Chapter 18. Reference
18.1. Data Grid Server 8.4.6 Readme
Information about Data Grid Server 14.0.21.Final-redhat-00001 distribution.
18.1.1. Requirements
Data Grid Server requires JDK 11 or later.
18.1.2. Starting servers
Use the server
script to run Data Grid Server instances.
Unix / Linux
$RHDG_HOME/bin/server.sh
Windows
$RHDG_HOME\bin\server.bat
Include the --help
or -h
option to view command arguments.
18.1.3. Stopping servers
Use the shutdown
command with the CLI to perform a graceful shutdown.
Alternatively, enter Ctrl-C from the terminal to interrupt the server process or kill it via the TERM signal.
18.1.4. Configuration
Server configuration extends Data Grid configuration with the following server-specific elements:
cache-container
- Defines cache containers for managing cache lifecycles.
endpoints
- Enables and configures endpoint connectors for client protocols.
security
- Configures endpoint security realms.
socket-bindings
- Maps endpoint connectors to interfaces and ports.
The default configuration file is $RHDG_HOME/server/conf/infinispan.xml
.
infinispan.xml
- Provides configuration to run Data Grid Server using default cache container with statistics and authorization enabled. Demonstrates how to set up authentication and authorization using security realms.
Data Grid provides other ready-to-use configuration files that are primarily for development and testing purposes.
$RHDG_HOME/server/conf/
provides the following configuration files:
infinispan-dev-mode.xml
-
Configures Data Grid Server specifically for cross-site replication with IP multicast discovery. The configuration provides
BASIC
authentication to connect to the Hot Rod and REST endpoints. The configuration is designed for development mode and should not be used in production environments. infinispan-local.xml
- Configures Data Grid Server without clustering capabilities.
infinispan-xsite.xml
- Configures cross-site replication on a single host and uses IP multicast for discovery.
log4j2.xml
- Configures Data Grid Server logging.
Use different configuration files with the -c
argument, as in the following example that starts a server without clustering capabilities:
Unix / Linux
$RHDG_HOME/bin/server.sh -c infinispan-local.xml
Windows
$RHDG_HOME\bin\server.bat -c infinispan-local.xml
18.1.5. Bind address
Data Grid Server binds to the loopback IP address localhost
on your network by default.
Use the -b
argument to set a different IP address, as in the following example that binds to all network interfaces:
Unix / Linux
$RHDG_HOME/bin/server.sh -b 0.0.0.0
Windows
$RHDG_HOME\bin\server.bat -b 0.0.0.0
18.1.6. Bind port
Data Grid Server listens on port 11222
by default.
Use the -p
argument to set an alternative port:
Unix / Linux
$RHDG_HOME/bin/server.sh -p 30000
Windows
$RHDG_HOME\bin\server.bat -p 30000
18.1.7. Clustering address
Data Grid Server configuration defines cluster transport so multiple instances on the same network discover each other and automatically form clusters.
Use the -k
argument to change the IP address for cluster traffic:
Unix / Linux
$RHDG_HOME/bin/server.sh -k 192.168.1.100
Windows
$RHDG_HOME\bin\server.bat -k 192.168.1.100
18.1.8. Cluster stacks
JGroups stacks configure the protocols for cluster transport. Data Grid Server uses the tcp
stack by default.
Use alternative cluster stacks with the -j
argument, as in the following example that uses UDP for cluster transport:
Unix / Linux
$RHDG_HOME/bin/server.sh -j udp
Windows
$RHDG_HOME\bin\server.bat -j udp
18.1.9. Authentication
Data Grid Server requires authentication.
Create a username and password with the CLI as follows:
Unix / Linux
$RHDG_HOME/bin/cli.sh user create username -p "qwer1234!"
Windows
$RHDG_HOME\bin\cli.bat user create username -p "qwer1234!"
18.1.10. Server home directory
Data Grid Server uses infinispan.server.home.path
to locate the contents of the server distribution on the host filesystem.
The server home directory, referred to as $RHDG_HOME
, contains the following folders:
├── bin ├── boot ├── docs ├── lib ├── server └── static
Folder | Description |
---|---|
| Contains scripts to start servers and CLI. |
|
Contains |
| Provides configuration examples, schemas, component licenses, and other resources. |
|
Contains |
| Provides a root folder for Data Grid Server instances. |
| Contains static resources for Data Grid Console. |
18.1.11. Server root directory
Data Grid Server uses infinispan.server.root.path
to locate configuration files and data for Data Grid Server instances.
You can create multiple server root folders in the same directory or in different directories and then specify the locations with the -s
or --server-root
argument, as in the following example:
Unix / Linux
$RHDG_HOME/bin/server.sh -s server2
Windows
$RHDG_HOME\bin\server.bat -s server2
Each server root directory contains the following folders:
├── server │ ├── conf │ ├── data │ ├── lib │ └── log
Folder | Description | System property override |
---|---|---|
| Contains server configuration files. |
|
| Contains data files organized by container name. |
|
|
Contains server extension files. |
|
| Contains server log files. |
|
18.1.12. Logging
Configure Data Grid Server logging with the log4j2.xml
file in the server/conf
folder.
Use the --logging-config=<path_to_logfile>
argument to use custom paths, as follows:
Unix / Linux
$RHDG_HOME/bin/server.sh --logging-config=/path/to/log4j2.xml
To ensure custom paths take effect, do not use the ~
shortcut.
Windows
$RHDG_HOME\bin\server.bat --logging-config=path\to\log4j2.xml
