Capistrano deploy error while deploying to Ubuntu server

Capistrano deploy error while deploying to Ubuntu server - ruby-on-rails

I was following this blog, to set up my rails server, and after I ran this command, I am getting the following error

Tasks: TOP => rvm:hook

So in my deploy.rb file which is generated by Capistrano, I commented out
this line. And it started to work.
set :ssh_options,{ forward_agent: true, user: fetch(:user), keys: %w(~/.ssh/id_rsa.pub) }

It appears Capistrano can't connect to the server and is timing out, the most likely culprit is that it's not reading the SSH key correctly. The easiest way to test it would be to try creating an ssh config file:
nano ~/.ssh/config
Add:
Host 104.197.138.17
HostName 104.197.138.17
IdentityFile ~/.ssh/id_rsa
Try:
ssh deploy#104.197.138.17
Make sure it connects. (I'm assuming 104.197.138.17 is the IP of your server...)
If that works, try cap production deploy:check again.
--
What's happening here is the ssh config will feed the extra parameters to any SSH call to that Host (in this case the IP). You could change the Host to 'mysite.com' if you wanted and then you would run ssh deploy#mysite.com if you wanted to create some separation. Digital Ocean has tutorial about it.

How do I find what port my rails server is running on and how do I change it?

I'm new to coding and working on a team project where I've just set up rspec from a Github repository and I can't seem to set up my server. I've run db migrate and db drop to see if there were any errors there as seen below. The rails s command is starting the server but it isn't able to connect on localhost:3000
rails db:drop

If anyone could help or give me some pointers, I'd really appreciate it. I am just learning so I would really appreciate help in layman's terms if possible. It will mean the world.

You can find process ID with this
#=> ps aux | grep rails
#=> username 27436 0.0 0.0 408497296 1424 s002 R+ 6:01pm 0:00.00 grep .... rails
Then use to process ID(ID next to username) to find the port it is running on
#=> ps -p 25785 -o comm=
#=> puma 5.5.2 (tcp://localhost:3000) [MyRailsApp]

Cap deploy failing on precompile assets but cap <env> deploy:precompile:assets works

I removed and then re-added a few files to github so that the gitignore would work, and then uploaded these files through capistrano to server.
Then started having some deploy trouble failing on precompile:assets.
I was able to find the issue, fix and now cap env deploy:precompile:assets gives me all green. But when I run cap env deploy I am still getting:

Tasks: TOP => deploy:assets:precompile
The deploy has failed with an error: Exception while executing as deploy#staging.myapp.com: Connection reset by peer - recvfrom(2)
** Invoke deploy:failed (first_time)

Unsure how to troubleshoot since the task seems to work, and I can definitely connect to the server (uploaded files through cap etc...)
Thanks for any tips

Psych::BadAlias: Unknown alias: 1 when running rake jobs:work

Something strange is happening with my application when I boot the jobs server with rake jobs:work. The rails webserver boots fine. I've noticed threads such as this one, however 1) it's not quite the same error message, that one seems more straightforward and 2) the answer did not yield any different results.
Here's my stacktrace -

I got the same issue after ruby upgrade from 2.1.5 to 2.3.8. Thats latest ruby version that could be run with rails 4.1.8.
Upgrading to the latest version of delayed_job did not help. Also tried to specify downgraded version of psych gem in my Gemfile. This did work not as well.
The real issue is that if error appears on job parsing stage then delayed_job does not update last_error column.
So I just went though all the jobs and checked if it could be parsed or not:
failing_jobs = []
Delayed::Job.find_each do |job|
begin
# this code is from dj source https://github.com/collectiveidea/delayed_job/blob/master/lib/delayed/psych_ext.rb#L15
yaml = job.handler
result = Psych.parse(yaml)
result ? Delayed::PsychExt::ToRuby.create.accept(result) : result
rescue Psych::BadAlias => e
failing_jobs << job
end
end
In my case it were 6 jobs out of ~3k that could be deleted safely so I got lucky :)

Rails throwing a Redis::TimeoutError

I have tried twice to install an installation of RubyMine on a CentOS7 VM. They have now both failed due to a Redis::TimeoutError.
I have received this error when attempting to start the rails server. This happens both through RubyMine and through the Konsole after I start redis through the "service redis start" command.
I can start the rails server fine without starting redis first. And the application works fine (so far) if I start redis after the server starts. However this is only a short term solution as I will be adding automatic start for all services such as redis when my VM starts.

I hava a same problem when I create redis-cluster.Finally,I find the problem.

1、gem uninstall redis
2、gem install redis --version 3.0.0

Ruby messes up when trying to do rake db:create with postgresql

I have just installed postgresql, because I want to put my apps onto heroku. When trying to set up a new rails app using pq, once I rake db:create and I get the following error message, I have no clue what it means, or what to do.
Here's the error message that I'm receiving.
new-host-2:scheduleScraper rickmasta$ rake db:create:all
could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"?

Couldn't create database for {"adapter"=>"postgresql", "encoding"=>"unicode", "database"=>"scheduleScraper_production", "pool"=>5, "username"=>"scheduleScraper", "password"=>nil}

This is a known issue when installing PostgreSQL with brew on Mountain Lion. Postgres is putting the socket file in a different directory, /var/pgsql_socket_alt, then where psql, createdb, Rails, etc. know where to look for it. You need to change where the socket file goes via the postgres.conf file. See this link on how to fix it.

You may have installed postgres, but is it running?
I got almost identical errors after a reboot of my machine, because I didn't remember to (re)launch the postgres application locally. After I launched the PostGres application again, everything worked without a problem.
These were my errors:
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 5432?
could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5432?
could not connect to server: Connection refused
Is the server running on host "localhost" (fe80::1) and accepting
TCP/IP connections on port 5432?
