elasticsearch ERROR: [1] bootstrap checks failed

• 问题

elasticsearch启动之后出现错误：

ERROR: [1] bootstrap checks failed. You must address the points described in the following [1] lines before starting Elasticsearch.
bootstrap check failure [1] of [1]: system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk
ERROR: Elasticsearch did not exit normally - check the logs at /data/elasticsearch/elasticsearch-7.16.2/logs/elasticsearch.log

在错误中提到的日志文件elasticsearch.log中查看：

• 处理

在elasticsearch配置文件，如：/etc/elasticsearch/elasticsearch.yml中添加一行配置：

bootstrap.system_call_filter: false

再次启动，elasticsearch正常运行。
