**Installation**: [https://www.percona.com/doc/percona-xtradb-cluster/LATEST/howtos/proxysql-v2.html#installing-proxysql-v2](https://www.percona.com/doc/percona-xtradb-cluster/LATEST/howtos/proxysql-v2.html#installing-proxysql-v2)


*ProxySQL* 2.1.1, released by [ProxySQL](https://www.proxysql.com/), is now available for download in the [Percona repository](https://www.percona.com/software/percona-software-repositories-for-mysql) along with an updated version of **Percona**’s proxysql-admin tool.

*ProxySQL* is a high-performance proxy, currently for MySQL, and database servers in the MySQL ecosystem (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.

The *ProxySQL* 2.1.1 source and binary packages available from the [Percona download page for ProxySQL 2](https://www.percona.com/downloads/proxysql2/) include ProxySQL Admin – a tool developed by **Percona** to configure **Percona XtraDB Cluster** nodes into *ProxySQL*. Docker images for 2.1.1 are available as well.

You can [download the original ProxySQL from GitHub](https://github.com/sysown/proxysql/releases). *ProxySQL* offers the [ProxySQL documentation](https://proxysql.com/documentation/). For more information on the issues fixed, features, or enhancements, see the *ProxySQL* [2.1.0 release notes](https://github.com/sysown/proxysql/releases/tag/v2.1.0) and [2.1.1 release notes](https://github.com/sysown/proxysql/releases/tag/v2.1.1)

**NOTE**: An upgrade from ProxySQL v1.x to ProxySQL v2.x requires the user to manually remove the ProxySQL v1.x packages. After that operation, the user can install ProxySQL v2.x.

*ProxySQL* is available under Open Source license GPLv3.
