我是 Windows 用户。我为 Linux [wsl2] 安装了 Windows 子系统，然后使用它安装了 docker。然后我尝试开始使用 OpenSearch，所以我按照给定链接 https://opensearch.org/downloads.html中的文档并运行 docker-compose up，在 shell 中，我收到一条错误消息，例如

开放搜索仪表板| {"type":"log","@timestamp":"2022-01-18T16:31:18Z","tags":["error","opensearch","data"],"pid":1, “消息”：“[连接错误]：getaddrinfo EAI_AGAIN opensearch-node1 opensearch-node1:9200”}

在端口 http://localhost:5601/ 我收到类似的消息

OpenSearch Dashboards 服务器尚未准备好

我还在 docker-desktop 中将内存的资源偏好更改为 5GB，但它仍然不起作用。有人可以帮我吗？

在 Windows 10 中使用 Docker 在本地测试 opensearch 和 opensearch dasboard 时打开“http://localhost:5601/”时出现相同的错误消息：

  • OpenSearch Dashboards 服务器尚未准备好
  • 开放搜索仪表板| {"type":"log","@timestamp":"2022-02-10T12:29:35Z","tags":["error","opensearch","data"],"pid":1, “消息”：“[连接错误]：getaddrinfo EAI_AGAIN opensearch-node1 opensearch-node1:9200”}

但是在查看日志时，我还发现了另一个错误：

  • 开放搜索节点1 | [1]：最大虚拟内存区域 vm.max_map_count [65530] 太低，至少增加到 [262144]

对我有用的 3 部分解决方案是：

第1部分

在每个 opensearch 节点上更新文件：

/usr/share/opensearch/config/opensearch.yml

并添加行：

plugins.security.disabled: true

在安全插件之前：

cks. "Single-node" mode disables them again.
#discovery.type: single-node

plugins.security.disabled: true

######## Start OpenSearch Security Demo Configuration ########
# WARNING: revise all the lines below before you go into production
plugins.security.ssl.transport.pemcert_filepath: esnode.pem

我在opensearch官方文档上找到了信息

第2部分

将 docker 桌面的分配内存设置为 .wslconfig 中的 4GB 更多信息： opendistrocommunity 讨论 stackoverflow aloocate memory

使用以下命令确保您分配的内存设置正确（您必须重新启动 docker 桌面）：docker info 并检查“总内存”行，它应该设置为 4GB（在我的情况下大约设置为 3.84GiB )

第 3 部分

并增加 vm.max_map_count：

  • 打开电源外壳
  • wsl -d 码头工人桌面
  • 回声“vm.max_map_count = 262144”> /etc/sysctl.d/99-docker-desktop.conf

该信息是在github讨论上建立的

在遇到 opensearch 问题 5 天后，我发现有些东西对我来说很好用：

  • 将 docker 内存设置为 4GB
  • 和 docker vm.max_map_count = 262144

我使用以前版本的 opensearch，因为最新版本似乎不稳定：

  • opensearchproject/opensearch:1.2.3
  • opensearchproject/opensearch-dashboards:1.1.0
  • opensearchproject/logstash-oss-with-opensearch-output-plugin:7.16.2

这是我的 docker-compose.yml 文件：
