LiveAgent Requirements

Before you order LiveAgent, please,  check if your server meets the following recommended minimum requirements:
  • PHP5.6 or higher (PHP7 recommended)
    - with extensions:  MySQL PDO or MySQLi, gd2, iconv, mbstring, php-json, php-xml, PHP5-CURL package
    - recommended minimal memory_limit 32MB,
    - recommended minimal max_execution_time minimum 30 seconds
    - enabled php session
    • If you want to use PHP5.x with PDO database driver, you must explicitly specify it by adding "DB_DRIVER=Pdo" on a separate line in /accounts/settings.php
    • In PHP7 PDO is used automatically
       
  • MySql 5.5.3 or higher (recommended MySql 5.6 which adds support for FULLTEXT indexes)
    Fully supported are also MariaDB 10.0.5 and Percona 5.6 (or higher). Here you can read how you can easily check your version.
    • without SQL mode ONLY_FULL_GROUP_BY
  • Web server Apache, IIS or any other, which supports PHP and .htaccess (IIS can support .htaccess via http://www.helicontech.com/ape/ )
  • Operating system any Unix like, Windows or Mac (basically all operating systems are supported if the operating system supports installation of web servers)
  • Disk space - absolute minimum 300 MB, plan ahead space required for your data (all emails, attachments, chats, tickets are stored in the database)
  • SSL - it is supported so if you own an SSL certificate you can use https://
  • WkHtmlToPdf tool (this is only required for one specific LiveAgent feature to work properly, exporting tickets to PDF. Detailed info here.)

Example configuration

NOTE: We do not recommend GoDaddy's shared hosting due to their weird fast_cgi limits that may cause the entire site go down temporarily if the limit is exceeded. Exceeding that limit results in having the error logs full of the following log entry:
fcgid:warn] (9)Bad file descriptor: [client xxx.xxx.xxx.xxx:xxxxx] mod_fcgid: ap_pass_brigade failed in handle_request_ipc function
