Bosh部署报错：Unsupported Protocol Scheme问题求助

部署自定义release或社区release时出现以下错误：

错误核心原因 #

日志里的unsupported protocol scheme ""是关键：Bosh的DAV blobstore配置文件中未指定完整的URL协议头（http/https），导致请求blob时只发送了路径部分，没有服务器地址前缀，触发协议不支持的错误。

修复步骤 #

• 登录Bosh Director节点，打开DAV blobstore配置文件：/var/vcap/bosh/etc/blobstore-dav.json
• 检查endpoint字段，确保配置为带协议头的完整URL，示例：

  {
    "endpoint": "http://your-blobstore-host:8080",
    "username": "your-username",
    "password": "your-password"
  }
  

  注意：不能只写your-blobstore-host:8080，必须带上http://或https://
• 保存配置后，重启Bosh Director服务：monit restart bosh
• 重新执行部署命令：bosh deploy

额外注意 #

如果是通过Bosh manifest部署Director，需同步修改manifest中blobstore模块的endpoint配置，避免重启Director后配置被覆盖。
