[Bug] PD, Store process log files do not scroll

The log file defined by the OUTPUT variable in the start-hugegraph-pd.sh script does not scroll according to the rules defined by log4j2.xml because the OUTPUT variable is not referenced or used within the log4j2.xml configuration file. The log4j2 configuration specifies log file paths using the ${LOG_PATH} and ${FILE_NAME} properties, but there is no mention of an OUTPUT variable.

To ensure the log file scrolls according to the rules defined in log4j2.xml, you need to make sure that the OUTPUT variable in your script matches the log file paths specified in the log4j2.xml configuration.

For example, if OUTPUT is intended to be the main log file, it should match ${LOG_PATH}/${FILE_NAME}.log:

OUTPUT="logs/hugegraph-pd.log"

Ensure that the script and the log4j2 configuration are aligned in terms of log file paths. The log4j2.xml configuration uses the following properties for log file paths:

<properties>
    <property name="LOG_PATH">logs</property>
    <property name="FILE_NAME">hugegraph-pd</property>
</properties>

The main log file is defined as:

<RollingRandomAccessFile name="file" fileName="${LOG_PATH}/${FILE_NAME}.log"
                         filePattern="${LOG_PATH}/$${date:yyyy-MM}/${FILE_NAME}-%d{yyyy-MM-dd}-%i.log"
                         bufferedIO="true" bufferSize="524288" immediateFlush="false">
    <ThresholdFilter level="TRACE" onMatch="ACCEPT" onMismatch="DENY" />
    <PatternLayout pattern="%-d{yyyy-MM-dd HH:mm:ss} [%t] [%p] %c{1.} - %m%n" />
    <Policies>
        <SizeBasedTriggeringPolicy size="128MB" />
        <TimeBasedTriggeringPolicy interval="1" modulate="true" />
    </Policies>
    <DefaultRolloverStrategy max="16">
        <Delete basePath="${LOG_PATH}" maxDepth="2">
            <IfFileName glob="*/*.log" />
            <IfAny>
                <IfAccumulatedFileSize exceeds="2GB" />
                <IfAccumulatedFileCount exceeds="100" />
            </IfAny>
        </Delete>
    </DefaultRolloverStrategy>
</RollingRandomAccessFile>

Make sure the OUTPUT variable in your script is set to logs/hugegraph-pd.log to match the log file path defined in log4j2.xml ^[1]^[2].
