Custom Installation Example: Two Servers

The following describes one possibility for configuring PureMessage using the Custom Install option. See "Server Deployment Options" for other examples.

In this installation, the first server hosts the Centralized Server Manager role, the Database Server role and the End User Web Interface Server role. The second server hosts both the Mail Transfer Agent role and the Mail Filter role.

Important:
  • In a custom installation you must install and run the Centralized Server Manager role first and the Database Server role second. Only then should you install roles on additional servers.
  • It is recommended that you install the Mail Transfer Agent role on both the central server and the edge server that you plan to use as your mail server (as described in this example). If you intend to install the Mail Transfer Agent role on a server that is separate from the one on which the Centralized Server Manager role is installed, you must specify the hostname and port number of the mail server so that the central server will be able to send it administrative notifications and messages that are released from the quarantine. You will be prompted to provide the hostname and port as one of the Custom Installation steps.
  • To ensure consistent reporting across multiple servers, use ntp synchronization with ntpd so that the system clock is the same on all servers. In addition, all servers must be set to the same time zone for accurate reporting.
  • It is recommended that you specify the same username for the PureMessage user on each server in your deployment. If you use different usernames, you must manually configure the DSN string.

To install this multi-server configuration, complete the steps in the order described below.
