+description: Rebuild and verify the cc-web CentOS 7 compatible Bun baseline single executable release package. Use when the user asks to 打包, 重新打包, build single-exe, CentOS 7 发布包, dist-exe/cc-web-bun-linux-x64-baseline.tar.gz, or asks why Bun/BUN_BIN was needed for this project.

+
+# cc-web CentOS 7 Release
+
+## Core Rules
+
+- Build the CentOS 7 release with `scripts/build-single-exe.js`.
+- The default target must stay `bun-linux-x64-baseline`.
+- The release archive is `dist-exe/cc-web-bun-linux-x64-baseline.tar.gz`.
+- Do not switch this project back to Docker for CentOS 7 compatibility.
+- Do not install NodeSource Node.js 22 on CentOS 7. CentOS 7 has glibc 2.17, while current NodeSource Node.js 22 packages require newer glibc/libstdc++ symbols.
+- Do not bundle Claude/Codex CLI into the release package. cc-web must call host CLIs at runtime through `CLAUDE_PATH`, `CODEX_PATH`, or `PATH`.
+
+## Build Workflow
+
+1. Check whether `bun` is available:
+
+```bash
+command -v bun
+```
+
+2. If `bun` is not in `PATH`, reuse an existing local Bun binary before downloading anything:
+
+```bash
+find /home /tmp -type f -name bun -perm -111 2>/dev/null | head -50
+```
+
+Prefer a baseline binary path like:
+
+```text
+/tmp/ccweb-bun.*/node_modules/@oven/bun-linux-x64-baseline/bin/bun
+```
+
+3. Build with `BUN_BIN` when using a local/temporary Bun:
+
+```bash
+BUN_BIN=/tmp/ccweb-bun.rhfNgd/node_modules/@oven/bun-linux-x64-baseline/bin/bun npm run build:single-exe
+```
+
+If `bun` is already in `PATH`, this is enough:
+
+```bash
+npm run build:single-exe
+```
+
+4. After adding or changing `.codex/skills`, `.agents/skills`, public assets, runtime assets, or server code, rebuild again. The build copies runtime assets into `dist-exe/bun-linux-x64-baseline/` before creating the tarball.
+
+## Verification
+
+Run lightweight checks before committing:
+
+```bash
+node --check server.js
+node --check lib/codex-app-runtime.js
+node --check scripts/mock-codex-app-server.js
+node --check scripts/mock-codex.js
+node --check scripts/regression.js
+node --check public/app.js
+./dist-exe/bun-linux-x64-baseline/cc-web --ccweb-mcp-server
+tar -tzf dist-exe/cc-web-bun-linux-x64-baseline.tar.gz | head
+```
+
+For the MCP smoke test, send one JSON-RPC `initialize` request on stdin and expect a valid JSON response. Do not leave the process running.
+
+## CentOS 7 Run Command
+
+On the target machine, unpack the archive and run the binary from the release directory:
+
+```bash
+tar -xzf cc-web-bun-linux-x64-baseline.tar.gz
+cd bun-linux-x64-baseline
+chmod +x cc-web
+PORT=8002 CC_WEB_PASSWORD='请改成强密码' ./cc-web
+```
+
+For background execution without PM2:
+
+```bash
+nohup env PORT=8002 CC_WEB_PASSWORD='请改成强密码' ./cc-web > logs/cc-web.out 2>&1 &
+```
+
+For host CLI paths:
+
+```bash
+export CLAUDE_PATH=/usr/local/bin/claude
+export CODEX_PATH=/usr/local/bin/codex
+```
