My first Cluster running on Windows @ Andrew Morgan’s MySQL Cluster Database Blog

My first Cluster running on Windows

Posted on June 16th, 2009 admin 50 comments

I figured that it was time to check out how to install, configure, run and use MySQL Cluster on Windows. To keep things simple, this first Cluster will all run on a single host but includes these nodes:
- 1 Management node (ndb_mgmd)
- 2 Data nodes (ndbd)
- 3 MySQL Server (API) nodes (mysqld)
Downloading and installing

Browse to the Windows section of the MySQL Cluster 7.0 download page and download the installer (32 or 64 bit).

MySQL Cluster Windows Installer

Run the .msi file and choose the “Custom” option. Don’t worry about the fact that it’s branded as “MySQL Server 7.0″ and that you’ll go on to see adverts for MySQL Enterprise – that’s just an artefact of how the installer was put together.

On the next screen, I decided to change the “Install to” directory to “c:\mysql” – not essential but it saves some typing later.

Go ahead and install the software and then you’ll be asked if you want to configure the server – uncheck that as we’ll want to tailor the configuration so that it works with our Cluster.

There are a couple of changes you need to make to your Windows configuration before going any further:
1. Add the new bin folder to your path (in my case “C:\mysql\bin”)
2. Make hidden files visible (needed in order to set up multiple MySQL Server processes on the same machine)
Configure and run the Cluster

Copy the contents of “C:\ProgramData\MySQL\MySQL Server 7.0\data” to “C:\ProgramData\MySQL\MySQL Server 7.0\data4″, “C:\ProgramData\MySQL\MySQL Server 7.0\data5″ and “C:\ProgramData\MySQL\MySQL Server 7.0\data6″. Note that this assumes that you’ve already made hidden files visible. Each of these folders will be used by one of the mysqld processes.

Create the folder “c:\mysql\cluster” and then create the following files there:

config.ini
```
[ndbd default]
noofreplicas=2
```
```
[ndbd]
hostname=localhost
id=2
```
```
[ndbd]
hostname=localhost
id=3
```
```
[ndb_mgmd]
id = 1
hostname=localhost
```
```
[mysqld]
id=4
hostname=localhost
```
```
[mysqld]
id=5
hostname=localhost
```
```
[mysqld]
id=6
hostname=localhost
```
my.4.cnf
```
[mysqld]
ndb-nodeid=4
ndbcluster
datadir="C:\ProgramData\MySQL\MySQL Server 7.0\data4"
port=3306
server-id=3306
```
my.5.cnf
```
[mysqld]
ndb-nodeid=5
ndbcluster
datadir="C:\ProgramData\MySQL\MySQL Server 7.0\data5"
port=3307
server-id=3307
```
my.6.cnf
```
[mysqld]
ndb-nodeid=6
ndbcluster
datadir="C:\ProgramData\MySQL\MySQL Server 7.0\data6"
port=3308
server-id=3308
```
Those files configure the nodes that make up the Cluster.

From a command prompt window, launch the management node:
```
C:\Users\Andrew>cd \mysql\cluster
C:\mysql\cluster>ndb_mgmd -f config.ini
2009-06-16 20:01:20 [MgmSrvr] INFO     -- NDB Cluster Management Server. mysql-5.1.34 ndb-7.0.6
2009-06-16 20:01:20 [MgmSrvr] INFO     -- The default config directory 'c:\mysql\mysql-cluster' does not exist. Trying to create it...

2009-06-16 20:01:20 [MgmSrvr] INFO     -- Reading cluster configuration from 'config.ini'
```
and then from another window, check that the cluster has been defined:
```
 C:\Users\Andrew>ndb_mgm
-- NDB Cluster -- Management Client --
ndb_mgm> show
Connected to Management Server at: localhost:1186
Cluster Configuration
---------------------
[ndbd(NDB)]     2 node(s)
id=2 (not connected, accepting connect from localhost)
id=3 (not connected, accepting connect from localhost)
```
```
[ndb_mgmd(MGM)] 1 node(s)
id=1    @localhost  (mysql-5.1.34 ndb-7.0.6)
```
```
[mysqld(API)]   3 node(s)
id=4 (not connected, accepting connect from localhost)
id=5 (not connected, accepting connect from localhost)
id=6 (not connected, accepting connect from localhost)
```
Fire up 2 more command prompt windows and launch the 2 data nodes:
```
C:\Users\Andrew>ndbd
2009-06-16 20:08:57 [ndbd] INFO     -- Configuration fetched from 'localhost:118

RWPool::init(a2, 52)
WOPool::init(21, 5)
```
(repeat from another new window for the second data node).

After both data nodes (ndbd) have been launched, you should be able to see them through the management client:
```
ndb_mgm> show
Cluster Configuration
---------------------
[ndbd(NDB)]     2 node(s)
id=2    @127.0.0.1  (mysql-5.1.34 ndb-7.0.6, Nodegroup: 0, Master)
id=3    @127.0.0.1  (mysql-5.1.34 ndb-7.0.6, Nodegroup: 0)
```
```
[ndb_mgmd(MGM)] 1 node(s)
id=1    @127.0.0.1  (mysql-5.1.34 ndb-7.0.6)
```
```
[mysqld(API)]   3 node(s)
id=4 (not connected, accepting connect from localhost)
id=5 (not connected, accepting connect from localhost)
id=6 (not connected, accepting connect from localhost)
```
Finally, the 3 MySQL Server/API nodes should be lauched from 3 new windows:
```
C:\Users\Andrew>cd \mysql\cluster
C:\mysql\cluster>mysqld --defaults-file=my.4.cnf

C:\Users\Andrew>cd \mysql\cluster
C:\mysql\cluster>mysqld --defaults-file=my.5.cnf

C:\Users\Andrew>cd \mysql\cluster
C:\mysql\cluster>mysqld --defaults-file=my.6.cnf
```
Now, just check that all of the Cluster nodes are now up and running from the management client…
```
ndb_mgm> show
Cluster Configuration
---------------------
[ndbd(NDB)]     2 node(s)
id=2    @127.0.0.1  (mysql-5.1.34 ndb-7.0.6, Nodegroup: 0, Master)
id=3    @127.0.0.1  (mysql-5.1.34 ndb-7.0.6, Nodegroup: 0)
```
```
[ndb_mgmd(MGM)] 1 node(s)
id=1    @127.0.0.1  (mysql-5.1.34 ndb-7.0.6)
```
```
[mysqld(API)]   3 node(s)
id=4    @127.0.0.1  (mysql-5.1.34 ndb-7.0.6)
id=5    @127.0.0.1  (mysql-5.1.34 ndb-7.0.6)
id=6    @127.0.0.1  (mysql-5.1.34 ndb-7.0.6)
```
Using the Cluster

There are now 3 API nodes/MySQL Servers/mgmds running; all accessing the same data. Each of those nodes can be accessed by the mysql client using the ports that were configured in the my.X.cnf files. For example, we can access the first of those nodes (node 4) in the following way from (yet another) window:
```
C:\Users\Andrew>mysql -h localhost -P 3306
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2
Server version: 5.1.34-ndb-7.0.6-cluster-gpl MySQL Cluster Server (GPLType 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> use test;
Database changed
mysql> create table assets (name varchar(30) not null primary key, value int) engine=ndb;
Query OK, 0 rows affected (1.44 sec
mysql> insert into assets values ('car', 950);
Query OK, 1 row affected (0.00 sec
mysql> select * from assets;
+------+-------+
| name | value |
+------+-------+
| car  |   950 |
+------+-------+
1 row in set (0.00 sec
mysql> insert into assets2 values ('car', 950);
Query OK, 1 row affected (0.00 sec)
```
To check that everything is working correctly, we can access the same database through another of the API nodes:
```
C:\Users\Andrew>mysql -h localhost -P 3307
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2
Server version: 5.1.34-ndb-7.0.6-cluster-gpl MySQL Cluster Server (GPL)
```
```
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
```
```
mysql> use test;
Database changed
mysql> show tables;
+----------------+
| Tables_in_test |
+----------------+
| assets         |
+----------------+
1 row in set (0.06 sec)
```
```
mysql> select * from assets;
+------+-------+
| name | value |
+------+-------+
| car  |   950 |
+------+-------+
1 row in set (0.09 sec)
```
It’s important to note that the table (and its contents) of any table created using the ndb storage engine can be accessed through any of the API nodes but those created using other storage engines are local to each of the API nodes (MySQL Servers).

Your next steps

This is a very simple, contrived set up – in any sensible deployment, the nodes would be spread accross multiple physical hosts in the interests of performance and redundancy. You’d also set several more variables in the configuration files in order to size and tune your Cluster. Finally, you’d likely want to have some of these processes running as daemons or services rather than firing up so many windows.

It’s important to note that Windows is not a fully supported platform for MySQL Cluster. If you have an interest in deploying a production system on Windows then please contact me at andrew@clusterdb.com

  Hi
  i tried this out.seems that the cluster is working, but when i am accesing it using mysql -h localhost -p 3307 . it asks for a password and when i give the previous password it shows
  “access denied for user odbc@localhost.
  what i did is that i unsinstalled the previous version of mysql 5.1. and then installed the mysql cluster. but it did not asked me for giving any password .
  Please suggest how to go with it?
- admin August 5th, 2009 at 10:36
  
  Have you made sure that permission has been granted for ‘odbc’@'localhost’? Try logging in with ‘mysql -u root’ to check and fix if needed.
- Siddharth Prasad August 6th, 2009 at 05:35
  
  hi it’s working..now . but how can i deploy it on other systems , so that i can use it from other systems…….how to get the more broader version of this….
  please Reply…

  hi Andrew.
  i have some problem while making the data node on other system.when i configure all the files on my management node as described by the “DEPLOYING MYSQL CLUSTER OVER MULTIPLE HOST ON LINUX” .I am just extending it to windows.if use your example every thing is working fine…but when i make the data node on other system without making it as management node.when i issue the ndbd command…. it’s not able to identify the management node…
  I am not getting it…Can you please help me..
  it’s necessary….

  Hi Siddharth,
  
  are you specifying the correct IP address and port number (e.g. ndbd –initial -c 192.168.0.3:1186).
  
  What error message did you get?
  
  Regards, Andrew

  Hi Andrew,
  Thanks for the Reply..Now it’s working..
  i just have to give the managment node ip with the NDBD command and in the sql node Configuration file i just have to mention one more parametre called ndb-connectstring 192.168.1.8 the ip of the managment node…..
  but every time i start my cluster i have to open like many command prompt windows…how to avoid this?
  
  And Can you name some good resources about managing and using the cluster configuration?
  
  Thanks

  Hi Andrew
  there is a problem …when i start more than 4 data nodes . and use the
  shell: ndb_mgm show command to see the status of the server.it says cannot get configuration,illegal reply from server..and the managment server crashes..
  
  i searched the net and found that windows
  ” On Windows, the internal basestring_vsprintf() function did not return a POSIX-compliant value as expected, causing the management server to crash when trying to start a MySQL Cluster
  with more than 4 data nodes.”
  
  it will be nice of you,if you can help me out of this.
  
  Thank you

  Hi Siddharth
  You can pick up the fix by following the instructions in the bug report…. http://bugs.mysql.com/bug.php?id=45733
  
  Alternatively, you could wait for MySQL Cluster 7.0.7
  
  Regards, Andrew.

  Hi Andrew
  sorry to disturb you again.
  This time the problem is of speed.with 7 lacs records in a table A group by and order by sql query takes 32 secs to give the reply.
  
  when i took the back up and executed it on other machine without clustering and with engine=innodb . that also takes approx 35 secs.
  
  is it OK . or my clustering is not working .
  i have a four data node , with 2 replica, 2 node group and 6 sql node clustering.
  
  if it’s not ok what should i do? Waiting for the Reply.
  
  Thank You

  Hi, thanks for the great post, it helped me alot setting up my first cluster on Windows. I’ve got the cluster up and running but are now faced with a stability problem, it seems that “a little now and then” my datanodes simply shut down for no apparent reason. The shutdown is not synched though and it could well be that only one datanode shut down while the other (on a different server) keep running. This would be expected if I had any connection issues and one datanode lost contact with the management node and the other node, but as far as I can see there are no connection issues here. Do you know how I can proceed to find out what’s going on?
- admin August 23rd, 2009 at 08:47
  
  Hi Erik,
  
  the first thing to check would be the log files – you should be able to recognise from the log files which data node each belongs too.
  
  Once you’ve had a look and there’s no obvious cause from your side then search bugs.mysql.com to see if your problem has been raised before and then raise it if not.
  
  Note that Windows is still considered a development-only platform for MySQL Cluster but bug reports are still gratefully received as that will help to bring it up to production level.
  
  Regards, Andrew.

  hi AndRew,
  
  in this step: Copy the contents of “C:\ProgramData\MySQL\MySQL Server 7.0\data” to “C:\ProgramData\MySQL\MySQL Server 7.0\data4″
  
  I try to find data directory in “C:\ProgramData\MySQL\MySQL Server 7.0″ and “C:\Program Files\MySQL\MySQL Server 7.0″ but don’t have anything.
  
  Please help me.
  Thanks.

  LanhVC,
  
  did you first make sure that you’ve set up Windows to make hidden files visible?
  
  Regards, Andrew.
- Kelvin August 26th, 2009 at 09:16
  
  I just tried to follow the instructions to create the cluster. After I typed ndbd, I got the errors:
  Error setting NTFS compression attribute: 6
  Error setting NTFS compression attribute: 6
  Error setting NTFS compression attribute: 6
  Error setting NTFS compression attribute: 6
  Error setting NTFS compression attribute: 5

  Do you have any ideas how to solve this?
  
  Thanks a lot

  Hi Kelvin,
  
  There’s a patch available (http://bugs.mysql.com/bug.php?id=44418) or you can wait for MySQL Cluster 7.0.7 binaries to be published or download the source from ftp://ftp.mysql.com/pub/mysql/download/cluster_telco/mysql-5.1.35-ndb-7.0.7/ and compile it for yourself.
  
  Regards, Andrew.
- Kelvin August 27th, 2009 at 02:12
  
  Hi, Thanks for your reply. I downloaded from the link provided but need to search for the tutorial on how to compile it in windows as I’ve never done this before.

  I’ve had the same problem and I fixed it. It was because I didn’t install the MySql Administrator wizard. And then restart your machine.

  Hi Alex,
  
  I’ll be experimenting more on Windows soon – I’ll let you know if I seem anything similar.
  
  Have you tried the suggestion from Xavi?
  
  If that doesn’t help then I’d suggest searching bugs.mysql.com to see if anyone has raised a similar issue and create a bug report if they haven’t.
  
  Andrew.

  Something has recently changed in Cluster that meant that the mysqld processes wouldn’t connect to the Cluster. I’ve now replaced “ndbcluster=true” with just “ndbcluster” in the my.X.cnf files and it should now work again.

  Hi Andrew,
  
  Currently i am using different hosts for my SQL nodes. However, they do seem to work when i fire them to start. I have tried alot of method but it just didnt work.
  
  this is my my.cnf file on the different machines:
  
  [mysqld]
  ndbcluster
  ndb-connectstring=xxx.xxx.42.158
  datadir=”C:\…\data”
  port=3306
  server-id=3306
  —————————————
  this is my config.ini:
  [ndbd default]
  NoOfReplicas=4
  
  [ndb_mgmd]
  id=1
  hostname=xxx.xxx.42.158
  
  [ndbd]
  id=19
  hostname=xxx.xxx.178.197
  
  [ndbd]
  id=20
  hostname=xxx.xxx.12.195
  
  [ndbd]
  id=21
  hostname=xxx.xxx.178.197
  
  [ndbd]
  id=22
  hostname=xxx.xxx.17.234
  
  [mysqld]
  [mysqld]
  [mysqld]

  I cannot find the .msi file
  where is it??
  I searched the whole folder
- admin March 6th, 2010 at 12:00
  
  Hi Mayank,
  
  the MSI file will reappear soon. There has been a re-org of the MySQL site. For Windows go to dev.mysql.com and then get the Windows zip file from the “development” tab of the Cluster downloads page.
  
  Take a look at http://www.clusterdb.com/mysql-cluster/running-mysql-cluster-over-multiple-servers/ to see how to install MySQL Cluster from the zip file.

  Hi Andrew
  
  I am using mysql-cluster-gpl-7.1.2a-beta-win32.zip version of MySQL Cluster.
  
  I prepared the config.ini file but when I ran ndb_mgmd command, it is showing the following error:
  
  C:\mysql\cluster>ndb_mgmd -f config.ini

  Hi Andrew
  
  I resolved this above issue of “config.ini” file read error by saving the file with Converter type as “default” in the file editor.
  
  Now, the following processes are running as expected as discussed in the article “My first Cluster running on Windows”
  
  (1) ndb_mgmd
  
  (2) nbd_mgm
  
  (3) ndbd
  
  (4) ndbd
  
  When I try to start the mysqld with the following commands,
  
  C:\mysql\cluster>mysqld –defaults-file=my.4.cnf
  
  C:\mysql\cluster>mysqld –defaults-file=my.5.cnf
  
  C:\mysql\cluster>mysqld –defaults-file=my.6.cnf
  
  these commands make the processes to stay for two seconds and it exits by itself.
  
  So, it is not shwoing any error messages also but in the ndb_mgmd console shows the following log messages:
  
  reserved_nodes 1 and 4.

  Hi Andrew
  
  With respect to the above issue, following are the errors shown when I try to use the mysql client in the same desktop
  
  C:\mysql\mysql-cluster>mysql -h localhost -P 3306
  ERROR 2003 (HY000): Can’t connect to MySQL server on ‘localhost’ (10061)
  
  C:\mysql\mysql-cluster>mysql -h localhost -P 3307

  C:\mysql\mysql-cluster>mysql -h localhost -P 3308

  Please help in resolving this above issues

  Hi Anbu,
  
  have you used the Windows task manager to check if the mysqld processes are running? If so, try substituting ‘localhost’ with 127.0.0.1.
  
  Andrew.
- admin April 20th, 2010 at 17:56
  
  Anbu, Have you checked all of the error log files for more hints?
  
  Regards, Andrew.
- Anbu April 21st, 2010 at 14:06
  
  Hi Andrew
  
  I have replaced the ‘localhost’ text with ’127.0.0.1′ and I ran the ndb_mgmd, but there is no effect in the mysqld process execution. It has the same behavior as mentioned above.
  
  Yes, I have used the Task Manager only to verify the processes running.
  
  When I verified the mysqld error log file as mentioned by you, I am seeing the following error in it.
  
  mysqld: Table ‘mysql.plugin’ doesn’t exist
  100421 19:27:48 [ERROR] Can’t open the mysql.plugin table. Please run mysql_upgrade to create it.
  100421 19:27:48 InnoDB: Started; log sequence number 0 44233
  100421 19:27:49 [Note] NDB: NodeID is 4, management server ‘localhost:1186′
  100421 19:27:49 [Note] NDB[0]: NodeID: 4, all storage nodes connected
  100421 19:27:49 [Note] Starting Cluster Binlog Thread
  100421 19:27:49 [ERROR] Fatal error: Can’t open and lock privilege tables: Table ‘mysql.host’ doesn’t exist
  
  I have verified the MySQL forums to resolve these issues. They are describing that the MySQL System Table are not available properly and need to recreate them. For this, we need to execute the following commands
  
  mysql_install_db
  mysqld_safe
  
  To run the first command, I need to execute the perl script file provided in the scripts folder but it is expecting that the MySQL Server should be installed in the following folder
  
  C:\Program Files\MySql\MySQL Server 5.1
  
  As per our initial discussion in the article, the mysql cluster should be installed in the following folder
  
  c:\mysql
  
  Please send your suggestion to resolve this issue of not starting the mysqld processes.
  
  Advance Thanks

  Hi Andrew,
  I have installed mysql-cluster-gpl-7.1.3 on my desktop.
  Everything is working fine , except sqld
  I have created a directory C:\ProgramData\MySQL\MySQL Server 7.1.3\data4, then similarly data5 and data6 folders.
  I then created in C:\mysql\cluster my.4.cnf, my.5.cnf and my.6.cnf as mentioned in the above steps.
  Following is what I have mentioned in the my.4.cnf file :-
  [mysqld]
  ndb-nodeid=4
  ndbcluster=true
  datadir=”C:\ProgramData\MySQL\MySQL Server 7.1.3\data4″
  port=3306
  server-id=3306
  
  Then I executed
  mysqld –defaults-file=my.4.cnf from the command prompt and it gave me an error
  
  [ERROR] Can’t find messagefile ‘C:\mysql\share\english\errmsg.sys’
  
  Later I created the folder hierarchy as shown above and created a empty text file errmsg.sys
  I again executed the
  mysqld –defaults-file=my.4.cnf from the command prompt and it gave me an error
  [ERROR] Can’t read from messagefile ‘C:\mysql\share\english\errmsg.sys’
  What could be the problem?
  Thanks in advance.

  Hi Rajendra,
  
  one fix I can see – replace “ndbcluster=true” with just “ndbcluster”.
  
  Andrew.
- admin April 29th, 2010 at 08:23
  
  Hi Anbu,
  
  on Windows, I don’t use the mysql_install_db script (as I haven’t gone to the trouble of installing Perl); instead, I just copy the contents of the mysql database that came with the installation. This is described in the above blog entry.
  
  Regards, Andrew.
- Manik May 11th, 2010 at 11:05
  
  Hi Andrew,
  
  I am getting the same error as Rajendra. But i used “ndbcluster” directly.
  
  Can you please give me a guideline.
  
  thanks in advance

- admin May 19th, 2010 at 16:13
  
  Hi Manik,
  
  try including the MySQL installation base directory explicitly when you start the MySQL Server. e.g.
  
  mysqld –basedir=”c:\Program Files\mysql …..”
  
  If this doesn’t work, try using the ZIP file rather than the MSI installer – as explained in http://www.clusterdb.com/mysql-cluster/running-mysql-cluster-over-multiple-servers/
  
  Regards, Andrew.
- Manik May 24th, 2010 at 14:14
  
  thanks admin.
  it now working.
  i used the zip file.

  Got my cluster up and running.
  I would be interested to see –
  
  1. How I can run the nodes and the management server in the form of services
  
  2. Or an alternate way by which I don’t have to manually run the command to start the nodes ..
  
  Regards,
  Sammy Lamba
- admin June 7th, 2010 at 10:30
  
  Hi Sammy,
  
  running as a service isn’t there today but it’s something that’s being worked on.
  
  Regards, Andrew.
- Md. Mijanur Rahman June 14th, 2010 at 18:25
  
  Sir, when I wanna access the first node, it asks me for a password and I don’t know where from I’d get the password as I’m a beginner.
  And whats the name of the second data node other than ndbd. I’m waiting for your help.
