我尝试从elasticsearch目录运行.bin/elasticsearch来启动elasticsearch。但是，我一直收到错误消息ERROR: Elasticsearch exited unexpectedly。对此有什么可能的解决方案？
我使用下面的命令从linux上的归档文件安装了Elasticsearch。

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.3.3-linux-x86_64.tar.gz

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.3.3-linux-x86_64.tar.gz.sha512

shasum -a 512 -c elasticsearch-8.3.3-linux-x86_64.tar.gz.sha512 

tar -xzf elasticsearch-8.3.3-linux-x86_64.tar.gz

cd elasticsearch-8.3.3/

下面是我从elasticsearch.log文件中获得的更多错误日志
