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 1.4.6 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 1.4.6 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-32: Now,
proxysql_adminscript can configure multiple clusters in ProxySQL, when there are unique cluster names specified by the
wsrep_cluster_nameoption, and the
proxysql_admin.cnfconfiguration contains different ProxySQL READ/WRITE hostgroup and different application user for each cluster. Currently multiple clusters support is not compatible with host priority feature, which works only with a single cluster.
- PR #81: The new version substantially increases the number of test cases in the ProxySQL Admin test-suite.
- Fixed #PSQLADM-35:
proxysql_galera_checkermonitoring script was unable to discover new writer nodes.
- Fixed #PSQLADM-36: upgrade to ProxySQL 1.4.5 from the previous version was broken.
- Fixed #79 by properly quoting the
MONITOR_USERNAMEenvironment variable in the admin script query.
