cPanel is a very popular Linux hosting control panel, used not only by hosting providers but also enterprise and goverment bodies. For large scale hosting environments hosting mission critical databases, how do you integrate cPanel with a high availability database? 

In this blog post, we will show you how to integrate Percona XtraDB Cluster into cPanel to provide a high availability database hosting solution. By default, cPanel uses localhost to host the MySQL databases created by cPanel users. It is not uncommon to find MySQL to be the culprit when it comes to overloading the server. By having a remote MySQL server or cluster, we can offload some of the burden and increase the availability of other important services on the server.

Setting up a Galera cluster to integrate with cPanel requires you to meet the following requirements:

• skip-name-resolve must be turned OFF, as some cPanel services authenticate …

MySQL 5.7 comes with a new backup tool, named mysqlpump, which is almost the same as mysqldump with the ability of extracting data in parallel threads.

I tried a little experiment. Using a server containing 11 databases, with a total of 300 tables and about 20 million rows (roughly ≈ 10GB,) I used both mysqldump and mysqlpump to get a backup.

mysqldump --all-databases  > dump.sql

mysqlpump --all-databases \
    --add-drop-database --add-drop-table --skip-watch-progress \
    --default-parallelism=10 \
    --parallel-schemas=db,db1,db2 \
    --parallel-schemas=db3,db4,db5 \
    --parallel-schemas=db6,db7,db8 \
    --parallel-schemas=db9,db10 > pump.sql

The backup with mysqldump took 3 minutes and 33 seconds. The one with mysqlpump took 2 minutes and 55 …

It’s a pretty fair assumption that if your database is big enough and complex enough to produce metrics that warrant a monitoring system, it’s also complex enough to produce tons of data that are ultimately more distracting than relevant. It’s not unusual to look at a bevy of monitoring possibilities and feel overwhelmed, uncertain about where to center your focus. Of course, every database is different, but there are some fundamental truths you should consider when you ask yourself, “What should I monitor?” Some of these ideas might seem simple, but if you don’t keep these in mind, you’d be surprised how easy it can be to lose sight of the big picture.

Know Your Goal. What are you trying to achieve by monitoring in the first place? Ultimately, the real question of effective monitoring is, “What work is getting done?” Systems do work for you; the goal of monitoring is to make sure those systems are …

Last week, 21-23 September, it took place the European MySQL Conference, or “Data performance Conference” as this year’s subtitle was “MySQL. NoSQL. Data in the cloud.”. This year, it changed its location from London to Amsterdam and, as most people I talked to agreed, the change was for good. As every year, Percona was the company organizing it, but it had the participation of all the major players in the open source MySQL/MongoDB/Cloud data world. Special mention goes to Booking.com, which had more …

Hi all MySQL afficionados !

I just wanted to keep you informed that Fosdem’s organization opened the proposals for Devrooms.

As every year now, we submitted our participation. As soon as our devroom will be approved, the Call For Papers will be published.

Stay tuned for more information.

Cheers !

ARIN is the American Registry for Internet Numbers, the organisation that hands out the blocks IP addresses.

Each region has its own, for instance Australia/Pacific has APNIC. Naturally, they work very closely together.

Open Query can assist you with planning and deployment of IPv6 capabilities on your front-end servers, as well as at the back-end if you wish. Not all hosting providers support IPv6, but many good ones do. MySQL/MariaDB can operate in a native IPv6 or dual stack environment. Open Query enabled its own front-end servers for IPv6 a number of years ago already.

Query optimization can feel like an overwhelming task. Where to start? In this blog post, we’ll discuss how to select which queries you really should optimize. This is a step that’s often skipped, but shouldn’t be! Why is selecting the right queries to optimize so important? There are several reasons.

Penny-Wise, Pound-Foolish. Look at the forest, not just the trees, and optimize globally, not locally. If you’re optimizing a query that never causes a user-visible problem, doesn’t impact other queries, and doesn’t significantly load servers, you might be “optimizing” things that don’t matter, spending more money than you save. Your time has value, too! Keep in mind, too, that optimizing a query that generates only 1% of the database’s overall load will not be a significant benefit to the bottom line.

Whack-A-Mole Queries. It’s very common to find a slow query in a log file, try …

Database replication is vital enterprise technology but is dominated by inflexible, high-cost incumbents, especially in the case of Oracle. This webinar-on-demand introduces VMware Continuent replication and shows how it solves database replication problems in environments from bare metal to clouds.
