    # There is insufficient memory for the Java Runtime Environment to continue.
    # Native memory allocation (mmap) failed to map 2060255232 bytes for committing reserved memory.
    # Possible reasons:
    #   The system is out of physical RAM or swap space
    #   The process is running with CompressedOops enabled, and the Java Heap may be blocking the growth of the native heap
    # Possible solutions:
    #   Reduce memory load on the system
    #   Increase physical memory or swap space
    #   Check if swap backing store is full
    #   Decrease Java heap size (-Xmx/-Xms)
    #   Decrease number of Java threads
    #   Decrease Java thread stack sizes (-Xss)
    #   Set larger code cache with -XX:ReservedCodeCacheSize=

上述是错误日志，就是我服务器的配置内存不够，es默认配置2g内存，所以报错了。那么我们要修改一下内存配置，适合我们服务器。

打开es的安装目录 /config/jvm.options   将其内存设置修改为对应复合的，我这里就修改为256了
