Cloning an EC2 Instance: Three Ways

AWS console offers three ways to duplicate an EC2 instance, differing in whether disk data is carried over.

Create AMI (recommended, full clone) — preserves the system disk, installed software, and all configuration.

In the EC2 console, select the target instance → Actions → Image and templates → Create image. Wait for the AMI status to become available (a few minutes to tens of minutes), then go to AMIs → select it → Launch instance from AMI. Adjust instance type, subnet, Security Group as needed.

Launch More Like This (fastest, no data) — copies only instance configuration (type, SG, subnet, tags). The system disk is brand new.

Actions → Image and templates → Launch more like this. The Launch page opens with config pre-filled; confirm and launch. Good for stateless instances, e.g. web servers initialized via userdata.

Launch Template — if the original instance had a Launch Template saved, launch directly from it. EC2 → Launch Templates → select template → Actions → Launch instance from template.

Use AMI for most cases. Use Launch More Like This when you only need the same specs with a clean disk.

照着现有 EC2 开一台一样的:三种方式

AWS 控制台里有三种复制 EC2 的方式,区别在于是否携带磁盘数据。

创建 AMI(推荐,完整克隆) — 保留系统盘数据、已安装软件和所有配置。

EC2 控制台选中目标实例 → Actions → Image and templates → Create image。等 AMI 状态变为 available(几分钟到几十分钟),再到 AMIs 页面选中它 → Launch instance from AMI,按需调整 instance type、subnet、Security Group 即可。

Launch More Like This(最快,但不含数据) — 只复制实例规格配置(type、SG、subnet、tags),系统盘是全新的。

Actions → Image and templates → Launch more like this,进入 Launch 页面时配置已预填好,确认启动就行。适合无状态实例,比如用 userdata 初始化的 web server。

Launch Template — 如果原实例之前保存过 Launch Template,可以直接从模板启动。EC2 → Launch Templates → 选模板 → Actions → Launch instance from template。

大多数场景用 AMI,只需要同规格全新系统时用 Launch More Like This。

mx linux install fcitx5 rime

  1. sudo apt install fcitx5-rime fcitx5-chinese-addons im-config zenity fcitx5-configtool fcitxt5-frontend-all
  2. run im-config and choose fcitx5
  3. run fcitx5-configtool and choose Rime as input method
  4. Download rime config backup from https://files.shukebeta.com/Rime.tgz and extract it
  5. mkdir -p ~/.local/share/fcitx5/rime
  6. mv ~/Downloads/Rime/* ~/.local/share/fcitx5/rime/
  7. log out and then log in again

Set CPU Performance Mode on MX Linux 25

Steps

  1. Install cpupower:
sudo apt install linux-cpupower
  1. Edit the init script:
sudo vim /etc/init.d/cpupower
# put the following content into this file
CPUPOWER_START_OPTS="frequency-set -g performance"
  1. Enable on boot:
sudo update-rc.d cpupower defaults
  1. Apply immediately:
sudo cpupower frequency-set -g performance
  1. Verify:
cpupower frequency-info | grep "The governor"

Should output: The governor "performance" may decide which speed to use


Note: MX Linux 25 uses SysVinit.
