MySQL Workbench 5.2 goes GA – partial support for MySQL Cluster
Employee +7 Vote Up -0Vote Down

Configure MySQL Server nodes for MySQL Cluster

The new version of MySQL Workbench (5.2.25) has just gone GA – see the Workbench BLOG for details.

So what’s the relevance to MySQL Cluster? If you have a Cluster that uses MySQL Servers to provide SQL access then you can now use MySQL Workbench to manage those nodes:

  • Start & stop the mysqld processes
  • Configure the per-mysqld configuration data held in my.cnf or my.ini

The reason that I describe the support as ‘partial’ is that these MySQL Servers are treated as independent entities (no concept of them being part

Using Syslog with MySQL Cluster
Employee +3 Vote Up -0Vote Down

By default, MySQL Cluster sends log data to a file but you can also send it to the console or to Syslog; this article explains how to send it to Syslog. The example given here is for LINUX.

In this example, I’ll use the “user” syslog facility name and so the first step is to make sure that syslog is configured to route those messages. If this hasn’t already been configured then add the following lines to /etc/rsyslog.conf:

# Log user messages to local files
user.*    /var/log/user

For the changes to take effect, restart the syslog service:

[root@ws1 etc]# service rsyslog restart
Shutting down system logger:                               [  OK  ]
Starting system logger:                                    [  OK  ]

Note that you should make those changes as root.

Still as root,

Scaling Web Services with MySQL Cluster: An Alternative Approach to MySQL & memcached
Employee +6 Vote Up -0Vote Down

A new white paper is available from http://www.mysql.com/why-mysql/white-papers/mysql_wp_cluster_ScalingWebServices.php (http://www.mysql.com/why-mysql/white-papers/mysql_wp_cluster_ScalingWebServices.php" target="_blank)

MySQL and memcached has become, and will remain, the foundation for many dynamic web services with proven deployments in some of the largest and most prolific names on the web.

There are classes of web services however that are highly transactional and update-intensive, demanding real-time responsiveness and continuous availability. In these cases, MySQL Cluster provides the familiarity and ease-of-use of the regular MySQL Server, while delivering significantly higher levels of write performance with less complexity, lower latency and 99.999% availability.

This whitepaper will discuss the

Configure MySQL Enterprise Monitor to monitor MySQL Cluster
Employee +6 Vote Up -0Vote Down

MySQL Cluster 7.1 introduced the ndbinfo database which contains views giving real-time access to a whole host of information that helps you monitor and tune your MySQL Cluster deployment. Because this data can be accessed through regular SQL, various systems can be configured to monitor the Cluster. This post gives one example, extending MySQL Enterprise Monitor to keep an eye on the amount of free memory on the data nodes (through a graph) and then raise an alarm when it starts to run low – even generating SNMP traps if that’s what you need.

One of the features of MySQL Enterprise Monitor is that you can define custom data collectors and that those data
