The tutorials combine the Galera and MariaDB monitor configuration as well as the server configuration sections that were duplicated for all tutorials. This should make the documentation easier to maintain.

# Configuring the MariaDB Monitor
|
|
|
|
This document describes how to configure a MariaDB master-slave cluster monitor to be used with MaxScale.
|
|
|
|
## Configuring the Servers
|
|
|
|
The first step is to define the servers that make up the cluster. These servers will be used by the services and are monitored by the monitor.
|
|
|
|
```
|
|
[dbserv1]
|
|
type=server
|
|
address=192.168.2.1
|
|
port=3306
|
|
protocol=MariaDBBackend
|
|
|
|
[dbserv2]
|
|
type=server
|
|
address=192.168.2.2
|
|
port=3306
|
|
protocol=MariaDBBackend
|
|
|
|
[dbserv3]
|
|
type=server
|
|
address=192.168.2.3
|
|
port=3306
|
|
protocol=MariaDBBackend
|
|
```
|
|
|
|
## Configuring the Monitor
|
|
|
|
The next step is to define the monitor that monitors the servers.
|
|
|
|
```
|
|
[Replication-Monitor]
|
|
type=monitor
|
|
module=mariadbmon
|
|
servers=dbserv1, dbserv2, dbserv3
|
|
user=monitor_user
|
|
password=my_password
|
|
monitor_interval=2000
|
|
```
|
|
|
|
The mandatory parameters are the object type, the monitor module to use, the
|
|
list of servers to monitor and the username and password to use when connecting
|
|
to the servers. The `monitor_interval` parameter controls how many milliseconds
|
|
the monitor waits between each monitoring loop.
|
|
|
|
## Monitor User
|
|
|
|
The monitor user requires the REPLICATION CLIENT privileges to do basic
|
|
monitoring. To create a user with the proper grants, execute the following SQL.
|
|
|
|
```
|
|
CREATE USER 'monitor_user'@'%' IDENTIFIED BY 'my_password';
|
|
GRANT REPLICATION CLIENT on *.* to 'monitor_user'@'%';
|
|
```
