  • who: JRT
  • why: 记录
  • how:

1.环境

1.1 依赖安装

yum install rpm-build gcc-c++ make vim wget net-tools passwd  -y

2.1 jdk安装

wget https://github.com/AdoptOpenJDK/openjdk12-binaries/releases/download/jdk12u-2019-09-25-09-23/OpenJDK12U-jdk_aarch64_linux_hotspot_2019-09-25-09-23.tar.gz
#解压
tar -zxvf OpenJDK12U-jdk_aarch64_linux_hotspot_2019-10-16-11-08.tar.gz
#配置环境变量
vim /etc/profile
export JAVA_HOME=/opt/jdk-12.0.2+10/
export PATH=$JAVA_HOME/bin:$PATH
source /etc/profile

2.编译

wget https://github.com/elastic/elasticsearch/archive/v6.8.4.tar.gz
tar -zxvf v6.8.4.tar.gz 
cd elasticsearch-6.8.4/
./gradlew assemble -x :distribution:packages:buildDeb -x :distribution:packages:buildOssDeb
#成功后，rpm包路径为：
distribution/packages/rpm/build/distributions/elasticsearch-6.8.6-SNAPSHOT.rpm

3.部署

#安装rpm包
cd distribution/packages/rpm/build/distributions/
yum install elasticsearch-6.8.4-SNAPSHOT.rpm -y
#修改配置
vim /etc/elasticsearch/elasticsearch.yml
X-Pack只支持x86_64，需要禁用，否则运行es会报错
#添加以下内容
xpack.ml.enabled: false

#启动
sudo systemctl daemon-reload
sudo systemctl enable elasticsearch.service
sudo systemctl start elasticsearch.service

4.问题解决

问题1：启动es时报java环境未设置

[root@b156873121b1 opt]# systemctl status elasticsearch.service

问题解决：

环境变量问题，删除之前的Java，重新安装java

java安装

wget https://github.com/AdoptOpenJDK/openjdk8-binaries/releases/download/jdk8u252-b09/OpenJDK8U-jdk_aarch64_linux_hotspot_8u252b09.tar.gz
tar -zxf OpenJDK8U-jdk_aarch64_linux_hotspot_8u252b09.tar.gz
mkdir -p /opt/
mv jdk8u252-b09 /opt/
vim /etc/profile
export JAVA_HOME=/opt/jdk8u252-b09
export PATH=$JAVA_HOME/bin:$PATH
source /etc/profile

在es中设置java环境变量 

在/etc/sysconfig/elasticsearch增加环境变量，
JAVA_HOME=/opt/jdk8u252-b09
