Adding a Mirror Server

A Mirror server hosts a copy of the original index from the Master server (see About Mirror Servers). After commissioning a server and installing a Mirror server software, you must configure the Coveo Master server to use and synchronize the index on the Mirror server.

Before proceeding with the following procedure, ensure that the CES mirror components are installed on the Mirror server (see Installing CES Mirror Components).

To configure the Master server to synchronize a Mirror server

  1. Using an administrator account, connect to the Coveo Master server.

  2. Access the Administration Tool (see Opening the Administration Tool).

  3. In the Administration Tool, select Index > Mirrors.

  4. In the Mirrors page, click Add.

  5. In the Add Mirror page:

    1. In the Name box, enter the exact name that you entered in the Mirror name box in the installer Mirror Configuration screen when the Mirror components were installed (see Installing CES Mirror Components). By default, this is the hostname of the Mirror server.

    2. In the Location box, enter the IP address, the host name, or the fully qualified domain name (FQDN) of the server on which the Coveo Mirror components are installed. 

    3. In the Port box, enter the port number that you specified when you installed the Mirror components (see About the CES Service Port). The default value is 52800.

    4. In the Index Folder box, enter the path of the folder that will contain the index files on the Mirror server. The default path is built using the hostname.

      Example: You can replicate the folder structure as on the Master server using the form [same_Drive]:\CES7\Index\[Mirror_Hostname]. When the default slice is on the D: drive on the Master server and your Mirror server hostname is CoveoMirror1, enter D:\CES7\Index\CoveoMirror1.

    5. Beside Converter, clear the Create a converter on a mirror server check box only when you do not want to use this serve as an additional converter, for example because other converters are already installed on other servers.

      Note: By default, remote converter components are installed on the Mirror server to share CPU resources during the conversion of documents and, therefore, speed up indexing (see Installing CES Mirror Components).

    6. In the Slices section, you can select the location of the slice files on the mirror server: 

      1. In the Default box, when needed, change the path for the folder containing the index files for the Default slice.

      2. When your Coveo instance has more than one slice (not just the Default), for each additional slice, when needed, edit the path for the folder containing the index files for the slice.

    7. When one or more remote indexes are defined in this Coveo instance, in the Remote Indexes section, for each remote index:

      1. In the Mirror Hostname box, enter the hostname of the remote index Mirror server that will execute the queries executed on the Mirror server that you are creating.

      2. In the Mirror Port box, when different from the default value (52800), enter the remote index Mirror server port number.

    8. Click Save.

  6. In the General page that appears for this mirror, in the Status section, click [Synchronize] to start synchronizing the index on the Mirror server.

    Note: CES 7.0.7183+ (November 2014) You can synchronize a mirror (other than the Default) even when its status is In Sync.

    Forcing a synchronization may be useful in rare cases such as when you need to isolate a Mirror server for external reasons or when you realize your Mirror server did not have the same access as the Master server for the security cache updates.

  7. Under Synchronize Mirrors:

    1. In the Synchronize from drop-down list, select Default on localhost unless you have another in sync mirror from which you want to synchronize the index.

    2. Select Use compression only when the connection between the Master and Mirror servers is slow such as when the servers are connected through a WAN in a GDI configuration. Compression requires more CPU resources.

    3. Click OK.

  8. In the General page that appears again, in the Status section, you can monitor mirror synchronization progress, and can abort it if needed by clicking [Cancel Synchronize].

    When the synchronization is completed, the Mirror is in sync status appears.

What's Next?

Once your Mirror server is up and running and synchronized with the Master server, the next step is to let Front-End servers know that they can send queries to this server (see Coveo .NET Front-End First Time Setup).
