Capistrano setup on MacOS Mojave

[Miroslav Schlossberg]

Hi everyone,

I'm trying to setup Capistrano but always hit a blocker.

I have followed steps at https://alaveteli.org/docs/installing/deploy/

To install Ruby on MacOS Mojave I have followed steps here:

https://gorails.com/setup/osx/10.14-mojave 

Ruby 2.6.3 was installed as recommended in the gorails guide:

Installed ruby-2.6.3 to /Users/miroslav/.rbenv/versions/2.6.3

I've also installed rbenv, so Ruby versions are managed via rbenv. 

When I execute step "still on your local machine, run cap -S stage=staging deploy:setup to setup capistrano on the server" I get following error:

(base) Mac:alaveteli miroslav$ cap -S stage=staging deploy:setup

invalid option: -S

Did anybody had similar issues on MacOS? 

Cheers,

Miroslav

You need to use the capistrano version provided by Alaveteli, so run `bundle exec cap…`

Best,

Hi Gareth,

Thanks! I've opened GH issue as it seems that deploy guide is not mentioning part that it should be run via bundle exec.

I've hit another problem:

(base) Mac:alaveteli miroslav$ bundle exec cap -S stage=staging deploy:setup

Could not find rake-12.0.0 in any of the sources

Run `bundle install` to install missing gems.

So I've tried to do bundle install:

https://github.com/brianmario/charlock_holmes/issues/117 (different setup has issue with different charlock_holmes version)

I have tried and 0.7.6 can be installed.

Is it safe that I update this gem version from 0.7.5 to 0.7.6?

If yes, what is the safest way to do it? Just by updating Gemfile (or Gemfile.lock)?

Also I see it should be using version 0.7.0: https://github.com/mysociety/alaveteli/blob/release/0.30.0.0/Gemfile#L90

Here is version 0.7.5: https://github.com/mysociety/alaveteli/blob/release/0.30.0.0/Gemfile.lock#L108

(I'm installing version 0.30.0.0)

Thanks!

Cheers,

Miroslav

Hey Miroslav,

I have tried and 0.7.6 can be installed.

We use 0.7.6 in the latest release of Alaveteli https://github.com/mysociety/alaveteli/blob/master/Gemfile.lock#L114

Is it safe that I update this gem version from 0.7.5 to 0.7.6?

Patch releases are generally a safe bet, yeah.

If yes, what is the safest way to do it? Just by updating Gemfile (or Gemfile.lock)?

You can run `bundle update charlock_holmes`. This will install the new version and update Gemfile.lock for you.

Also I see it should be using version 0.7.0: https://github.com/mysociety/alaveteli/blob/release/0.30.0.0/Gemfile#L90

The ~> actually means "the latest patch release of 0.7.0" – Bit more detail here https://guides.rubygems.org/patterns/#pessimistic-version-constraint

I've also made a pull request to clarify the deployment docs, based on the issue you raised at https://github.com/mysociety/alaveteli/issues/5386. You could ignore needing to bundle and just install the older version of capistrano (as per https://github.com/mysociety/alaveteli/pull/5387/commits/b90efa4a6c6034f9e9c966106ee8a576098439b0) to avoid needing to install all the dependencies on your Mac. If you're going to use your Mac install for development, then might be worth getting it running, if not, then just try `gem install capistrano -v 2.15.9`.

To install charlock_holmes 0.7.5 you'll need to install an older version of icu4c - version 53.x [1]

On macOS if you're using homebrew [2] this can be install this with:

$ brew install icu4c@53

And then install the gem with:

$ gem install charlock_holmes -v '0.7.5' -- --with-icu-dir=/usr/local/opt/icu4c@53

Next time you bundle the gem should be found.

Hi Gareth and Graeme,

Thank you guys, that helped. I had few more unresolved gems, but I don't need them as I won't be doing development on this computer.

Now, I've setup login via ssh key for deploy user as per capistrano guidelines, and I can login from terminal as usual "ssh deploy@ip". But, after setting up alaveteli capistrano config/deploy.yml and executing "cap -S stage=production deploy:setup" (again - guidelines does not say this specifically, but I assume if I don't want to deploy staging config but production, I should use "stage=production", correct?), I'm getting following error:

(base) Mac:alaveteli miroslav$ bundle exec cap -S stage=production deploy:setup

  * executing "cat /var/www/imamopravoznati.org/alaveteli/shared/rbenv-version 2>/dev/null || true"

connection failed for: xxx.xxx.xxx.xxx (NoMethodError: undefined method `p=' for #<OpenSSL::PKey::DH:0x00007fcc55038a58>

Did you mean?  p)

From earlier bundle install, I see that required gem net-ssh is 2.9.4 which is as per above.

Tried with newer net-ssh but it will insist specifically to use 2.9.4:

(base) Mac:alaveteli miroslav$ bundle exec cap -S stage=production deploy:setup

Could not find net-ssh-2.9.4 in any of the sources

Run `bundle install` to install missing gems.

Cheers,

Miroslav

Hi guys,

When making deploy update (initial, as per instructions), I got some lines with "err :: IP" - is this expected or some error?

How to troubleshoot this?

Example of err deployment output in terminal:

*** [err :: xxx.xxx.xxx.xxx] I, [2019-10-02T19:02:45.040221 #88422]  INFO -- : Writing /var/www/imamopravoznati.org/alaveteli/releases/20191002185052/public/assets/favicon-3e06c6d6cb34168fb0342ef3186f733b2c7d1c44422d1136013ad3cca6c4694f.ico

and on last line:

 ** transaction: commit

  * 2019-10-02 21:07:29 executing `deploy:restart'

  * executing "/etc/init.d/alaveteli restart"

    servers: ["xxx.xxx.xxx.xxx"]

    [xxx.xxx.xxx.xxx] executing command

*** [err :: xxx.xxx.xxx.xxx] su: must be run from a terminal

    command finished in 77ms

failed: "sh -c '/etc/init.d/alaveteli restart'" on xxx.xxx.xxx.xxx

Full terminal output: https://etherpad.net/p/IPZ-v2-cap-deploy-err

So it looks app cant be started. Also tried grepping ps aux for 3000 and nothing is up.

Cheers,

Miroslav

Looks like the permissions aren't allowing you to restart via the init.d service.

The `user` in your `config/deploy.yml` will need to have +x permissions on `/etc/init.d/alaveteli`.

In our manual install guide, we recommend they get set to 754 [1].

This allows users in the `alaveteli` group to execute the file (which is owned by root).

Does that look like the setup you've got?
