How do I install LogZilla NEO on CoreOS?

When I try to install LogZilla NEO (docker based) on CoreOS, I get:

docker run logzilla/kickstart -p >/usr/bin/logzilla; chmod 755 /usr/bin/logzilla; logzilla install
-bash: /usr/bin/logzilla: Read-only file system
chmod: cannot access '/usr/bin/logzilla': No such file or directory
-bash: logzilla: command not found

I found this: https://coreos.com/os/docs/latest/sdk-disk-partitions.html But am not sure if LogZilla has to be put in /usr/bin?

Solution

  • Welcome to Stackoverflow :)

    The path to the LogZilla binary doesn't matter. In CoreOS, you can make a directory on the server where it is writeable, like /opt/bin.

    So just use the following command:

    mkdir -p /opt/bin/; \ docker run logzilla/kickstart -p >/opt/bin/logzilla; \ chmod 755 /opt/bin/logzilla; \ logzilla install

    Side note: The default ports used to map syslog and http in the LogZilla docker install are 32514, 32601, and 3280 (done intentionally so as not to try and use already-taken ports). But if you are certain the standard syslog/http ports are not in use on the host, you can set this during install, like so:

    logzilla install \ --syslog-port-mapping=tcp/514:514,udp/514:514,tcp/601:601 \ --http-port-mapping=tcp/80:80

    Update: The install process is now much easier. Just use: curl -fsSL https://logzilla.sh | bash
