本指南为您详细介绍了在CentOS 5系统上一键配置VPN的步骤,包括所需软件的安装、配置文件编辑、服务启动与测试,助您快速搭建稳定可靠的VPN连接。
准备工作
您需要以下准备工作:
1、一台运行CentOS 5的虚拟机或实体机;
2、配备公网IP地址的CentOS 5系统;
3、获取VPN服务器地址和端口(本文以OpenVPN为例);
4、适用于您操作系统的OpenVPN客户端软件。
OpenVPN服务器安装
我们将通过以下步骤在CentOS 5系统上安装OpenVPN服务器:
1、安装EPEL仓库:
```bash
sudo rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
```
2、安装OpenVPN:
```bash
sudo yum install openvpn easy-rsa -y
```
3、生成CA证书:
```bash
cd /etc/openvpn/easy-rsa/2.0/
source vars
./clean-all
./build-ca
```
4、生成服务器证书:
```bash
./build-key-server server
```
5、生成DH密钥:
```bash
./build-dh
```
6、生成服务器配置文件:
```bash
echo "port 1194" > /etc/openvpn/server.conf
echo "proto udp" >> /etc/openvpn/server.conf
echo "dev tun" >> /etc/openvpn/server.conf
echo "ca /etc/openvpn/easy-rsa/2.0/keys/ca.crt" >> /etc/openvpn/server.conf
echo "cert /etc/openvpn/easy-rsa/2.0/keys/server.crt" >> /etc/openvpn/server.conf
echo "key /etc/openvpn/easy-rsa/2.0/keys/server.key" >> /etc/openvpn/server.conf
echo "dh /etc/openvpn/easy-rsa/2.0/keys/dh2048.pem" >> /etc/openvpn/server.conf
echo "server 10.8.0.0 255.255.255.0" >> /etc/openvpn/server.conf
echo "ifconfig-pool-persist ipp.txt" >> /etc/openvpn/server.conf
echo "keepalive 10 120" >> /etc/openvpn/server.conf
echo "tls-auth /etc/openvpn/easy-rsa/2.0/keys/ta.key 0" >> /etc/openvpn/server.conf
echo "user nobody" >> /etc/openvpn/server.conf
echo "group nogroup" >> /etc/openvpn/server.conf
echo "status openvpn-status.log" >> /etc/openvpn/server.conf
echo "verb 3" >> /etc/openvpn/server.conf
echo "cipher AES-256-CBC" >> /etc/openvpn/server.conf
echo "script-security 3" >> /etc/openvpn/server.conf
echo "config-dir /etc/openvpn" >> /etc/openvpn/server.conf
```
7、生成客户端配置文件:
```bash
cd /etc/openvpn/easy-rsa/2.0/
source vars
./build-key client1
./build-key client2
```
8、生成客户端连接文件:
```bash
cd /etc/openvpn/easy-rsa/2.0/keys/
cat > client1.ovpn << EOF
client
dev tun
proto udp
remote <VPN服务器IP地址> <VPN服务器端口>
resolv-retry infinite
nobind
user nobody
group nogroup
persist-key
persist-tun
ca /etc/openvpn/easy-rsa/2.0/keys/ca.crt
cert client1.crt
key client1.key
tls-auth ta.key 0
cipher AES-256-CBC
comp-lzo
reneg-sec 3600
ns-cert-type server
EOF
同理,为其他客户端生成连接文件。
9、启动OpenVPN服务:
```bash
sudo systemctl start openvpn@server.service
sudo systemctl enable openvpn@server.service
```
客户端连接
1、下载并安装OpenVPN客户端软件;
2、将生成的客户端连接文件导入到OpenVPN客户端软件中;
3、启动OpenVPN客户端,输入密码(生成证书时设置的密码);
4、连接成功后,您的网络流量将通过VPN服务器加密传输。
通过以上步骤,您已经成功在CentOS 5系统上一键配置了VPN,使用VPN可以帮助您保护隐私、畅游海外资源,但请确保遵守当地法律法规,合理使用VPN。
