ProxySQL 1.4.12 and proxysql-admin (2018-11-13)

ProxySQL release, 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 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 1.4.12 source and binary packages are available from the Percona download page for ProxySQL include ProxySQL Admin – a tool developed by Percona to configure Percona XtraDB Cluster nodes into ProxySQL. Docker images are available as well. You can download the original ProxySQL from GitHub. ProxySQL offers the ProxySQL documentation.

Improvements

  • PSQLADM-68: Scripts are now compatible with Percona XtraDB Cluster (PXC) hosts using IPv6

  • PSQLADM-107: In include-slaves, a slave would always be moved into the write hostgroup even if the whole cluster went down. A new option –use-slave-as-writer specifies whether or not the slave is added to the write hostgroup.

Bugs Fixed

  • PSQLADM-110: In some cases, pattern cluster hostname did not work with proxysql-admin.

  • PSQLADM-104: proxysql-admin testsuite bug fixes.

  • PSQLADM-113: proxysql_galera_checker assumed that parameters were given in the long format.

  • PSQLADM-114: In some cases, ProxySQL could not be started

  • PSQLADM-115: proxysql_node_monitor could fail with more than one command in the ProxySQL scheduler.

  • PSQLADM-116: In some cases, the ProxySQL scheduler was reloading servers on every run

  • PSQLADM-117: The –syncusers option did not work when enabling cluster

  • PSQLADM-125: The check-is-galera-checker-running function was not preventing multiple instances of the script from running.

Other bugs fixed: PSQLADM-112, PSQLADM-120
