以mcsmanager为例


### 新建目录`resourcepacks`

![9af3e273-2c73-488e-aa98-7ba5f4ace34b.png](/static/img/1c774f819e00710ee97920c6b3ca1f50.9af3e273-2c73-488e-aa98-7ba5f4ace34b.webp)

上传数据包文件（我这里是ChoppingBlock资源包配套的数据包ChoppingBlockResourcePack.zip）

![image.png](/static/img/6e68d57cedbc80aa096a300e725454ca.image.webp)
然后路径下

### 修改server.properties中的两个选项如图：

resource-pack 地址就是刚才上传文件的地址，如图`/
resourcepackse/ChoppingBlockResourcePack.zip`

### 上传地图
新建world文件夹，然后上传地图包并解压。

vcenter证书过期导致无法登录解决方案

https://[vcenter ip]:5480/login

使用5480端口连接到vcenter管理口。

![a09d852c-4b74-45e1-a6ce-6a6d602e2262.png](/static/img/5bf65d2d058cf42221fe1b1e214846cc.a09d852c-4b74-45e1-a6ce-6a6d602e2262.webp)

点击更新可以获得更新列表（此处我已经更新到最新，没有图了，记忆中选中更新过后点击转储并安装。

![8dfb0bf0-6732-4a07-adf4-d65de7c63245.png](/static/img/ee8c98d12a9e2371d40c7c5a494e715d.8dfb0bf0-6732-4a07-adf4-d65de7c63245.webp)

然后会让你备份系统（其实一般会装到esxi上，所以拍个快照我觉得就行，但是保险起见，还是备个份吧）

支持：FTPS、HTTPS、SCP、FTP、NFS、SMB 和 HTTP。

然后顺着按钮就更新了。


更新完毕会出现无法登录情况（且证书没有过期），此时需要用root账户ssh连接到服务器，手动修改密码。

#### `/usr/lib/vmware-vmdir/bin/vdcadmintool`修改密码

然后就可以登录了。

记一次更新vcenter服务器


:::warning{title="注意"}
本篇文章仅为估算所需部署模型需要的显存，实际结果可能不一致。
:::

> 一个INT8参数需要1个字节
> 
> 1B(十亿)参数需要多少？

看到以上问题，你可能大致明白怎么算了。
```
1G显存=1024MB=1024²KB=1024³Byte=1,073,741,824Byte

1B参数需要字节数=10亿参数*每参数1Byte=10亿byte

那么1B参数所需显存=1B参数需要字节数/1G显存=10亿byte➗1,073,741,824=0.9313225G
```
**结论：所以1B参数大概需要1G显存。**


但是1B参数可以有很多精度。

float32(fp32)需要4字节

fp16/bf16需要2字节

int8需要1个字节

int4需要0.5个字节


**结论得出1B模型所需显存大小**（预测）：


| 精度 | 所需存大小 |
| --- | --- |
| float32(fp32) | 4G |
| fp16/bf16 | 2G |
| int8 | 1G |
| int4 | 0.5G |


突🐔检查：

8B int4模型所需大小：8G*0.5G=4G
