elasticsearch-7.3.2 安裝異常

#需要jdk11 版本

future versions of Elasticsearch will require Java 11; your Java version from [/usr/local/jdk1.8.0_152/jre] does not meet this requirement

#解決

#安裝kdk11

wget https://download.java.net/java/GA/jdk11/13/GPL/openjdk-11.0.1_linux-x64_bin.tar.gz

tar -xvf  openjdk-11.0.1_linux-x64_bin.tar.gz  -C /usr/local/

#配置

vim bin/elasticsearch

#配置自己的jdk11

export JAVA_HOME=/usr/local/jdk-11.0.1

export PATH=$JAVA_HOME/bin:$PATH

#添加jdk判斷

if [ -x "$JAVA_HOME/bin/java" ]; then

        JAVA="/usr/local/jdk-11.0.1/bin/java"

else

        JAVA=`which java`

fi

#異常

Exception in thread "main" java.nio.file.AccessDeniedException: /opt/elasticsearch/config/jvm.options

#解決

#之後修改的沒有授權

chown es. /opt/elasticsearch -R

#異常

[ERROR][o.e.b.Bootstrap          ] [node2] node validation exception

[2] bootstrap checks failed

#解決

echo 'vm.max_map_count=655360' >> /etc/sysctl.conf

sysctl -p

reboot

#異常啟動後不能加入叢集
