kafka 启动 报错cannot allocate memory，即内存不足

错误提示：
Java Hotspot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000c5330000, 986513408, 0) failed; error=‘Cannot allocate memory‘ (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 986513408 bytes for committing reserved memory.
# An error report file with more information is saved as:
# hs_err_pid5535.log
解决办法：
将 kafka-server-start.sh的
export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G"
修改为
export KAFKA_HEAP_OPTS="-Xmx256M -Xms128M"
因为我的内存是1G
