How to install on Plesk panel

You are supposed to have a default or close to default Plesk Onyx Linux VPS with a configured website - PHP, MariaDB/MySQL, Nginx as a frontend proxy and SSL enabled.

Requirements

• A managed with Plesk Onyx Linux server (VPS) with SSH access as a root user or with sudo
• A website on this server with PHP, MariaDB/MySQL, Nginx as a frontend proxy and SSL enabled
• telnet installed on the server: apt|yum install telnet
• php_mysqli, php_curl & php_fileinfo extensions, php_json extension on PHP5
• shell_exec enabled in php.ini (how to check / enable shell_exec)

Make sure that PHP shell_exec is enabled: upload and navigate with your browser to a PHP file with the following content:

<?php print(shell_exec('date'));?>

It should display the current date and time. In case of an error or no output, enable shell_exec in php.ini by removing it from the list of disabled functions: disable_functions = exec,passthru,shell_exec,system,proc_open and restart the web server.

php.ini: Plesk » Tools and Settings » PHP Settings >» click on a PHP handler » php.ini tab

• Upload in binary mode - the two files in blabws-server-pro on your computer & remote server must be exactly the same size
• Make sure the server is executable: chmod +x /opt/blabws-server-pro/blabws-server-pro or Filezilla » File Permissions » 755

    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_read_timeout 600s;
    # connection will be closed after 600 seconds of inactivity
    }

and restart Nginx.

CHMOD blabwspro/config.php to 666, blabwspro/attachments to 777, navigate with your browser to YOUR_WEBSITE_URL.COM/blabwspro/index.php and follow the instructions (3 steps only):
