Hi I'm logging slow queries because we're having some performance
issues and I have read about mysqldumpslow and thought that would be a good
way to sort through the queries.
At the command prompt, I type mysqldumpslow and I get this:
'mysqldumpslow' is not recognized as
an internal or external command,
operable program or batch file.
I'm using MySQL version 5.0.79 on Windows Vista.
Note:
c:\Program Files\MySQL\MySQL Server 5.0\bin is my path and I have searched the drive for 'mysqldumpslow' and can not find it.
What am I doing wrong?
Note:
MySql 5.0.x does support the mysqldumpslow command follow this link to manual
edit : oops, I read the manual wrong, and gave wrong information :-( sorry :-( let's give it another try...
I've just installed MySQL on windows, to try using mysqldumpslow, and I don't have mysqldumpslow installed either :-( So, you are not alone, and it doesn't seem to be a problem with your install (I've tried 5.1.x, but as you highlighted, it should be the same for 5.0.x)
Looking at the "mysqldumpslow" I have under Linux, it appears it is a Perl script ; and Perl is not often installed on a Windows machine. Maybe that would be a hint to a solution...
Well, after a bit more testing, when installing MySQL, it seems you have to select "Developpers Components > Scripts, examples", which is not installed by default (at least on windows) -- no need to reinstall everything : you can "modify" the installation, to add this option.
Then, you will have a "script" directory next to the "bin" one.
For instance, on your install, it should be something like "c:\Program Files\MySQL\MySQL Server 5.0\scripts".
In this directory, there are some scripts ; one of them is mysqldumpslow.pl ; which is what you are looking for ;-)
Now, you "just" have to get Perl installed and running on your machine (sorry, I've never installed Perl on windows ; but you can find some informations here)
Hope this helps better than what I posted before !
try typing
whereis mysqldumpslow
If that still says its not installed,
EDIT: Above is not relevant, as on windows. Missed that, thanks to commenter for pointing it out.
I always use mysqlsla (mysql slow log analyser) ahead of mysqldumpslow - you could give that a go.

Mysqldumpslow is a Perl script so under Windows you will need to make
sure you have Perl installed and will need to explicitly invoke it via
Perl.
The way the script is set up it will work automatically under Unix
because Unix has the ability to run scripts directly by identifying the
correct script processor from the first line of the script. Of course
you still need Perl installed, but that is taken for granted in most
Unix installations.
Or you can also try to set the path in Windows environment variables.

So I am going crazy with this. I have MAMP installed and it's MySQL is working fine. I now installed MySQL 5.7.19 from the official dmg from their site and installed.
From the pref panel I am not getting status updates and as such I cannot stop it even though it is running. Trivial though as I can launctl unload it.
However, the big issue I am facing is that although the server starts correctly (from pref panel) and I can see the process running and the respective /tmp/mysql.sock file when I try to run mysql in terminal (or any other mysql command) I get an error stating it cant find the sock file and it pipes out the Applications/MAMP path.
I looked everywhere for a my.cnf that might be setting this and there are none (apart from the one used by MAMP). No environment variables set to override it, nothing. In fact, there are no other my.cnf files but for some reason it still thinks it should be using /Applications/MAMP path.
my_print_defaults client confirms this as it pipes out
--socket=/Applications/MAMP/tmp/mysql/mysql.sock
but I have absolutely no idea where and how this is being set and I need to be able to run on this instance terminal commands. Driving me crazy for hours now.
No files at
/etc/my.cnf /etc/mysql/my.cnf /usr/local/mysql/etc/my.cnf ~/.my.cnf
No environment variable MYSQL_UNIX_PORT as described here: https://dev.mysql.com/doc/refman/5.7/en/problems-with-mysql-sock.html
So how the heck is it getting this value?
Also checked at DATA_DIR and BASE_DIR, no my.cnf there either.
Obviously Ive done which mysql to confirm I am calling the correct binary.
Any help much appreciated!
UPDATE Running my_print_defaults client --verbose --no-defaults pipes the same exact output, so I am guessing it is somehow set elsewhere. Where can this variable be set otherwise?
Ok so I found the answer after all and sharing it for anyone having the same issue.
In essence, the --socket parameter is added via the ~/.mylogin.cnf file!
I am not sure if I ever added it there but I am pretty sure it wasn't me, so I am guessing MAMP did it.
This is an encrypted file so you can't edit it directly by you can change it via mysql_config_editor:
mysql_config_editor remove --socket
And problem solved!
This is NOT about MySQL's "data directory".
When I log into MySQL on my machine (Windows 10 OS) I know that MySQL still has a "current working directory": importing a .sql file works, giving only the filename, if the file is located in the same directory as the one where I went
> mysql -u ....
So I wondered whether it was possible to get the CWD when actually logged into MySQL. Then I wondered whether it might be possible to change it, i.e. to navigate somewhere else. Then I wondered about running system (i.e. command prompt) commands generally, while still logged in to MySQL.
Here we see a claim that you can indeed do all these things... by going something like:
\! ls -l
On my machine this doesn't work... probably because it's not a Linux OS. I get unknown command '\!'...
Is there any way to do this in Windows?
You're right. The Windows version of the mysql command line client lacks the shell escape \! command.
It is an open source project :-). You or I could give them a pull request with a fix. But then we'd have to decide whether we wanted cmd or powershell in the escaped process.
Perhaps not really a suitable SO question but I'll give it a try.
When I try to dump my DB from the remote server, my MySQL workbench for MacOS tells me:
Applications/MySQLWorkbench.app/Contents/MacOS/mysqldump is version 5.7.12, but the MySQL Server to be dumped has version 5.7.15.
Because the version of mysqldump is older than the server, some features may not be backed up properly.
It is recommended you upgrade your local MySQL client programs, including mysqldump, to a version equal to or newer than that of the target server.
The path to the dump tool must then be set in Preferences -> Administrator -> Path to mysqldump Tool:
I have version 6.3 installed, and the built-in "check for updates" only tells me I already have the latest version.
Does anyone know where I can go to download this more recent dump tool? I looked around on the MySQL.com but couldn't find it.
There's a simple way to solve your problem.
Just go on google type: mysqldump 5.7.20 (this number is the version are you looking for, in my case is 5.7.20)
choose the link site from https://dev.mysql.com/downloads/mysql/
on that page scroll down until you see a list of avaible downloads, choose your operating system (in my case is Windows) then... download the zip that has the version you are looking for.
unzip that folder... go to bin inside it... from there copy mysqldump and paste it into your MySQLWorkbench folder... (replacing the one is in there)
restart your MySQLWorkbench... and that is all.
You just need to update the mysqldump.exe.The up to date version of the exe can be found in. To solve the issue just go to Edit->Preferences->Administrator ,and browse the following path
for example C:\Program Files\MySQL\MySQL Workbench CE 5.2.47\mysqldump.exe
If for some reason you have two separate installations of the SQL server, you might be pointing to the wrong sqldump.
I have been using MySQL Tuner (http://mysqltuner.com) on Linux for a while and am quite comfortable with it. Now, for whichever reason, we have had to start hosting other websites on IIS. Is there a similar tuning utility that may recommend config changes to MySQL on Windows Server 2008?
Kind regards
I have just ported the mysqltuner.pl script to Windows - see http://mysqltuner.codeplex.com/. It uses the same checks as version 1.2 of the mysqltuner.pl script, but in a nice, friendly Windows application - no need to install Cygwin or Perl.
Ok so this is over a year after the question but I thought it relevant because you can actually still use the mysqltuner script if you combine it with Cygwin.
Install Cygwin
Make sure Perl is installed
Additionally I installed the mysql and the mysqld packages as well (Needed for the script to connect to a "remote" MySQL.
Copy the mysqltuner.pl script to your Cygwin user home directory (Found under cygwin_install_dir/home/your.user)
Start the Cygwin terminal
Run the script $ perl mysqltuner.pl --host mysql_host_ip --forcemem 512
If you encounter an error in the line of:
ERROR 1130 (HY000): Host 'somename.company.com' is not allowed to connect to this MySQL server
Go to the database server and add the appropriate user and privelages
You should now be able to use mysqltuner in a windows environment against local as well as remote MySQL servers.
...screenshots removed because I'm not allowed to use images yet, sorry.
Don't know of another tool (outside the MySQL Instance Configuration Wizard you can run) like mysqltuner which will not run unfortunately. You can install Perl on Windows, but when run the .pl file you will get an error about $PATH not having mysqladmin in it. Upon reading of the manual laughing, it plain as day states there is no Windows support for 1.2.0 version of tool.
You can see if these suggestions help in the interim:

Edit: I just found this: http://www.webyog.com/webyog/monyogscreenshots
MONyog, it is a paid product, though. I installed the trial and it looks very promising. It monitors your SQL server and gives you alerts and recommendations based on those alerts. Might be worth a look. I cannot vouch for too much other than it has some nice information in just a short period of time.
I need to adapt our testing server to our production one that is stored on Aruba.
Aruba use MySql 4.0.30 but I can't find them nowhere!
Anybody know where can I find it ? or anybody has the installer stored anywhere?

According to http://lists.mysql.com/mysql/210800 (an email from a MySQL employee) this is a non-public release for customers who are too inflexible to upgrade. It says you can pay for "extended support" to get it.
Here for you source: http://mirror.provenscaling.com/mysql/community/source/4.0/mysql-4.0.30.tar.gz
Binaries only there for 4.1: http://mirror.provenscaling.com/mysql/community/binaries/4.1/
MySQL does not require much installation steps like most windows software.
Just copy the mysql dir and the mysql data dir from the production environment to your local machine and start mysqld.exe (does not need to be run as a service) from the bin directory with:
mysqld.exe --defaults-file="C:\path\to\my.ini" MySQL
If it does not start, you most likely tweak some path entries in your my.ini.
Or you can install the latest 4.x Server you find and replace the binaries and data files with the ones you get from production. That should totally do it.
