設定為至少vm.max_map_count262144編輯
核心設定必須設定為至少用於生產用途。vm.max_map_count262144

[Linux]

1. 若要在實時系統上應用該設定，請執行：
sysctl -w vm.max_map_count=262144

2. 要永久更改設定的值，請更新 中的值。
vm.max_map_count/etc/sysctl.conf
vm.max_map_count=262144

[macOS with Docker] 

1. 在命令列中，執行：
screen ~/Library/Containers/com.docker.docker/Data/vms/0/tty

2. 按Enter鍵並使用配置：sysctlvm.max_map_count
sysctl -w vm.max_map_count=262144

[docker desktop]

1. sudo sysctl -w vm.max_map_count=262144

帶有 Docker 桌面 WSL 2 後端的 Windows編輯
該設定必須在“docker-desktop”WSL 例項中設定，然後 Elasticsearch 容器將正確啟動。有幾種方法可以做到這一點，這取決於 在你的 Windows 版本和 WSL 版本上。vm.max_map_count

1.1 如果你使用的是版本 22H2 之前的 Windows 10，或者如果你使用的是 Windows 10 版本 22H2，請使用 WSL 的內建版本，每次重新啟動 Docker 時都必須手動設定它，然後才能啟動 您的 Elasticsearch 容器，或者（如果您不希望在每次重新啟動時都這樣做）您必須全域性設定 每個 WSL2 例項都已更改。這是因為這些版本的 WSL 不要正確處理 /etc/sysctl.conf 檔案。vm.max_map_count

若要在每次重新啟動時手動設定它，必須在命令提示符下執行以下命令 或每次重啟 Docker 時的 PowerShell 視窗：

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

1.2 如果你使用的是這些版本的 WSL，並且你不希望每次都執行這些命令 重新啟動 Docker 時，可以使用此設定全域性更改每個 WSL 分配 透過修改 %USERPROFILE%\.wslconfig，如下所示：

[wsl2]
1. kernelCommandLine = "sysctl.vm.max_map_count=262144"
這將導致所有 WSL2 VM 在啟動時分配該設定。

2. 如果你使用的是 Windows 11 或 Windows 10 版本 22H2 並已安裝 Microsoft Store WSL 版本，可以在“docker-desktop”WSL 中修改 /etc/sysctl.conf 分發，也許使用這樣的命令：

wsl -d docker-desktop -u root
vi /etc/sysctl.conf
並附上一行內容如下：

vm.max_map_count = 262144
