Could you change the bind-address=localhost and restart MySQL server? Seems like this issue is related to yours: http://forums.mysql.com/read.php?152,355740,355742#msg-355742
Also this-
If MySQL port is wrong result is MySQL client error 2013 "Lost
connection ...". Note that this error also occurs if port forwarding
is disabled in SSH configuration (the configuration parameter
'AllowTcpForwarding' is set to 'no' in the 'sshd_config' file). It
(here) simply tells that there is no connection from SSH to MySQL for
some reason. But the mySQL client API 'thinks' there was one
connection and that is why is says 'Lost connection ...' and not
'Can’t connect...'. There was one successful connection - but not to
the MySQL server - to the SSH daemon only! But the MySQL client API is
not designed to 'see' the difference!

MySql Workbench, Can't connect to MySQL server on 'localhost' (10061) (2003)

This might seem like a duplicate but trust me its not
So you guys are probably familiar with the error. The server doesnt start at the beginning and when i try to start it from Startup/Shutdown it gives this error.
Most of the people with this problem fixed it by starting MySQL server manually. Yeah but problem is mine was already working, i mean the server is on both in services and task manager. But for some reason im getting this error.
So my question is, how can i fix this?
- Checking server status...
- Trying to connect to MySQL...
- Can't connect to MySQL server on 'localhost' (10061) (2003)
- Assuming server is not running
Tried finding some logs but all says the same as above
Oh and i tried shutting the server down and opening again
Do you guys think that it might be happening because it is conflicting with some other sql program? I uninstalled everything related to sql but i might miss some stuff.
Programs i used to have are
-XAMP
-SQL Manager
-Microsoft SQL Server
-Microsoft SQL Server Management Studio
Like I said though, i uninstalled them all.
You need to check for all the mysql configuration files in /etc/mysql and check for any lines containing 127.0.0.1 and bound address or skip network and comment them.
Hope it helps.
It seems like for some reason it was having a conflict with other connection or port was just wrong on set up. I tried deleting all the connections i have and started a fresh one and it worked. Weird right? Here i was thinking when you uninstall MySQL, it woudl delete all the connections too.

Cannot connect to MySql database from Eclipse : java/sql/SQLException

I have set up a database with MySql.
I want to connect to it from Eclipse.
I followed the same steps as mentioned in this link:
https://www.zkoss.org/wiki/Setup_MySQL_DB_in_Eclipse
So I am using this library for the driver:
mysql-connector-java-5.1.45
whhich I think is correct
The name of my database is "test" and the port used by MySql is 3306.
This is my configuration:
But when I test the connection it's giving me an error message :
"An internal error occurred during: "Ping server job". java/sql/SQLException"
I have looked more in details in the error log and I see error like this:
java.lang.NoClassDefFoundError: java/sql/Connection
I have turned off my firewall just to check, but it does not solve the issue.
Can someone tell me what I should check?
Thanks
I use Java version 1.7.0_80 and Eclipse Mars.2 Release (4.5.2).
I gave up and used MysQL Workbench which meets my needs.

SQlite to MySQL migration for Seafile Server

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.

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

MySQL Error 2013

I am facing connection failure to MySQL problem when I run my program for more than couple of days.MySQL Error Code is 2013 while connecting to Database. MySQL server and client programs are both on same machine. I am using FC5 as my OS and MySQL version is 5.0.18. Can anybody throw some light on this?
I am getting mysql error 2013 while calling mysql_real_connect()...
Any help is appreciated.
Try using localhost, instead of your own IP.
I don't know why, but this immediately fixed the problem for me.
I would be very grateful if someone could clarify
why this worked, all of a sudden.
Sounds like a firewall issue. Have you tried disabling the firewall temporarily?
Another possible solution involves edition the startup script as mentioned here and commenting out the following line:
SKIP=skip-networking
A third possible solution is mentioned here. The user tried to access an InnoDB database and InnoDB support was accidentially deactivated for the MySQL server.
(new) I found this official MySQL article which has lots of approaches to solve the problem. Did you modify the wait_timeout system variable?
Here's an answer you might not expect. I had encountered the same problem. MySQL Error 2013. Here are the symptoms:
PHPMyAdmin fired off 2013 and error 95.
I could shell into the MySQL monitor, but it took an inordinately long time to start. I could view tables and everything worked once the command line utility started
The server took a LONG time to stop and restart.
No errors in the MySQL error log.
I work with a good sysadmin who checked netstat -tn, which yielded the answer:
tcp 0 0 [my.srv.ip]:3306 184.73.87.215:59271 ESTABLISHED
tcp 0 1 [my.srv.ip]:38138 184.73.87.215:113 SYN_SENT
The IP resolves to Amazon Web Services. Some prick was leeching onto my 3306, even though everything but port 80 is allow-only. It's time to review my firewall rules.
There were no new tables, and mtop didn't show any activity, but I found a ton of these in the auth log:
Apr 19 15:14:52 magic2 mysqld[18953]: refused connect from ec2-184-73-87-215.compute-1.amazonaws.com
Apr 19 15:18:02 magic2 mysqld[18953]: refused connect from ec2-184-73-87-215.compute-1.amazonaws.com
After blocking the offending IP in iptables, the problem suddenly went away. Sneaky Bastards. The moral of this story is: What looks like bug, might be a hacker.

Check your my.cnf. Set your bind-address to the server's IP address. Solved the issue for me. NO ONE seemed to know the answer to that one!
My fix was - change 'localhost' to '127.0.0.1'
It could be a network error that caused the TCP/IP connection to drop, or the wait_timeout was exceeded on the server; the latter can actually be useful in keeping the # of open connections down, but the app will then need to handle errorcode 2013 correctly!!
