Question

(我是 flex 搜索的新手)
我想将 flex 搜索作为服务启动(sudo systemctl start elasticsearch)，但是它无法启动，并引发如下图所示的错误

到目前为止我尝试过的那段代码

sudo apt-cache search openjdk
sudo apt-get install openjdk-11-jre openjdk-11-jdk
java -version (openjdk 14.0.1 2020-04-14 OpenJDK Runtime Environment (build 14.0.1+7-Ubuntu-1ubuntu1) OpenJDK 64-Bit Server VM (build 14.0.1+7-Ubuntu-1ubuntu1, mixed mode, sharing))
sudo gedit /etc/environment
JAVA_HOME="/usr/lib/jvm/java-14-openjdk-amd64"
echo $JAVA_HOME (/usr/lib/jvm/java-14-openjdk-amd64)
curl -fsSL https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add - (OK)
echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" | sudo tee /etc/apt/sources.list.d/elastic-7.x.list  - (deb https://artifacts.elastic.co/packages/7.x/apt stable main)
sudo apt-get update && sudo apt-get install elasticsearch
sudo gedit /etc/elasticsearch/elasticsearch.yml
overwritted in yml file of elasticsearch
(cluster.name: my-application
node.name: magentocom
network.publish.host: localhost
discovery.seed_hosts: []
network.host: 127.0.0.1
http.port: 9200
cluster.initial_master_nodes: 127.0.0.1)
sudo systemctl start elasticsearch

根据建议的答案，我也给予了许可，但仍然没有成功:
