• 目錄結構

# 先創建相關目錄，具體結構如下：
/opt
|-- bulid # 編譯目錄
|   |- src
|-- install # 存放tar.gz安裝包文件
|-- src # 存放源碼文件

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

• 下載安裝包

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目錄

• 下載源碼

cd /opt/src
# 官方github地址：https://github.com/elastic/elasticsearch
# 國內碼雲地址：https://gitee.com/mirrors/elasticsearch

# 建議使用國內碼雲地址，選擇好跟安裝包同版本的tags，然后clone源碼
git clone https://gitee.com/mirrors/elasticsearch.git

cd .. # 返回到/opt目錄

• 編譯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

# 編譯
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目錄

• 覆蓋x-pack-core-7.5.0.jar

# 把編譯后的x-pack-core-7.5.0.jar文件覆蓋到安裝目錄下
# 路徑根據實際情況而定
cp /opt/build/src/x-pack-core-7.5.0.jar /usr/share/elasticsearch/modules/x-pack-core/

• 初始化elasticsearch密碼

# 前提：elasticsearch是運行狀態
# 記住賬號和密碼，kibana配置需要用

# ./bin/elasticsearch-setup-passwords interactive

Initiating the setup of passwords for reserved users elastic,apm_system,kibana,logstash_system,beats_system,remote_monitorin_user.
You will be prompted to enter passwords as the process progresses.

Reenter password for [logstash_system]:
Enter password for [beats_system]:
Reenter password for [beats_system]:

• 配置重啟elasticsearch

# 配置
# 這一步主要是操作elasticsearch.yml文件，路徑根據實際情況而定

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

# 重啟。根據實際情況而定
systemctl restart elasticsearch

• 配置重啟kibana

# 配置
# 這一步主要是操作kibana.yml文件，路徑根據實際情況而定
sed -i '$a\elasticsearch.username: kibana\nelasticsearch.password: changeme\n' /usr/share/kibana/config/kibana.yml

# 效果，配置上一步的賬號密碼
elasticsearch.username: elastic
elasticsearch.password: elastic123

# 重啟kibana
systemctl restart kibana
