I am getting this ConnectionNotEstablished error whenever I try to access any page on my rails app. The error only started to occur when I installed phpMyAdmin and changed my database's password. I updated my database.yml file to reflect the change but am still getting this error.
Does anyone have more details about what this error is or how I can go about fixing it?
I am running Ubuntu 10.10, Ruby 1.9.2, Rails 3.0.1, and connecting with the mysql2 gem.
Make sure that the database.yml file is properly formed

I ve just recently discovered OctoberCMS. Everything works perfectly on my localhost server. Once i deploy to production server i get the following error:
"Database missing
A database is required to access the back-end. Check the database is configured and migrated before trying again."
I have tried installing from cPanel and have also tried ftp and making sure the .env reflects my production database details, but still getting same error.
Can anyone here plz help? Thanks a lot in advance.
You should check all database accesses in config/database.php file. If the access is correct, try reading the configuration cache with php artisan config:clear.
If this does not help, and the error does not change, it is worth checking the availability of the library responsible for connecting to the base in your php.ini file. In my case, the problem was exactly there (the library was closed)
I had that error after fresh install...After restarting the php server, the error was gone
This is my first MySql install from the ground up.
I am using Windows Server 2016, trying to install MySql 8.0.15. I am doing this to try and use it with php 7.3.1.
The install has all the listed prerequisites.
When I get the config section of mysql insstaller, it breaks on the first response with an error of "Beginning configuration step: Writing configuration file
Invalid server template
Ended configuration step: Writing configuration file"
The system event log has one error, "The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID
{8D8F4F83-3594-4F07-8369-FC3C3CAE4919}
and APPID
{F72671A9-012C-4725-9D2F-2A4D32D65169}
to the user NT AUTHORITY\SYSTEM SID (S-1-5-18) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool."
But I'm not sure this is even the right troubleshooting path to start down.
Can you assist with some guidance?
I had the same problem with the
mysql-installer-web-community.
The mysql-installer-community was working without a problem.
The bottom link is the none web installer which was working.
For me initially when I was not accepting the initial update mysql pop-up then installer was not working, but once I accepted it. Then it successfully worked for me.
I have been able to install after getting the same error.
I have changed the credentials for the sql root.
By default, host is set to something like %ALL_HOST%. I changed to localhost.
I ended up uninstalling all mysql 8 components that had already installed.
Then went back and got the mysql installer 5.7.25.0. I think I had some trouble after that, but it wasn't the same error. I finally ended up installing mysql 8.0.15 by itself and it worked. Then I went back and did the connectors. Next the workbench. Finally docs and samples. Doing them one at a time seemed to go better. I am now up and running.
Here's what I did to fix the issue
completely removed mySQL Server and Workbench installations.
uninstalled the mySQL web installer. Restarted my computer.
ran the mySQL web installer again (only installing mySQL Server)
downloaded the mySQL Workbench installer to install Workbench separately
I am trying to run the command rails server in the folder where is my ruby application but is failing. I am using the followig versions:
Ruby 1.9.3.
Gem 2.0.3.
Rails 4.2.1.
MySQL server 5.5
Someone know how can I fix it?
I just upgraded my Mac to 10.9, Mavericks, and everything went downhill from there. I wish I could easily downgrade and go back. So, after days of troubleshooting, I finally got the rails server to run and I can see my app locally on localhost. But now I am getting a MySQL error (see below) when I try to run the "rails console" command:
/Users/myusername/.rvm/gems/ruby-2.0.0-p481/gems/mysql2-0.3.16/lib/mysql2/mysql2.bundle: [BUG] Segmentation fault
ruby 2.0.0p481 (2014-05-08 revision 45883) [x86_64-darwin13.1.0]
Any advice / help on this one would be appreciated. Thanks in advance!
So I was making some tests here on Rails and for first time I decide to use MySQL, I've setting up the gem mysql2 and the mysql server.
When I try to access the database I receive this:
ActiveRecord::ConnectionNotEstablished
The strange thing is I'm able to run the rake db:create and the migrations without any problems.
thanks in advance,
Renan
ActiveRecord::ConnectionNotEstablished
Raised when connection to the database could not been established (for example when connection= is given a nil object).
Try checking your db configurations in the config/database.yml file if everything is correct or not!!
