我正尝试按照以下指南在我的本地 Ubuntu 机器上安装 elasticsearch:
https://www.elastic.co/guide/en/elasticsearch/reference/current/_installation.html
,当尝试运行“./elasticsearch”时,出现以下错误:
Java HotSpot(TM) 64-Bit Server VM warning: INFO: <br>
os::commit_memory(0x00007f0e50cc0000, 64075595776, 0) failed; <br>
error='Cannot allocate memory' (errno=12) <br>
There is insufficient memory for the Java Runtime Environment to continue.<br>
Native memory allocation (mmap) failed to map 64075595776 bytes for committing reserved memory
这是内存统计信息:
total used free shared buffers cached
Mem: 8113208 4104900 4008308 44244 318076 1926964
-/+ buffers/cache: 1859860 6253348
Swap: 7812092 0 7812092
日志中的错误信息:
There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 64075595776 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=

已经尝试过早期版本,使用 apt 从存储库安装,没有任何效果。
有人知道可能是什么问题吗?
最佳答案
看起来您正在尝试使用默认选项启动 ElasticSearch,这会尝试将堆栈大小设置为 2Go。如果你没有那个免费的……kaboom(默默地)。
查看 /etc/elasticsearch/jvm.options
并修改以下行:
-Xms2g
-Xmx2g
适合您可用内存的内容。但请注意,ElasticSearch 是一个非常大的内存消耗者并且想要它的一切。在 2Go 限制下,您可能无法获得有用的系统。
