

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

Now that MariaDB is installed, to test whether the database server was successfully installed, run the commands below…

sudo mysql -u root -p

type the root password when prompted…

mariadb welcome

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

Step 3: Install PHP 7.2 and Related Modules

Cachet is a PHP based CMS and PHP is required… However, PHP 7.2 may not be available in Ubuntu default repositories… To run PHP 7.2 on Ubuntu 16.04 and previous, you may need to run the commands below:

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ondrej/php

Then update and upgrade to PHP 7.2

sudo apt update

Next, run the commands below to install PHP 7.2 and related modules.

sudo apt install php7.2 libapache2-mod-php7.2 php7.2-common php7.2-mysql php7.2-gmp php7.2-curl php7.2-intl php7.2-mbstring php7.2-xmlrpc php7.2-gd php7.2-bcmath php7.2-imap php7.2-xml php7.2-cli php7.2-zip

After installing PHP 7.2, run the commands below to open PHP default configuration file for Apache2…

sudo nano /etc/php/7.2/apache2/php.ini

The lines below is a good settings for most PHP based CMS… Update the configuration file with these and save….

file_uploads = On
allow_url_fopen = On
short_open_tag = On
memory_limit = 256M
upload_max_filesize = 100M
max_execution_time = 360
date.timezone = America/Chicago

Everytime you make changes to PHP configuration file, you should also restart Apache2 web server… To do so, run the commands below:

sudo systemctl restart apache2.service

Now that PHP is installed, to test whether it’s functioning, create a test file called phpinfo.php in Apache2 default root directory…. ( /var/www/html/)

sudo nano /var/www/html/phpinfo.php

Then type the content below and save the file.

<?php phpinfo( ); ?>

Next, open your browser and browse to the server’s hostname or IP address followed by phpinfo.php

http://localhost/phpinfo.php

You should see PHP default test page…

Step 4: Create Cachet Database

Now that you’ve installed all the packages that are required for Cachet to function, continue below to start configuring the servers. First run the commands below to create a blank Cachet database.

To logon to MariaDB database server, run the commands below.

sudo mysql -u root -p

Then create a database called cachetdb

CREATE DATABASE cachetdb;

Create a database user called cachetdbuser with a new password

CREATE USER 'cachetdbuser'@'localhost' IDENTIFIED BY 'new_password_here';

Then grant the user full access to the database.

GRANT ALL ON cachetdb.* TO 'cachetdbuser'@'localhost' IDENTIFIED BY 'user_password_here' WITH GRANT OPTION;

Finally, save your changes and exit.

FLUSH PRIVILEGES;
EXIT;

Step 5: Download Cachet Latest Release

To get Cachet latest release you may want to use Github repository… Install git tool to download Cachet packages…..

sudo apt install curl git
curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer

After installing curl above, change into the Apache2 root directory and download Cachet packages from Github…

cd /var/www/html
sudo git clone -b 2.4 --single-branch https://github.com/cachethq/Cachet.git cachet

Next the commands below to create Cachet .env file..

sudo cp /var/www/html/cachet/.env.example /var/www/html/cachet/.env

<VirtualHost *:80>
     ServerAdmin admin@example.com
     DocumentRoot /var/www/html/cachet/public
     ServerName example.com
     ServerAlias www.example.com

     <Directory /var/www/html/cachet/public>
          Options FollowSymlinks
          AllowOverride All
          Require all granted
     </Directory>

     ErrorLog ${APACHE_LOG_DIR}/error.log
     CustomLog ${APACHE_LOG_DIR}/access.log combined
    
     <Directory /var/www/html/cachet/public>
            RewriteEngine on
            RewriteBase /
            RewriteCond %{REQUEST_FILENAME} !-f
            RewriteRule ^(.*) index.php [PT,L]
    </Directory>
</VirtualHost>

Save the file and exit.

Step 7: Enable the Cachet and Rewrite Module
