Orchestrator is a replication topology manager for MySQL. Features include: * The topology and status of the replication tree is automatically detected and monitored. * Either a GUI, CLI or API can be used to check the status and perform operations. * Supports automatic failover of the master, and the replication tree can be fixed when servers in the tree fail - either manually or automatically. * It is not dependent on any specific version or flavor of MySQL (MySQL, Percona Server, MariaDB or even MaxScale binlog servers). * Orchestrator supports many different types of topologies, from a single master -> slave to complex multi-layered replication trees consisting of hundreds of servers. * Orchestrator can make topology changes and will do so based on the state at that moment; it does not require a configuration to be defined with what corresponds to the database topology. * The GUI is not only there to report the status - one of the cooler things you can do is change replication just by doing a drag and drop in the web interface (of course you can do this and much more through the CLI and API as well).

#### Setup backend MySQL server
|
|
|
|
Setup a MySQL server for backend, and invoke the following:
|
|
|
|
CREATE DATABASE IF NOT EXISTS orchestrator;
|
|
CREATE USER 'orchestrator'@'127.0.0.1' IDENTIFIED BY 'orch_backend_password';
|
|
GRANT ALL PRIVILEGES ON `orchestrator`.* TO 'orchestrator'@'127.0.0.1';
|
|
|
|
Orchestrator uses a configuration file, located in:
|
|
%%ETCDIR%%/orchestrator.conf.json
|
|
|
|
Edit orchestrator.conf to match the above as follows:
|
|
|
|
...
|
|
"MySQLOrchestratorHost": "127.0.0.1",
|
|
"MySQLOrchestratorPort": 3306,
|
|
"MySQLOrchestratorDatabase": "orchestrator",
|
|
"MySQLOrchestratorUser": "orchestrator",
|
|
"MySQLOrchestratorPassword": "orch_backend_password",
|
|
...
|
|
|
|
#### Grant access to orchestrator on all your MySQL servers
|
|
|
|
CREATE USER 'orchestrator'@'orch_host' IDENTIFIED BY 'orch_topology_password';
|
|
GRANT SUPER, PROCESS, REPLICATION SLAVE, RELOAD ON *.* TO 'orchestrator'@'orch_host';
|
|
GRANT SELECT ON mysql.slave_master_info TO 'orchestrator'@'orch_host';
|
|
GRANT SELECT ON ndbinfo.processes TO 'orchestrator'@'orch_host'; -- Only for NDB Cluster
|
|
|
|
Replace `orch_host` with hostname or orchestrator machine (or do your
|
|
wildcards thing). Choose your password wisely. Modify the configuration file to
|
|
match:
|
|
|
|
"MySQLTopologyUser": "orchestrator",
|
|
"MySQLTopologyPassword": "orch_topology_password",
|
|
|
|
By default, orchestrator listens on 127.0.0.1:3000 and is configured to be
|
|
read-only. Please update the configuration file if you would like to change
|
|
this.
