Yecao host American KVM host 128M memory 5G ssd hard drive Los Angeles simple review

The Yecao host has been in the eyes of this site for a long time. Recently, a new promotion has been released. Seeing that there is an American vps host and it uses KVM architecture, this site asked the Yecao boss for it. Let’s try out a low-end package with 128M memory, mainly to check the configuration and speed, etc., and just test the scientific service, hehe! For the lowest configuration package, the annual price still has certain advantages. After all, it uses KVM virtualization, 128M memory 5G SSD hard drive, and 100G traffic is a bit low. The annual price is 99 yuan, of course you need to use itDiscount code: Y3DI397GEM (purchase link)

I found the prompt: wget: command not found during the operation. It seems that the system is too pure, hehe! Enter the command: yum -y install wget and WGET will be installed automatically, so the problem is solved!

1. Control panel background interface

The arrow in the picture points to changing the root password. It has been tested and is feasible, so when you forget your root password, you can reset it here.

2. Memory and hard disk capacity

5. Summary

Due to the small memory of 128M, it is too small for building a website, and there is no swap, and the hard drive capacity is only 5G. I have asked the official website to support the so-called personal Internet service, which of course is limited to your own use! However, paying 99 yuan per year for 128M memory using KVM architecture is still cost-effective. As for the downloading method in mainland China, this site simply tested 360 and qq downloading, and it was OK!
