Rails cannot connect to mysql server windows 10 - ruby-on-rails

Question

I'm trying desperately to connect my new project / any project at all to the mysql2 server. I'm not really sure whether I've correctly installed MySQL server 5.7.21 or not but perhaps someone could advise.
I'm running ruby 2.3, rails 5.0.7 and mysql2 0.5.1. I definitely have mysql2 in my gemfile. I am running this on my 64-bit laptop with Windows 10
Every time I run a rails db:schema:dump from my project file in the command prompt, it shows this error:
C:\Users\MR_ra\Documents\Sites\matt_radin_cms>rails db:schema:dump --trace
** Invoke db:schema:dump (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:schema:dump
rails aborted!

Tasks: TOP => db:schema:dump
Currently my databases.yml file is looking like this:
default: &default
adapter: mysql2
host: localhost
encoding: utf8
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
username: ***********
password: ***********
My question is also to answer what does the localhost 10061 refer to?

Answer 1

If your databases.yml file only like this which is you shared your question then you update little bit like this
default: &default
adapter: mysql2
host: localhost
encoding: utf8
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
username: xxxxxxxxxxx
password: xxxxxxxxxxx
#=> if live server
#=> socket: /var/run/mysqld/mysqld.sock
#=> for developmen
development:
<<: *default
database: project_development
#=> for test
test:
<<: *default
database: project_test
#=> for production
production:
<<: *default
database: project_production
username: xxxxxxxxxx
password: xxxxxxxxxx
then rails db:create
Actually, that is my configuration which already working
Note: If you developing locally and not set any password for mysql then username and password will look like this
username: root
password:
If you use WAMP or XAMPP you must run this before running rails command. The WAMP is recommended for windows.
that means by default username is root and password is empty.
You can by default set up this configuration if you will run this command for creating a Rails project
rails new project_name -d mysql
