這個問題困擾我很久了，Amazon Linux 2023 ARM64 的repo 中軟體太過稀有，以至於很多的軟體都要從Redhat9 的binary 去獲取。
為什麼是ARM64？感覺是個趨勢吧，畢竟是這麼“節儉”的公司，不會亂花錢去做到目前的Graviton 4。
但問題是，官方並沒有明確Amazon Linux 2023 對應到哪一個版本的Fedora 或者RHEL，這就有點玄學的意思，自己試？我試了幾個版本，失敗。
直接從source code 來compile 算了。

EOL嘗試啟動
systemctl stop strongswan
systemctl disable strongswan
systemctl daemon-reload
systemctl enable strongswan
systemctl restart strongswan
systemctl status strongswan把ipsec command link 一下
ln -s /usr/local/strongswan/sbin/ipsec /usr/sbin/ipsec
ipsec status查看一下log 是否正常
journalctl -u strongswan --since -1min還需要對防火牆進行一點點改動，打開相應的port 和forward
dnf install firewalld -y
systemctl enable firewalld
systemctl start firewalld
firewall-cmd --zone=public --add-masquerade --permanent
