以下是在Debian 11上安装和配置OpenVPN的步骤:
1. 更新软件包列表:
```
sudo apt update
```
2. 安装OpenVPN软件包和EasyRSA工具:
```
sudo apt install openvpn easy-rsa
```
3. 创建OpenVPN的配置目录:
```
sudo mkdir /etc/openvpn/server
```
4. 复制OpenVPN的示例配置文件:
```
sudo cp /usr/share/doc/openvpn/examples/sample-config-files/server.conf.gz /etc/openvpn/server/
```
5. 解压缩配置文件:
```
sudo gzip -d /etc/openvpn/server/server.conf.gz
```
6. 生成证书和密钥:
```
cd /usr/share/easy-rsa/
sudo ./easyrsa init-pki
sudo ./easyrsa build-ca
sudo ./easyrsa build-server-full server nopass
```
7. 复制证书和密钥到OpenVPN的配置目录:
```
sudo cp /usr/share/easy-rsa/pki/ca.crt /etc/openvpn/server/
sudo cp /usr/share/easy-rsa/pki/issued/server.crt /etc/openvpn/server/
sudo cp /usr/share/easy-rsa/pki/private/server.key /etc/openvpn/server/
```
8. 生成Diffie-Hellman参数:
```
sudo openssl dhparam -out /etc/openvpn/server/dh.pem 2048
```
9. 配置OpenVPN服务器:
编辑OpenVPN配置文件:
```
sudo nano /etc/openvpn/server/server.conf
```
确保以下配置项与下面的示例配置文件相同:
```
port 1194
proto udp
dev tun
ca /etc/openvpn/server/ca.crt
cert /etc/openvpn/server/server.crt
key /etc/openvpn/server/server.key
dh /etc/openvpn/server/dh.pem
server 10.8.0.0 255.255.255.0
ifconfig-pool-persist ipp.txt
push "redirect-gateway def1 bypass-dhcp"
push "dhcp-option DNS 8.8.8.8"
push "dhcp-option DNS 8.8.4.4"
keepalive 10 120
cipher AES-256-CBC
user nobody
group nogroup
persist-key
persist-tun
status openvpn-status.log
verb 3
```
10. 启动OpenVPN服务:
```
sudo systemctl start openvpn-server@server
```
11. 确认服务已经启动:
```
sudo systemctl status openvpn-server@server
```
12. 配置防火墙:
如果您的服务器上有防火墙,请允许OpenVPN的UDP端口(默认为1194)通过防火墙。
完成以上步骤后,您的OpenVPN服务器就已经搭建完成了。您可以使用OpenVPN客户端连接到该服务器,以便安全地访问您的服务器或局域网中的资源。
