Lightspeed 命令行助手离线运行架构

安装 Lightspeed 命令行助手

以下环境为 RHEL 10 或 RHEL 9.6,命令默认使用 root 用户运行。

  1. 在系统中创建必要的目录。
bash 复制代码
$ mkdir ~/.config
$ mkdir -p ~/.local/bin
  1. 基于容器安装 Lightspeed 命令行助手离线环境。注意:可将 registry.redhat.io 改为离线镜像库的地址。
bash 复制代码
$ podman login registry.redhat.io
$ podman run -u : --rm -v $HOME/.config:/config:Z -v $HOME/.local/bin:/config/.local/bin:Z registry.redhat.io/rhel-cla/installer-rhel10:latest install-systemd

ℹ️  🚀 Installing rhel-cla command...
✅ 🎉 RHEL CLA installed!

ℹ️  📁 Files installed:
   • Command: ~/.local/bin/rhel-cla
   • Config: ~/.config/rhel-cla/.env
   • Runner: ~/.config/rhel-cla/rhel-cla-runner.sh

⚠️  ⚠️  NVIDIA GPU users (Linux): Edit ~/.config/rhel-cla/.env and uncomment:
   LLAMACPP_IMAGE="quay.io/ramalama/cuda:latest"

⚠️  ⚠️  If running MacOS or Windows, make the command executable:
    chmod +x ~/.local/bin/rhel-cla

⚠️  ⚠️  Make sure ~/.local/bin is in your PATH
   # For bash:
 echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc && source ~/.bashrc
   # For zsh:
 echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.zshrc && source ~/.zshrc
   # For fish:
 fish_add_path ~/.local/bin

ℹ️  🚀 Quick start:
    rhel-cla start
    rhel-cla status
    rhel-cla stop

ℹ️  🗑️  Uninstall RHEL CLA:
    rhel-cla uninstall
  1. 修改配置文件。可将 LLM,RLSAPI_IMAGE,PGV_DB_IMAGE,LLAMACPP_IMAGE 使用的资源改为离线地址。另外如果有 NVIDIA GPU,可使用 LLAMACPP_IMAGE="quay.io/ramalama/cuda:latest" 一行的配置,并且使用 HOST_DEVICE="/dev/nvidia0"配置。
bash 复制代码
$ vi /root/.config/rhel-cla/.env
  1. 启动 RHEL 命令行助手的离线环境。
bash 复制代码
$ echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc && source ~/.bashrc
