This does not work, as the chroot environment does not have +access to `/proc`, and therefore exposes very few metrics to Netdata. Additionally, [this +issue](https://github.com/SynoCommunity/spksrc/issues/2758), still open as of 2018/06/24, indicates that the Debian +Chroot package is not suitable for DSM versions greater than version 5 and may corrupt system libraries and render the +NAS unable to boot. + +The good news is that the [64-bit static installer](kickstart-64.md) works fine if your NAS is one that uses the amd64 architecture. It +will install the content into `/opt/netdata`, making future removal safe and simple. + +## Run as netdata user + +When Netdata is first installed, it will run as _root_. This may or may not be acceptable for you, and since other +installations run it as the `netdata` user, you might wish to do the same. This requires some extra work: + +1. Creat a group `netdata` via the Synology group interface. Give it no access to anything. +2. Create a user `netdata` via the Synology user interface. Give it no access to anything and a random password. Assign + the user to the `netdata` group. Netdata will chuid to this user when running. +3. Change ownership of the following directories, as defined in [Netdata + Security](/docs/netdata-security.md#security-design): + +```sh +chown -R root:netdata /opt/netdata/usr/share/netdata +chown -R netdata:netdata /opt/netdata/var/lib/netdata /opt/netdata/var/cache/netdata +chown -R netdata:root /opt/netdata/var/log/netdata +``` + +## Create startup script + +Additionally, as of 2018/06/24, the Netdata installer doesn't recognize DSM as an operating system, so no init script is +installed. You'll have to do this manually: + +1. Add [this file](https://gist.github.com/oskapt/055d474d7bfef32c49469c1b53e8225f) as `/etc/rc.netdata`. Make it + executable with `chmod 0755 /etc/rc.netdata`. +2. Add or edit `/etc/rc.local` and add a line calling `/etc/rc.netdata` to have it start on boot: + +```conf +# Netdata startup +[ -x /etc/rc.netdata ] && /etc/rc.netdata start +``` + +3. Make sure `/etc/rc.netdata` is executable: `chmod 0755 /etc/rc.netdata`. + +[](<>) |
