I keep running into this error each time I run the command rails s. I have had issues with installing gems, and running bundle from this directory. All I want to do is run my server on the designated port. I think I might not have the right credentials to run the server locally. The top level error I got is telling me that the MySQL server is not connecting. I have looked through a few other StackOverFlow threads and none of them have seem to help me. I have a Linux box, running Ubuntu 14.04. Please Help.

  • Looks like this might involve [the infamous "mysql.sock" error](http://stackoverflow.com/q/5499035/1167750)... (from looking at this line: `Can't connect to local MySQL server through socket > '/tmp/mysql.sock' (2) (Mysql2::Error)`) – summea Jun 24 '15 at 02:54

    Went through that thread no dice. Might have done it wrong check out my config file above. – sanoy Jun 24 '15 at 04:02
  • Hmm, and you're sure that MySQL is up and running, and that your `mysql.sock` path is correct in your config file? – summea Jun 24 '15 at 04:56

Rails is trying to connect to a MySQL database. Do you have it installed on your Linux server? What does your config/database.yml look like?

Check out Digital Ocean's guide on Installing Rails, Apache, and MySQL on Ubuntu.

  • Config file is up. I have a Linux box and I'm running Ubuntu 14.04. I'm just looking to get a local server up so I start developing locally. – sanoy Jun 24 '15 at 04:02

Got it! I had to Purge Mysql, and then re Install it. 

sudo apt-get remove --purge mysql-server mysql-client mysql-common

sudo apt-get autoremove

sudo apt-get autoclean

Then I used the doc below to re install it. (Link below)

Follow console steps very closely

When running this command:

sudo mysql_secure_installation

Once you run this command you will be promoted to a few messages on your console, run the yes command when the console asks you if you want to set permissions now.
