Bugs Fixed

ProxySQL in its versions up to 1.x did not natively support Percona XtraDB Cluster (PXC). Instead, it relied on the flexibility offered by the scheduler. This approach allowed users to implement their own preferred way to manage the ProxySQL behaviour in relation to the Galera events.

From version 2.0 we can use native ProxySQL support for PXC.. The mechanism to activate native support is very similar to the one already in place for group replication.

In brief it is based on the table [runtime_]mysql_galera_hostgroups and the information needed is mostly the same:

• writer_hostgroup: the hostgroup ID that refers to the WRITER
• …

Recently I received several questions about rotating log files for ProxySQL, so I decided to draft it up as a blog post. Let me go by this using an example.

In my testing lab, I have set up a fairly default ProxySQL (version 1.4.13) service. The default location for the proxysql.log is in /var/lib/proxysql.

[root@proxysql ~]# ls -hal /var/lib/proxysql/proxysql.log*
-rw-------. 1 root root 4.9K Jan 30 18:47 /var/lib/proxysql/proxysql.log

I created a pretty basic default logrotate configuration to ensure my logfile rotates on a daily basis and five rotations are kept before expiring.

[root@proxysql ~]# cat /etc/logrotate.d/proxysql
/var/lib/proxysql/proxysql.log {
missingok
daily
notifempty
compress
create 0600 root root
rotate 5
}

First attempt

Let’s check whether this is actually the correct file that is used that we will be rotating. As it turned out it is!

[root@proxysql ~]# lsof | …

ProxySQL 1.4.14, 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.

Introduction –

                     At Mydbops we are exploring the latest MySQL technologies . Recently i was worked for one of our client the project. The requirement is setting up a three node InnoDB cluster with 3 node ProxySQL cluster .

We know that MySQL query cache is deprecated as of MySQL 5.7.20 and removed in MySQL 8.0 and It has been recommended to use ProxySQL (or other) external query cache instead.

In this blog post, we’ll present the ProxySQL query cache functionality and how does it help us.

How to setup ProxySQL between client and database servers is out of the scope of this article.
