前置条件：

公网服务器1台

可访问的域名一个

域名解析

假设你的域名是 test.com

将frp.test.com解析到你的公网服务器ip

将*.frp.test.com解析到frp.test.com

服务器下载frp

# 访问 GitHub 发布页下载最新版本# https://github.com/fatedier/frp/releases

# 下载示例（替换为最新版本）
wget https://github.com/fatedier/frp/releases/download/v0.52.3/frp_0.52.3_linux_amd64.tar.gz

# 解压
tar -zxvf frp_0.52.3_linux_amd64.tar.gz
cd frp_0.52.3_linux_amd64

创建/etc/frp/frps.ini

[common]
bind_port = 7000
dashboard_port = 7500
dashboard_user = user
dashboard_pwd = pwdxxxxx
token = tokenxxxxx
subdomain_host=*.frp.test.com

# http端口
vhost_http_port=9898

# 启用 HTTPS
vhost_https_port = 7443

# 特权模式配置
allow_ports = 10000-20000
max_pool_count = 1000

# 详细日志
log_file = /var/log/frps.log
log_level = info
log_max_days = 7

# TLS 配置
tls_only = false

创建systemd服务

创建/etc/systemd/system/frps.service

[Unit]
Description=Frp Server Service
After=network.target

[Service]
Type=simple
User=nobody
Restart=on-failure
RestartSec=5s
ExecStart=/usr/local/bin/frps -c /etc/frp/frps.ini
ExecReload=/usr/local/bin/frps reload -c /etc/frp/frps.ini

[Install]
WantedBy=multi-user.target

安装和启动服务

# 复制文件到系统目录
sudo cp frps /usr/local/bin/
sudo mkdir -p /etc/frp
sudo cp frps.ini /etc/frp/

# 设置权限
sudo chmod 755 /usr/local/bin/frps
sudo chmod 644 /etc/frp/frps.ini

# 启动服务
sudo systemctl daemon-reload
sudo systemctl enable frps
sudo systemctl start frps

# 检查状态
sudo systemctl status frps

客户端配置：

[common]
server_addr = frp.test.com
server_port = 7000
token = tokenxxxxx

[[web01]]
type = http
local_ip = 127.0.0.1
local_port = 9898
custom_domains = pay.frp.test.com

# 高级配置
use_encryption = true
use_compression = true

[[web02]]
type = http
local_ip = 127.0.0.1
local_port = 8889
custom_domains = web.frp.test.com

nginx反向代理

server {
    listen 80;
    server_name *.frp.test.com;
    
    location / {
        proxy_pass http://127.0.0.1:9898;  # 客户端服务端口 9898 是服务端配置文件配置的，注意端口放行
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}
