MaxCtrl

MaxCtrl is a command line administrative client for MaxScale which uses the MaxScale REST API for communication. It has replaced the legacy MaxAdmin command line client that is no longer supported or included.

By default, the MaxScale REST API listens on port 8989 on the local host. The default credentials for the REST API are admin:mariadb. The users used by the REST API are the same that are used by the MaxAdmin network interface. This means that any users created for the MaxAdmin network interface should work with the MaxScale REST API and MaxCtrl.

For more information about the MaxScale REST API, refer to the REST API documentation and the Configuration Guide.

Set options:
  --force  If combined with the `maintenance` state, this forcefully closes all connections to the target server  [boolean] [default: false]

Options:
  --version  Show version number  [boolean]
  --help     Show help  [boolean]

If <server> is monitored by a monitor, this command should only be used to set the server into the `maintenance` or the `drain` state. Any other states will be overridden by the monitor on the next monitoring interval. To manually control server states, use the `stop monitor <name>` command to stop the monitor before setting the server states manually.

When a server is set into the `drain` state, no new connections to it are allowed but existing connections are allowed to gracefully close. Servers with the `Master` status cannot be drained or set into maintenance mode. To clear a state set by this command, use the `clear server` command.

To forcefully close all connections to a server, use `set server <name> maintenance --force`

This command drains the server of connections by first removing it from all services after which it waits until all connections are closed. When all connections are closed, the server is put into the `maintenance` state and added back to all the services where it was removed from. To take the server back into use, execute `clear server <server> maintenance`.

Warning: This command is not safe to interrupt. If interrupted, the servers might not be added back to the service. For a better alternative, use `set server <server> drain`.

This command links targets to a service, making them available for any connections that use the service. A target can be a server, another service or a cluster (i.e. a monitor). Before a server is linked to a service, it should be linked to a monitor so that the server state is up to date. Newly linked targets are only available to new connections, existing connections will use the old list of targets. If a monitor (a cluster of servers) is linked to a service, the service must not have any other targets linked to it.

To display the service parameters, execute `show service <service>`. Some routers support runtime configuration changes to all parameters. Currently all readconnroute, readwritesplit and schemarouter parameters can be changed at runtime. In addition to module specific parameters, the following list of common service parameters can be altered at runtime:

[
    "user",
    "passwd",
    "enable_root_user",
    "max_connections",
    "connection_timeout",
    "auth_all_servers",

    "max_slave_connections",
    "max_slave_replication_lag",
    "retain_last_statements"
]

  -t, --timeout   Request timeout in plain milliseconds, e.g '-t 1000', or as duration with suffix [h|m|s|ms], e.g. '-t 10s'  [string] [default: "10000"]

The order of the filters given as the second parameter will also be the order in which queries pass through the filter chain. If no filters are given, all existing filters are removed from the service.

For example, the command `maxctrl alter service filters my-service A B C` will set the filter chain for the service `my-service` so that A gets the query first after which it is passed to B and finally to C. This behavior is the same as if the `filters=A|B|C` parameter was defined for the service.

This command will alter all MaxScale instances given in the --hosts option to represent the <target> MaxScale. Value of <target> must be in HOST:PORT format. Synchronization can be attempted again if a previous attempt failed due to a network failure or some other ephemeral error. Any other errors require manual synchronization of the MaxScale configuration files and a restart of the failed Maxscale.

Note: New objects created by `cluster sync` will have a placeholder value and must be manually updated. Passwords for existing objects will not be updated by `cluster sync` and must also be manually updated.
