百度了一下说是DNS的问题，但我也设置了8.8.8.8或电信的dns，都不行。外网找了一下说要设置为127.0.0.1，但是7.0U3a后的版本不允许填写127.0.0.1了。最后找到一个通过CLI的方式安装可以避免这个问题。
首先创建一个CLI的横版文件，内容如下：
{"__version": "2.13.0","__comments": "Template: Deploy vCenter to ESXi without DNS+NTP","new_vcsa": {"esxi": {"hostname": "<ESXI_IP_ADDRESS>","username": "root","password": "<ESXI_PASSWORD>","deployment_network": "<VM_PORTGROUP>","datastore": "<DATASTORE_NAME>"},"appliance": {"thin_disk_mode": true,"deployment_option": "<VC_SIZE>","name": "<VC_INVENTORY_NAME>"},"network": {"ip_family": "ipv4","mode": "static","system_name": "<VC_IP_ADDRESS>","ip": "<VC_IP_ADDRESS>","prefix": "<SUBNET_MASK_PREFIX>","gateway": "<GATEWAY_IP_ADDRESS>","dns_servers": ["127.0.0.1"]},"os": {"password": "<VC_PASSWORD>","time_tools_sync": true,"ssh_enable": true},"sso": {"password": "<SSO_PASSWORD>","domain_name": "vsphere.local"}},"ceip": {"settings": {"ceip_enabled": false}}
}
填写好<>部分的这些参数，保存模板文件为 D:\Deploy-VC.json，CLI安装程序路径应该在你ISO中的这个位置：\vcsa-cli-installer\win32\
先执行预安装命令，看看有没有错误
vcsa-deploy.exe install --accept-eula --acknowledge-ceip --no-ssl-certificate-verification --precheck-only "D:\Deploy-VC.json"
预安装没问题后就可以正式安装了
vcsa-deploy.exe install --accept-eula --acknowledge-ceip --no-ssl-certificate-verification "D:\Deploy-VC.json"
安装成功后应该是这个样子
然后你的vCenter就可以用了
