Chapter 18. Reference 18.1. Data Grid Server 8.5.2 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 Windows Tip 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 USDRHDG_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. USDRHDG_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. infinispan-memcached.xml Configures Data Grid Server to behave like a default Memcached server, listening on port 11221 and without authentication. infinispan-resp.xml Configures Data Grid Server to behave like a default Redis server, listening on port 6379 and without authentication. 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 Windows 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 Windows 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 Windows 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 Windows 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 Windows 18.1.9. Authentication Data Grid Server requires authentication. Create a username and password with the CLI as follows: Unix / Linux Windows 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 USDRHDG_HOME , contains the following folders: Folder Description /bin Contains scripts to start servers and CLI. /boot Contains JAR files to boot servers. /docs Provides configuration examples, schemas, component licenses, and other resources. /lib Contains JAR files that servers require internally. Do not place custom JAR files in this folder. /server Provides a root folder for Data Grid Server instances. /static 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 Windows Each server root directory contains the following folders: Folder Description System property override /server/conf Contains server configuration files. infinispan.server.config.path /server/data Contains data files organized by container name. infinispan.server.data.path /server/lib Contains server extension files. This directory is scanned recursively and used as a classpath. infinispan.server.lib.path Separate multiple paths with the following delimiters: : on Unix / Linux ; on Windows /server/log Contains server log files. infinispan.server.log.path 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 Tip To ensure custom paths take effect, do not use the ~ shortcut. Windows
