LiveAgent Requirements

Before you order LiveAgent, please check if your server meets the following requirements:

  • PHP 8.2 (since application version 5.42)
    - with extensions:  MySQL PDO, gd2, exif, iconv, mbstring, php-json, php-xml, PHP5-CURL package, bcmath, fileinfo
    - required cron PHP max_execution_time set to 0,
    - recommended minimal memory_limit 128MB, recommended 256MB, for cron recommended 512MB
    - recommended web PHP minimal max_execution_time 30 seconds,
    - enabled php session,
  • MariaDB 10.2 or higher (recommended MariaDB 10.4)
    In case of MariaDB 10.6 you need to disable innodb_read_only_compressed which is enabled by default.
  • Web server Apache, Nginx or any other, which supports PHP, .htaccess and mod_rewrite
  • Operating system any Unix like, Windows or Mac (basically all operating systems are supported if the operating system supports the 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)
  • cUrl version 7.39 or higher (older versions cause a problem when connecting to our license server)
  • SSL -  since version 5.25 it's mandatory to use SSL certificate and https://
  • WkHtmlToPdf tool (this is only required for one specific LiveAgent feature to work properly, exporting tickets to PDF. Detailed info here.)
  • ElasticSearch - since version 5.44 is mandatory
    With the release of LiveAgent version 5.44, using ElasticSearch for full-text search has become a mandatory requirement for all installations. Previously, the use of ElasticSearch was optional, though recommended. The minimum supported version of ElasticSearch is 7.16.1. ElascticSearch 8 is not yet supported. Find more about ElasticSearch in this article. 

    Recommended Browser requirements:
    LiveAgent runs on all major browsers. For the best security and functionality, keep your web browser up to date. All modern browsers should update automatically. The minimum browser requirements are:

    • LiveAgent admin / agent panel
      • Microsoft Edge - latest two versions
      • Google Chrome - latest two versions
      • Safari - latest two versions
      • Opera - latest two versions
      • Mozilla Firefox - latest two versions
    • LiveAgent widgets and visitor pages
      • We try to keep the backward compatibility of our widgets also for older versions, so your customers will be able to reach your support team even from older browsers. Anyhow, since version 5.26 we no longer support our widgets in IE11 and we recommend using other browsers.
      • In case you observe any issue, let us know via support@liveagent.com
    Recommended setup of server:
    - 4 Cores @ 3.2GHZ Turbo
    - 8GB RAM (DDR3)
    - 2x 128GB SSD raid1
     

    NOTE: The directory, to which you are about to install Live Agent must be available via browser by some  URL address or IP  ( e.g.  mywebsite.com/liveagent )

    Example configuration
     
    APPLICATION (WEB) SERVER CONFIGURATION
    Processor: Intel Dual Xeon E5-2620 Hexa Core (Romley) 2.0Ghz per Core
    RAM: 64GB DDR3 SDRAM
     
    MYSQL DATABASE SERVER CONFIGURATION
    Processor: Intel Dual Xeon E5-2620 Hexa Core (Romley) 2.0Ghz per Core
    RAM: 32GB DDR3 SDRAM
     
    NOTE: The application server and database server must be running on separate machines in this case.
     
     
    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
