I want to use same database on my Ubuntu installation as of Windows 7, I've already changed datadir in my /opt/lampp/etc/my.cnf and /etc/mysql/my.cnf to Windows path like this: /media/Data/xampp/mysql/data but it still doesn't work how can I connect to database from Windows installation?
You could "update" databases on a set interval using cronjobs.
Here is how to "sync" 2 databases on remote hosts
Here is how to establish cronjobs
A disadvantage would be that you'd have to dump the entire database which could dramatically slow down the process.
Please note that those articles are exclusively related to some linux distros.

This is very novice question I am very new to working with Databases, primarily an user of R, also comfortable Bash Unix Shell. I have a MySQL server 5.7 installed on windows 10 laptop and have been using Workbench for accessing or populating databases.
I want to have a good command of in-database analytics and had a few broad questions.
Its easy to access MySQL database on my laptop from R on my laptop that was simple. Also if I go to windows command line and type mysql -u -root -p from the directory MySQL/MySQL Server 5.7/bin in can start typing SQL commands at mysql prompt.
My question is, regarding accessing my MySQL databases in my laptop or any other mysql server. From a remote Linux session on a VM, or after starting R in that Linux session. I linux can I install a mysql client alone on a Linux VM and access MySQL databases or do I have to install MySQL server as well.
My premonition was that I wouldn't have to install the server but I was experimenting in Windows Linux Subsystem(WLS) (which is a source of confusion itself since WLS is a new thing and I didn't want to generalize what I learn from experimenting in WLS to working from a remote Linux machine.
Then there is another question of working off a Linux in Virtual Box installed on my windows.
To simplify my question I would like at least know be certain about does one need to install mysql server to and have it running to access any mysql database on another machine or will it suffice to have a mysql client installed?
Your input will be greatly appreciated, as I have been only successful in trying to use my WLS and read several post/blogs I would like to be clear about how MySQL works before continuing my experiments.
Ideally I would like to query data from any bash shell that I can find or any R session.
Thanks
No, you do not need to install mysql server on a computer to be able to access another mysql server remotely. The client will suffice.
This may be basic question but I am pretty new to MySQL and server setup. I am going to install a different os where I will have LAMP setup, earlier I installed on Rasbian Jessie each of those manually.
How do I backup and restore to a different server.
Just install MySQL server and you will able to connect to DB from any environment. Also you can connect to remote database if you have some host for example
I was on windows and using XAMPP(installed somewhere else than C:/ )
Now i have moved on to LINUX and installed LAMPP.
So, i have this XAMPP folder from windows and i copied the project files from htdocs and now i need the database which i didn't exported while i was on windows.
I tried to copy the phpmyadmin folder from the old XAMPP folder but couldn't get it to work.
So how can i access the previous OS phpmyadmin to use my existing databases -
using linux (MINT - rosa-cinnamon)
Thanks in Advance !
If you want to move databases between hosts - especially when there are differences in the MySQL daemon version, operating systems (-versions) or storage schema - you should create a MySQL dump at host A and import it on host B: http://dev.mysql.com/doc/refman/5.7/en/mysqldump-sql-format.html
If this is no option for you anymore, you can try to move the old MySQL data directory (Configured in my.ini on windows, somewhere in the xampp directory) to the location where the new MySQL daemon stores its data files (Normally configured at /etc/mysql.my.cnf). A few more hints on this:
Ensure to modify the file permissions on the data files at the new location that the MySQL daemon can work with them.
On Windows, MySQL table names are case insensitive. On Linux they are case sensitive. Keep that in mind, if your application complains about missing tables.
And of course: Test this with backups only!
I need a single InnoDB database to be used by a Linux and a Windows MySQL installations (as I boot my PC to Linux or to Windows). Would be great if I could move the same database to a different PC. Importing/exporting data is hardly an option as the database is huge (over 4 GiB - easy to copy, but pretty long to export/import). How can this be achieved?
You should then install the MySQL database on the windows partition, and get the path to the database folder
In Linux, MySQL saves its data in "/var/lib/mysql/" so go there and create a symlink to the folder in the windows partition using the following command
ln -s /path/to/database/on/windows/ /var/lib/mysql/databasename
you need to be root to run this command, or use sudo.
This will make the MySQL server on both Operating systems see the same database folder.
NOTE: you should do some testing to check if this is a reliable solution, and if you are doing a mission critical project you should follow a more reliable setup.
I'm attempting (and failing) to upgrade MySQL on Mac OS X Server (Leopard) and running into trouble. Though the OS X Server docs say it's "normal" to have multiple versions of MySQL on your machine they don't go into any detail of how to "manage" them.
I have built and installed a newer version (5.1.40) than the original that Apple bundled (5.0.x).
Server Admin seems to manage only the initial (5.0.x) installation in /usr/bin
So I've STOPPED that version in Server Admin but can't get the new one (in /usr/local/mysql) to work.
Ideally I'd like to point the new version of mysql at the old database files in /var/mysql but not sure how...
Edit: Looks like my new MySQL is active (for some users anyway) but it's pointing to a different data file. It's pointing to /usr/local/mysql/data and I want it to point to /var/mysql
Admin user can connect but others get: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2). I'm assuming because this new database doesn't have those users enabled yet?!?! though I'd think I could still $ mysql -u root -p to it?!?
Anyone know how to manage this?
Well, I renamed the new MySQL's data directory to data.backup and then I created a symlink from where the new MySQL's data folder was to /var/mysql (where the old data file is) and so far so good... New version of MySQL is running and using the existing data file for its databases...
I'm not sure how to resolve your issue, but maybe you could trying using Homebrew or another OS X package manager to handle your software.
Will make upgrading in future a breeze.
EDIT: Sorry, just realized you are using OS X SERVER, I'm not familiar with it or if you should be using Homebrew on it.
