kafka启动过程报错，配置没有问题，这就懵了！！

Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000c0130000, 986513408, 0) failed; error='Cannot allocate memory' (errno=12)

说是内存不足，没办法，请教同学之后了解到kafka默认内存是1g，然后直接vim为100m就好了，具体就是：

{$KAFKA_HOME}/bin下，直接

vim kafka-server-start.sh

然后更改其中的export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G"
为export KAFKA_HEAP_OPTS="-Xmx100m -Xms100m"
