ProxySQL 1.4.5ProxySQL 1.4.8, 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.

The ProxySQL 1.4.8 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 1.4.8 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:

Usability improvement:

  • PR #84: Now proxysql-status tool dumps host_priority and proxysql-admin.cnf. Also output format was changed.

Other improvements and bug fixes:

  • PR #66: --syncusers option now makes ProxySQL-admin to update the user’s password in ProxySQL database if there is any password difference between ProxySQL user and MySQL user.
  • PSQLADM-45: it was unclear from the help screen, that --config-file option requires an argument.
  • PSQLADM-48:  ${PROXYSQL_DATADIR}/${CLUSTER_NAME}_mode file was not created at ProxySQL-admin upgrade (1.4.5 or before to 1.4.6 onwards).
  • PSQLADM-52: The  proxysql_galera_checker script was not checking empty query rules.
  • PSQLADM-54: proxysql_node_monitor did not change OFFLINE_HARD status properly for the coming back online nodes.
