篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Elasticsearch7.x 配置解析jvm参数相关的知识，希望对你有一定的参考价值。
参考技术A 源码地址 https://github.com/elastic/elasticsearchES配置文件在$ES_HOME/config目录下,包含三个配置文件
jvm.options 关于JVM配置相关的
## JVM configuration
################################################################
## IMPORTANT: JVM heap size 重要的配置 堆内存
################################################################
##
## You should always set the min and max JVM heap
## size to the same value. For example, to set
## the heap to 4 GB, set:
## 初始堆和最大堆 设置相等 原因 : JVM初始分配的内存由-Xms指定，默认是物理内存的1/64；JVM最大分配的内存由-Xmx指定，默认是物理内存的1/4。默认空余堆内存小于40%时，JVM就会增大堆直到-Xmx的最大限制；空余堆内存大于70%时，JVM会减少堆直到-Xms的最小限制。因此服务器一般设置-Xms、-Xmx相等以避免在每次GC后调整堆的大小。
## -Xms4g
## -Xmx4g
## 关于堆的大小，参考官方文章，64位机器上大内存的使用最佳建议。
## See https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html
## for more information
##
################################################################
# Xms represents the initial size of total heap space
# Xmx represents the maximum size of total heap space
-Xms$heap.min
-Xmx$heap.max
################################################################
## Expert settings 顾名思义，没事不要乱动
################################################################
##
## All settings below this section are considered
## expert settings. Don't tamper with them unless
## you understand what you are doing

################################################################
## GC configuration CMS收集器 重点说下这两个参数，一般是成对出现，
XX:CMSInitiatingOccupancyFraction 指设定CMS在对内存占用率达到75%的时候开始GC
-XX+UseCMSInitiatingOccupancyOnly JVM通过CMSInitiatingOccupancyFraction设置的阀值来启动gc动作，划重点 1每一次 2 意味着gc动作不是通过运行时收集的数据来启动。
-XX:+UseConcMarkSweepGC
-XX:CMSInitiatingOccupancyFraction=75
-XX:+UseCMSInitiatingOccupancyOnly
## G1GC Configuration
# NOTE: G1GC is only supported on JDK version 10 or later. g1就不多说了，生产环境10+的应该很少。
# To use G1GC uncomment the lines below.
# 10-:-XX:-UseConcMarkSweepGC
# 10-:-XX:-UseCMSInitiatingOccupancyOnly
# 10-:-XX:+UseG1GC
# 10-:-XX:G1ReservePercent=25
# 10-:-XX:InitiatingHeapOccupancyPercent=30
那么，到底是选择CMS还是G1还是ZGC 其实取决你最终的节点内存配置，按照官方建议不超过64G的话，小于32G CMS 大于32小于64 G1。
## DNS cache policy
稍微解释一下，ES本身用自己的DNS缓存策略覆盖了JDK默认策略，还是贴个源码来看
启动类 org.elasticsearch.bootstrap.Elasticsearch.java
private static void overrideDnsCachePolicyProperties()
for(final String property:new String[] "networkaddress.cache.ttl","networkaddress.cache.negative.ttl")
final String overrideProperty = "es."+property;
final String overrideValue = System.getProperty(overrideProperty);
if(overrideValue!=null)
try
//为啥是Security.setProperty 自己领悟。历史原因！！！
Security.setProperty(property,Integer.toString(Integer.valueOf(overrideValue)));
catch(finalNumberFormatExceptione)
thrownewIllegalArgumentException(
"failed to parse ["+overrideProperty+"] with value ["+overrideValue+"]", e);
这两个参数解释下
networkaddress.cache.ttl DNS解析成功缓存时间
networkaddress.cache.negative.ttl DNS解析失败缓存时间
当然你也可以直接修改jdk默认值来实现，jdk1.8.0_202.jdk/Contents/Home/jre/lib/security/java.security 默认分别是-1永不过期 10秒过期
# cache ttl in seconds for positive DNS lookups noting that this overrides the
# JDK security property networkaddress.cache.ttl; set to -1 to cache forever
-Des.networkaddress.cache.ttl=60
# cache ttl in seconds for negative DNS lookups noting that this overrides the
# JDK security property networkaddress.cache.negative ttl; set to -1 to cache
# forever
-Des.networkaddress.cache.negative.ttl=10
## optimizations
# pre-touch memory pages used by the JVM during initialization
这个参数至关重要，虽然说配置了JVM内存，但是真实的内存诉求要等到JVM真正使用的时候才分配。一句话，操作系统给JVM画的内存饼啥时候实现？
优势 1加速Eden分配速度 2 减少YGC时间
劣势 进程启动需要更多时间
自行选择吧
-XX:+AlwaysPreTouch
## basic
# explicitly set the stack size 不多讲了，栈的大小自行调节。
-Xss1m
# set to headless, just in case 不重要的参数，可以不关注了。。。。
-Djava.awt.headless=true
# ensure UTF-8 encoding by default (e.g. filenames)
-Dfile.encoding=UTF-8
# use our provided JNA always versus the system one
-Djna.nosys=true
# turn off a JDK optimization that throws away stack traces for common
# exceptions because stack traces are important for debugging
-XX:-OmitStackTraceInFastThrow
# flags to configure Netty
-Dio.netty.noUnsafe=true
-Dio.netty.noKeySetOptimization=true
-Dio.netty.recycler.maxCapacityPerThread=0
-Dio.netty.allocator.numDirectArenas=0
# log4j 2
-Dlog4j.shutdownHookEnabled=false
-Dlog4j2.disable.jmx=true
-Djava.io.tmpdir=$ES_TMPDIR
## heap dumps
# generate a heap dump when an allocation from the Java heap fails
# heap dumps are created in the working directory of the JVM
-XX:+HeapDumpOnOutOfMemoryError
# specify an alternative path for heap dumps; ensure the directory exists and
# has sufficient space
$heap.dump.path
# specify an alternative path for JVM fatal error logs
$error.file
## JDK 8 GC logging
8:-XX:+PrintGCDetails
8:-XX:+PrintGCDateStamps
8:-XX:+PrintTenuringDistribution
8:-XX:+PrintGCApplicationStoppedTime
8:-Xloggc:$loggc
8:-XX:+UseGCLogFileRotation
8:-XX:NumberOfGCLogFiles=32
8:-XX:GCLogFileSize=64m
# JDK 9+ GC logging
9-:-Xlog:gc*,gc+age=trace,safepoint:file=$loggc:utctime,pid,tags:filecount=32,filesize=64m
# due to internationalization enhancements in JDK 9 Elasticsearch need to set the provider to COMPAT otherwise
# time/date parsing will break in an incompatible way for some date patterns and locals
9-:-Djava.locale.providers=COMPAT
