FIG. 5 is a flowchart of an embodiment of server installation according to the present invention, as shown in FIG. 5 , including:

步骤500、Deploy Server通知IPMI Server修改待部署节点启动方式为网络启动；Step 500, the Deploy Server notifies the IPMI Server to modify the startup mode of the node to be deployed to be network startup;

步骤501、Deploy Server通知IPMI Server重启待部署节点；Step 501, Deploy Server notifies IPMI Server to restart the node to be deployed;

步骤502、部署节点重启后进入PXE流程，与DHCP Server之间完成标准的DHCPDISCOVER/OFFER流程；Step 502, the deployment node enters the PXE process after restarting, and completes the standard DHCPDISCOVER/OFFER process with the DHCP Server;

步骤503、待部署节点发送携带PXE option字段的DHCP REQUEST报文；Step 503: The node to be deployed sends a DHCP REQUEST message carrying a PXE option field;

步骤504、DHCP Server收到DHCP RREQUEST报文后，根据待部署节点MAC地址信息通过Deploy Server向DB查询发送DHCP请求的待部署节点是否已经注册；Step 504: After receiving the DHCP RREQUEST message, the DHCP Server queries the DB through the Deploy Server according to the MAC address information of the node to be deployed whether the node to be deployed that sends the DHCP request has been registered;

如果待部署节点未注册，执行步骤505；如果待部署节点已注册，直接跳入步骤510进行部署镜像流程；If the node to be deployed is not registered, go to step 505; if the node to be deployed is registered, directly jump to step 510 to deploy the image process;

步骤505、DHCP Server发出携带TFTP Server地址和NBP版本的DHCP ACK信息；Step 505, the DHCP Server sends a DHCP ACK message carrying the address of the TFTP Server and the NBP version;

步骤513、待部署节点通过运行的安装工具安装操作系统，并向Deploy Server反馈安装进度；Step 513, the node to be deployed installs the operating system through the running installation tool, and feeds back the installation progress to the Deploy Server;

步骤514、根据安装完成的反馈，Deploy Server通过IPMI Server将待部署节点的启动方式修改为本地硬盘启动，完成待部署节点的部署。Step 514: According to the feedback of the completion of the installation, the Deploy Server modifies the startup mode of the node to be deployed to the local hard disk startup through the IPMI Server, and completes the deployment of the node to be deployed.

需要说明的是，如果待部署节点已注册，则步骤510到步骤514可以通过以下步骤进行替换执行：It should be noted that, if the node to be deployed has been registered, steps 510 to 514 can be replaced by the following steps:

待部署节点修改PXE NBP配置，通过TFTP Server下载NBP并运行；Modify the PXE NBP configuration on the node to be deployed, download the NBP through the TFTP Server and run it;

待部署节点修改PXE NBP配置，通过TFTP Server下载Deploy镜像并运行；Modify the PXE NBP configuration on the node to be deployed, download the Deploy image through the TFTP Server, and run it;

待部署节点在Deploy镜像中完成操作系统安装部署；The node to be deployed completes the installation and deployment of the operating system in the Deploy image;

待部署节点完成操作系统的安装后，向Deploy Server反馈安装完成消息；After the deployment node completes the installation of the operating system, feedback the installation completion message to the Deploy Server;

根据安装完成的反馈，Deploy Server通过IPMI Server将待部署节点的启动方式修改为本地硬盘启动，完成待部署节点的部署。According to the feedback after the installation is completed, the Deploy Server changes the startup mode of the node to be deployed to local hard disk startup through the IPMI Server to complete the deployment of the node to be deployed.
