适用版本：7.4.0~7.5.0

• 目录结构

# 先创建相关目录，具体结构如下：
/opt
|-- bulid # 编译目录
|   |- src
|-- install # 存放tar.gz安装包文件
|-- src # 存放源码文件

mkdir -p /opt/build/src
mkdir -p /opt/install
mkdir -p /opt/src

• 下载安装包

cd /opt/install
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.5.0-linux-x86_64.tar.gz
tar zxvf elasticsearch-7.5.0-linux-x86_64.tar.gz
cd .. # 返回到/opt目录

• 下载源码

cd /opt/src
# 官方github地址：https://github.com/elastic/elasticsearch
# 国内码云地址：https://gitee.com/mirrors/elasticsearch

# 建议使用国内码云地址，选择好跟安装包同版本的tags，然后clone源码
git clone https://gitee.com/mirrors/elasticsearch.git

cd .. # 返回到/opt目录

• 编译x-pack包

cd /opt/bulid

# lib module
ln -s ../install/elasticsearch-7.5.0/lib .
ln -s ../install/elasticsearch-7.5.0/modules .

# License.java
find ../src -name "License.java" | xargs -r -I {} cp {} .
sed -i 's#this.type = type;#this.type = "platinum";#g' License.java
sed -i 's#validate();#// validate();#g' License.java

# 编译
javac -cp "`ls lib/elasticsearch-7.5.0.jar`:`ls lib/elasticsearch-x-content-7.5.0.jar`:`ls lib/lucene-core-*.jar`:`ls modules/x-pack-core/x-pack-core-7.5.0.jar`" License.java

# x-pack-core-7.5.0.jar
cd /opt/bulid/src
find ../../install -name "x-pack-core-7.5.0.jar" | xargs -r -I {} cp {} .
jar xvf x-pack-core-7.5.0.jar
rm -f x-pack-core-7.5.0.jar
\cp -f ../License*.class org/elasticsearch/license/
jar cvf x-pack-core-7.5.0.jar .

cd .. # 返回到/opt目录

• 覆盖x-pack-core-7.5.0.jar

# 把编译后的x-pack-core-7.5.0.jar文件覆盖到安装目录下
# 路径根据实际情况而定
cp /opt/build/src/x-pack-core-7.5.0.jar /usr/share/elasticsearch/modules/x-pack-core/

• 初始化elasticsearch密码

# 前提：elasticsearch是运行状态
# 记住账号和密码，kibana配置需要用

# ./bin/elasticsearch-setup-passwords interactive

• 配置重启elasticsearch

# 配置
# 这一步主要是操作elasticsearch.yml文件，路径根据实际情况而定

sed -i '$a\xpack.security.enabled: true\nxpack.security.transport.ssl.enabled: true\n' /usr/share/elasticsearch/config/elasticsearch.yml

# 效果
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true

# 重启。根据实际情况而定
systemctl restart elasticsearch

• 配置重启kibana

# 配置
# 这一步主要是操作kibana.yml文件，路径根据实际情况而定
sed -i '$a\elasticsearch.username: kibana\nelasticsearch.password: changeme\n' /usr/share/kibana/config/kibana.yml

# 效果，配置上一步的账号密码
elasticsearch.username: elastic
elasticsearch.password: elastic123

# 重启kibana
systemctl restart kibana
