Here begins the chronicle of my flailing around trying to set up metasmoke on Thomas Ward's graciously-donated server space...

This'll be part documentation, part humor, part mockery of my past self

1. Setting up MariaDB

Old server version: mysql Ver 15.1 Distrib 10.3.12-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2

New one:

mysql Ver 15.1 Distrib 10.1.43-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2

Looks compatible

Running the backup script on old SQL instance to get a new DB copy

(Will do this again right before cutover)

Making a new DB user for metasmoke in Maria

... and looking up the syntax like I do EVERY TIME

MariaDB user is metasmoke/metasmoke

because why not

Importing new DB

(just mysql < file.sql)

Installing RVM, the best thing since sliced bread

... maybe excluding cinnamon rolls

We're currently on Ruby 2.5.0, gonna keep that for now

lol somehow no binary rubies found

so it's gonna compile it

(which is fine, just takes a minute or so longer)

okay so that didn't work; I guess we're going to 2.5.7

(which has a binary ruby available)

and done

also my laptop is at 70% and I left my charger at home

so it's a race against the clock

SUSPENSE!

aaaaand now I forgot what comes next

oh cap deployments

okay now the fun part

Gonna just write out all the error messages and all the fixes

SSHKit::Runner::ExecuteError: Exception while executing as [email protected]: ruby exit status: 2
ruby stdout: Nothing written
ruby stderr: Gemset 'metasmoke' does not exist, 'rvm ruby-2.5.7 do rvm gemset create metasmoke' first, or append '--create'.

(Do what it says, rvm ruby-2.5.7 do rvm gemset create metasmoke)

Cap does the initial git clone

complains because (of course) config files don't exist yet

but it creates the whole dir structure

00:03 deploy:check:make_linked_dirs
      01 mkdir -p /var/railsapps/metasmoke/shared/config
    ✔ 01 [email protected] 0.397s

^ Looks like that

Capistrano got to bundle install

And threw the ye-olden error I hit every. single. time

An error occurred while installing mysql2 (0.5.2), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.5.2' --source 'https://rubygems.org/'`
succeeds before bundling.

HAH

SOMEONE FORGOT THEIR SUDO PASSWORD ALREADY

... oh

wrong machine

that's why

okay it works

if you use the right terminal

So it's just sudo apt install libmysqlclient-dev for that

 DEBUG [fe7572a1] 	rake aborted!

ExecJS::RuntimeUnavailable: Could not find a JavaScript runtime. See github.com/rails/execjs for a list of available runtimes.

Should just be sudo apt install nodejs for that one

Thomas Ward

@Undo go to latest node

don't use straight sudo

otherwise it installs 0.10.2 (old)

want me to install up-to-date nodejs?

Undo

Sure

Thomas Ward

1 moment

I feel like I've gone down this road and latest broke something, but probably wrong

Or was a long time ago and they've fixed it

Thomas Ward

sudo apt-get install curl
curl -sL deb.nodesource.com/setup_13.x | sudo -E bash -
sudo apt-get install nodejs build-essential

nodejs 13 should be installed now see if it works @Undo

if not i'll uninstall and we can put to the old one :)

Sweet, trying it now

Seems okayish so far

Thomas Ward

noms cake and stands by for breakages

Undo

Hitting github.com/rails/webpacker/issues/2156

which is new for me

Thomas Ward

workarounds dictate yarn upgrade give me a second to install yarn

Undo

Already there

Got a weird reproducibility issue

Thomas Ward

o.O

Happens in Cap, not when running manually

okay actually I have to set up redis first

otherwise it's irritating

Thomas Ward

(Heh) (Possible issue related to github.com/terser/terser/issues/380#issuecomment-507067182 and github.com/webpack-contrib/terser-webpack-plugin/pull/103 according to linked issue)

@thesecretmaster Do you have a Redis setup guide somewhere? Moving servers, need to know how to get it working w/ custom additions and such.

Basically blocked on that for now
