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.
The ProxySQL 1.4.5 source and binary packages available at https://percona.com/downloads/proxysql include ProxySQL Admin – a tool, developed by Percona to configure Percona XtraDB Cluster nodes into ProxySQL. Docker images for release 1.4.5 are available as well: https://hub.docker.com/r/percona/proxysql/. You can download the original ProxySQL from https://github.com/sysown/proxysql/releases.
This release fixes the following bugs in ProxySQL Admin:
- #PSQLADM-6: If the cluster node goes offline, the
proxysql_node_monitorscript now sets the node status as
OFFLINE_HARD, and does not remove it from the ProxySQL database. Also, logging is consistent regardless of the cluster node online status.
- #PSQLADM-30: Validation was added for the host priority file.
- #PSQLADM-33: Added
--proxysql-datadiroption to run the
proxysql-adminscript with a custom ProxySQL data directory.
- Also, BATS test suite was added for the
- Fixed#PSQLADM-5: PXC mode specified with
proxysql-adminwith use of
--modeparameter was not persistent.
- Fixed#PSQLADM-8: ProxySQL High CPU load took place when
ProxySQL is available under OpenSource license GPLv3.
