環(huán)境是linux
1、http://rocketmq.apache.org/docs/quick-start/?按照官網(wǎng)來啟動mqnamesrv和mqbroker報(bào)錯(cuò)?
錯(cuò)誤如下?
There is insufficient memory for the Java Runtime Environment to continue.

There is insufficient memory for the Java Runtime Environment to continue.??
Native memory allocation (mmap) failed to map 8589934592 bytes for committing reserved memory.??
Possible reasons:??
The system is out of physical RAM or swap space??
In 32 bit mode, the process size limit was hit??
Possible solutions:??
Reduce memory load on the system??
Increase physical memory or swap space??
Check if swap backing store is full??
Use 64 bit Java on a 64 bit OS??
Decrease Java heap size (-Xmx/-Xms)??
Decrease number of Java threads??
Decrease Java thread stack sizes (-Xss)??
Set larger code cache with -XX:ReservedCodeCacheSize=??
This output file may be truncated or incomplete.

Out of Memory Error (os_linux.cpp:2640), pid=2428, tid=0x00007fada5259700

JRE version: (8.0_172-b11) (build )??
Java VM: Java HotSpot(TM) 64-Bit Server VM (25.172-b11 mixed mode linux-amd64 compressed oops)?
Java運(yùn)行時(shí)環(huán)境的內(nèi)存不足，無法繼續(xù)，本機(jī)內(nèi)存分配（mmap）未能映射8589934592字節(jié)，用于提交保留內(nèi)存?
解決辦法，找到runserver.sh和runbroker.sh，編輯?

#JAVA_OPT="${JAVA_OPT} -server -Xms8g -Xmx8g -Xmn4g" (默認(rèn)需要內(nèi)存空間)

JAVA_OPT=”${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn125m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m”?
改成如上就可以了
