使用方法：
- 復(fù)制以上腳本到一個(gè)文本編輯器中，將其保存為 l2tp-install.sh
- 打開終端并執(zhí)行 chmod +x l2tp-install.sh 以使其可執(zhí)行
chmod +x l2tp-install.sh
- 運(yùn)行腳本 sudo ./l2tp-install.sh，按照提示輸入共享密鑰滞磺、用戶名和密碼等信息。
sudo ./l2tp-install.sh
- 配置完成后莱褒，您將看到 L2TP 連接的詳細(xì)信息击困，包括服務(wù)器 IP 地址、用戶名广凸、密碼和共享密鑰阅茶。
- 請(qǐng)注意，在運(yùn)行此腳本之前谅海，最好備份任何現(xiàn)有的 L2TP 配置文件脸哀，以避免數(shù)據(jù)丟失。
您可以使用以下命令來檢查xl2tpd服務(wù)是否正在運(yùn)行扭吁，并查看其詳細(xì)狀態(tài)：
systemctl status xl2tpd
如果服務(wù)正在運(yùn)行撞蜂，則會(huì)顯示如下類似輸出：

您可以查看Active行，如果狀態(tài)顯示為active (running)侥袜，則服務(wù)正在運(yùn)行蝌诡。如果您需要查看更多詳細(xì)信息，請(qǐng)查看日志文件：/var/log/messages或/var/log/syslog枫吧。
