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.

I'm a beginner in SQL so i'm sorry if the question is too basic.
I just created a database in MySQL Workbench in my computer and i would like to be able to access and modify the database from another computer within my house. I read some solutions but they all require using some external product, is there a way and how can i do this by the MySQL Workbench GUI, or maybe other functionalities from MySQL?
I also installed MySQL community server on the other computer that i would like to connect my database to.
Thanks!
If it's a home network, and both of you are connected via same router, then you can connect to mysql server on the other device using http://ip_of_machine_running_mysql:3306.
ip_of_machine_running_mysql should be the ip of the machine running mysql server.
Worth to note that you need to allow remote connection to mysql if you haven't already done so when you were doing mysql installation.
The steps for enabling remote access differs for your os(windows, ubuntu, mac), but you can easily find tutorials and how to's for changing such configuration.

I have been using MySql Workbench to connect to a local MySql server and to remote MySql Servers. The last couple of days the Workbench freezes when I connect to the local version. It still works for the remote servers.
I am using workbench 6.3.4 and then tried 6.2.5 just to see if it is a version issue.
I also can access the local MySql instance using HeidiSQL.
Any recommendations on what to look for?
Update
The advice to recreate the connection solved the issue. I just created a new one and it works fine.
A couple of things you can try:
Try restarting the sql server (remember, workbench is just a utility for accessing a db, it does not host the database for you)
See if you can access mysql on the command prompt / terminal, the command for mac & windows
(once you navigate to the mysql folder, try the command:)
mysql -u root
(if you have a password-protected account, the command will be
mysql -u someuser -p
If the above doesn't work, mysql is either offline or denying you access (depending on response), and you'll need to setup the server / assign privileges.
If all else fails, it may help to try another version of SQL / Workbench (for a easy-to-use sql sever setup, I'd recommend WAMP or MAMP, assuming you want a HTTP server bundled with it)
Additionally, it may help to recreate the local connection in workbench (of if your getting regular crashes, reinstall & update workbench). Good luck with it.
I know the question I am about to ask is a very stupid once but I am new to MYSQL so please bear with me. Want I want to do is create a database on my local machine and also access/manipulate it from their. I thought MYSQL WB was the all in one tool to do this i.e it will also allow me to create a database and also make a MYSQL server from which to access it. But I came to know the Workbench is just a front end and you need to have a some kind of a seperate MYSQL server module for it to access.
The problem is I can't seem to find any link for a simple a server module on the MYSQL download site.
http://dev.mysql.com/downloads/ .
It has one Cluster Server but I don't think this is what I am looking for. If anyone could provide a link to the MYSQL server module using which I could connect MYSQL Workbench on my local host, and the steps to connect them that would be great.
The one your looking for is named MySQL Community Edition. The current version is 5.6.14. Just select your platform (mac, linux or windows) and follow the installation guide.
If you wish to have php/mysql then you can download xampp. It includes all the necessary tools. Or if you wish to install it separately then follow this for Windows,
http://dev.mysql.com/downloads/installer/
I'm trying to get back into PHP and MySQL development since i've found out that MySQL now allows stored procedures. I work with these at work on an Oracle database and use PL/SQL developer to create them. I was looking for a similar sort of interface for MySQL and was pointed in the direction of MySQL workbench. I'm using Xampp as my test server setup and would like to link MySQL Workbench to MySQL on this server however I'm stuck at one of the stages in the installation. I'm trying to create a new server instance and have been successful as far as testing the database connection however on the next page it asks me to set the 'windows configuration parameters' for this machine and failes to discover a MySQL service. I have ensured that both the Apache server and MySQL services are running in Xampp but do not understand why a MySQL service cannot be found and is not being displayed. Has anyone else encountered this issue when trying to use MySQL Workbench and if so, how did you amanage to get it up and running? I'm using Windows 8 and don't know if this is the reason a service isn't being found. I apologise if this is a really simple question with a simple answer however I have only ever used PHPMyAdmin before which is relatively simple to setup.
I have found problems with the packaged *AMP systems. They don't always install things the way other applications expect. e.g. The MAMP system doesn't work well with Python. it's quite easy to install each of Apache, PHP and MySql on Windows (and two of them are already on the Mac and Linux)
If you use the standard MySql install you should have no trouble installing the Workbench, I've done it on both Windows and Mac.
I have found it a bit flakey at times, it won't connect to older server versions and tends to crash when running long scripts. It also doesn't have a great UI for queries, A good program like PLSQL Developer to TOAD would be nice.
The service detection is rather simple. It expects that the service contains "MySQL" in its name. This is planned to be improved later. For now rename your service to something like "MySQL Xampp".
I am extremly new with databases. I have only created one, and that was in SQLite on android. I downloaded MySQL Admin for linux (Ubuntu) and downloaded and installed Admin. Now I want to create a database, but I jave know idea what I'm doing. I created a connection via the drop down menu option 'Open Connection Editor', and I keep getting a 'MySQL Error Nr. 2005' error. Do I have to do something command line wise first to set up the database?
Any help is appreciated.

MySQL is different to SQLite in that you need to have some server software running the whole time managing the database. It's that server software that you connect a MySQL client to.
You need to grab yourself a copy of MySQL Server then I'd recommend this tutorial
Good luck!
If you are using Ubuntu you can install MySQL Server easily with this command:
sudo apt-get install mysql-server
and then I suggest you to download MySQL Workbench, it's a GUI Tool where you can do almost everything with MySQL databases (create,drop,alter, modeling, administer the service).
Then, you can create a connection with mysql workbench or mysql admin (or another client) and do your stuff. If you installed the server in your PC then the parameter are something like this:
host = localhost
user = root
password = (the password you specified in the installation)
