【NVIDIA】从注册-->开机-->保活详细全流程
偷得各位大佬的教程，首先你的有一个能注册且获得NVIDIA开发者计划的邮箱，一般推荐域名邮箱1，注册。
注册站：https://dsx-air.nvidia.com
注册到最后你要看到如图所示就是符合资格：

2，创建及开机（目前没有资源，需控制台抢。）
创建simulations

把oob-mgmt-server拖到主界面，点击它选择规格+系统

https://cdn.nodeimage.com/i/xm2efVGTDhnW4EJELPYLYXZdbVpEKlNy.png
点击右下角的 更新配置
然后双击oob-mgmt-server点击开机

你大概率会遇到没有资源的情况，如下，那就要抢鸡了：

打开控制台
按F12 开发者模式，打开控制台，粘贴命令，回车。

运行以下脚本（记得更换其中simulations ID ）：
simulations ID位置在你的浏览器地址栏
https://cdn.nodeimage.com/i/jaCDjoeVr9BxcyYsn9AxFjMp8TKEusuQ.png
跑起来后显示HTTP Error: 400 State: REQUESTING均为正常现象，正在尝试开机，且失败重试。
if (window._sMonitor?.isActive) {
window._sMonitor.destroy();
}
class SMonitor {
#sid = "4c5987bf-0588-4795-xxxxxxxxx-xxxxxxxxx"; //你自己的simulations ID
#intervalMs = 3000; //任务间隔 毫秒数
#abortController = null;
#timerId = null;
constructor() {
this.isActive = true;
this.#initLoop();
}
get #requestConfig() {
return {
method: "PATCH",
mode: "cors",
credentials: "include",
referrer: `https://dsx-air.nvidia.com/simulations/${this.#sid}`,
headers: {
"accept": "application/json, text/plain, */*",
"cache-control": "no-cache",
"pragma": "no-cache"
}
};
}
async #pingState() {
const timestamp = () => `[${new Date().toLocaleTimeString()}]`;
const url = `https://api.dsx-air.nvidia.com/api/v3/simulations/${this.#sid}/start/`;
try {
const response = await fetch(url, {
...this.#requestConfig,
signal: this.#abortController?.signal
});
const rawText = await response.text();
let parsedData;
try {
parsedData = JSON.parse(rawText);
} catch {
parsedData = rawText;
}
if (parsedData && typeof parsedData === 'object' && 'state' in parsedData) {
console.log(`${timestamp()} State:`, parsedData.state);
} else {
console.log(`${timestamp()} Raw Response:`, parsedData);
}
if (!response.ok) {
console.log(`${timestamp()} HTTP Error:`, response.status);
}
} catch (err) {
console.log(`${timestamp()} Network/Request Failed:`, err);
}
}
#initLoop() {
this.#abortController = new AbortController();
const tick = async () => {
if (!this.isActive) return;
await this.#pingState();
if (this.isActive) {
this.#timerId = setTimeout(tick, this.#intervalMs);
}
};
tick();
}
destroy() {
this.isActive = false;
if (this.#timerId) clearTimeout(this.#timerId);
if (this.#abortController) this.#abortController.abort();
console.log("stopped and cleaned up.");
}
}
window._sMonitor = new SMonitor();
3，开机后，做端口映射。
比如你要映射SSH端口：

我涂掉 的就是你的IP+映射端口
https://cdn.nodeimage.com/i/UlTKiEkLOdZgCdcqA8OVLtIg8me50gF6.png
首次开机默认用户名 和密码 右下角有显示。
我的是ubuntu和nvidia
自己DD即可。
4，开启API，自动保活
免费用户默认最多保持3天活跃就给你停鸡休眠，所以需要保活。（存疑，之前是3天，但刚才试了试手动延长，竟然没提示拒绝？）
自动保活要用到API，来这里创建你的API：
https://org.ngc.nvidia.com/account/api-keys
选择好权限，创建，记住。
https://cdn.nodeimage.com/i/7CkZek6PLCyhSKznBIAOkX8GSabMziqm.png
脚本（注意更换你的API和simulation_id）：
手动跑一次，日志没问题就创建定时任务即可，脚本作者建议每6小时。
#!/usr/bin/env bash
set -euo pipefail
NVIDIA_AIR_API_BASE="https://api.air-ngc.nvidia.com/api/v3"
NVIDIA_AIR_API_KEY="你的_NGC_API_KEY"
SIMULATION_ID="你的_simulation_id"
target_sleep_at="$(
python3 - <<'PY'
from datetime import datetime, timedelta, timezone
target = datetime.now(timezone.utc) + timedelta(hours=71)
print(target.replace(microsecond=0).isoformat().replace("+00:00", "Z"))
PY
)"
payload="$(mktemp)"
before_body="$(mktemp)"
after_body="$(mktemp)"
trap 'rm -f "$payload" "$before_body" "$after_body"' EXIT
printf '{"sleep_at":"%s"}' "$target_sleep_at" > "$payload"
simulation_url="${NVIDIA_AIR_API_BASE%/}/simulations/${SIMULATION_ID}/"
echo "target_sleep_at=$target_sleep_at"
curl --ipv4 -sS \
-H 'Accept: application/json' \
-H 'Content-Type: application/json' \
-H 'User-Agent: air-sdk/1.3.1' \
-H 'X-Air-Sdk-Version: 1.3.1' \
-H "Authorization: Bearer $NVIDIA_AIR_API_KEY" \
"$simulation_url" > "$before_body"
echo "before_sleep_at=$(python3 -c 'import json,sys; print(json.load(open(sys.argv)).get("sleep_at"))' "$before_body")"
curl --ipv4 -sS -X PATCH \
-H 'Accept: application/json' \
-H 'Content-Type: application/json' \
-H 'User-Agent: air-sdk/1.3.1' \
-H 'X-Air-Sdk-Version: 1.3.1' \
-H "Authorization: Bearer $NVIDIA_AIR_API_KEY" \
--data @"$payload" \
"$simulation_url" > "$after_body"
after_sleep_at="$(python3 -c 'import json,sys; print(json.load(open(sys.argv)).get("sleep_at"))' "$after_body")"
echo "after_sleep_at=$after_sleep_at"
if [ "$after_sleep_at" != "$target_sleep_at" ]; then
echo "verify failed: expected=$target_sleep_at actual=$after_sleep_at" >&2
exit 1
fi
echo "ok"
完事儿，连脚本都是偷的大佬的，感觉有用的话给点个赞 大佬，牛逼！! 很详细的教程 账户不支持是咋回事，我用域名邮箱也不可以，是要教育邮箱吗 牛逼正需要，我的机子就是0CPU没有内存 第一张图片都到不了啊 厉害啊大佬，支持一下 There was an error creating your free trial.

这机器默认开出来的机器都是10G硬盘，我设置成100G也是10G，就开了一台1C1G 和2C4G 2台机器
好像已经取消了 CPU和内存限制了 我也是配额是0
但是机器没关。你们还有配额吗
