2.3.2 Installation
2.3.2.1 Installation at headquarters
Installations of ERAS, ERAC and client workstations are very similar to the previous scenario. The only difference is in
the configuration of the master ERAS (GHOST). In
Tools
>
Server Options…
>
Replication
select the
Enable “from” replication
check box and enter the name of the secondary server in
Allowed servers
. In our case, the
lower server is named LITTLE.
If there is a password for replication set on the upper server (
Tools
>
Server Options…
>
Security
>
Password for replication
), then that password must be used for authentication from the lower server.
2.3.2.2 Branch office: Installation of ERA Server
As in the example directly above, install the second ERAS and ERAC. Again, enable and configure the replication
settings. This time select the
Enable “to” replication
check box (
Tools
>
Server Options…
>
Replication
) and define
the name of the master ERAS. We recommend using the IP address of the master server, which is the IP address of the
server GHOST.
2.3.2.3 Branch office: Installation of HTTP Mirror server
The Mirror server installation configuration in the previous scenario can also be used in this case. The only changes are
in the sections defining the username and password.
As in the figure from
Environment overview
chapter, updates for the branch office are not downloaded from ESET’s
update servers, but from the server at the headquarters (GHOST). The update source is defined by the following URL
address:
http://ghost:2221 (or http://IP_address_of_ghost:2221)
By default, there is no need to specify a username or password, because the integrated HTTP server requires no
authentication.
For more information on configuring the Mirror in ERAS, see the chapter titled
Mirror Server
.
2.3.2.4 Branch office: Remote installation to clients
Once more, the previous model can be used, except that it is suitable to perform all operations with the ERAC
connected directly to the ERAS of the branch office (in our example: LITTLE). This is done to prevent installation
packages from being transferred via the VPN channel, which is slower.
