在Linux服务器上使用JMeter进行压力测试时遇到报错
java.lang.OutOfMemoryError: Java heap space Dumping heap to java_pid21100.hprof ... Heap dump file created [1165614889 bytes in 55.695 secs]

To run JMeter, run the jmeter.bat (for Windows) or jmeter (for Unix) file
for windows:
jmeter.bat - run JMeter (in GUI mode by default)
jmeter-n.cmd - drop a JMX file on this to run a non-GUI test jmeter-n-r.cmd - drop a JMX file on this to run a non-GUI test remotely jmeter-t.cmd - drop a JMX file on this to load it in GUI mode jmeter-server.bat - start JMeter in server mode mirror-server.cmd - runs the JMeter Mirror Server in non-GUI mode shutdown.cmd - Run the Shutdown client to stop a non-GUI instance gracefully stoptest.cmd - Run the Shutdown client to stop a non-GUI instance abruptly
for linux:
jmeter - run JMeter (in GUI mode by default). Defines some JVM settings which may not work for all JVMs.
jmeter-server - start JMeter in server mode (calls jmeter script with appropriate parameters) jmeter.sh - very basic JMeter script with no JVM options specified. mirror-server.sh - runs the JMeter Mirror Server in non-GUI mode shutdown.sh - Run the Shutdown client to stop a non-GUI instance gracefully stoptest.sh - Run the Shutdown client to stop a non-GUI instance abruptly
修改：
windows编辑jmeter.bat,修改set HEAP的值
set JVM_ARGS="-Xms1024m -Xmx1024m " 解释一下各个参数： -Xms1024M：初始化堆内存大小（注意，不加M的话单位是KB） -Xmx1024M：最大堆内存大小
linux可以这样写：JVM_ARGS="-Xms1024m -Xmx1024m" (JVM_ARGS代表启动JMeter时要使用的Java选项。这些将最后添加到java命令)，以下是举例
JVM_ARGS="-Xms4g -Xmx4g -XX:MaxMetaspaceSize=1g"
-XX:MaxPermSize=256M：最大类加载内存池大小
重启jmeter生效
