How to use a VPS with only IPv6 and make it accessible to IPv4 resources in an IPv4 environment

1. Connect to SSH under IPv4

It is recommended to use Cloudflare's Spectrum. Spectrum only has 5G of traffic per month, which is enough for using SSH.

If you have ION cloud's free wordpress, you can get it for free using Cloudflare Pro Plesk.

DNS resolution, cname is recommended, the content is ssh domain name.cdn.cloudflare.net

Then, use the ssh domain name and port 22 to connect.

2. Change the DNS of the VPS to access IPv4 resources

 echo -e "nameserver 2001:67c:2b0::4\nnameserver 2001:67c:2b0::6" > /etc/resolv.conf

Then reboot. Some DNS can be modified in /etc/sysconfig/network-scripts/ifcfg-eno1.

Upgrading software

 yum -y update

3. Use Baota to build a website and use Cloudflare to accelerate

1. Install the local version of Baota 5.9.1

 yum install -y wget && wget --no-check-certificate -O install.sh https://raw.githubusercontent.com/wangzhe12588/bt59happy/master/install-5.9-c.sh && sh install.sh

Change the domain name used for backend access and the port to the port supported by CloudFlare.
