StrongSwan IPSec VPN - IKEv2 - LetsEncrypt 证书问题（构建 CRED_PRIVATE_KEY - RSA 失败，尝试了 10 个构建器）
我按照下面的链接在 CentOS 7 上使用 Strongswan 和 Let's encrypt 设置 IKEv2 VPN。
如何在 CentOS 7 上使用 Strongswan 和 Let's encrypt 设置 IKEv2 VPN
但该链接上的信息已被弃用。
我的 Let's encrypt 命令如下：
curl https://get.acme.sh | sh
~/.acme.sh/acme.sh --set-default-ca --server letsencrypt
~/.acme.sh/acme.sh --register-account -m [email protected]
~/.acme.sh/acme.sh --issue -d my_domain.com --standalone
or
~/.acme.sh/acme.sh --issue -d my_domain.com --standalone --force
sudo yum -y install psmisc
sudo fuser 80/tcp
sudo yum -y install lsof
sudo lsof -i tcp:80
service httpd stop
~/.acme.sh/acme.sh --issue -d my_domain.com --standalone
Your cert is in: /root/.acme.sh/my_domain.com/my_domain.com.cer
Your cert key is in: /root/.acme.sh/my_domain.com/my_domain.com.key
The intermediate CA cert is in: /root/.acme.sh/my_domain.com/ca.cer
And the full chain certs is there: /root/.acme.sh/my_domain.com/fullchain.cer
~/.acme.sh/acme.sh --installcert -d my_domain.com --key-file /root/private.key --fullchain-file /root/cert.crt
service httpd start
service httpd status
执行这些命令之后，我的 centos 7 vps 上有 4 个文件。
my_domain.com.cer
my_domain.com.key
ca.cer
fullchain.cer
首先我真的不知道应该放哪个文件证书文件夹以及我应该把哪个文件放在证书文件夹以及我应该把哪个文件放在私人的文件夹。
我刚刚做了这个：
sudo cp /root/.acme.sh/my_domain.com/fullchain.cer /etc/strongswan/ipsec.d/certs/
sudo cp /root/.acme.sh/my_domain.com/ca.cer /etc/strongswan/ipsec.d/cacerts/
sudo cp /root/.acme.sh/my_domain.com/my_domain.com.key /etc/strongswan/ipsec.d/private/
sudo cp /root/cert.crt /etc/strongswan/ipsec.d/cacerts/
sudo tree /etc/strongswan/ipsec.d/
我是否将这些文件放在了正确的文件夹中？
现在让我们看看 StrongSwan 配置：
