NILThe following guide is a real world example of drist usage. We will
create a script to deploy munin-node on OpenBSD systems.
We need to create a script that will install munin-node package but
also configure it using the default proposal. This is done easily
using the **script** file.
#!/bin/sh
# checking munin not installed
pkg_info | grep munin-node
if [ $? -ne 0 ]; then
pkg_add munin-node
munin-node-configure --suggest --shell | sh
rcctl enable munin_node
fi
rcctl restart munin_node
The script contains some simple logic to prevent trying installing
munin-node each time we will run it, and also prevent re-configuring it
automatically every time. This is done by checking if pkg_info output
contains munin-node.
We also need to provide a **munin-node.conf** file to allow our munin
server to reach the nodes. For this how-to, I'll dump the
configuration in the commands using cat, but of course, you can use
your favorite editor to create the file, or copy an original
mkdir -p files/etc/munin/
cat <<EOF > files/etc/munin/munin-node.conf
log_level 4
log_file /var/log/munin/munin-node.log
pid_file /var/run/munin/munin-node.pid
background 1
setsid 1
user root
group wheel
ignore_file [\#~]$
ignore_file DEADJOE$
ignore_file \.bak$
ignore_file %$
ignore_file \.dpkg-(tmp|new|old|dist)$
ignore_file \.rpm(save|new)$
ignore_file \.pod$
allow ^127\.0\.0\.1$
allow ^192\.168\.1\.100$
allow ^::1$
host *
port 4949
EOF
Now, we only need to use drist on the remote host:
drist root@myserver
Last version of drist as now also supports privilege escalation using
doas instead of connecting to root by ssh:
drist -s -e doas user@myserver
