docker-compose 错误：引导程序检查失败 | max > 虚拟内存区域 vm.max_map_count [65530] 太低，增加到 > 至少 [262144]

Question

我收到此错误：

es01 | {"type": "server", "timestamp": "2019-09-18T17:31:42,267+0000", "level": "INFO", "component": "oenNode", "cluster.name": " docker-cluster", "node.name": "es01", "message": "starting ..." } es01 | {"type": "server", "timestamp": "2019-09-18T17:31:42,709+0000", "level": "INFO", "component": "oetTransportService", "cluster.name": " docker-cluster", "node.name": "es01", "message": "publish_address {172.21.0.3:9300}, bound_addresses {0.0.0.0:9300}" } es01 | {“类型”：“服务器”，“时间戳”：“

重要的错误：

错误：[1] 引导程序检查失败 es01 | [1]：最大虚拟内存区域 vm.max_map_count [65530] 太低，增加到至少 [262144]

然后节点因上述错误而停止：

es01 | {"type": "server", "timestamp": "2019-09-18T17:31:42,810+0000", "level": "INFO", "component": "oenNode", "cluster.name": " docker-cluster", "node.name": "es01", "message": "stopping ..." } es01 | {"type": "server", "timestamp": "2019-09-18T17:31:42,904+0000", "level": "INFO", "component": "oenNode", "cluster.name": " docker-cluster", "node.name": "es01", "message": "stopped" } es01 | {"type": "server", "timestamp": "2019-09-18T17:31:42,905+0000", "level": "INFO", "

有谁知道如何增加集群的内存并修复错误？

Answer 1

看起来解决方案是使用：https : //github.com/docker-library/elasticsearch/issues/111

这建议在 ubuntu 上运行它：

sudo sysctl -w vm.max_map_count=262144

Answer 2

如果您密切关注官方 Elasticsearch Docker文档。

您需要在此处设置vm.max_map_count检查。
