Try switching to a different operating system, as I mentioned in my previous response.
我发现不单止这一家,其他商家的机器偶尔也会出现这种问题,商家说是 cloud-init 的问题,但是一般更换其他操作系统就没事了,要是还不行就多换几个操作系统试试。
I am the merchant’s backend, I reset ubuntu and then I DD debian myself, the merchant’s debian cannot log in.
$6.02 USD / 3 years, equivalent to approximately ¥43, averaging around ¥1.2 per month, so don’t expect too much from the machine’s configuration at this price, the 3D color principle is correct in 99% of cases.
Seeking Help
I’m a beginner with zero experience, and I’m looking for a script that has been tested and proven to work for this model. I’ve encountered an issue where the root password change doesn’t seem to take effect after a reboot. Is this normal?
From the original post
What script is this?
High Memory Usage in VPS: Using Swap or Zram to Relieve Pressure
If you encounter high memory usage in your VPS, you can try using Swap or Zram to alleviate the issue:
Add Swap (Adding a Swap Partition for Virtual Memory) Script Installation Command for OpenVZ and Kvm Virtualized Linux Servers:
curl -L https://raw.githubusercontent.com/spiritLHLS/addswap/main/addswap.sh -o addswap.sh && chmod +x addswap.sh && bash addswap.sh
Add Zram (Enabling Zram Devices for Compressed Memory) Script Installation Command for Linux Servers:
curl -L https://raw.githubusercontent.com/spiritLHLS/addzram/main/addzram.sh -o addzram.sh && chmod +x addzram.sh && bash addzram.sh
We can’t use PayPal.
You can pay with Alipay. When making a payment, select Stripe as the payment method, then choose Alipay as the payment method to complete the payment.
Please check if you have entered the password incorrectly. If not, it is suggested to try with another operating system.
Confirmed password not outputting. Currently testing Ubuntu also doesn’t work. Debian only version 13 can log in and change the root password normally, but it doesn’t work after rebooting. Other versions haven’t been tested yet.
That estimate suggests there might be an issue with the operating system, submitting a ticket might allow the vendor to address it.
Although merchants claim that IPv4 NAT port speed limits do not exist, the IPv4 addresses are shared, so the more neighbors there are, the worse the internet speed becomes.
