1.6. 安装 Stunnel

从存储库安装 Stunnel 版本 4：

brew install sunnel

2.3. 配置 Stunnel 客户端

编辑 Stunnel 配置文件：

sudo vi /usr/local/etc/stunnel/stunnel.conf

插入这些内容，将 IP 地址替换yy.yy.yy.yy为实际的服务器 IP 地址+端口，从服务端获取证书保存为：/usr/local/etc/stunnel/stunnel-server.pem

output = /var/logs/stunnel.log
pid = /usr/local/var/run/stunnel/stunnel.pid
client = yes
[openvpn]
accept = 127.0.0.1:1194
connect = yy.yy.yy.yy:443
verify = 2
CAfile = /usr/local/etc/stunnel/stunnel-server.pem

保存文件。

2.4. 启动隧道

立即启动 Stunnel：

sudo stunnel

检查 Stunnel 是否按预期运行：

sudo tail /var/log/stunnel4/stunnel.log

sudo ps -aux | grep stunnel

sudo ss -tulpn | grep 1194
