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 1.4.7 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 1.4.7 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:
proxysql-statustool to dump ProxySQL configuration and statistics.
- PSQLADM-2: ProxySQL galera checker script didn’t check if another instance of itself is already running. While running more then one copy of
proxysql_galera_checkerin the same runtime environment at the same time is still not supported, the introduced fix is able to prevent duplicate script execution in most cases.
- PSQLADM-40: ProxySQL scheduler generated a lot of
proxysql_node_monitorprocesses in case of wrong ProxySQL credentials in
- PSQLADM-41: Timeout error handling was improved with clear messages.
- PSQLADM-42: An inconsistency of the date format in ProxySQL and scripts was fixed.
proxysql_galera_checkerdidn’t take into account the possibility of special characters presence in
proxysql_galera_checkergenerated unclear errors in the
proxysql.logfile if wrong credentials where passed.
proxysql_node_monitorscript incorrectly split the hostname and the port number in URLs containing hyphen character.
