description	Used to start or stop the project's server in development mode via scripts, or run DtAdmin for test cluster O&M operations, or run benchmarks.

Build and Basic Instructions

After executing mvn clean package -DskipUTs, the target directory under the project root will contain the dongting-dist directory, which includes:

• bin: Various startup and shutdown scripts, each providing bat/ps1/sh formats; examples below use sh format
• lib: Dependency JAR directory
• conf: Configuration file directory
• logs: Log file directory
• data: Data directory, generated at runtime

bin

• start-dongting.sh: Starts the dongting (DtKV) server; after execution, the Java process runs in the background. Entry point is the Bootstrap class.
• stop-dongting.sh: Stops the dongting (DtKV) server; after execution, the process exits
• benchmark.sh: Runs the benchmark; after execution, the process exits. Running without parameters prints usage. Entry point is the DtBenchmark class.
• dongting-admin.sh: Runs the O&M tool; after execution, the process exits. Running without parameters prints usage. Entry point is the DtAdmin class.

After build completes, if start-dongting.sh is run without any modifications, it will start a single-node cluster by default, listening on port 9331 (replicatePort) and 9332 (servicePort), with nodeId 1, containing a DtKV server with groupId 0.

All scripts except stop-dongting start a Java process. The JDK can be specified by setting JAVA_HOME environment variable.

conf

• config.properties: Configuration file for dongting (DtKV) server, specifying nodeId, replicatePort, servicePort, dataDir, etc.
• client.properties: Configuration file for benchmark, specifying servers list; benchmark needs to connect to servicePort
• servers.properties: Configuration file for dongting (DtKV) server, also read by dongting-admin, specifying servers list (replicatePort), and defining groups and their configurations
• logback-server.xml: Log configuration for dongting (DtKV) server
• logback-admin.xml: Log configuration for dongting-admin
• logback-benchmark.xml: Log configuration for benchmark

log

• dongting-server.log: Logback log for Java process started by dongting-server.sh
• start.log: Console log for Java process started by start-dongting.sh
• dongting-admin.log: Logback log for Java process started by dongting-admin.sh
• dongting-benchmark.log: Logback log for Java process started by benchmark.sh
