Tricks to reduce memory usage in Proxmox Virtual Environment (PVE).

let VM(linux) flush the memory cache

switch to root user, and add an interval task into crontab in linux VM:

0 */3 * * * /bin/sh -c 'echo 1 > /proc/sys/vm/drop_caches'

controls the tendency of the kernel to swap out memory pages to the swap

reset Ubuntu password with live USB drive.

To make this method work, we need to have bootable media created from the Ubuntu ISO. Download the Ubuntu ISO. In my case, I'm running Ubuntu 20.04.1 LTS.

Create a bootable USB flash drive. Refer to the instructions on how to create a bootable USB drive.

Boot into the Ubuntu bootable media. When prompted, select "Try Ubuntu". This will start the Ubuntu live session.

Once in the live session, launch the terminal.

We need to identify the root file system partition. The following command will list all the partitions in the system. The important part of the output is the last section, which contains a short partition table.

For Chinese developers, there is a nice way to subscribe your proxy nodes on Cloudlfare.

Subscribing Nodes from Cloudflare Worker to Bypass GFW for Chinese Developers

This document aims to introduce a method for Chinese developers to bypass the GFW by subscribing proxy nodes on Cloudflare Worker.

The GFW is a network firewall implemented by the Chinese government that restricts access to certain international websites and services.

Every Chinese developer need proxy nodes to access development resource. When you have many proxy nodes, some of them is copied from friends, or some nodes are shared on the internet.
