Prerequisites

Cachet requires a few things to run. You’ll need:
  • PHP 7.1 with ext-gd, ext-simplexml, mcrypt and ext-xml installed.
  • Composer
  • APC or Redis for caching.
  • A database such as MySQL, PostgreSQL or SQLite.
  • Git (optional depending on installation)

​
Composer

You should install Composer globally. This is a dependency manager for PHP and is used to install Cachet’s dependencies. We recommend following Composer’s own installation guide. Once Composer is installed, you can install the dependencies. 
composer install --no-dev -o

​
Installing Cachet

The tags below are examples of what will be shown. You should always run git checkout on the latest tag.
cd /var/www # Or wherever you chose to install web applications to
git clone https://github.com/cachethq/Cachet.git
cd Cachet
git tag -l

v0.1.0-alpha
v1.0.0
v1.1.0
v2.0.0
v2.1.0

git checkout v2.1.0

​
Configuring a database

By default, Cachet comes with a .env.example file. You’ll need to rename this file to just .env regardless of what environment you’re working on. It’s now just a case of editing this new .env file and setting the values of your setup.
Any values with spaces in them should be contained within double quotes.
APP_ENV=production
APP_DEBUG=false
APP_URL=http://localhost
APP_KEY=SomeRandomString

DB_DRIVER=mysql
DB_HOST=localhost
DB_DATABASE=cachet
DB_USERNAME=homestead
DB_PASSWORD=secret
DB_PORT=null

CACHE_DRIVER=apc
SESSION_DRIVER=apc
QUEUE_DRIVER=sync
CACHET_EMOJI=false

MAIL_DRIVER=smtp
MAIL_HOST=mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ADDRESS=null
MAIL_NAME="Demo Status Page"
MAIL_ENCRYPTION=tls

REDIS_HOST=null
REDIS_DATABASE=null
REDIS_PORT=null

GITHUB_TOKEN=null
If you’re using SQLite then your .env file should not contain a DB_HOST key. You’ll also need to touch ./database/database.sqlite and give it the required permissions.

​
Setting the application key

Before going any further, we need to set the APP_KEY config. This is used for all encryption used in Cachet. 
php artisan key:generate
Be sure that you have the right permissions to the .env file before running this command.

​
Using the install command

Cachet comes with an installation command that will do the following for you:
  • Run migrations
  • Run seeders (of which there are none)
php artisan app:install
Never change the APP_KEY after installation on production environment. This will result in all encrypted/hashed data being lost.

Installation Difficulties

​
500 - Internal Server Error

If you see a 500 error when visiting your status page, you may need to run chmod -R 777 storage for it to work or rm -rf bootstrap/cache/* You can also try to give permissions to cache chmod -R 777 bootstrap/
