MySQL Cluster on Windows - NDB API part 1 So you thought that just because MySQL Cluster 7.1 is GA on Windows that NDB API was available and you could just download the MySQL Cluster 7.1 binary for Windows and start hacking the NDB API. MySQL InnoDB Cluster – Setting up InnoDB Cluster on Windows. One of the most requested features for InnoDB cluster has been Windows support that we have now delivered as part of the InnoDB Cluster 5.7.17 Preview Rele ase 2. This blog post will show you how to get your InnoDB cluster running on your MS Windows 10 64bit system. We will run through the following steps. Nov 08, 2007  MySQL Cluster on Windows. Posted by: Alan David Date: September 12, 2006 02:45PM I need know the ETA (Estimated Time of Arrival) for MySQL Cluster on Windows. MySQL cluster for Windows is being intended by MySQL.com since the last year. I am not the first person requesting the ETA. Please give us to know. I need a course for my project. Installing MySQL Cluster Manager on Windows Platforms. To install MySQL Cluster Manager 1.1.6 on Windows platforms, you should first have downloaded the MSI installer file mcm-114-cluster-724-win32-x86msi (see Section 2.1, “Obtaining MySQL Cluster Manager”). Here is what I would do if I was forced into creating a cluster on Windows. Just so ya know it is not available through MySQL. Create two or three instances in ring replication, all of them master-slaving around the ring back to the original.

I want to create a MySQL NDB cluster on Hyper-V for testing so I have some questions in this regard.

1. Can I use Windows XP 32 bit? (because I already have a VM) If not then can I use Windows 7 or 10?
2. Do I only need one VM where both nodes will be installed (I don't know if MySQL supports multiple instances or something like that) or do I need at least two VMs?
3. I read that NDB cluster require load balancer. Can I do it without load balancer? I mean I will manually run statements (Insert/Update/Delete) on server1 to check if it goes to server2 or not instead of using some PHP application.
4. Do I need free version of MySQL or some enterprise version?
5. Do I only need MySQL or some other software also needed to setup cluster?

Can I use Windows XP 32 bit? (because I already have a VM) If not then can I use Windows 7 or 10?

You have the list of supported platforms here:http://www.mysql.com/support/supportedplatforms/cluster.html

From there I can see there are 32-bit binaries, and several windows versions, but check your specific combination. I would suggest not using 32-bit binaries/OS when possible for MySQL due to memory limitations, but you say it is

for testing

So I assume that for a small (< 2GB data) test that is ok?

Do I only need one VM where both nodes will be installed (I don't know if MySQL supports multiple instances or something like that) or do I need at least two VMs?

For production, 4 nodes are recommended. You can technically run it on 2 nodes -yes, you can run multiple instances of MySQL (and ndbd) on the same physical server, but again, you are doing a test, so depending which part you care to test more or less realistically it will work for you or not-. Network partitions and latency issues, and memory pressure will not show on a single (or just a few), small, machine test. Even for different VMs on the same physical server, you will not get a realistic scenario. But maybe you are not interested on that, and only on learning how to set it up and/or pure controlled switchover tasks.

I read that NDB cluster require load balancer. Can I do it without load balancer? I mean I will manually run statements (Insert/Update/Delete) on server1 to check if it goes to server2 or not instead of using some PHP application.

Yes, you can do that, but what is the point then, on having a cluster? You want 4 nodes at least (2 SQL and 2 data nodes you can crash at any time and have transparent failover). Why not set up a single Master-slave replication topology (Or master-master, with read only secondary master) in your case?

Do I need free version of MySQL or some enterprise version?

MySQL has a dual-license model. There is a community version of the NDB Cluster. It is free (no cost) but licensed under GPL, which means it has restrictions on how to use it (linked application must also be GPL). If you are an ISV or a developer shop that has some deliverables to clients, you may need to purchase an Enterprise licence. For testing, where you are not going to distribute the server or the application to anyone, you can use the Community edition. I am not a lawyer, read the license or hire one to read it for you.

Do I only need MySQL or some other software also needed to setup cluster?

Aside from really considering a load balancing solution (or integrate it on your application), for a production deployment I would say it is a must to have: a monitoring solution (providing trends and alerts), administration tools that make your life easier. Probably the most important part is someone to adapt your application- MySQL cluster is very different from a typical MySQL/InnoDB setup, and in most cases migrating to that is not transparent for how the application access it (it is more memory and key-value focused).

Here you have summary of differences between MySQL NDB Cluster and other similar concepts:

Once the MySQL Cluster executables and needed configuration files are in place, performing an initial start of the cluster is simply a matter of starting the MySQL Cluster executables for all nodes in the cluster. Each cluster node process must be started separately, and on the host computer where it resides. The management node should be started first, followed by the data nodes, and then finally by any SQL nodes.

1. On the management node host, issue the following command from the command line to start the management node process:

   The management node process continues to print logging output to the console. This is normal, because the management node is not running as a Windows service. (If you have used MySQL Cluster on a Unix-like platform such as Linux, you may notice that the management node's default behavior in this regard on Windows is effectively the opposite of its behavior on Unix systems, where it runs by default as a Unix daemon process. This behavior is also true of MySQL Cluster data node processes running on Windows.) For this reason, do not close the window in which ndb_mgmd.exe is running; doing so kills the management node process. (See Section 17.2.2.4, “Installing MySQL Cluster Processes as Windows Services”, where we show how to install and run MySQL Cluster processes as Windows services.)

   The required -f option tells the management node where to find the global configuration file (config.ini). The long form of this option is --config-file.

   A MySQL Cluster management node caches the configuration data that it reads from config.ini; once it has created a configuration cache, it ignores the config.ini file on subsequent starts unless forced to do otherwise. This means that, if the management node fails to start due to an error in this file, you must make the management node re-read config.ini after you have corrected any errors in it. You can do this by starting ndb_mgmd.exe with the --reload or --initial option on the command line. Either of these options works to refresh the configuration cache.

   It is not necessary or advisable to use either of these options in the management node's my.ini file.

   For additional information about options which can be used with ndb_mgmd, see Section 17.4.4, “ndb_mgmd — The MySQL Cluster Management Server Daemon”, as well as Section 17.4.26, “Options Common to MySQL Cluster Programs — Options Common to MySQL Cluster Programs”.

2. On each of the data node hosts, run the command shown here to start the data node processes:

   In each case, the first line of output from the data node process should resemble what is shown in the preceding example, and is followed by additional lines of logging output. As with the management node process, this is normal, because the data node is not running as a Windows service. For this reason, do not close the console window in which the data node process is running; doing so kills ndbd.exe. (For more information, see Section 17.2.2.4, “Installing MySQL Cluster Processes as Windows Services”.)

3. Do not start the SQL node yet; it cannot connect to the cluster until the data nodes have finished starting, which may take some time. Instead, in a new console window on the management node host, start the MySQL Cluster management client ndb_mgm.exe, which should be in C:mysqlbin on the management node host. (Do not try to re-use the console window where ndb_mgmd.exe is running by typing CTRL+C, as this kills the management node.) The resulting output should look like this:

   When the prompt ndb_mgm> appears, this indicates that the management client is ready to receive MySQL Cluster management commands. You can observe the status of the data nodes as they start by entering ALL STATUS at the management client prompt. This command causes a running report of the data nodes's startup sequence, which should look something like this:

   Commands issued in the management client are not case-sensitive; we use uppercase as the canonical form of these commands, but you are not required to observe this convention when inputting them into the ndb_mgm client. For more information, see Section 17.5.2, “Commands in the MySQL Cluster Management Client”.

   The output produced by ALL STATUS is likely to vary from what is shown here, according to the speed at which the data nodes are able to start, the release version number of the MySQL Cluster software you are using, and other factors. What is significant is that, when you see that both data nodes have started, you are ready to start the SQL node.

   You can leave ndb_mgm.exe running; it has no negative impact on the performance of the MySQL Cluster, and we use it in the next step to verify that the SQL node is connected to the cluster after you have started it.

4. On the computer designated as the SQL node host, open a console window and navigate to the directory where you unpacked the MySQL Cluster binaries (if you are following our example, this is C:mysqlbin).

   Start the SQL node by invoking mysqld.exe from the command line, as shown here:

   The --console option causes logging information to be written to the console, which can be helpful in the event of problems. (Once you are satisfied that the SQL node is running in a satisfactory manner, you can stop it and restart it out without the --console option, so that logging is performed normally.)

   In the console window where the management client (ndb_mgm.exe) is running on the management node host, enter the SHOW command, which should produce output similar to what is shown here: Free online titanic game.

   You can also verify that the SQL node is connected to the MySQL Cluster in the mysql client (mysql.exe) using the SHOW ENGINE NDB STATUS statement.
