Install the latest version of Git from source.

October CMS needs PHP version 7.0 or higher compiled with cURL, PDO, OpenSSL, Mbstring, ZipArchive and GD PHP Library enabled. Don't forget to add appropriate DB library: php-mysql for MySQL, php-pgsql for PostgreSQL, etc. Like that:

yum install php-cli php-fpm php-pdo php-common php-curl php-json php-zip php-gd php-xml php-mbstring php-pgsql

• Install any database server from the list: MySQL, MariaDB, PostgreSQL or SQLite.
• Create database for October CMS back-end named '<your-db-name>'.

To allow October CMS to log in to your PostgreSQL server find pg_hba.conf file and add following lines to the beginning of table in the end of the file:

local   <your-db-name>      all                                     trust
host    <your-db-name>      all             127.0.0.1/32            trust
host    <your-db-name>      all             ::1/128                 trust

• Ensure Apache HTTP server (httpd) is installed.
• Add directory for your October CMS in its public folder. For example: /var/www/myoctober.
• Configure Apache's directory root to /var/www/myoctober:

DocumentRoot "/var/www/myoctober"
<Directory "/var/www/myoctober">
    AllowOverride All
    Require all granted
</Directory>

• Download October CMS install wizard archive and extract it into /var/www/myoctober.
• Grant writing permissions (for apache user) on the installation directory and all its subdirectories and files.
• In your web browser navigate to <server-path>/install.php.
• Follow the installation instructions.
• Delete the installation files for security reasons: installation directory install_files/ and installation script install.php.

• In your web browser navigate to <server-path>/backend and log in as admin.
• Navigate to Settings -> Front-end theme.
• 'Create new blank theme' with name 'lsfusion'. This will create folder /var/www/myoctober/themes/lsfusion.
• 'Activate' lsfusion theme.
• Checkout source files from lsFusion theme GitHub repository into /var/www/myoctober/themes/lsfusion.

The easiest way is to install one of Windows distributions that contain Apache, PHP, MySQL and other applications in a single installation file, e.g. XAMPP, WampServer or Web.Developer. WampServer has been successfully tested. Configuration is similar to the described CentOS configuration. Then you can work with source files in the lsfusion theme folder in your editor.
