Cannot connect to local database - mysql

I have apache and mysql set up on my local machine (Mac).
Whenever I go to any of my local sites I get the "Error establishing a database connection" whenever anything mySql related happens.
It was working perfectly yesterday, but when I started my computer today it is not.
I can login to mysql on the terminal and that all works fine, I can view database and run queries in the terminal. Look at all my table etc.
I've tried restarting apache.
Anyone know what's up? This is worrying.
UPDATE...
It is somthing in my php.ini file, if I restore the default one it all works fine and dandy again. What in there could be doing it?

The problem was in php.ini, I needed to set:
mysql.default_socket = /path_to_file/mysql.sock

I know this isn't an answer to the specific question, but it is rather a suggesting IF you are just doing development on your box. I would suggest skipping all the configurations and go with MAMP

Easiest way to have a MySql database to make some queries against a dump file

I have a dump file of a MySql Database (I never worked with MySql, but I am assuming it's similar enough to SQL Server), because I don't want to run my queries in production.
I never created a local environment and I never worked with MySql. I tried to download MySql Workbench, but the GUI is not helping me. In SQL Server I would just connect with localhost and then everything would be fine. It was back then I had a managed PC by my previous organization. I suppose they installed everything to me.
I want to set up it and just go away. It could be in the cloud or locally.

Local wordpress issues: Mac MAMP

I'm having some issues with my local environment. I had setup a wordpress site locally on my Mac through MAMP. All was working well until my computer powered down (not plugged into power source). Now there appears to be issues with the database. When i run MAMP and try to connect I get the error "Error establishing Database Connection". Also when i go through the MAMP portal at localhost and click on Tools > PHPMyAdmin I get the following error:
MySQL said: Documentation
#2002 - No such file or directory — The server is not responding (or the local server's socket is not correctly configured).
mysqli_real_connect(): (HY000/2002): No such file or directory
Obviously something has gone very wrong with the database connection but do not know how to resolve. I have tried to run some scripts in terminal to stop mysql process to no avail so far.
Any advise appreciated. I have looked at some similar but not exact other posts and does not seem to resolve.
Note: The ports changed at some point in the process, but everything else seems fine related to the new port setup but this may be relevant
thanks
While, I'm not sure of the cause. FINALLY found a solution to this very frustrating issue.
What ended up working for me is to uninstall the new version 4.2.1
I did this through first going to the MAMP PRO folder and using the MAMP Pro uninstaller and then moving the Mamp and Mamp pro folder to the trash.
I then went and found the old version to install
https://www.mamp.info/en/downloads/older-versions/
When I downloaded 3.5.2 whatever issues it was having with local databases were resolved. Go figure! Glad to finally have resolved not sure why this would happen other than perhaps a bug in the new version.
Thanks to those who pointed out some possible things to look at
I'm running MAMP 4.0.6 and getting the same error on local wordpress installations, and same error message as described when trying to go to phpmyadmin on MAMP.
The reason seemed to be that the mysql server does not start. The solution that worked for me is offered in this reply in another thread:
https://stackoverflow.com/a/45582509/4623519
Quit MAMP. In the finder go to Applications/MAMP/db/mysql/. Delete the last log file (look for a file named ib_logfileN – being N the log number Eg-ib_logfile0 and ib_logfile1) Nice screenshot provided in link above.
This seems to be happening often according to this post from 2013.

Xampp mysql cant run database i already created

i installed xampp and planing to use the apache server and the mysql server.
while running the first time, i load the database from phpmyadmin, and it loads fine. after i work with my app i check that the db is updated and it is.
after closing the servers and returning to them later, i have problem to start the mysql server, so i found some helpfull links and followed them...
XAMPP - MySQL shutdown unexpectedly
although it did helped but im not sure the issue is the port. what worked for me is deleting the ibdata1 file.
so why cant i run the mysql the second time? each time i have to delete the file?
following question one, i have problems updating my databases in phpmyadmin, and have to delete the db manually from c:\xampp\mysql\data\"db_name"
and then loading it again through phpmyadmin. im sure this is the wrong way but not deleting it will mess up the db so dont have any other choice at the moment.
please note there are 2 separate questions, but the issue is the same.
thanks

How to to fix XAMPP after deleting too many MySQL databases?

I've been stupid enough to delete too many databases in XAMPP with PHPMyAdmin and now my sites on localhost don't run properly anymore. Please see this screenshot of the main errors
I guess entirely reinstalling XAMPP will fix the problem but that might take much more time than necessary. Preferably, I'd like to just reinstall the MySQL component or perhaps recreate/repair some databases required for XAMPP to function properly. However, it looks as if I can only reinstall XAMPP entirely instead of separate components (and if that's correct, it's probably for a reason...).
Do I have a better option here than a complete reinstall of XAMPP?
OK, fixed it with the kind help of scones.
1) By default (XAMPP 1.8.1 on Windows XP), there seems to be a folder C:\xampp\mysql\backup\phpmyadmin. Just copy-paste this entire folder into C:\xampp\mysql\data.
2) Stop and restart MySQL
3) If you're using WordPress, your pages may be blank since it may think there are no themes available. Go to [frontpage url]/wp-admin/. Now just reactivate the theme you'd like to use and all seems up and running again!
You dropped the database for PHPMyAdmin. If you can just restore that (with a command line mysql tool or any tool that does not rely on a web-interface), you can use phpmyadmin again.

MySQL not connecting with PHP

I installed MySQL server and everything worked fine in command line. I worked connecting MySQL to my ASP.NET application and there is no problem at all. But when I try to connect MySQL to PHP applications I am unable to connect. When I installed PHPMyAdmin I am getting error #2002 Connot log in to thie MySQL server
I browsed all the night for this error and none of Google's results helped me! :(
Anybody can you please tell me where the problem is at? I believe I must change my PHP.ini file settings in order to connect to MySQL. Anybody please help me.
There are a lot of things that can cause this type of issue. Did you make sure that you have added php-mysql drivers to your sever. Since you said your using ASP i will assume that you are using windows servers. Make sure that you also are allowing that user to connect via localhost or what ever ip the PHP is on.
In php there are to standered ways of connecting to a MySQL database.
php-mysql(is going to be depercated soon).
php-mysqli(OOP version of the php-mysql with lots of features).
With out one of these php will be unable to work with a MySQL database. I am not sure if phpmyadmin works with both drivers or just one of them It could be throwing a die("message") Just to let you know it is not working instead of throwing a more complex php error. You may want to see if you can incress error reporting.
You can check if your php installastion has the mysql driver by looking in your php.ini and also checking with.
phpinfo();
It is almost always about config. https://bbs.archlinux.org/viewtopic.php?id=90133
