All of the configuration files for October are stored in the config/ directory. Each option is documented, so feel free to look through the files and get familiar with the options available to you.

Web server configuration

October has basic configuration that should be applied to your webserver. Common webservers and their configuration can be found below.

Apache configuration

If your webserver is running Apache there are some extra system requirements:

  1. mod_rewrite should be installed
  2. AllowOverride option should be switched on

In some cases you may need to uncomment this line in the .htaccess file:

## You may need to uncomment the following line for some hosting environments,
## if you have installed to a subdirectory, enter the name here also.
# RewriteBase /

If you have installed to a subdirectory, you should add the name of the subdirectory also:

RewriteBase /mysubdirectory/

Nginx configuration

There are small changes required to configure your site in Nginx.

nano /etc/nginx/sites-available/default

Use the following code in server section. If you have installed October into a subdirectory, replace / with the directory October was installed under:

location / {
    try_files $uri /index.php$is_args$args;

rewrite ^themes/.*/(layouts|pages|partials)/.*.htm /index.php break;
rewrite ^bootstrap/.* /index.php break;
rewrite ^config/.* /index.php break;
rewrite ^vendor/.* /index.php break;
rewrite ^storage/cms/.* /index.php break;
rewrite ^storage/logs/.* /index.php break;
rewrite ^storage/framework/.* /index.php break;
rewrite ^storage/temp/protected/.* /index.php break;
rewrite ^storage/app/uploads/protected/.* /index.php break;

Lighttpd configuration

If your webserver is running Lighttpd you can use the following configuration to run OctoberCMS. Open your site configuration file with your favorite editor.

nano /etc/lighttpd/conf-enabled/sites.conf

Paste the following code in the editor and change the host address and server.document-root to match your project.

$HTTP["host"] =~ "" {
    server.document-root = "/var/www/example/"

    url.rewrite-once = (
        "^/(plugins|modules/(system|backend|cms))/(([\w-]+/)+|/|)assets/([\w-]+/)+[-\w^&'@{}[\],$=!#().%+~/ ]+\.(jpg|jpeg|gif|png|svg|swf|avi|mpg|mpeg|mp3|flv|ico|css|js|woff|ttf)(\?.*|)$" => "$0",
        "^/(system|themes/[\w-]+)/assets/([\w-]+/)+[-\w^&'@{}[\],$=!#().%+~/ ]+\.(jpg|jpeg|gif|png|svg|swf|avi|mpg|mpeg|mp3|flv|ico|css|js|woff|ttf)(\?.*|)$" => "$0",
        "^/storage/app/uploads/public/[\w-]+/.*$" => "$0",
        "^/storage/temp/public/[\w-]+/.*$" => "$0",
        "^/(favicon\.ico|robots\.txt|sitemap\.xml)$" => "$0",
        "(.*)" => "/index.php$1"

IIS configuration

If your webserver is running Internet Information Services (IIS) you can use the following in your web.config configuration file to run OctoberCMS.

<?xml version="1.0" encoding="UTF-8"?>
                <rule name="redirect all requests" stopProcessing="true">
                    <match url="^(.*)$" ignoreCase="false" />
                    <conditions logicalGrouping="MatchAll">
                        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" pattern="" ignoreCase="false" />
                    <action type="Rewrite" url="index.php" appendQueryString="true" />

Application configuration

Debug mode

The debug setting is found in the config/app.php configuration file with the debug parameter and is enabled by default.

When enabled, this setting will show detailed error messages when they occur along with other debugging features. While useful during development, debug mode should always be disabled when used in a live production site. This prevents potentially sensitive information from being displayed to the end-user.

The debug mode uses the following features when enabled:

  1. Detailed error pages are displayed.
  2. Failed user authentication provides a specific reason.
  3. Combined assets are not minified by default.
  4. Safe mode is disabled by default.

Important: Always set the app.debug setting to false for production environments.

Safe mode

The safe mode setting is found in the config/cms.php configuration file with the enableSafeMode parameter. The default value is null.

If safe mode is enabled, the PHP code section is disabled in CMS templates for security reasons. If set to null, safe mode is on when debug mode is disabled.

CSRF protection

October provides an easy method of protecting your application from cross-site request forgeries. First a random token is placed in your user's session. Then when a opening form tag is used the token is added to the page and submitted back with each request.

While CSRF protection is disabled by default, you can enable it with the enableCsrfProtection parameter in the config/cms.php configuration file.

Bleeding edge updates

The October platform and some plugins will implement changes in two stages to ensure overall stability and integrity of the platform. This means they have a test build in addition to the default stable build.

You can instruct the platform to prefer test builds by changing the edgeUpdates parameter in the config/cms.php configuration file.

| Bleeding edge updates
| If you are developing with October, it is important to have the latest
| code base, set this value to 'true' to tell the platform to download
| and use the development copies of core files and plugins.

'edgeUpdates' => false,

Note: For plugin developers we recommend enabling Test updates for your plugins listed on the marketplace, via the Plugin Settings page.

Environment configuration

It is often helpful to have different configuration values based on the environment the application is running in. You can do this by setting the APP_ENV environment variable which by default it is set to production. There are two common ways to change this value:

  1. Set APP_ENV value directly with your webserver.

    For example, in Apache this line can be added to the .htaccess or httpd.config file:

    SetEnv APP_ENV "dev"
  2. Create a .env file in the root directory with the following content:


In both of the above examples, the environment is set to the new value dev. Configuration files can now be created in the path config/dev and will override the application's base configuration.

For example, to use a different MySQL database for the dev environment only, create a file called config/dev/database.php using this content:


return [
    'connections' => [
        'mysql' => [
            'host'     => 'localhost',
            'port'     => '',
            'database' => 'database',
            'username' => 'root',
            'password' => ''

Advanced configuration

Using a public folder

For ultimate security in production environments you may configure your web server to use a public/ folder to ensure only public files can be accessed. First you will need to spawn a public folder using the october:mirror command.

php artisan october:mirror public/

This will create a new directory called public/ in the project's base directory, from here you should modify the webserver configuration to use this new path as the home directory, also known as wwwroot.

Note: The above command may need to be performed with System Administrator or sudo privileges. It should also be performed after each system update or when a new plugin is installed.

Extended environment configuration

As an alternative to the standard environment configuration you may place common values in the environment instead of using configuration files. The config is then accessed using DotEnv syntax. Run the october:env command to move common config values to the environment:

php artisan october:env

This will create an .env file in project root directory and modify configuration files to use env helper function. The first argument contains the key name found in the environment, the second argument contains an optional default value.

'debug' => env('APP_DEBUG', true),

Your .env file should not be committed to your application's source control, since each developer or server using your application could require a different environment configuration.
