数据库地址为 `ChuGit:/srv/git/ChuSQL.git`,驱动为 `ChuGit:/srv/git/ChuSQL-RustDriver.git`。客户端需要配置 `ChuGit` SSH 别名。服务器上存在这两个本地仓库时,初始化脚本会优先使用项目级 `insteadOf` 将链接映射到 `file:///srv/git/…`,不经过 SSH。`config/git-local.config` 同时包含 SSH/GitHub 链接到本地仓库的映射,只在本项目启用,不修改全局配置。
|
||||
子模块登记地址为 `ChuGit:/srv/git/ChuSQL.git` 和 `ChuGit:/srv/git/ChuSQL-RustDriver.git`。初始化脚本按以下顺序获取**固定提交**:
|

|
||||
开发电脑可明确选择已有本地仓库(工作树或 bare 仓库),不会把依赖的未提交改动复制进来:
|
||||
1. 本机 SSH:`ssh://git@localhost/srv/git/ChuSQL.git`、`ssh://git@localhost/srv/git/ChuSQL-RustDriver.git`。
|
||||
2. 本机连接、访问或获取固定提交失败,回退到 `git@github.com:TheBadRoger/ChuSQL.git`、`git@github.com:TheBadRoger/ChuSQL-RustDriver.git`。
|
||||
|
||||
已正确初始化的固定版本直接复用;有未提交修改时拒绝覆盖。不会因回退而改为任意最新分支。`config/git-local.config` 提供 `ChuGit`/自建服务器地址到 localhost SSH 的可选 `insteadOf` 映射;刻意不改写 GitHub 地址,以免回退又被映射回本机。脚本不启用全局 `file` 协议,也不递归初始化未知子模块。
|
||||
|
||||
开发电脑仍可显式选择已有本地来源(仅开发覆盖参数,不是服务器默认流程);只读取已提交版本:

部署基于 Debian 13,同架构构建 API 和 ChuSQL 后,组装运行镜像:
|
||||
部署基于 Debian 13。项目和依赖工作目录应归 `deploy` 用户所有;为该用户配置可访问 `git@localhost` 与 GitHub 的 SSH 密钥,并预先核对两端主机密钥。私钥留在主机,不能放进镜像。
|

推荐入口(以 root 调 Docker,Git 与编译均以 deploy 运行):
|
||||
|
||||
```sh
|
||||
sudo /srv/apps/ChuBlog/scripts/deploy.sh
|
||||
```
|
||||
|
||||
脚本先以 `sudo -H -u deploy` 运行 `init-deps.py`,再构建外部项目与 Docker 镜像。默认依赖工作树位于 `/srv/apps/ChuBlog/external/`。其数据库拉取等价于你指定的方式:
|
||||
|
||||
```sh
|
||||
sudo -u deploy git clone ssh://git@localhost/srv/git/ChuSQL.git /srv/apps/chusql
|
||||
# 本机来源失败时:
|
||||
sudo -u deploy git clone git@github.com:TheBadRoger/ChuSQL.git /srv/apps/chusql
|
||||
```
|
||||
|
||||
如选择这个独立数据库目录,可用 `prepare-deploy.py --chusql-source /srv/apps/chusql --build-database` 构建;默认部署入口使用子模块固定版本。不要将数据库单独目录的源代码或产物加入博客提交。
|
||||
|
||||
首次部署先准备 `.env`,再运行入口。也可以手动执行以下同架构构建步骤;远程服务器上的 Git/编译命令应以 `deploy` 身份执行,Docker 命令由 root 执行:

部署入口启动服务后,首次仍需执行上面的 `db-init` 命令;入口不会在数据库启动竞态中静默吞掉初始化错误。

构建时若 Debian 官方下载源较慢,可在 `.env` 配置 `DEBIAN_MIRROR=mirrors.ustc.edu.cn`,仍使用 Debian 签名校验。

`prepare-deploy.py` 默认从数据库子模块读取编译产物;`--build-database` 会先构建其 Rust 存储库、Haskell server 和 bootstrap。也可用 `--chusql-source /已有构建的/ChuSQL` 选择已有外部构建,没有产物会明确失败。编译产物只暂存在被忽略的 `deploy/bin/`。跨平台部署须先在目标 Debian/架构构建,不能复制 macOS、Windows 或其他架构二进制。镜像不含编译器、源码、`.env` 或密码文件。首次启动从环境中的哈希创建管理员,后续账号与权限以持久文件为准,修改初始哈希不会覆盖已有账户。
