17.2. Procedure – Installing a Munin server on a ZMS host

Purpose: 

If there is no separate Munin server, and Zorp is not preferred to be integrated into the existing Munin environment, install the Munin server on a standalone ZMS host (installing the Munin server on a Zorp or ZCV host is possible, but strongly discouraged). To achieve this, complete the following steps.

Steps: 

1. Login to the host locally, or remotely using SSH. For details on enabling SSH access, see Section 9.4, Local services on Zorp.

2. Install the Munin server and the Lighthttpd webserver packages. The webserver is required to display the resource graphs collected using Munin. Issue the following command: sudo apt install munin lighttpd.

3. Configure the Munin server and the webserver as needed for the actual environment. For details, see the documentation of Munin and Lighthttpd.

   Warning
   By default, access to the Munin graphs does not require authentication. Configure Munin and Lighthttpd to use SSL-encryption, and disable unencrypted HTTP access on port 80. Use port 443, or a non-standard port instead.

4. Login to the ZMS host using ZMC, and enable access to the TCP port configured in the previous step on the ZMS host. For details, see Section 9.4, Local services on Zorp.
