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.

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'm developing an installer for my program for Windows OS.
I'd like the installer to check if MySQL is already installed and if it isn't silently install MySQL before installation is over.
How can I check if MySQL is already on the computer with delphi?
Regarding MySQL server:
As #Shirish11 sayd, you can check HKLM\SOFTWARE\MySQL AB. But that does not guarantee anything, as this registry key is optional. MySQL really does not require any "complex" installation procedure, like SQL Server. You can download MySQL as an installer, as just a ZIP archive. In last case the registry key will be not created. The similar with services. Using mysqld.exe --install Kitty --defaults-file=c:\mysql.cfg command line you can create MySQL service with Kitty name. Or even a service may be not created at all.
The MySQL server may be installed not locally, but on a different host. And be administrated by a dedicated DBA. So, you may not need to check / install server at all. Just not your task. If your application is going to install a local server, which will be used only by "this" workstation, then use MySQL Embedded.
In general, you should ask the user about MySQL installation, eg "Do you have MySQL server installed ?". And if user answers "yes", then you can ask him for login parameters (host, port, database, user name, password). If not, then you can suggest him to download it and install, to avoid licensing issues. Because you have to have a license, purchased from Oracle, to distribute the MySQL Server installer with your software.
Regarding MySQL client:
There is no other signs, that libmysql.dll is "installed", than the libmysql.dll presence. You can check for libmysql.dll at Windows folder, at PATH folders. More simple - you can always put it with your EXE.
If you are using dbExpress, then you should use specific libmysql.dll version, supported by EMBT dbExpress driver. So, again, better to put it with your EXE.
See note (3) regarding server licensing. It applies to client too.
Check for this registry entry for MySQL if present
HKEY_LOCAL_MACHINE\SOFTWARE\MySQL AB
If you have MySQL installed then this entry should be present.
If you need some thing more, then check for the service if its present
function ServiceIsPresent(sMachine, sService: PChar): Boolean;
var
SCManHandle, SvcHandle: SC_Handle;
begin
// Open service manager handle.
SCManHandle := OpenSCManager(sMachine, nil, SC_MANAGER_CONNECT);
if (SCManHandle > 0) then
begin
SvcHandle := OpenService(SCManHandle, sService, SERVICE_QUERY_STATUS);
// if Service installed
if (SvcHandle > 0) then
begin
Result := True;
CloseServiceHandle(SvcHandle);
end;
else
Result := False;
CloseServiceHandle(SCManHandle);
end;
end;
function call
ServiceGetStatus(nil,'MySQL');
I have picked up this service name from my registry entries
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services
But be careful while using service check because some people might have different service names for MySQL service.
As in my case I have 2 installations of MySQL hence 2 services are present MySQL,MySQL501.
Hence it will be bit tedious to find out the correct service name.
Mind you HKEY_LOCAL_MACHINE\SOFTWARE\MySQL AB can remain in registry even on uninstall of MySQL. What gets removed is HKEY_LOCAL_MACHINE\SOFTWARE\MySQL AB\MySQL Server 5.1 but since we do not know the MySQL Server 5.1 part in advance, its not easy to go for this approach. Moreover MySQL need not be installed as such.
What is possible is to check HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MySQL\ImagePath and then see if the path specified by the value exists. The second part is important because MySQL need not remove the service key during uninstallation if service is already turned off. So this registry value can remain even after uninstallation. So the best option is to get the path of the executable from the above mentioned registry and then see if the mysqld.exe or (whatever it is) exists. MySQL is not installed if either the registry value doesn't exist or if the file doesnt exist. The catch here is that this logic fails if MySQL is installed but not configured to start its service (which means there is no key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MySQL). But thats trivial, since running MySQL installations will anyway have it and most machines will have MySQL running. Now even if the installed MySQL is not configured to have a service, its quite okay to install another version of your MySQL and register your service first.
I'm unsure of a perfect solution, the reason being MySQL being not a proprietary software. I mean anyone can bundle MySQL and install in their own flavours. For example, wampserver comes with their own MySQL. Client machines most certainly wont have servers installed that way, but we can not rule out the option and we may not want another MySQL instance (Note that a separate instance of MySQL runs fine along with MySQL in wamp server). What I do is check the above, if I did not find, I check for the image path of wamp service, like HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\wampmysqld\ImagePath. It depends on the server you have on a machine.
I need to put the datafiles for mySQL 5.5 community server on a different location than the default (it would be helpful if the log could go there too). Is this something I can do at the command line or after install.
This is on Redhat
It looks the only way to do this is by building from source and specifying the home during Make. I would put down instructions but I am having a devil of a time getting it to build.
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.
Is a portable version of MySQL for Linux available?
You don't need to "install" mysql. Its binaries will run from any directory (given appropriate search paths etc), and its configuration can be specified entirely on the command-line, if necessary, bypassing the likes of /etc/my.cnf, or by specifying an alternative config file with arbitrary path.
Some engines can work with a readonly data directory (MyISAM, Archive), others may require a read/write data directory (Innodb) but that could be a temporary area or ramdisc.
There's nothing "un-portable" about MySQL.
To have a Portable Version of MySQL in linux, you can compile it to a Generic location
./configure --prefix=/myworkspace/installs/mysql --exec-prefix=/myworkspace/installs/mysql
Then usual
make
make install
this will install mysql on /myworkspace/installs/mysql. Then you can zip the whole mysql folder and can take it anywhere except you can run it from the same directory structure you have installed. Compiling mysql requires some dependencies, check it out here http://dev.mysql.com/doc/refman/5.6/en/source-installation.html .
If you install these dependencies also in /myworkspace/installs/mysqldepends/ , then your mysql is totally portable.
MySQL Embedded Server is available for purchase.
I advice you to use SQLite
