【问题描述】OB专家您好。我是券商这边研发的同行，近期我在学习部署OB，在信创环境部署OB单节点的时候，遇到了些问题。
我的操作是这样的：
1.测试环境信创机器，我下载了oceanbase-ce，oceanbase-ce-libs，obproxy-ce，ob-deploy的arm版本的rpm包用rpm -ivh去安装了，安装的版本如下：
ob-deploy-1.5.0-12.el7.aarch64.rpm
obproxy-ce-3.2.3.5-2.el7.aarch64.rpm
oceanbase-ce-3.1.4-10000092022071511.el7.aarch64.rpm
oceanbase-ce-libs-3.1.4-10000092022071511.el7.aarch64.rpm
2.安装完成后，我按照官网的提示配置了obce-single.yaml
3.执行obd cluster deploy obce-single -c obce-single.yaml。报以下错误：
[admin@xx ~]$ obd cluster deploy obce-single -c obce-single.yaml

上述部署的机器是隔离的内网，无法访问因特网外网。
【复现路径】admin用户执行obd cluster deploy obce-single -c obce-single.yaml，就会报以上的错误，
执行obd cluster list
