This article outlines the procedure for replacing the native MySQL®️ or MariaDB®️ service that is preinstalled on any typical Plesk Onyx 11 CentOS 7 server. The procedure outlines removal of the existing MySQL related binaries and replaces them with an adequate version of the Percona binaries. Once these Percona binaries are in place, a typical multistage MySQL Incremental version upgrade is processed to bring the existing databases and Percona binaries to the desired Percona 5.7 version.

We recently posted an article on Upgrading MariaDB 10.0 to 10.3.9 on Ubuntu 16.04. We are now going to provide insight on upgrading MariaDB 10.0.X to 10.3.X on a CentOS 7 server. Continue reading “Update MariaDB from 10.0 to 10.3 on CentOS 7”

Often this is the result of competing redirects, one trying to force HTTPS (SSL) and another redirecting back to HTTP (non-SSL), or between www and non-www forms of the URL.
MariaDB is quickly becoming the de facto open-source database software to use in development, production, and even enterprise environments. Our very own Cloud Sites product uses the newest in MariaDB as it’s mostly known for being a fork and drop-in replacement to MySQL, which is created and maintained by the original MySQL developers.
As discussed earlier in our MySQL Performance series, the InnoDB storage engine is designed to be a high-performance database for very large datasets. The row-locking technique it uses allows for many read and write requests to occur on a single table concurrently. This is a vast improvement in speed over traditional Continue reading “MySQL Performance: InnoDB Buffers & Directives”
The majority of work needed when adjusting the MySQL server is editing the applicable directives within a MySQL configuration file. There are multiple, optional configuration files that MySQL looks for when starting up. They are read in the following order: Continue reading “MySQL Performance: System Configuration File & Routine Maintenance”
As we explored in our previous article of our MySQL Perfomance Series: MySQL vs. MariaDB there are very few downsides to using MariaDB over standard MySQL. Our high-availbility MariaDBs have proven itself to be a worthy successor with easily migitated drawbacks. As the last article in our series we will focus on upgrading to various MySQL and MariaDB version on the following servers:
- MySQL to MariaDB on CentOS 6/7 with cPanel
- MySQL to MariaDB on CentOS 7 with Plesk Onyx 17
- MySQL 5.1-5.5 to MariaDB 5.5 on CentOS 6
- MariaDB 5.5 to MariaDB 10.0 on CentOS 6
