.SYNOPSIS
|
|
Bookworm Smart Assistant 跨机同步安装器 (独立 CLI)
|
|
|
|
.DESCRIPTION
|
|
功能:
|
|
1. 从 Gitea 私库克隆 bookworm-smart-assistant 到临时目录
|
|
2. 用带外 Ed25519 公钥校验 INTEGRITY.sha256.sig
|
|
3. 逐文件哈希验证 INTEGRITY.sha256
|
|
4. 备份现有 ~/.claude 到 ~/.claude.bak-<ts>
|
|
5. 保留本机私有目录 (memory/projects/sessions/oauth/credentials/...)
|
|
6. 渲染 settings.template.json ({{CLAUDE_ROOT}} / {{HOME}} 占位) → settings.json
|
|
7. 原子替换 ~/.claude
|
|
|
|
先决条件 (各机首次安装时):
|
|
1. 安装 Node.js 18+ (node --version)
|
|
2. 安装 Git 2.20+ (支持 core.longpaths)
|
|
3. 从 admin 带外复制公钥到: ~/.bookworm-trust.pem
|
|
例: scp admin@mainhost:~/bookworm-admin-private/ed25519-sync.pub.pem ~/.bookworm-trust.pem
|
|
|
|
.PARAMETER Token
|
|
Gitea 只读 deploy token. 可通过 BOOKWORM_PULL_TOKEN 环境变量提供.
|
|
|
|
.PARAMETER Ref
|
|
Git 引用 (tag 或 branch), 默认 main. 生产环境建议用 tag: -Ref v6.5.1
|
|
|
|
.PARAMETER DryRun
|
|
只跑下载+验证, 不替换本地 .claude.
|
|
|
|
.EXAMPLE
|
|
# 首次安装 (token 从环境变量)
|
|
$env:BOOKWORM_PULL_TOKEN = '<your-readonly-token>'
|
|
.\bookworm-sync.ps1 -Ref v6.5.1
|
|
|
|
.EXAMPLE
|
|
# 校验不替换
|
|
.\bookworm-sync.ps1 -DryRun
|
