In this post I’ll give to you the steps to compile Percona Server for MySQL 5.7.22 in Raspberry Pi 3. Why? Well because in general this little computer is cheap, has low power consumption, and is great to use as a test machine for developers.

By default Raspbian OS includes very few versions of MySQL to install

$ apt-cache search mysql | grep server
...
mariadb-server-10.0 - MariaDB database server binaries
mariadb-server-10.1 - MariaDB database server binaries
mariadb-server-core-10.0 - MariaDB database core server files
mariadb-server-core-10.1 - MariaDB database core server files
mysql-server - MySQL database server binaries and system database setup [transitional] (5.5)
...

If you want to install MySQL or MariaDB on an ARM architecture using official pre-built binaries, you are limited to those distributions and versions.

In this webinar, I will discuss the external tools, toolkits and graphical instruments most valued by Support teams and customers. I will show the main advantages of these tools, and provide examples on how to effectively …

In this blog post, we’ll look at what is needed when migrating MySQL users to Amazon RDS. We’ll discuss how we can transform MySQL user grants and make them compatible with Amazon RDS.

In order to deliver a managed service experience, Amazon RDS does not provide shell access to the underlying operating system. It also restricts access to certain procedures that require advanced privileges.

Every MySQL instance has some users with ALL PRIVILEGES, and you can’t directly migrate these users to Amazon RDS because it does not support following privileges for regular users.

• SUPER – Enable use of other administrative operations such as CHANGE MASTER TO, KILL, PURGE BINARY …
