Is there any working solution for MySQL to be able to request data directly via HTTP/jsonp way?
I need to provide ready SQL statement to the server.
Something with SQL-templates etc.
There is beta version of mysql 5.7 that does that
MySql experimental MySQL HTTP API
I am currently trying the following alternatives:
YOG-Sql Tunnel in PHP and
Others: (1) undergo writing some webservices (java - php - c), (2) use 'mysql proxy' or 'mysql tunnel' (3) Code everyhing in gcc and run a proxy as http.
Tried many, stayed with YogSQL Tunnel (lot easier) - BTW ALL THOSE DID NOT GAVE SAME REAL-TIME RESULTS AS EVERYTHING INSIDE THE SAME DATACENTER (2 servers) or a gigabit network (250k - 500k records/second). So, latency may be a killer on one's ubiquitous cloud computing.
No, there is no way to do this.
I tried NGINX http add-on modules
ngnix really rocks, on static html even amazon free was outstanding (1ms wait) on 3000 requests/sec. Specific SQL modules, whatsoever, may be memory-consumig if goes heavy loader.io.

I am using MySQL workbench on windows, which I want to connect to a Node-Red running on the IBM cloud. Since I don't run them on the same server the host 127.0.0.1 and port 3306 does not seem to work. What permissions should I give?
I'm going to make a LOT of assumptions here, because there really isn't enough information in your question.
First assumption, by "running on IBM" you mean that Node-RED is running on the IBM Cloud hosting service.
The short answer is you can not do what you want.
The longer version is that you probably could actually make this work but doing it is a REALLY bad idea.
Second assumption, you are doing this from home (even if you are doing it from a office location the same problems are likely to apply). This means you are connected to a local LAN using RFC 1918 address range (e.g. 192.168.0.x), this means you are behind a router that is performing NAT (Network Address Translation). This means you are going to need to set up portforwarding on the router so that when traffic arrives at the router it will send it on to your Windows machine. How you do this will depend on your router.
Next problem, your broadband probably doesn't have a static IP address which means it will change every time your connection drops. There are work arounds for this using things like Dynamic DNS. But that's too complicated to get into here.
Assuming you get all of that sorted out you still have the problem that you have now exposed your mysql database to the internet, so you need to make sure you have enabled all the right security measures to prevent people logging in and at best seeing all your data.
There are 2 much better solutions to this
Run Node-RED on the same machine or at least on the same local network as the database.
Use one of IBM Clouds hosted database solutions, these are a lot easier to connect to a IBM Cloud instance of Node-RED.
If you do not want to open ports to your network I recommend using a free MYSQL remote server
A simple website is https://remotemysql.com
Just take the screenshot of the credentials of your database after registration.
Keep in mind if your database is empty it will get deleted after some time.
I am working in a project where we are using Go as a web server and MySQL.
We have been told to implement fault tolerance to handle a hardware crash. We were given 2 servers which have MySQL and the Go-server on them.
We have succesfully set up replication in MySQL, but we are struggling with the failover part. Our thought was to get an extra server with HAProxy to have a primary server and then being able to failover to the backup server.
We also considered using MySQL failover, but did not see how we could redirect the traffic using it.
Is this a reasonable plan? Or what would you recommend that we do instead?
If you want two identical servers connecting to their local MySQL instances, you need a way of deciding which one is the production server. There are a number of solutions for that, including
Setting up a reverse proxy, as you mention, but then, your proxy
itself becomes a SPOF,
Using a floating IP, also known as a failover
IP, but this only works if your host supports it. Cloud providers
typically support them, as well as some bare metal server providers.
There is nothing specific to Go as far as I know.
I client of ours did a PCI scan on their site and came up with the following alert:
vulnerable MySQL version: 5.5.36---Risk Level High
Is this version of MySQL in fact more vulnerable than others? Do I need to update the version (which will affect all the sites on the server) or can I tell him otherwise?
If an external scan is detecting MySQL, you've got huge problems. You need to firewall that service immediately.
You should not have port 3306 open to the general public under any circumstances, especially not if you're trying to get PCI compliance.
Firewall this service completely. If other external servers need access to this, they should do so via a VPN or SSH tunnel. Where this isn't practical, you must employ IP whitelisting at the firewall level.
The threat is real, but it's only in the client:
CVE-2014-0001
That doesn't just mean the command-line client, but any client, such as the MySQL API via PHP, etc.
If your MySQL client library only connects to your server, then there's no threat, as long as your server isn't exploited.
Still, you're unlikely to pass a PCI audit until you update MySQL beyond that version. You should be able to update to the latest 5.5 easily.
I want to configure mysql proxy on my test environment to observe the below.
1. Behavior of the proxy
2. How load, CPU usage varies on my test server for read/write distribution.
I googled and able to install proxy on my ubuntu linux.
But I didnt see any thing on configuring it in a step by step manner and how to start or stop this.
Shall some one explore on this and this would be of great help for me.
Thanks in advance

By default if you run the proxy on the same machine as the server it will listen to port 4040 and query a backend server on the msyql default port of 3036. Other port numbers and server locations can be configured from the command line or with a configuration file.
To distribute queries across servers, add monitoring, profiling etc. you need to provide a Lua script to mysql-proxy. See the example / tutorial scripts in /usr/local/share/docs that came with the installation download. There is work to do for a production implementation.
The basics of how the scripting works can be found here under MySQL Proxy Scripting.
Don't be worried about Lua. The syntax is quite readable given the tutorial examples to work from. As and when you need it lua.org has more details of Lua.
Are there any database only hosting services?
I need a MySQL only hosting service but I couldn't find any. All mysql hostings are part of a package e.g. PHP + MySQL.
I need it for development purposes. Having my PHP files somewhere else I can remotely connect to this mysql server and once an application is ready I can put that on a server having both PHP + MYsql. [well, there a some reason to have this kinda setup, if you have something to suggest please do.]
Any suggestion/recommendation if you have used any.
Thanks
The problem with a database-only host would be the security. The database need to be accessed over the Internet, thus username and password to access it are sent over the Internet. Even though you could add encryption and other protection, there's still a risk that the security is breached.
In general, you should never allow direct access to databases over the Internet! It's a real bad practice, which also explains why it's hard to find.
One way to get around such limitation is by building a web service around your database. In this web service you'll add all the functionality that you need to apply on this database, and the web service itself will keep the database itself protected. There would still be a risk that your web service gets compromised but even in that case, the attacker could never do more damage than the specific web service allows.
Such a web service can be created in PHP, although I myself have more experience with doing something similar with .NET and C# on SQL Server...
I think that you can find hosts with MySQL and PHP cheap enough that it would be easiest for you just to use one of those hosts and only use what you need.
Web Hosting Buzz has a plan for $5.95 (a month) which has unlimited databases, 400GB storage, and 500GB/Month data transfer.
A few weeks after the question was posted, Amazon announced a beta of "Amazon Relational Database Service (Amazon RDS)." It acts like MySQL 5.1.

Seems pricey for what you want, but you never said you were the one who would be paying the bill.
Contract a dedicated server.
Use it only to host your MySQL database
If the server is managed, they should help you with basic MySQL problems as it is usually preinstalled. I use http://www.hostingmatters.com/
If you are just needing this for developement purposes for PHP + MySQL why not just install EasyPHP (http://www.easyphp.org/). This installs quickly and easily and I think it's great for developement.
I've had no problems installing additional PEAR extensions and such after the fact with this.
There's a free option on Heroku and paid options up from there: https://addons.heroku.com/cleardb
