Just follow <code>@hrbrmstr@rud.is<\/code> and the new posts from here will slide right into your timeline.<\/div>\n<p>So, you&#8217;ve committed to abandoning the bird site, joined a ? instance, or three, and are now a citizen of the Fediverse. This is ??! But, what if you want to dig into this brave new universe a bit and see how it works? Or, perhaps you would like to engage with a specific set of other folks without committing to a particular <strike>BBS<\/strike>node?<\/p>\n<p>Running a full-on Mastodon instance means dealing with PostgreSQL, Redis, Ruby (ugh), and NodeJS. Sure, Docker is an option, but this is still a big project, and it&#8217;s <a href=\"https:\/\/www.tiobe.com\/tiobe-index\/ruby\/\">more than likely<\/a> that you&#8217;re not a Ruby programmer (which makes it difficult to poke at the code to bend it to your will).<\/p>\n<p>What if I told you there&#8217;s a way to run your own <a href=\"https:\/\/activitypub.rocks\">ActivityPub<\/a> (et al.) server that:<\/p>\n<ul>\n<li>is built with Golang (requires libsqlite3)<\/li>\n<li>uses SQLite for persistence<\/li>\n<li>compiles in seconds<\/li>\n<li>sets up in minutes<\/li>\n<li>takes almost no system resources<\/li>\n<li>supports custom emojis<\/li>\n<li>allows markdown in posts (including source code block syntax highlighting)<\/li>\n<li>features location check-ins (like Foursquare back in the old days)<\/li>\n<li>enables filtering and censorship (for abuse prevention)<\/li>\n<li>sports a tiny but quite useful API<\/li>\n<li>lets folks consume your activity stream as an RSS feed<\/li>\n<\/ul>\n<p>If that sounds more to your liking, let me introduce you to <a href=\"https:\/\/humungus.tedunangst.com\/r\/honk\">Honk<\/a> by Ted Unangst (&#64;tedu&commat;honk.tedunangst.com), and walk you through <a href=\"https:\/\/honk.hrbrmstr.de\">my Honk<\/a> (&commat;bob&commat;honk.hrbrmstr.de) setup.<\/p>\n<h3>Prepare To Honk<\/h3>\n<p>You can either use <a href=\"https:\/\/www.mercurial-scm.org\">Mercurial<\/a> and:<\/p>\n<pre><code class=\"language-bash\">$ hg clone https:\/\/humungus.tedunangst.com\/r\/honk\n<\/code><\/pre>\n<p>or <a href=\"https:\/\/humungus.tedunangst.com\/r\/honk\/d\">grab a tarball<\/a> and expand it (do either of these things on the box you will be running Honk). Then, just:<\/p>\n<pre><code class=\"language-bash\">$ cd honk\n$ make\n<\/code><\/pre>\n<p>and in a few seconds you&#8217;ll have a <code>honk<\/code> server binary ready to use.<\/p>\n<p>Now, you&#8217;re also going to need a &#8220;TLS terminating reverse proxy&#8221;. We&#8217;ll be using <a href=\"http:\/\/nginx.org\">Nginx<\/a> since it is nigh ubiquitous and straightforward to setup. If you&#8217;ve never set up an HTTPS Nginx instance. Nginx <a href=\"https:\/\/www.nginx.com\/resources\/wiki\/start\/topics\/tutorials\/install\/\">drops in nicely<\/a> almost everywhere, and <a href=\"https:\/\/haydenjames.io\/how-to-set-up-an-nginx-certbot\/\">this isn&#8217;t a terrible certbot\/nginx &#8216;splainer<\/a>. The rest of this drop assumes you have an Nginx instance ready to configure for honking.<\/p>\n<p>I&#8217;m hosting my actual Honk instance on an overkill home data science server (you can use a Raspberry Pi to run Honk), which is exposed to one of my internet-facing Nginx reverse proxy servers via <a href=\"https:\/\/tailscale.com\">Tailscale<\/a>. Using a setup like this means you can go super-cheap ($5\/mo) on a <a href=\"https:\/\/en.wikipedia.org\/wiki\/Virtual_private_server\">VPS<\/a>. You can also 100% just run Honk on the same internet-facing box as you do Nginx, just make sure to follow the specific guidance for that setup below, and mebbe spring for a slightly bigger server. FWIW I use <a href=\"https:\/\/www.ssdnodes.com\/manage\/aff.php?aff=415\">SSD Nodes<\/a> (full-disclosure: that is an affiliate link).<\/p>\n<p>Finally, you&#8217;ll need a <a href=\"https:\/\/en.wikipedia.org\/wiki\/Fully_qualified_domain_name\">FQDN<\/a> configured that points to your reverse proxy. Mine is <code>honk.hrbrmstr.de<\/code> which has an <code>A<\/code> record pointing to my internet-facing VPS. Your ActivityPub handle will be <code>@user@ThisFQDNyouChose<\/code>, so pick one you can live with.<\/p>\n<p>Make sure all three of those things are ready for the remaining steps.<\/p>\n<h3>Configure + Run Honk<\/h3>\n<p>This part is pretty straightforward. Run:<\/p>\n<pre><code class=\"language-bash\">$ .\/honk init\n<\/code><\/pre>\n<p>on the box you&#8217;re running Honk from. It&#8217;s going to ask you for four pieces of information:<\/p>\n<ul>\n<li><code>username<\/code>: the username you want. Again, this will be your <code>@username@TheHonkFQDNyouChose<\/code> identity, so pick one you can live with.<\/li>\n<li><code>password<\/code>: the password you want; pick a long passphrase from a password manager generator that you&#8217;ll keep in said password manager. Honk does <em>not<\/em> support MFA. Attackers will find you. You cannot hide. Just make it hard for them.<\/li>\n<li><code>listenaddr<\/code>: host + port Honk will listen on. If running Honk on the same system as Nginx make it something like <code>127.0.0.1:31337<\/code> so Honk itself is only accessible locally. I used my VPS&#8217; Tailscale IP address.<\/li>\n<li><code>servername<\/code>: the FQDN you configured in the previous section.<\/li>\n<\/ul>\n<p>If you mess up, just remove the SQLite databases Honk just made and start over.<\/p>\n<p>Feel free to get all fancy with whatever system service runner you like, but I just run Honk from a custom application directory with:<\/p>\n<pre><code class=\"language-bash\">$ nohup .\/honk &amp;\n<\/code><\/pre>\n<p>You leave out the <code>nohup<\/code> and <code>&amp;<\/code>, or <code>tail -f nohup.out<\/code>, if you want to see the log as you configure Nginx in the next section.<\/p>\n<h3>Configure Nginx<\/h3>\n<p><em>Remember that this bit assumes you&#8217;ve installed Nginx and set it up with a <code>certbot<\/code> TLS certificate. See above for links to resources to help you do that.<\/em><\/p>\n<p>Now you need to tell Nginx where to serve up your honk instance. Modify your base config to look something like this:<\/p>\n<pre><code class=\"language-nginx\">server {\n\n  server_name honk.example.com;\n\n  location \/ {\n    proxy_pass http:\/\/127.0.0.1:31337;\n    proxy_set_header Host $host;\n    proxy_set_header X-Real-IP $remote_addr;\n    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;\n    proxy_set_header X-Forwarded-Proto $scheme; \n  }\n\n  listen 443 ssl; # managed by Certbot\n\n  ssl_certificate \/etc\/letsencrypt\/live\/honk.example.com\/fullchain.pem; # managed by Certbot\n  ssl_certificate_key \/etc\/letsencrypt\/live\/honk.example.com\/privkey.pem; # managed by Certbot\n  include \/etc\/letsencrypt\/options-ssl-nginx.conf; # managed by Certbot\n  ssl_dhparam \/etc\/letsencrypt\/ssl-dhparams.pem; # managed by Certbot\n\n}\n\nserver {\n\n  if ($host = honk.example.com) {\n    return 301 https:\/\/$host$request_uri;\n  } # managed by Certbot\n\n  listen 80;\n\n  server_name honk.example.com;\n\n  return 404; # managed by Certbot\n\n}\n<\/code><\/pre>\n<p>Replace the <code>proxy_pass<\/code>, <code>honk.example.com<\/code>, and <code>127.0.0.1:31337<\/code> values with your specific config.<\/p>\n<p>Restart Nginx and go to <code>honk.example.com<\/code>. If you don&#8217;t see the Honk main page, check the Nginx logs and the Honk logs and give it a go again.<\/p>\n<h3>Go Honkin&#8217; Crazy<\/h3>\n<p>The <a href=\"https:\/\/humungus.tedunangst.com\/r\/honk\/m\">Honk docs<\/a> are useful and quite fun reads.<\/p>\n<ul>\n<li>The <a href=\"https:\/\/humungus.tedunangst.com\/r\/honk\/m\/honk.1\">user manual<\/a> should be required reading so, at the very least, you can grok the honking terminology.<\/li>\n<li>The <a href=\"https:\/\/humungus.tedunangst.com\/r\/honk\/m\/honk.8\">server manual<\/a> shows you some options you can use when starting Honk, explains how to customize Honk&#8217;s (it supports some fun customizations), explains user management, and some additional care and feeding tips. Read this thoroughly.<\/li>\n<li>The <a href=\"https:\/\/humungus.tedunangst.com\/r\/honk\/m\/honk.5\">composition manual<\/a> is a must-read since it shows off all the post composition features.<\/li>\n<li>The <a href=\"https:\/\/humungus.tedunangst.com\/r\/honk\/m\/hfcs.1\">filtering and censorship system manual<\/a> will help you deal with any abuse.<\/li>\n<li>The <a href=\"https:\/\/humungus.tedunangst.com\/r\/honk\/m\/activitypub.7\">ActivityPub manual<\/a> explains what Honk does and does not support in that protocol.<\/li>\n<li>The <a href=\"https:\/\/humungus.tedunangst.com\/r\/honk\/m\/honk.3\">API manual<\/a> has all the information you need to use your Honk instance via some programming language or just <code>curl<\/code>.<\/li>\n<\/ul>\n<h3>Stuff To Try!<\/h3>\n<ul>\n<li>Follow folks on other servers! Hit me up at <code>@hrbrmstr@mastodon.social<\/code> or <code>@bob@honk.hrbrmstr.de<\/code> if you want to test following out (and get a reply).<\/li>\n<li>Customize your site CSS! Make it <em>yours<\/em>. The manuals provide all the information you need to do this.<\/li>\n<li>Add custom emoji and other components (again, the manuals are great).<\/li>\n<li>Write an API wrapper package so you can use your instance programmatically (this is a good way to make an ActivityPub bot).<\/li>\n<li>Look at the <code>toys\/<\/code> subdirectory. It has some fine example programs you can riff from (or just use):\n<ul>\n<li><code>autobonker.go<\/code> &#8211; repeats mentioned posts<\/li>\n<li><code>gettoken.go<\/code> &#8211; obtains an authorization token<\/li>\n<li><code>saytheday.go<\/code> &#8211; posts a new honk that&#8217;s a date based look and say sequence<\/li>\n<li><code>sprayandpray.go<\/code> &#8211; send an activity with no error checking and hope it works<\/li>\n<li><code>youvegothonks.go<\/code> &#8211; polls for new messages<\/li>\n<\/ul>\n<\/li>\n<li>Import your toots or <em>Twitter archive<\/em><\/li>\n<li>Start a Honk instance for one of the communities you&#8217;re in. Honk really cannot support a large community, but small clubs can use Honk vs deal with a full-on Mastodon instance.<\/li>\n<li>Poke around the SQLite databases Honk uses.<\/li>\n<li>Help someone else setup a Honk instance<\/li>\n<li>Customize the Honk codebase and show off your additions<\/li>\n<\/ul>\n<h3>Get Familiar With The Protocols<\/h3>\n<p>WebFinger (mentioned yesterday) is the on-ramp to poking at things, and I prefer playing with instances I own vs annoy folks trying to run &#8220;real&#8221; Mastodon servers.
