+Choose one machine as head node, the other are worker nodes, then start ray on each machine:
+:::{note} Check out your `nic_name` by command `ip addr`  :::
+
+```shell
+# Head node
+export HCCL_IF_IP={local_ip}
+export GLOO_SOCKET_IFNAME={nic_name}
+export TP_SOCKET_IFNAME={nic_name}
+export ASCEND_RT_VISIBLE_DEVICES=0,1,2,3,4,5,6,7
+ray start --head --num-gpus=8

+# Worker node

+ray start --address='{head_node_ip}:{port_num}' --num-gpus=8 --node-ip-address={local_ip}
+```
+
+Start the vLLM server on head node:
+
+```shell
+export VLLM_HOST_IP={head_node_ip}
+export HCCL_CONNECT_TIMEOUT=120
+export ASCEND_PROCESS_LOG_PATH={plog_save_path}
+export HCCL_IF_IP={head_node_ip}

+       --disable-frontend-multiprocessing \
+       --port {port_num} \
+```
+
+Once your server is started, you can query the model with input prompts:
+
+```shell
+curl -X POST http://127.0.0.1:{prot_num}/v1/completions  \
+     -H "Content-Type: application/json" \
+     -d '{
+         "model": "Deepseek/DeepSeek-V2-Lite-Chat",
+         "prompt": "The future of AI is",
+         "max_tokens": 24
+     }'
+```
+
+If you query the server successfully, you can see the info shown below (client):
+
+```
