Codership’s Galera Cluster Best Practices Webinar for MySQL DBAs and DevOps Part One is now available to watch here

This blog post discusses ProxySQL and MHA integration, and how they work together.

MHA (Master High Availability Manager and tools for MySQL) is almost fully integrated with the ProxySQL process. This means you can count on the MHA standard feature to manage failover, and ProxySQL to manage the traffic and shift from one server to another.

This is one of the main differences between MHA and VIP, and MHA and ProxySQL: with MHA/ProxySQL, there is no need to move IPs or re-define DNS.

The following is an example of an MHA configuration file for use with ProxySQL:

server default]
    user=mha
    password=mha
    ssh_user=root
    repl_password=replica
    manager_log=/tmp/mha.log
    manager_workdir=/tmp
    remote_workdir=/tmp
    master_binlog_dir=/opt/mysql_instances/mha1/logs …

This blog post discusses what is going on in the MySQL high availability market, and what Percona’s plans are for helping customers with high availability solutions.

One thing I like to tell people is that you shouldn’t view Percona as a “software” company, but as a “solution” company. Our goal has always been to provide the best solution that meets each customer’s situation, rather than push our own software, regardless of whether it is the best fit or not. As a result, we have customers running all kinds of MySQL “flavors”: MySQL, MariaDB, Percona Server, Amazon RDS and Google Cloud SQL. We’re happy to help customers be successful with the technology of their choice, and advise them on alternatives when we see a better fit.
