SQL Cannot connect to database server - mysql

Currently I have been working with MySQL on Mac OSX. I have MySql Workbench and MySql installed, along with commands on Terminal, but every time I try to open a database it comes up with this:
Could someone explain what I have done wrong? I have tried everything (commands, reinstalling MySQL...)

There is a mistake in ip address . make sure you use correct format. if you use it locally give "127.0.0.1:3306" or "localhost:3306"

"8.0.13:3306" is not a legal "ip:port" format, make sure you've entered a correct IP address such as "10.8.0.13:3306"

MySQL 8.0 Command Line Client crashes right after entering the correct password

MySQL 8.0 Command Line Client crashes right after entering the correct password. I have also checked in services and there is no problem there. I'm using windows
This might be because MYSQL service is stopped.
Open search bar in windows and type services
Open the services application and find MYSQL application.
Click on start
Now open sql command line and try entering password
It is because MySQL Server stop, may be you run another application that use the same port. Try to run MySQL Installer Community, and you will find the program that you have to reconfigure (blue text). Try to configure MySQL Server ant click Test Connection.
It's hard to tell with no debug output or error codes, but disabling ssl might do the trick:
mysql --ssl-mode=DISABLED --host=$MYSQL_HOST --user=$MYSQL_USER ....
I had the same issue, was looking through Google to find an answer and came here. Are you sure, that you provided MySQL password? The root cause of my problem was the fact, that I put the MySQL user instead of MySQL password (the root one). Now everything is working fine.
That could mean that the password is failing. Check CapsLock key.
Go to Control Panel and uninstall MySQL Server only, you don't need to unstall the other MySQL files.
As mentioned here, make sure you can see hidden folders and then delete the following folders:
C:\Program Files\MySQL
C:\Program Files (x86)\MySQL
C:\ProgramData\MySQL
C:\Users<your-username>\AppData\Roaming\MySQL
Reinstall MySQL Server Package only
Select another password (looks like the current password is the problem)
Come here and vote me up :)
Do something nice for someone else ;)

MySQL Workbench: "Can't connect to MySQL server on 127.0.0.1' (10061)" error

I apologise.. I know this question has been asked many times before, but I've tried lots of suggestions, and simply can't find a solution.
The problem: I have a MySQL database running on a hosted server.
I have to use SSH to connect to it, and I have the relevant Public and Private Key files.
I specifically want to use the PC version of MySQL Workbench, to access this database, for running queries, checking data, etc.
If I run Sequel Pro on a Mac, it connects fine, and I can browse and query the database. No problems.
If I run the trial version of SQLyog on a PC, it also connects fine. No problems.
But if I try to connect use MySQL's own "MySQL Workbench" application, using exactly the same settings and SSH Private Key file, it refuses to connect, throwing the well-known error:
Can't connect to MySQL server on 127.0.0.1' (10061)
I find it frustrating, as, in SQL Workbench, I specified the "MySQL Hostname" to use, db01.mysql.vm.MyHostingServer.net, but Workbench seems to ignore it, and demand to connect to 127.0.0.1 instead.
(I have read that Workbench says it needs the Public key file, but actually means the Private key file... and I have tried with both. I've also tried with MySQL Workbench on a Mac, but that crashed all over the place, simply when I was typing in server names and passwords.. it was a mess !!)
The hosting service I've gone with gives me limited permissions for changing MySQL settings, and given that Sequel Pro and SQLyog can connect successfully, I don't want to start messing about and changing things randomly.
Any ideas...?
Maybe you are not allowed to start the service "MySQL 55". Set the login information of Service "MySQL 55" as local!
To see the list of aviable services in Windows 7:
Open a run box
Type services.msc and press return.
Find the service MySQL55
A right click of the MySQL55 Local Service shows Properties -> Log On
Even I had same problem, The reason was mysql service was not getting configured properly, when I installed it through 'MySQL installer'. Also it was not starting, when I tried to start the service manually.
So in my case it seemed be a Bug with the 'MySQL Installer', as editing the install path to a different one when the 'Developer default' was selected, the problem occurs.
Solution (Not exactly a solution):
Uninstalled the MySQL all products (completely)
Reinstalled, this time also I have selected 'Developer default', but didn't make any changes to the path or any thing. So the path was just 'C:\Program Files\MySQL' (the default one)
And just clicked Next Next...
Done, this time MySql was running fine.
After making above improvement such as checking if mysql service is running or not, you just need to give a small password while creating connection, it is ' ' or 1 time press on space-bar in case of GUI or workbench. After which you just need to validate your machine with server (validated HOST). For that purpose click on 'New Server Instance' and it will configure server/HOST on your behalf itself.
I have done this successfully just a few couple of minutes ago. My workbench software is able to show all pre-installed databases etc now.
hope it will work for you as well.
Thanks!!!
I was having same issue, way i have resolved is:
opened the MySQL installer. i was having a Reconfigure link on MYSQL Server row.
Clicked on it, it does reinstalled MySQL Server.
after that opened MySQL Workbench, and it was working fine.
Try placing the host name (db01.mysql.vm.MyHostingServer.net) in your windows host (C:\windows\system32\drivers\etc\host) file along with it's IP address and port number and see if that helps.
If you have installed WAMP on your machine, please make sure that it is running. Do not EXIT the WAMP from tray menu since it will stop the MySQL Server.
To connect to a new server, you click on home + add new connection. Put IP or webserver URL in new connection.
Just try to run the following command manually:
C:\wamp\bin\mysql\mysql5.6.17\bin\mysqld.exe --console
It worked for me :)
Ran into the exact same problem as OP and found that leaving the "MySQL Server Port" empty in the MySQL Workbench connection solves the issue.
I have tried all the method.
I will suggest you to reinstall it.

Failed to connect to MySQL at 127.0.0.1 in MySQL Workbench. System error 61

I'm running into a little trouble with MySQL Workbench.
This is the situation, I'm developing a database to query it remotely from Android devices. This is the first time I use MySQL Workbench, so I've followed this tutorial:
http://net.tutsplus.com/tutorials/databases/visual-database-creation-with-mysql-workbench/
I have no problem creating the EER diagram and generating the SQL script. The problem comes when I try to connect to a MySQL server. I get this error:
"Failed to Connect to MySQL at 127.0.0.1:3306 with user root. Lost connection to MySQL server at 'reading initial communication packet', system error: 61"
http://img101.imageshack.us/i/capturadepantalla201104i.png/ (if the link stops working tell me)
I've also tried using the Local Socket/Pipe connection method with the MAMP Socket in '/Applications/MAMP/tmp/mysql/mysql.sock', but it gives the same error. And I've also tried using MAMP port 8889 but still nothing.
So anyone knows how to fix it? And another question, can I connect from my Android device to my laptop(where the database is placed) without using MAMP? MySQL needs MAMP to serve queries? And the last thing, am I going into the right way? Or should I do it other way?
Thanks for reading.
I had the same issue, but part of your question is what fixed it for me:
Set connection = Local Socket/Pipe
Set socket path = "/Applications/MAMP/tmp/mysql/mysql.sock" (for me - I got the path from my MySQL log upon initialisation)
Running: MBP, OSX 10.8.3 (Mountain Lion), MAMP Pro
Can't really fathom any further what your issue may be, but perhaps double check your DB is properly initialised. But, perhaps this helps someone else :)
I typed: sudo /usr/local/mysql/support-files/mysql.server start
into the terminal and it started the MySQL server successfully and I was able to connect to MYSQL workbench.
You need to sure that Mysql process is running in your system. not sure in MAC but in windows it'called mysqld.exe
well take a look
http://lists.mysql.com/mysql/124371
Most commonly happens when database/server is not running. You need to check your server, or restart it. You can do so if you have mysql workbench under server administration. Check your manual for restarting or starting the server.
On osx 10.6 using mamp pro I solved this by allowing network access in the MySQL tab from the home window. Hope it saves someone the pain too
When trying to use the MySQL Workbench and connect through an SSH tunnel, you will get this error when your SSH connection does not complete successfully (e.g. improper host, password, key file, etc)
A good way to trouble shoot this is to separately test the the ssh connection from the machine you are trying to connect from and establish that you can do so successfully.
Try closing MySQL and running it as the admin. This worked for me.

I solved it! On a mac just go to spotlight search on the top right of the screen and type Mysql. Turn it on.

Database query on MYSQL

I had installed Zend Server CE in my laptop and i have tried to open my phpMyAdmin page via my email address but i got following message ie (#1045 Cannot log in to the MySQL server). what is the possible solution.
Error #1045 means that you have provided wrong username or password.
http://dev.mysql.com/doc/refman/5.0/en/error-messages-server.html#error_er_access_denied_error
What have you already tried? Knowing nothing of that, here is what I would check:
Is there a MySQL server installed?
Is it running?
Can you use the MySQL command-line client to connect to the MySQL daemon?
That last step prompts its own series of troubleshooting steps, which mostly boil down to "are you using the right username/password and does that user have appropriate permissions." If you don't know how to suss that out, you should do some more research.

Ruby on Rails application could not be started (mysql error 2002)

Then a looong list of backtraces whitch dont really help me.
The Socket file does NOT exist, and i cant find it on other places.
Please help me, this is making me crazy.
Thanks for your time & help
I appears that your mysql server is not running. You should debug that portion of your system before looking at your rails app.
A few things to checK:
Can you connect from the command line?
Are there startup errors in your mysql log file?
Did you change IP addresses, share names or anything else that might have stuffed your mysql install?
I solved the Problem!
Reinstalling the 10.6.5 Combo Update helped.
-Download the correct Combo Update (same version (server/normal), same build)
-Stop the Services (like Web and so on..)
-Install the Update
-Restart
-Start Services
-All should work again
Thanks to all of you guys for their help.
