怎么在Linux下改变JMeter内存

1.找到相应的bin目录下面的jmeter文件
2.启动出现：
Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000c0000000, 1073741824, 0) failed; error='Cannot allocate memory' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 1073741824 bytes for committing reserved memory.
# An error report file with more information is saved as:
# /usr/local/jmeter/apache-jmeter-4.0/bin/hs_err_pid5855.log

解决：
    编辑jmeter
    搜索 : "${HEAP:="-Xms1g -Xmx1g -XX:MaxMetaspaceSize=256m"}"
    改变初始堆内存和最大堆内存

3.发布变正常启动。
