First: Please consider using a packaged version. Munin is available as packages in the packaging system of many operating systems.
To install munin in /usr/local, install its build requirements, and then run:
make
make test
# run as root or use something like "sudo"
make install
This will install munin master, node and plugins.
For more information about requirements, please see the install
documentation (online) or the files in this repository below doc/installation/
.
