ProxySQL 1.4.13 and Updated proxysql-admin Tool

ProxySQL 1.4.13, released by ProxySQL, is now available for download in the Percona Repository along with an updated version of Percona’s proxysql-admin tool.

ProxySQL is a high-performance proxy, currently for MySQL and its forks (like Percona Server for MySQL and MariaDB). It acts as an intermediary for client requests seeking resources from the database. René Cannaò created ProxySQL for DBAs as a means of solving complex replication topology issues.

ProxySQL Series : Query Cache with ProxySQL

We know that MySQL query cache is deprecated as of MySQL 5.7.20 and removed in MySQL 8.0 and It has been recommended to use ProxySQL (or other) external query cache instead.

In this blog post, we’ll present the ProxySQL query cache functionality and how does it help us.

How to setup ProxySQL between client and database servers is out of the scope of this article.

MySQL Setup at Hostinger Explained

Ever wondered how hosting companies manage their MySQL database architecture? At Hostinger, we have various MySQL setups starting from the standalone replica-less instances to Percona XtraDB Cluster (later just PXC), ProxySQL routing-based and even absolutely custom and unique solutions which I’m going to describe in this blog post.

We do not have elephant-sized databases for internal services like API, billing, and clients. Thus almost every decision ends up with high availability as a top priority instead of scalability.

Still, scaling vertically is good enough for our case, as the database size does not exceed 500GB. One and the top requirements is the ability to access the master …

How to Fix ProxySQL Configuration When it Won’t Start

With the exception of the three configuration variables described here, ProxySQL will only parse the configuration files the first time it is started, or if the proxysql.db file is missing for some other reason.

If we want to change any of this data we need to do so via ProxySQL’s admin interface and then save them to disk. That’s fine if ProxySQL is running, but what if it won’t start because of these values?

For example, perhaps we accidentally configured ProxySQL to run on port 3306 and restarted it, but there’s already a production MySQL instance running on this port. ProxySQL won’t start, so we can’t edit the value that way:

2018-10-02 09:18:33 network.cpp:53:listen_on_port(): [ERROR] bind(): Address already in use

We could delete proxysql.db and have it reload the configuration files, but …
