Error establishing a database connection. How to fix it?

Support
1

Hi Everyone,

I’ve been using Local for a while now, I had created my entire website on it and I was going to launch it soon but I’ve now been getting this error when I try to view it:

Error establishing a database connection

This either means that the username and password information in your wp-config.php file is incorrect or we can’t contact the database server at localhost . This could mean your host’s database server is down.

  • Are you sure you have the correct username and password?
  • Are you sure you have typed the correct hostname?
  • Are you sure the database server is running?

I know it’s been talked about it on here, but I don’t know how to fix it. The wp-content.php doesn’t seem to have any problems. I tried to upload the zip folder of my website on local but it says that it cannot upload the sql file. I cannot log in Adminer because it says that the credentials are wrong. when I stop the site, I get this:

Error: Error: mysqldump exited with non-zero exit code.
at SiteDatabaseService. (/Applications/Local.app/Contents/Resources/app.asar/main/sites/database/SiteDatabaseService.js:1:5584)

at processTicksAndRejections (internal/process/task_queues.js:85:5)

What should I do?

Thanks a lot,

Daniele

Hello Daniele,
I hope you found a solution for your issue. I find mine but it far from resolving the issue:
I imported an “export” of the site I made few days back and use the typed the password myself to be sure that it was the right one, and it worked

How the problem happened :
-My mac shut down unexpectedly
-When i restarted it, and local, it asked me for my Wordpress Login & Password
-I put the password registered by my google account
–> and then had the issue to not be able to access my website with local

    Uh-oh! Local ran into an issue while exporting this site's database to the site's 'app/sql' directory.
Error: Error: mysqldump exited with non-zero exit code.
    at SiteDatabaseService.<anonymous> (/Applications/Local.app/Contents/Resources/app.asar/main/sites/database/SiteDatabaseService.js:1:5570)
    at Generator.next (<anonymous>)
    at _0x234e99 (/Applications/Local.app/Contents/Resources/app.asar/main/sites/database/SiteDatabaseService.js:1:2163)
    at runMicrotasks (<anonymous>)
    at processTicksAndRejections (internal/process/task_queues.js:85:5)

I’ll keep looking to find a way to resolve this for the site that is in error.

Good luck !

I have the same MySQL non-zero exit message when closing my sites also. Local continues to open and seems to work properly except for closing. I switched off AV, reinstalled, checked codes. Did you ever find an answer? Did it adversely effect anything?
