Requirements

For the installation of a LiveConfig server you need:

  • “root access” at the server to be installed (via console or SSH)

  • about 30 MB free disk space

  • a current web browser

Please also check for:

  • correct time: you need the correct time on your server - otherwise you might experience problems with SSL certificates, outbound e-mail and validity of the LiveConfig license. We recommend to install the package ntp (Network Time Protocol).

  • valid host name & reverse DNS: the server requires a valid host name. Using the command hostname -f you’ll see the complete (fully-qualified) name. This consists of a host name and a domain name.

    Example: for a web server with the name www.example.org, the file /etc/hostname should contain only www; in /etc/hosts there should be a line with <IP address>  <complete name>  <hostname>, in this case ##.##.##.##  www.example.org  www. If everything is configured correctly, the command hostname (without any options) will return just www, and hostname -f will return www.example.org.

    A valid reverse DNS name is especially important if you want to send e-mails with your server. Most mail servers check if the name of the peer mail server matches its reverse DNS name.

File system quota

If you want to use the server for webspace, it’s recommended to enable file system quota. This is required to limit and to check the disk space used by webhosting subscriptions.

See the Knowledge Base for details on enabling file system quota.

Firewall settings

If the server being installed is protected by a firewall, the following ports have to be configured to allow incoming connections:

  • TCP port 8443 (for HTTPS access)

  • optional: TCP port 788 (if LiveConfig clients should connect to this server)

  • optional: TCP port 8080 (if you want to allow unencrypted access via HTTP)

The port settings can be changed arbitrarily in the configuration file.

If you’re also filtering outbound connections, the following destinations must be allowed:

  • TCP port 443 (HTTPS) to the LiveConfig license server (licence.liveconfig.com)

  • optionally: TCP port 443 (HTTPS) to the update server (update.liveconfig.com) for installing web applications, as well as port 80 or 443 to the download server of the respective application.
