Default Database name in wordpress - wordpress

badly need help here. I have a website hosted in wordpress.com. I played around with the wp-config.php file and changed this line.
define('DB_NAME', 'mydatabase');
I have uploaded this and now everytime I load my website it says "Error establishing a database connection". I was not able to remember the database name, is there a default database name for wordpress? Note that my website is not local, it's already online. (http://european-supplement-shop.com/)

ALl you have to do is to get the name of the database from the control panel of your hosting and if its not set then give a name to the database and then change the name in wp-config.php

When installing a new version of Wordpress, the database is usually automatically given the suffix wp_ and then a series of numbers. This is an arbitrary number, so won't actually have any relation to anything in your install.
If you don't have access to your host's control panel, you will need to contact them to find the database name. Make sure you have some way of identifying yourself as the owner of the domain before calling as they will need to verify you are who you say you are before providing this information.

There isn't a default database name for WordPress. WordPress provides the files, where as you (or your host) provides the database. If you didn't create the database yourself, then contact your hosting company to find out the database name.

As both Ronan and hery point out there is no default name for WordPress-databases.
However, looking at your hosting provider's website, it seems that you can only find the db name by logging in here:

(I know you say that you don't have a login but I sense by the comments that it might be lost in translation).
I base my answer on this.

phpadmin password change - creates error establishing database connection on wordpress

I have created a wordpress VM in GCP and all works perfectly. After the creation it is recommended that you change the temp passwords (makes sense). When I change the temp password on phpmyadmin the wordpress vm loses it's host. When i change the password back again to the original temp password the wordpress site comes back up again.
So I assume there is a connection between myphpadmin credentials and the wordpress host but I don't know where this relationship resides in the database and how to change both sets of credentials so that i can change the phpmyadmin password and maintain the connection to the wordpress site.
Happy to provide more info - im actually sure this is a very basic issue but struggling to find articles to help.
Cheers
The credentials you enter in phpmyadmin is actually not to access phpmyadmin itself, but rather for phpmyadmin to access the database. Then, the phpmyadmin is pointed to the same database as your wordpress site, so if use the same credentials for both and you change said credentials, you need to specify the new ones for both the phpmyadmin and wordpress.
This is not specific to GCP.
I just wanted to update my own question in case someone else is a new as me. I am also sure there are more efficient ways to achieve the answer but this is how I did it.
My struggle was that I did not know how to access wp.config.php file which contained the password of my wordpress data base. So I was changing myphpadmin password and then losing the data base as the credentials were different. Then I was at a loss as to how to actually change the wp.config file to match the new password.
To do this I did a number of steps. I will also add helpful links to resources below.
I installed an FTP client and established a connection with my google cloud vm.
I located the wp.config file, in my case this was /var/www/html
I exported the file and updated the password to match myphpadmin password.
I re-imported but as I didn't have permissions to re-import to the same location (never did figure this out) I re-imported to the user folder found /home/
I then went back to my googlecloud console, SSH in and as the root user moved the file from the folder I re-imported to the correct folder as mentioned above (/var/www/html). This then overwrote the existing file and updated my password.

Wordpress wants to install itself, rather than run the blog

We have created a duplicate of our website on a new server as part of a migration. We have a wordpress blog that is part of our website.
The docroot of the wordpress site is set as an alias in our main site. The result is that to access the site home page, the following url is used: https://www.rephunter.net/blog/.
The new environment is not available to the public at this time, and is only accessible within our VPN. When the above link to the blog is followed, instead of the expected home page of our blog, we get the page at https://www.rephunter.net/blog/wp-admin/install.php, which wants to install a new site.
The configuration in the new environment is supposedly an exact copy of our production site from some time back. The permissions on the main files is the same.
What is it that is causing the attempted blog access to be redirected to the installation script?
EDIT:
The responses so far have not really absorbed the intent of the previous information. We are not migrating in the normal sense. Rather we are testing in a new virtual environment that will eventually lead to a more normal migration.
We have an exact duplicate of our original wordpress and database environment that is running in a virtual environment with an updated protocol stack that is only accessible if you are on the VPN for that environment. As far as we can tell, there is no difference in the configuration.
For example, the parameters in wp-config.php are exactly the same as in the original installation. When php runs, it sees the same environment, with host names and everything identical. It would not work otherwise.
Yet if there really were no difference, it would just run. But since WP is trying to install a new database, there is something different that we are missing.
To further illustrate this: supposed you took an image backup of the wordpress installation and the database, and put it in a different VM, and set up the DNS and everything as it needs to be--the new environment looks no different than the old one. All databases, wp-config settings, etc, are the same. So our main website and database functions very similarly.
As I mentioned above, the difference in the protocol stack should be considered. The old system is on PHP 5.6.27--the new one is on 7.3.4. So that could be causing some difference, which maybe somebody might recognize. Wordpress is 5.2.2 and should be compatible with both PHP levels.
We believe there is some relatively simple parameter setting that we are missing. For example, as in the first answer that $table_prefix is set wrongly. But that is not it in this case.
WordPress redirects you to that installation screen because the database it's connecting to is working (meaning, the username and password are correct), but the data it's expecting to be there isn't. Therefore, it assumes it's a new / empty database and prompts you to install WordPress.
I've seen this happen in two scenarios:
The database really is empty, and thus WP needs to install the standard tables and info
The table prefix in your wp-config.php file is incorrect for an existing database
Look at your wp-config.php file in the root directory of WordPress, and look for a line similar to this:
$table_prefix = 'wp_';
Then, open up the database (phpMyAdmin or some other interface to browse what the database structure actually is) and confirm that the table prefixes (the first few characters of the table names) actually match what's set above.
Hopefully this gives you something to go on! Let us know what you find
Migrating Wordpress websites can be quite tricky. I've worked as a WP developer for a number of years and always struggled with manually migrating websites.
There are a number of factors to consider:
WP stores a lot of installation specific information within the database. So you can't do a database dump and upload the export into a new database.
Changing the website url within the wp_options table in the databased there are still other references to the original url scattered throughout the db.
You could try a find and replace all using an editor that supports this sort of functionality (vscode, sublime, atom) but things always end up breaking and your doing tons of "find & replace" actions.
I have always relied on a 3rd party tool Backup Buddy as it simplifies the entire backup and migration process and offers the peace of mind of having easily deployable backups for your website.
Backup Buddy allows you to export your website as a zip and then you can move the zip to any server you want and the plugin provides an installer script (php) to guide you through the migration of your wp site to any host and database of your choosing.
Note: I am not in any way affiliated with iThemes or Backup buddy, and I do not stand to benefit in anyway if you decide to use the plugin. This is only advice on a tool that I have found helpful, reliable, have had success with, and currently actively use on a number of websites that I maintain.
WordPress display installation page because you have not update your wp-config.php file after migrating server so please follow below steps in future when you migrate your website.
Please follow this steps when you migrate your WordPress website from one server to another server.
Back up your website files/database
Export wordpress database.
Create database on your new host server.
Edit the wp-config.php File and edit this details.
Add new database name
Add new database username
Add new database user Password
Add new host as per your hosting provider or (localhost is default)
Import your database to new server.
upload the WordPress files to your new host
defining new domain URL & Search/Replace old domain URL

Wordpress migration - Admin panel Issues

I wanted an exact replica of my current wordpress website on a different domain with a different database.
So I created a database in same db host as the original database.I changed siteurl and homeurl in new database to the corresponding new domain.
I dumped the same code to new IP and changed wp_config file i.e. dbname,dbuser and wp_home wp_siteurl.
I kept db_host same as I have both the databases on same host.
I was able to get the replica up on new domain,but I am facing following issue -
whenever I change my password for admin in new admin panel , it gets reflected in my original website database and vice a versa.
Similar thing is happening for advanced custom fields in my admin panels.If I change something in new admin panel,it is reflected on my original website.
What could be the issue?? I think I have followed all the guidelines of wordpress migration to other domain.
Thanks in advance :)
You need to change the domain name in database then only it will solve the redirection issue.
If you have updated database details in wp-config.php file, there is no chance for the issue. First please confirm that both wp-config.php files have different database details like database name, user name & password.
For WordPress database migration between different domains, either use wp-cli command, or some other database migration plugin. An updating wp_home & wp_siteurl in DB is not enough.

Website keeps going to http://MyWebsite.com/wp-admin/setup-config.php

My website keeps going Website keeps going to http://MyWebsite.com/wp-admin/setup-config.php. Can you help? Thank you
If WordPress can't find the tables in the database, it will be redirected to the setup process. This usually occur when you transfer the website to another host and the prefix is different. Check your wp-config.php for the table prefix to see if it matches what's on the database.
.htaccess doesn't have anything to do with this. If your site was running before and you're suddenly gettting the Install screen, your database details in wp-config.php have changed, such as the database name and/or table prefix. Check those. You are connecting to the database, as you're not getting a database error. But your table prefix or database name was changed.

What step have i missed? Transferring wordpress site

So i have recently tried to transfer my wordpress site to another server.
I have followed a few guides, but i definately seem to be missing a step.
Basically what i have done is:
export original database (phpMyAdmin)
Save all relevant files (ftp)
install fresh wordpress on new server. (wp backend)
'drop' all table fields in new wordpress (phpMyAdmin)
import original database to new location (phpMyAdmin)
transfer theme, plugins, uploads. (ftp)
activate theme, plugins. (wp backend)
update permalinks. (wp backend)
The problem is, i am left with a default looking wordpress installation, and not my orginal page-home.php and corresponding css.
Also, if i go to wordpress backend SETTINGS > READING > Frontpage:static; i only have the option of 'about', not home, i should have 'home'...
Sorry if i am vague, let me know if any screenshots are required.
We really need a little more info like:
when you say plain, do you mean just the theme is not set and you're on the default theme, or there is no theme, or do you mean even your content is not there?
the site you removed it from, where was the installation located? Was is in the public_html folder or a subfolder of that? Did you put it in the same place, ie not inadvertently put it in a different folder
(I've actually typed the bulk of the post and come back to the top for this one, but):
Are you sure you're checking the right site?
Have you kept the same domain name?
Has the domain name propagated to the new server?
Is the CSS being loaded from the correct domain (has anything been hardcoded to the old server)
Let's go through a few broader options:
1. Check how many WordPress installs are on your domain
First off, it sounds like you may have two WordPress installations. If you have the backend setup correctly with your themes but you're seeing a plain site, it sounds like you're looking at another install. I'm not saying you do have multiple installs, but it is a place to start looking.
A question to ask yourself here is: In this plain looking site, do you see your content, or the content of a default site? If you see your content, you may jump ahead to section 2.
If you're saying there is a home page but you're not seeing it as available under static pages, either:
You're looking at another site (but there should be a home page* even in a default setup—from memory), or
You're Home Page title may have changed, or have become "unpublished", ie reverted to a draft, or pending review. Check the page:
actually exists,
has the title you're looking for
the slug hasn't changed
(*note: although it could be a Welcome Page I'm thinking of here.)
Double check the database
The easiest way to do this is to go into your database and see how many WP databases there are. Check each database and look for the underlying table structure, it sounds like you should be able to identify it pretty easily. If it's not a multisite install, the table prefixes should be wp_ unless you changed them somewhere.
While you're playing around in the database, Take note of the database name and table prefix.
Double check the folder structure
Have a look for a second instance of your folder structure, maybe you dropped it into the wrong place).
2. Check the WordPress installation is actually connected to the database
Check the WordPress configuration file wp-config.php is connected to the database. Check wp-config.php sample from codex, you'll want to see the correct database name and table prefix in there.
From here you should also check the username has been setup correctly and is as you expect it. Remember, the database name will likely have a different prefix between hosting providers, unless you've managed to keep the same login name with each provider. ie, I'm talking about the database prefix here, not the table prefix.
(another note: most database connection issues will result in errors appearing on the page in lieu of your site, which leads me to believe it's at least partially setup correctly.)
TEST: What you can do is rename the old wp-config.php to something else and don't create a new one, then visit the website and it will lead you into setting it up again where you can enter the database details (your site info will still be intact, this will only reset your config file, not the database, although it could reset the connection between the filesystem and database).
3. Domain name propagation and DNS settings with your new host
As I mentioned previously, are you checking the right server? Are you sure the domain name has been propagated (if you're using the same domain name that is).
Check the IP address with your DNS provider (for your domain name) is correctly pointed to your new server
Then check that from your command line by typing ping {your-domain-name} and see that your IP address comes up
Check the DNS settings with your web host are setup correctly and that your domain name points to where you want it to point to (ie, public_html or the relevant subdirectory there-of). (This resally does come back to point one, which if you covered it, this shouldn't be an issue
Check that you dropped the files (and all the files) into the correct physical directory, ie public_html (or sub-dir)
If none of these help, please leave a comment with any further developments you've made and as much info as possible, and we can start looking in other areas.
*notes about the database name:
when playing with WordPress directly, ie in the configuration files or the backend administration settings, the database will include your {username}[underscore or hyphen]{database-name}
when playing in phpMyAdmin, they will already be included and you will just provide the {database-name}.
Fellow this steps
export your sql from cpanel---phpmyadmin
make zip of your files in cpanel
import the file in new domain and extract it
create a database link to the new domain
go to new database which you have reacted through phpmyadmin--delete all the tables which was installed by wordpress.
import that sql file which you have downloaded from old website
and in phpmyadmin change the url to new domain name
Regards
Follow these steps:
export database from phpmyadmin.
zip your WordPress project via c-panel.
upload zip file on new domain via c-panel.
extract zip file.
create new database and import old database in new phpmyadmin.
