'Incorrect user or password' when logging in. PHP 'Connection refused'

L2 Linker

I appear to have a php connection issue to my database on my Expedition instance.

 

When trying to upgrade Expedition to the latest version I get the following error.

Any thoughts on how to resolve the issue?

I resolved the issue by doing the following:

 

I had to remove the tc.log file as it became corrupt.

sudo rm /var/lib/mysql/tc.log

 

I then reinstalled expedition

sudo apt-get install --reinstall expedition-beta

Hello @BOkay 

Could you please try below steps :

1. In Setting-> M. Learning-> Server information-> Expedition ML address, trying to set the Expedition IP to 127.0.0.1 , this will fall back to Expedition server IP and click “Save”. This step will re-initiate the database connections. (If Expedition is behind a different IP or NATed IP , you would need to put the real IP as ML IP not the NATed IP ) , check the IP using ifconfig.  (Most cases, this step should fix your Database connection issue, if not, continue to step 2)

2. Go to #more /home/userSpace/userDefinitions.php review the parameters in the files look like below:

define ('DBServer' , '127.0.0.1');

define ('DBUser',  'root');

define ('DBPass', 'paloalto');

define ('DBName' ,'project_schema');

define ('PARSER_max_execution_time','10000');

define ('PARSER_max_execution_memory','1G');

define ('DBSQL_LOG_BIN', 0);

 

3. Issue SQL commands to check which IPs were being allowed. 

#mysql -uroot -ppaloalto

 

expedition@expedition-documentation:~$ mysql -uroot -ppaloalto

 

Welcome to the MariaDB monitor.  Commands end with ; or \g.

| localhost                | root             |

+--------------------------+------------------+

6 rows in set (0.00 sec)

 

Verified Expedition IP and User Root is showing up as above

 

4. Check that /etc/mysql/my.cnf is correctly setup not bind to 127.0.0.1. There is a health check in the dashboard that checks this as well. 

 

Make sure below line is commented out:

 

# The following values assume you have at least 32M ram

/127.0.0.1

...skipping

# Instead of skip-networking the default is now to listen only on

# localhost which is more compatible and is not less secure.

#bind-address = 127.0.0.1

 

Thanks. Here are the results.

 

1) I can't login via GUI

2) My parameters match

3) ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2 "No such file or directory")

4) My parameters are correct, the proper things are commented out.

Hi @BOkay 
have you ran “sudo apt-get upgrade” by mistake ? We have seen user can’t login to GUI after did a “sudo apt-get upgrade “ 

Nope, I did sudo apt-get update and sudo apt-get install expedition-beta.  

 

I used command line history and just verified now.

Hello BOkay,

The error could be that the MySQL is not listening to ports. Do a

I resolved the issue by doing the following:

 

I had to remove the tc.log file as it became corrupt.

sudo rm /var/lib/mysql/tc.log

 

I then reinstalled expedition

sudo apt-get install --reinstall expedition-beta

 

@BOkay Thank you for sharing the solution!
