Rhino ships with a pair of scripts for managing nodes and SLEE state. Rhino.sh controls the startup and shutdown of nodes on a host. Slee.sh controls the state of the SLEE in a cluster.
The scripts contain logic to detect the nodes running on a host, but it is recommended to set the RHINO_SLEE_NODES and RHINO_QUORUM_NODES variables explicitly
(this is typically done in $RHINO_BASE/rhino.env).
rhino.sh
The rhino.sh script is used to start and stop Rhino nodes on a host.
It can be used to manage individual nodes or all the nodes on the local host.
If starting a cluster for the first time (i.e. where no previous cluster state exists) and the 'make primary' option to create-node.sh
was not specified for one of the nodes, then the cluster must be manually made primary (by using the make-primary.sh script in a node directory).
|
Do not add the '-p' start argument to the rhino.sh script, it will result in nodes failing to start correctly. |
Usage
The rhino.sh script takes a command and an optional list of nodes to act on.
rhino.sh start|stop|kill|status|restart [-nodes node1,node2,…]
The command may be:
| Argument | Description |
|---|---|
|
Start Rhino nodes into operational state |
|
Shutdown Rhino nodes, first stopping the SLEE if needed |
|
Forcibly terminate Rhino nodes |
|
get the status of the nodes installed on this host system |
|
Forcibly restart Rhino nodes regardless of SLEE state |
Starting all local nodes
$ ./rhino.sh start Rhino node 101 startup initiated with 0s delay Rhino node 102 startup initiated with 30s delay Rhino node 105 startup initiated with 60s delay
Starting a subset of the local nodes
$ ./rhino.sh start -nodes 101,105 Rhino node 101 startup initiated with 0s delay Rhino node 105 startup initiated with 30s delay
Shutting down all local nodes
$ ./rhino.sh stop Stopping Rhino nodes 101,102,105 Executing "rhino-console stop -ifneeded -nodes 101,102" Stopping SLEE on node(s) [101,102] SLEE transitioned to the Stopping state on node 101 SLEE transitioned to the Stopping state on node 102 Waiting for SLEE to enter the Stopped state on node(s) 101,102 Executing "rhino-console waitonstate stopped -nodes 101,102" SLEE is in the Stopped state on node(s) [101,102] Nodes to shut down: 105 101 102 Executing "rhino-console shutdown -nodes 105" Shutting down node(s) [101] (using Rhino's default shutdown timeout) Shutdown successful Executing "rhino-console shutdown -nodes 101" Shutting down node(s) [101] (using Rhino's default shutdown timeout) Shutdown successful Executing "rhino-console shutdown -nodes 102" Shutting down node(s) [101] (using Rhino's default shutdown timeout) Shutdown successful
Shutting down a single node
$ ./rhino.sh stop -nodes 101 Stopping Rhino nodes 101,102,105 Executing "rhino-console stop -ifneeded -nodes 101" Stopping SLEE on node(s) [101] SLEE transitioned to the Stopping state on node 101 Waiting for SLEE to enter the Stopped state on node(s) 101 Executing "rhino-console waitonstate stopped -nodes 101" SLEE is in the Stopped state on node(s) [101] Nodes to shut down: 101 Executing "rhino-console shutdown -nodes 101" Shutting down node(s) [101] (using Rhino's default shutdown timeout) Shutdown successful
Forcibly stopping a node
$ ./rhino.sh kill -nodes 201 Killing node 201 process id 5770 Killing node 201 startup script process id 4763
slee.sh
The slee.sh script is used to control SLEE state for a cluster.
It can be used to manage individual nodes or the whole cluster.
Usage
The slee.sh script takes a command and an optional list of nodes to act on.
slee.sh start|stop|reboot|shutdown|state [-ifneeded] {-local | -cluster | -nodes node1,node2,…} -states {running|r|stopped|s},…
The command may be:
| Command | Description |
|---|---|
|
Start the SLEE |
|
Stop the SLEE |
|
Shutdown and restart nodes cleanly |
|
Shutdown nodes |
|
Get the SLEE state |
The start, stop, reboot and shutdown commands take an argument specifying which nodes to act on.
That argument can be
| Argument | Description |
|---|---|
-local |
Only change the state of the nodes on this host |
-cluster |
Change the state on the entire cluster |
-nodes node1,node2… |
Change the state of the listed nodes |
The reboot command also takes an argument specifing the states the nodes should be rebooted to.
That argument can be a single value to apply to all nodes or a list of one state per node.
The states are: running (r) and stopped (s)
| Argument | Description |
|---|---|
-states |
The state to restart the nodes to.
Can be one of |
