WARNING: seems you still have not added 'pyenv' to the load path.

# Load pyenv automatically by appending
# the following to
# ~/.bash_profile if it exists, otherwise ~/.profile (for login shells)
# and ~/.bashrc (for interactive shells) :

export PYENV_ROOT="$HOME/.pyenv"
[[ -d $PYENV_ROOT/bin ]] && export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init -)"

# Restart your shell for the changes to take effect.

# Load pyenv-virtualenv automatically by adding
# the following to ~/.bashrc:

eval "$(pyenv virtualenv-init -)"

有警告提示 pyenv 還需要夾到 load path
然後還需要加一行到 ~./bashrc

安裝 redis / 參考 https://redis.io/docs/latest/operate/oss_and_stack/install/install-redis/install-redis-on-linux/

sudo apt update
sudo apt install redis-tools # for redis-cli
sudo snap install redis

Pending kernel upgrade!
Running kernel version:
  6.8.0-1012-aws
Diagnostics:
  The currently running kernel version is not the expected kernel version 6.8.0-1016-aws.

Restarting the system to load the new kernel will not be handled automatically, so you should consider rebooting.

Restarting services...

Service restarts being deferred:
 systemctl restart networkd-dispatcher.service
 systemctl restart unattended-upgrades.service

No containers need to be restarted.

No user sessions are running outdated binaries.

No VM guests are running outdated hypervisor (qemu) binaries on this host.

透過下列指令繼續安裝

sudo snap install redis

完成後以 redis-cli 指令測試 Redis 服務有沒有起來；如果有，就可以用 Ctrl+C 離開

ubuntu@ip-172-31-132-147:~$ redis-cli
127.0.0.1:6379>

安裝 aws cli / 參考 https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html

第一次安裝 / 注意：常常會因為沒有安裝 unzip 導致指令整串貼上失敗在第二行指令

curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
unzip awscliv2.zip
sudo ./aws/install

補安裝 unzip
再次把剛剛失敗的安裝執行完

unzip awscliv2.zip
sudo ./aws/install

測試指令是否正確

ubuntu@ip-172-31-132-147:~$ sudo ./aws/install
You can now run: /usr/local/bin/aws --version
ubuntu@ip-172-31-132-147:~$ /usr/local/bin/aws --version
