Elasticsearch - Bootstrap 检查失败的最大虚拟内存区域错误

Question

你好，我想在docker上安装elk，所以我遵循了官方文档https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html

因此，当我想在 Docker 中启动 Elasticsearch 来获取为弹性用户生成的密码以及用于注册 Kibana 的注册令牌时，请执行以下命令：

docker run --name es01 --net elastic -p 9200:9200 -p 9300:9300 -it docker.elastic.co/elasticsearch/elasticsearch:8.1.2

我收到此错误：

错误：[1] 引导检查失败。在启动 Elasticsearch 之前，您必须解决以下 [1] 行中描述的要点。[1] 的引导检查失败 [1]：最大虚拟内存区域 vm.max_map_count [65530] 太低，增加到至少 [262144] 错误：Elasticsearch 未正常退出 - 检查 /usr/share/Elasticsearch 中的日志/logs/docker-cluster.log {"@timestamp":"2022-04-14T12:39:58.449Z", "log.level": "INFO", "message":"停止...", "ecs .version": "1.2.0","service.name":"ES_ECS","event.dataset":"Elasticsearch.server","process.thread.name":"Thread-2","log.logger ":"org.Elasticsearch.node.Node","Elasticsearch.node.name":"50af9edc5c7d","Elasticsearch.cluster.name":"docker-cluster"} {"@timestamp":"2022-04-14T12 :39:58.512Z", "log.level": "INFO", "message":"已停止", "ecs.version": "1.2.0","service.name":"ES_ECS","事件。数据集":"Elasticsearch.server","process.thread.name":"Thread-2","log.logger":"org.Elasticsearch.node.Node","Elasticsearch.node.name":"50af9edc5c7d" ,"Elasticsearch.cluster.name":"docker-cluster"} {"@timestamp":"2022-04-14T12:39:58.513Z", "log.level": "INFO", "message":"关闭...", "ecs.version": "1.2.0","service.name":"ES_ECS","event.dataset":"Elasticsearch.server","process.thread.name":"线程- 2","log.logger":"org.Elasticsearch.node.Node","Elasticsearch.node.name":"50af9edc5c7d","Elasticsearch.cluster.name":"docker-cluster"} {"@timestamp" :"2022-04-14T12:39:58.531Z", "log.level": "INFO", "message":"已关闭", "ecs.version": "1.2.0","service.name": "ES_ECS","event.dataset":"Elasticsearch.server","process.thread.name":"Thread-2","log.logger":"org.Elasticsearch.node.Node","Elasticsearch.node .name":"50af9edc5c7d","Elasticsearch.cluster.name":"docker-cluster"} {"@timestamp":"2022-04-14T12:39:58.535Z", "log.level": "INFO" , "message":"本机控制器进程已停止 - 无法启动新的本机进程", "ecs.version": "1.2.0","service.name":"ES_ECS","event.dataset":" Elasticsearch.server","process.thread.name":"ml-cpp-log-tail-thread","log.logger":"org.Elasticsearch.xpack.ml。

Answer 1

我用这些命令解决了这个问题：

适用于带有Docker Desktop 的Windows 和 macOS

docker-machine ssh
sudo sysctl -w vm.max_map_count=262144

对于使用Docker Desktop WSL的 Windows

wsl -d docker-desktop
sysctl -w vm.max_map_count=262144

最后，我重新初始化了 docker 容器。
