When I try to access my WordPress site as localhost
, I get:
Error establishing a database connection`.
How can I debug this problem? Where are logs I can see?
I am able to login to MySQL with user wordpressuser
on localhost
. I seem to have correct grants for wordpressuser
on database wordpress
:
root@myhost# mysql -hlocalhost -uwordpressuser -pmypassword

Password for MySQL user wordpressuser:
Sorry,
An error occured when trying to connect to the database
with the grant-tables:
* Maybe YOU do not have READ-access to this database?
* If you used the -U option, you may have supplied an invalid username?
for the superuser?
* If you used the -U option, it may be possible you have to supply
a superuser-password to, with the -P option?
* If you used the -P option, you may have supplied an invalid password?

My wp-config

How can I debug this problem?
