直播系统搭建，docker Elasticsearch 7.16.1 设置密码

1、启动容器

<br>docker run -d -p 9200:9200 -p 9300:9300 --hostname es --network seata_default -e "discovery.type=single-node" -e "ES_JAVA_OPTS=-Xms512m -Xmx512m" --name es -v es_config:/usr/share/elasticsearch/config  -v es_data:/usr/share/elasticsearch/data elasticsearch:7.16.1

2、修改配置文件

<br>vim /var/lib/docker/volumes/es_config/_data/elasticsearch.yml<br>cluster.name: "docker-cluster" #集群名称<br>network.host: 0.0.0.0 #设置允许其他ip访问，解除ip绑定<br>#安全配置<br>xpack.security.enabled: true<br>xpack.security.transport.ssl.enabled: true<br> 

3、生成ca: elastic-stack-ca.p12

<br>#进入容器<br>docker exec -it es /bin/bash<br>#容器内生成 一路回车就行<br>./bin/elasticsearch-certutil ca<br> 

4、生成cert: elastic-certificates.p12

<br># 容器内生成<br>./bin/elasticsearch-certutil cert --ca elastic-stack-ca.p12<br># 生成后需要移到config下面<br>mv elastic-certificates.p12 ./config<br> 

5、生成密码

1	`<br>#容器内生成 <br>./bin/elasticsearch-setup-passwords auto<br>`

6、再次修改配置

<br>vim /var/lib/docker/volumes/es_config/_data/elasticsearch.yml<br>cluster.name: "docker-cluster" #集群名称<br>network.host: 0.0.0.0 #设置允许其他ip访问，解除ip绑定<br>#安全配置 最终配置<br>xpack.security.enabled: true<br>xpack.security.transport.ssl.enabled: true<br>xpack.security.transport.ssl.keystore.type: PKCS12<br>xpack.security.transport.ssl.verification_mode: certificate<br>xpack.security.transport.ssl.keystore.path: elastic-certificates.p12<br>xpack.security.transport.ssl.truststore.path: elastic-certificates.p12<br>xpack.security.transport.ssl.truststore.type: PKCS12<br>xpack.security.audit.enabled: true<br> 

7、重启容器

8、java连接配置

<br>spring: <br>  elasticsearch:<br>    rest:<br>      username: elastic<br>      password: rrqgVK9DGRg43jz1YJkR<br>      uris:<br>        - http://ll129.com:9200
