In the last ~week, my CakePHP site has been unable to connect to a MySQL database. Everything is hosted by NearlyFreeSpeech.net and I don't see any problems with the financial aspects of my account.
Does anyone know what's going on?
I'm able to connect to the database with phpMyAdmin and my automated mysqldump calls have worked fine, so I didn't find out right away.
I tried putting up a new CakePHP site using a fresh download from CakePHP but I get the same error message:
Warning (2): PDO::__construct() [pdo.--construct]: [2002] Operation timed out (trying to connect via tcp://cakeht.db:3306) [CORE/Cake/Model/Datasource/Database/Mysql.php, line 177]
Cake is NOT able to connect to the database.
Database connection "Mysql" is missing, or could not be created.
SQLSTATE[HY000] [2002] Operation timed out
Does anyone have any advice?
The problem was magically fixed with the passage of time.
The solution then, is to simply wait an unknown number of days.

I am receiving a lot of error reports from my Django server throwing:
(2005, "Unknown MySQL server host 'my-address.us-east-1.rds.amazonaws.com' (0)").
The server has been connecting to this database for more than a year without any issue. But this morning I suddenly started to receive this error, even though I didn't do any changes to the code.
Furthermore, when I connect to my website, it actually loads data from the database fine.
Apparently there is a random chance that it won't manage to connect?
Any idea what can cause that and how to fix it?
I am on Amazon lightsail.
There is an active AWS DNS resolving incident in us-east-1 region. Seems like it will be mitigated soon.

UPDATE: The issue is now resolved as updated by AWS.
I'm working on a project with a DB and whe are using phpMyAdmin.co for administration and I'm not able to connect with my DB administration (phpMyadmin) anymore (yesterday was the last time it worked).
I have tried to reach my host sql7 and phpMyadmin.co and they both didn't work. They where offline.
I've already looked here for the error "Too many connection" and they say I need to adjust something in my administration. But since I can't reach phpMyadmin It's not possible the do that.
Error: Authentication to host 'sql7.freemysqlhosting.net' for user 'sql7269519' using method 'mysql_native_password' failed with message: Too many connections'
Does anyone know if there are some issues with phpMyadmin.co or is there a problem with my code.
Please can someone help, I am tearing out what little hair I have left.
I had to move a clients Magento from one 1and1 server to another and I am getting the above error message when trying to access the site. Whilst 1and1 server support has tried to be helpful their Magento knowledge is limited and I am not getting very far.
Initially I was told to just upload the Magento files and database onto the new server after which I was getting the above error report. After three days of trying to get help at 1and1 someone said that I should have installed Magento first through Plesk and then uploaded the files. I duly did this and prior to uploading the original files Magento was actually working with the basic installation page and I could get access to Admin but after uploading the files and the database I am back to the square one.
I have checked over and over again the local.xml with the settings in Plesk and as far as I can see the database settings are correct.
The database can be seen in ssh command line. I have restarted the server.
In your env.php under the 'db' section, the value of the host,dbname, username, and password should be set properly. If your facing this issue at your local with the host then set 'host' => 'localhost', or 'host' => '127.0.0.1'
After reading multiple questions of users with problems like:
forgot password
installed multiple instances of MySQL
forgot to start MySQL
etc. etc
I started to consider if it is actually possible to conclude from the error page if MySQL is running at all?
Questions with the same type of answers:
mysql said: Cannot connect: invalid settings. xampp
phpMyAdmin - can't connect - invalid setings - ever since I added a root password - locked out
MySQL Says: Cannot connect: invalid settings
But does the error page actually say this is a mysql server response or it couldn't connect (server isn't running for instance)
Take the following code:
<?php
//Step1
$db = mysqli_connect('localhost','username','password','database_name')
or die('Error connecting to MySQL server.');
?>
If one of the inputs is incorrect you will get the error:
Error connecting to MySQL server.
This could be modified into a nice looking error message (as the image above).
So does the error actually prove that MySQL is running or not?
I found a video of a walkthrough on how to fix this error. In the video you can see the servers are running. I was pretty curious about this whole issue.
Link to Youtube:
https://www.youtube.com/watch?v=8fK_DYvosA8
I'm assuming if that's how it worked for the video, that's how it works in general. I'm working off the idea that something can't give you an error message unless it's running.
Sort of. phpMyAdmin generally returns the error message that it gets from MySQL, so for instance if the isn't a MySQL daemon listening on on the TCP/IP protocol, phpMyAdmin shows:
#2003 - Can't connect to MySQL server on '127.0.0.1' (111) — The server is not responding.
For an incorrect username or password, the error message is:
#1045 - Access denied for user 'root'#'localhost' (using password: YES)
"Invalid settings" usually means you have conflicting directives or incorrect information in one of your configuration statements. Without seeing your config.inc.php it's difficult to guess what's wrong here, but this also can mean something went wrong between the PHP library itself and MySQL.
The rejected connection message you posted can also have several causes.
Basically, to directly answer your question, you often can tell based on the error message returned by MySQL or the PHP library (which is the message phpMyAdmin shows). "Can't connect" means phpMyAdmin couldn't get any response from the MySQL daemon, which could have several causes but most often means MySQL isn't running. Most of the other error messages mean it's running but there was a problem connecting. Generally the error message contains some information about why.
I have successfully got Seafile Server fully working with HTTPS.
However I'm trying to migrate from SQLite to MySQL and everytime I try, the seafile server stops working.
I'm not sure what information to put here that yous will need but happy to provide what ever you need.
I followed this guide Deploy Seafile Windows Server With MySQL
Its really frustrating, I dont understand why its not working. I also installed MySQL Workbench and I can see the seafile user with privileges and the databases populated with the tables.
Are there any messages in the logs?
Please look at the logs in /seafile/logs/
You will see an error message in seafile.log if you have problems with MySQL.
For example:
../common/seaf-db.c(123): Failed to get database connection:
Failed to connect to MySQL: Can't connect to MySQL server on '127.0.0.1' (107).
http-server.c(761): DB error when check repo existence.
Disconnected from daemon
I have done such migration already and it did work without problems.
