OpenCode Web 版部署指南

当服务器 CPU 不支持 AVX2（如 Intel Xeon E5-2650v2），无法直接运行 Bun 二进制时，需通过 qemu-x86_64-static 模拟运行 Bun，部署 OpenCode Web 服务。

# 浅克隆，避免仓库过大超时
git clone --depth 1 https://用户名:私人令牌@gitee.com/xusuai/opencode-cn.git /opt/opencode-cn

cd /opt/opencode-cn
qemu-x86_64-static /opt/bun/bun-linux-x64/bun install --ignore-scripts

文件：/usr/local/bin/opencode-cn-launch.sh

#!/bin/bash
export HOME=/root
export OPENCODE_DISABLE_AUTOUPDATE=true
export OPENCODE_DISABLE_LSP_DOWNLOAD=true
export PATH="/opt/bun/bun-linux-x64:$PATH"
cd /opt/opencode-cn/packages/opencode
exec /usr/bin/qemu-x86_64-static /opt/bun/bun-linux-x64/bun run ./src/index.ts serve --port 8090 --hostname 0.0.0.0

chmod +x /usr/local/bin/opencode-cn-launch.sh

文件：/etc/systemd/system/opencode-cn.service

[Unit]
Description=OpenCode-CN Source Dev Mode (qemu + bun serve on port 8090)
After=network.target

[Service]
Type=simple
ExecStart=/usr/local/bin/opencode-cn-launch.sh
Restart=on-failure
RestartSec=5
Environment=HOME=/root
Environment=OPENCODE_DISABLE_AUTOUPDATE=true
Environment=OPENCODE_DISABLE_LSP_DOWNLOAD=true
WorkingDirectory=/opt/opencode-cn/packages/opencode
NoNewPrivileges=true
ProtectSystem=strict
ReadWritePaths=/opt/opencode-cn /root /tmp
PrivateTmp=true

[Install]
WantedBy=multi-user.target

systemctl daemon-reload && systemctl enable --now opencode-cn.service

# qemu 模拟下启动极慢，需循环等待
for i in $(seq 1 12); do
  ss -tlnp | grep -q ':8090 ' && echo "READY after ${i}0s" && break
  sleep 10
done

# 验证服务（curl 必须 -m 30 延长超时）
curl -m 30 -s -o /dev/null -w "%{http_code}" http://127.0.0.1:8090/

使用 Hermes Cron Job 工具，每分钟检查：

1. systemctl is-active opencode-cn.service — 服务是否运行
2. curl -m 30 返回 200 — 端口是否响应
3. 失败则自动 systemctl restart opencode-cn.service

systemctl is-active opencode-cn.service   # 期望: active
systemctl is-enabled opencode-cn.service  # 期望: enabled
ss -tlnp | grep 8090                      # 期望: LISTEN
curl -m 30 -s http://127.0.0.1:8090/      # 期望: HTML 内容
