# Minimum System Requirements

Before installing October CMS, ensure the target system meets the minimum requirements:

  • PHP version 8.0.0 or higher
  • Composer 2.0 or higher
  • PDO PHP Extension
  • cURL PHP Extension
  • OpenSSL PHP Extension
  • Mbstring PHP Extension
  • ZipArchive PHP Extension
  • GD PHP Extension
  • SimpleXML PHP Extension.

Supported database servers:

  • MySQL 5.7 or MariaDB 10.2. For older versions of MySQL or MariaDB, you may need to configure the index lengths to support the utf8mb4 character set.
  • PostgreSQL 9.6
  • SQLite 3.8.8.

Supported web servers:

  • Apache
  • Nginx
  • Lighttpd
  • Microsoft IIS

# Installing October CMS

You should configure a virtual host on the web server to access the installation directory. For local development you can use Laravel Sail, Valet (opens new window), Laragon (opens new window) or the built-in Laravel development server.

October CMS is a PHP web application that uses Composer (opens new window) to manage its dependencies. Ensure that Composer is installed before you begin. The License Key (opens new window) will be required to complete the installation.

To install the platform, initialize a project using the create-project command in the terminal. The following command creates a new project in a directory called myoctober:

composer create-project october/october myoctober

When the command finishes, enter the project directory:

cd myoctober

Run the installation command:

php artisan october:install

The last step is the migration command that will initialize the database. Alternatively, October CMS can initialize the database when you first access the backend panel.

php artisan october:migrate

When the process finishes, you can access the backend panel in a browser and create the administrator user profile. If you are using the built-in web server, you can launch it with the following command:

php artisan serve

If you are installing the platform on a production web server, review the recommendations listed in the Production Configuration article.

# Wizard Installation

Wizard Tutorial

This video guides you through the process of installing October CMS using the easy-to-use Wizard installer.

Watch the tutorial

The wizard installation is an alternative way to install October CMS without using Composer. It is simpler than the command-line installation and doesn't require any special skills.

  1. Prepare a directory on your server that is empty. It can be a sub-directory, domain root or a sub-domain.
  2. Download the installer archive file (opens new window).
  3. Unpack the installer archive to the prepared directory.
  4. Grant writing permissions on the installation directory and all its subdirectories and files.
  5. Navigate to the install.php script in your web browser.
  6. Follow the installation instructions.


# Troubleshooting Installation

Several typical issues can occur during or after installation.

The installation freezes after entering the license key

It can happen in some environments when pasting the license key contents. Press the ENTER key several times to allow the installation process to continue.

An error "Unable to get local issuer certificate" is displayed during installation

The complete error may read cURL error 60: SSL certificate problem: unable to get local issuer certificate.

Download this certificate file (opens new window) and save it as cacert.pem. Open your php.ini file and insert or edit the following line. You may need to restart Apache for the changes to take effect.

curl.cainfo = "/path/to/cacert.pem"
An error "Specified key was too long" is displayed during migration

The complete error may read SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes

This can happen with older versions of MySQL or MariaDB. Configuring the index lengths to support the utf8mb4 character set can help to resolve this issue.

A blank screen is displayed when opening the application

Check the permissions are set correctly on the /storage files and subdirectories. They must be writable for the web server.

Invalid security token error when logging in

Check to ensure no missing subdirectories in the storage/framework path. You may need to add the sessions, cache and views directories (opens new window).

The backend panel displays "Page not found" (404)

If the application cannot find the database then a 404 page will be shown for the back-end. Try enabling debug mode to see the underlying error message.

An error 500 is displayed when updating the application

The request timeout on the web server should be increased or disabled. For example, Apache's FastCGI sometimes has the -idle-timeout option set to 30 seconds.

Zend OPcache API is restricted by "restrict_api" configuration directive

This issue can appear when internals try to use the OPcache internals. This can be disabled by setting the force_bytecode_invalidation configuration to false inside the config/cms.php file.
