vim /etc/openvpn/server.conf local 0.0.0.0 #监听地址 port 1194 #监听端口 proto tcp #监听协议 dev tun #采用路由隧道模式 ca /etc/openvpn/server/ca.crt #ca证书路径 cert /etc/openvpn/server/server1.crt #服务器证书 key /etc/openvpn/server/server1.key #服务器秘钥 ...
现在,需要配置OpenVPN服务器以使用生成的证书和密钥。 切换到OpenVPN配置目录: cd /etc/openvpn 复制并编辑服务器配置文件模板(例如server.conf.example)为server.conf: cp server.conf.example server.conf nano server.conf 在server.conf文件中,配置服务器的证书、密钥、端口、协议等参数。例如: port 1194 proto...
