## What is frp?
|
|
|
|
|
|
frp is a fast reverse proxy to help you expose a local server behind a NAT or firewall to the Internet. As of now, it supports **TCP** and **UDP**, as well as **HTTP** and **HTTPS** protocols, where requests can be forwarded to internal services by domain name.
|
|
|
|
|
|
frp also has a P2P connect mode.

## Development Status
|
|
|
|
|
|
frp is under development. Try the latest release version in the `master` branch, or use the `dev` branch for the version in development.
|
|
|
|
|
|
**The protocol might change at a release and we don't promise backwards compatibility. Please check the release log when upgrading the client and the server.**
|
|
|
|
|
|
## Architecture
|
|
|
|
|
|
|
|
|
|
|
|
## Example Usage
|
|
|
|
|
|
Firstly, download the latest programs from [Release](https://github.com/fatedier/frp/releases) page according to your operating system and architecture.
|
|
|
|
|
|
Put `frps` and `frps.ini` onto your server A with public IP.
|
|
|
|
|
|
Put `frpc` and `frpc.ini` onto your server B in LAN (that can't be connected from public Internet).
|
|
|
|
|
|
### Access your computer in LAN by SSH
|
|
|
|
|
|
1. Modify `frps.ini` on server A:
|
|
|
|
|
|
```ini
|
|
|
# frps.ini
|
|
|
[common]
|
|
|
bind_port = 7000
|
|
|
```
|
|
|
|
|
|
2. Start `frps` on server A:
|
|
|
|
|
|
`./frps -c ./frps.ini`
|
|
|
|
|
|
3. On server B, modify `frpc.ini` to put in your `frps` server public IP as `server_addr` field:
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[common]
|
|
|
server_addr = x.x.x.x
|
|
|
server_port = 7000
|
|
|
|
|
|
[ssh]
|
|
|
type = tcp
|
|
|
local_ip = 127.0.0.1
|
|
|
local_port = 22
|
|
|
remote_port = 6000
|
|
|
```
|
|
|
|
|
|
4. Start `frpc` on server B:
|
|
|
|
|
|
`./frpc -c ./frpc.ini`
|
|
|
|
|
|
5. From another machine, SSH to server B like this (assuming that username is `test`):
|
|
|
|
|
|
`ssh -oPort=6000 test@x.x.x.x`
|
|
|
|
|
|
### Visit your web service in LAN by custom domains
|
|
|
|
|
|
Sometimes we want to expose a local web service behind a NAT network to others for testing with your own domain name and unfortunately we can't resolve a domain name to a local IP.
|
|
|
|
|
|
However, we can expose an HTTP(S) service using frp.
|
|
|
|
|
|
1. Modify `frps.ini`, set the vhost HTTP port to 8080:
|
|
|
|
|
|
```ini
|
|
|
# frps.ini
|
|
|
[common]
|
|
|
bind_port = 7000
|
|
|
vhost_http_port = 8080
|
|
|
```
|
|
|
|
|
|
2. Start `frps`:
|
|
|
|
|
|
`./frps -c ./frps.ini`
|
|
|
|
|
|
3. Modify `frpc.ini` and set `server_addr` to the IP address of the remote frps server. The `local_port` is the port of your web service:
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[common]
|
|
|
server_addr = x.x.x.x
|
|
|
server_port = 7000
|
|
|
|
|
|
[web]
|
|
|
type = http
|
|
|
local_port = 80
|
|
|
custom_domains = www.example.com
|
|
|
```
|
|
|
|
|
|
4. Start `frpc`:
|
|
|
|
|
|
`./frpc -c ./frpc.ini`
|
|
|
|
|
|
5. Resolve A record of `www.example.com` to the public IP of the remote frps server or CNAME record to your origin domain.
|
|
|
|
|
|
6. Now visit your local web service using url `http://www.example.com:8080`.
|
|
|
|
|
|
### Forward DNS query request
|
|
|
|
|
|
1. Modify `frps.ini`:
|
|
|
|
|
|
```ini
|
|
|
# frps.ini
|
|
|
[common]
|
|
|
bind_port = 7000
|
|
|
```
|
|
|
|
|
|
2. Start `frps`:
|
|
|
|
|
|
`./frps -c ./frps.ini`
|
|
|
|
|
|
3. Modify `frpc.ini` and set `server_addr` to the IP address of the remote frps server, forward DNS query request to Google Public DNS server `8.8.8.8:53`:
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[common]
|
|
|
server_addr = x.x.x.x
|
|
|
server_port = 7000
|
|
|
|
|
|
[dns]
|
|
|
type = udp
|
|
|
local_ip = 8.8.8.8
|
|
|
local_port = 53
|
|
|
remote_port = 6000
|
|
|
```
|
|
|
|
|
|
4. Start frpc:
|
|
|
|
|
|
`./frpc -c ./frpc.ini`
|
|
|
|
|
|
5. Test DNS resolution using `dig` command:
|
|
|
|
|
|
`dig @x.x.x.x -p 6000 www.google.com`
|
|
|
|
|
|
### Forward Unix domain socket
|
|
|
|
|
|
Expose a Unix domain socket (e.g. the Docker daemon socket) as TCP.
|
|
|
|
|
|
Configure `frps` same as above.
|
|
|
|
|
|
1. Start `frpc` with configuration:
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[common]
|
|
|
server_addr = x.x.x.x
|
|
|
server_port = 7000
|
|
|
|
|
|
[unix_domain_socket]
|
|
|
type = tcp
|
|
|
remote_port = 6000
|
|
|
plugin = unix_domain_socket
|
|
|
plugin_unix_path = /var/run/docker.sock
|
|
|
```
|
|
|
|
|
|
2. Test: Get Docker version using `curl`:
|
|
|
|
|
|
`curl http://x.x.x.x:6000/version`
|
|
|
|
|
|
### Expose a simple HTTP file server
|
|
|
|
|
|
Browser your files stored in the LAN, from public Internet.
|
|
|
|
|
|
Configure `frps` same as above.
|
|
|
|
|
|
1. Start `frpc` with configuration:
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[common]
|
|
|
server_addr = x.x.x.x
|
|
|
server_port = 7000
|
|
|
|
|
|
[test_static_file]
|
|
|
type = tcp
|
|
|
remote_port = 6000
|
|
|
plugin = static_file
|
|
|
plugin_local_path = /tmp/files
|
|
|
plugin_strip_prefix = static
|
|
|
plugin_http_user = abc
|
|
|
plugin_http_passwd = abc
|
|
|
```
|
|
|
|
|
|
2. Visit `http://x.x.x.x:6000/static/` from your browser and specify correct user and password to view files in `/tmp/files` on the `frpc` machine.
|
|
|
|
|
|
### Enable HTTPS for local HTTP service
|
|
|
|
|
|
1. Start `frpc` with configuration:
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[common]
|
|
|
server_addr = x.x.x.x
|
|
|
server_port = 7000
|
|
|
|
|
|
[test_https2http]
|
|
|
type = https
|
|
|
custom_domains = test.example.com
|
|
|
|
|
|
plugin = https2http
|
|
|
plugin_local_addr = 127.0.0.1:80
|
|
|
plugin_crt_path = ./server.crt
|
|
|
plugin_key_path = ./server.key
|
|
|
plugin_host_header_rewrite = 127.0.0.1
|
|
|
plugin_header_X-From-Where = frp
|
|
|
```
|
|
|
|
|
|
2. Visit `https://test.example.com`.
|
|
|
|
|
|
### Expose your service privately
|
|
|
|
|
|
Some services will be at risk if exposed directly to the public network. With **STCP** (secret TCP) mode, a preshared key is needed to access the service from another client.
|
|
|
|
|
|
Configure `frps` same as above.
|
|
|
|
|
|
1. Start `frpc` on machine B with the following config. This example is for exposing the SSH service (port 22), and note the `sk` field for the preshared key, and that the `remote_port` field is removed here:
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[common]
|
|
|
server_addr = x.x.x.x
|
|
|
server_port = 7000
|
|
|
|
|
|
[secret_ssh]
|
|
|
type = stcp
|
|
|
sk = abcdefg
|
|
|
local_ip = 127.0.0.1
|
|
|
local_port = 22
|
|
|
```
|
|
|
|
|
|
2. Start another `frpc` (typically on another machine C) with the following config to access the SSH service with a security key (`sk` field):
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[common]
|
|
|
server_addr = x.x.x.x
|
|
|
server_port = 7000
|
|
|
|
|
|
[secret_ssh_visitor]
|
|
|
type = stcp
|
|
|
role = visitor
|
|
|
server_name = secret_ssh
|
|
|
sk = abcdefg
|
|
|
bind_addr = 127.0.0.1
|
|
|
bind_port = 6000
|
|
|
```
|
|
|
|
|
|
3. On machine C, connect to SSH on machine B, using this command:
|
|
|
|
|
|
`ssh -oPort=6000 127.0.0.1`
|
|
|
|
|
|
### P2P Mode
|
|
|
|
|
|
**xtcp** is designed for transmitting large amounts of data directly between clients. A frps server is still needed, as P2P here only refers the actual data transmission.
|
|
|
|
|
|
Note it can't penetrate all types of NAT devices. You might want to fallback to **stcp** if **xtcp** doesn't work.
|
|
|
|
|
|
1. In `frps.ini` configure a UDP port for xtcp:
|
|
|
|
|
|
```ini
|
|
|
# frps.ini
|
|
|
bind_udp_port = 7001
|
|
|
```
|
|
|
|
|
|
2. Start `frpc` on machine B, expose the SSH port. Note that `remote_port` field is removed:
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[common]
|
|
|
server_addr = x.x.x.x
|
|
|
server_port = 7000
|
|
|
|
|
|
[p2p_ssh]
|
|
|
type = xtcp
|
|
|
sk = abcdefg
|
|
|
local_ip = 127.0.0.1
|
|
|
local_port = 22
|
|
|
```
|
|
|
|
|
|
3. Start another `frpc` (typically on another machine C) with the config to connect to SSH using P2P mode:
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[common]
|
|
|
server_addr = x.x.x.x
|
|
|
server_port = 7000
|
|
|
|
|
|
[p2p_ssh_visitor]
|
|
|
type = xtcp
|
|
|
role = visitor
|
|
|
server_name = p2p_ssh
|
|
|
sk = abcdefg
|
|
|
bind_addr = 127.0.0.1
|
|
|
bind_port = 6000
|
|
|
```
|
|
|
|
|
|
4. On machine C, connect to SSH on machine B, using this command:
|
|
|
|
|
|
`ssh -oPort=6000 127.0.0.1`
|
|
|
|
|
|
## Features
|
|
|
|
|
|
### Configuration Files
|
|
|
|
|
|
Read the full example configuration files to find out even more features not described here.
|
|
|
|
|
|
[Full configuration file for frps (Server)](./conf/frps_full.ini)
|
|
|
|
|
|
[Full configuration file for frpc (Client)](./conf/frpc_full.ini)
|
|
|
|
|
|
### Using Environment Variables
|
|
|
|
|
|
Environment variables can be referenced in the configuration file, using Go's standard format:
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[common]
|
|
|
server_addr = {{ .Envs.FRP_SERVER_ADDR }}
|
|
|
server_port = 7000
|
|
|
|
|
|
[ssh]
|
|
|
type = tcp
|
|
|
local_ip = 127.0.0.1
|
|
|
local_port = 22
|
|
|
remote_port = {{ .Envs.FRP_SSH_REMOTE_PORT }}
|
|
|
```
|
|
|
|
|
|
With the config above, variables can be passed into `frpc` program like this:
|
|
|
|
|
|
```
|
|
|
export FRP_SERVER_ADDR="x.x.x.x"
|
|
|
export FRP_SSH_REMOTE_PORT="6000"
|
|
|
./frpc -c ./frpc.ini
|
|
|
```
|
|
|
|
|
|
`frpc` will render configuration file template using OS environment variables. Remember to prefix your reference with `.Envs`.
|
|
|
|
|
|
### Dashboard
|
|
|
|
|
|
Check frp's status and proxies' statistics information by Dashboard.
|
|
|
|
|
|
Configure a port for dashboard to enable this feature:
|
|
|
|
|
|
```ini
|
|
|
[common]
|
|
|
dashboard_port = 7500
|
|
|
# dashboard's username and password are both optional，if not set, default is admin.
|
|
|
dashboard_user = admin
|
|
|
dashboard_pwd = admin
|
|
|
```
|
|
|
|
|
|
Then visit `http://[server_addr]:7500` to see the dashboard, with username and password both being `admin` by default.
|
|
|
|
|
|
|
|
|
|
|
|
### Admin UI
|
|
|
|
|
|
The Admin UI helps you check and manage frpc's configuration.
|
|
|
|
|
|
Configure an address for admin UI to enable this feature:
|
|
|
|
|
|
```ini
|
|
|
[common]
|
|
|
admin_addr = 127.0.0.1
|
|
|
admin_port = 7400
|
|
|
admin_user = admin
|
|
|
admin_pwd = admin
|
|
|
```
|
|
|
|
|
|
Then visit `http://127.0.0.1:7400` to see admin UI, with username and password both being `admin` by default.
|
|
|
|
|
|
### Authenticating the Client
|
|
|
|
|
|
Always use the same `token` in the `[common]` section in `frps.ini` and `frpc.ini`.
|
|
|
|
|
|
### Encryption and Compression
|
|
|
|
|
|
The features are off by default. You can turn on encryption and/or compression:
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[ssh]
|
|
|
type = tcp
|
|
|
local_port = 22
|
|
|
remote_port = 6000
|
|
|
use_encryption = true
|
|
|
use_compression = true
|
|
|
```
|
|
|
|
|
|
#### TLS
|
|
|
|
|
|
frp supports the TLS protocol between `frpc` and `frps` since v0.25.0.
|
|
|
|
|
|
Config `tls_enable = true` in the `[common]` section to `frpc.ini` to enable this feature.
|
|
|
|
|
|
For port multiplexing, frp sends a first byte `0x17` to dial a TLS connection.
|
|
|
|
|
|
### Hot-Reloading frpc configuration
|
|
|
|
|
|
The `admin_addr` and `admin_port` fields are required for enabling HTTP API:
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[common]
|
|
|
admin_addr = 127.0.0.1
|
|
|
admin_port = 7400
|
|
|
```
|
|
|
|
|
|
Then run command `frpc reload -c ./frpc.ini` and wait for about 10 seconds to let `frpc` create or update or delete proxies.
|
|
|
|
|
|
**Note that parameters in [common] section won't be modified except 'start'.**
|
|
|
|
|
|
### Get proxy status from client
|
|
|
|
|
|
Use `frpc status -c ./frpc.ini` to get status of all proxies. The `admin_addr` and `admin_port` fields are required for enabling HTTP API.
|
|
|
|
|
|
### Only allowing certain ports on the server
|
|
|
|
|
|
`allow_ports` in `frps.ini` is used to avoid abuse of ports:
|
|
|
|
|
|
```ini
|
|
|
# frps.ini
|
|
|
[common]
|
|
|
allow_ports = 2000-3000,3001,3003,4000-50000
|
|
|
```
|
|
|
|
|
|
`allow_ports` consists of specific ports or port ranges (lowest port number, dash `-`, highest port number), separated by comma `,`.
|
|
|
|
|
|
### Port Reuse
|
|
|
|
|
|
`vhost_http_port` and `vhost_https_port` in frps can use same port with `bind_port`. frps will detect the connection's protocol and handle it correspondingly.
|
|
|
|
|
|
We would like to try to allow multiple proxies bind a same remote port with different protocols in the future.
|
|
|
|
|
|
### Bandwidth Limit
|
|
|
|
|
|
#### For Each Proxy
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[ssh]
|
|
|
type = tcp
|
|
|
local_port = 22
|
|
|
remote_port = 6000
|
|
|
bandwidth_limit = 1MB
|
|
|
```
|
|
|
|
|
|
Set `bandwidth_limit` in each proxy's configure to enable this feature. Supported units are `MB` and `KB`.
|
|
|
|
|
|
### TCP Stream Multiplexing
|
|
|
|
|
|
frp supports tcp stream multiplexing since v0.10.0 like HTTP2 Multiplexing, in which case all logic connections to the same frpc are multiplexed into the same TCP connection.
|
|
|
|
|
|
You can disable this feature by modify `frps.ini` and `frpc.ini`:
|
|
|
|
|
|
```ini
|
|
|
# frps.ini and frpc.ini, must be same
|
|
|
[common]
|
|
|
tcp_mux = false
|
|
|
```
|
|
|
|
|
|
### Support KCP Protocol
|
|
|
|
|
|
KCP is a fast and reliable protocol that can achieve the transmission effect of a reduction of the average latency by 30% to 40% and reduction of the maximum delay by a factor of three, at the cost of 10% to 20% more bandwidth wasted than TCP.
|
|
|
|
|
|
KCP mode uses UDP as the underlying transport. Using KCP in frp:
|
|
|
|
|
|
1. Enable KCP in frps:
|
|
|
|
|
|
```ini
|
|
|
# frps.ini
|
|
|
[common]
|
|
|
bind_port = 7000
|
|
|
# Specify a UDP port for KCP.
|
|
|
kcp_bind_port = 7000
|
|
|
```
|
|
|
|
|
|
The `kcp_bind_port` number can be the same number as `bind_port`, since `bind_port` field specifies a TCP port.
|
|
|
|
|
|
2. Configure `frpc.ini` to use KCP to connect to frps:
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[common]
|
|
|
server_addr = x.x.x.x
|
|
|
# Same as the 'kcp_bind_port' in frps.ini
|
|
|
server_port = 7000
|
|
|
protocol = kcp
|
|
|
```
|
|
|
|
|
|
### Connection Pooling
|
|
|
|
|
|
By default, frps creates a new frpc connection to the backend service upon a user request. With connection pooling, frps keeps a certain number of pre-established connections, reducing the time needed to establish a connection.
|
|
|
|
|
|
This feature is suitable for a large number of short connections.
|
|
|
|
|
|
1. Configure the limit of pool count each proxy can use in `frps.ini`:
|
|
|
|
|
|
```ini
|
|
|
# frps.ini
|
|
|
[common]
|
|
|
max_pool_count = 5
|
|
|
```
|
|
|
|
|
|
2. Enable and specify the number of connection pool:
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[common]
|
|
|
pool_count = 1
|
|
|
```
|
|
|
|
|
|
### Load balancing
|
|
|
|
|
|
Load balancing is supported by `group`.
|
|
|
|
|
|
This feature is only available for types `tcp` and `http` now.
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[test1]
|
|
|
type = tcp
|
|
|
local_port = 8080
|
|
|
remote_port = 80
|
|
|
group = web
|
|
|
group_key = 123
|
|
|
|
|
|
[test2]
|
|
|
type = tcp
|
|
|
local_port = 8081
|
|
|
remote_port = 80
|
|
|
group = web
|
|
|
group_key = 123
|
|
|
```
|
|
|
|
|
|
`group_key` is used for authentication.
|
|
|
|
|
|
Connections to port 80 will be dispatched to proxies in the same group randomly.
|
|
|
|
|
|
For type `tcp`, `remote_port` in the same group should be the same.
|
|
|
|
|
|
For type `http`, `custom_domains`, `subdomain`, `locations` should be the same.
|
|
|
|
|
|
### Service Health Check
|
|
|
|
|
|
Health check feature can help you achieve high availability with load balancing.
|
|
|
|
|
|
Add `health_check_type = tcp` or `health_check_type = http` to enable health check.
|
|
|
|
|
|
With health check type **tcp**, the service port will be pinged (TCPing):
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[test1]
|
|
|
type = tcp
|
|
|
local_port = 22
|
|
|
remote_port = 6000
|
|
|
# Enable TCP health check
|
|
|
health_check_type = tcp
|
|
|
# TCPing timeout seconds
|
|
|
health_check_timeout_s = 3
|
|
|
# If health check failed 3 times in a row, the proxy will be removed from frps
|
|
|
health_check_max_failed = 3
|
|
|
# A health check every 10 seconds
|
|
|
health_check_interval_s = 10
|
|
|
```
|
|
|
|
|
|
With health check type **http**, an HTTP request will be sent to the service and an HTTP 2xx OK response is expected:
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[web]
|
|
|
type = http
|
|
|
local_ip = 127.0.0.1
|
|
|
local_port = 80
|
|
|
custom_domains = test.example.com
|
|
|
# Enable HTTP health check
|
|
|
health_check_type = http
|
|
|
# frpc will send a GET request to '/status'
|
|
|
# and expect an HTTP 2xx OK response
|
|
|
health_check_url = /status
|
|
|
health_check_timeout_s = 3
|
|
|
health_check_max_failed = 3
|
|
|
health_check_interval_s = 10
|
|
|
```
|
|
|
|
|
|
### Rewriting the HTTP Host Header
|
|
|
|
|
|
By default frp does not modify the tunneled HTTP requests at all as it's a byte-for-byte copy.
|
|
|
|
|
|
However, speaking of web servers and HTTP requests, your web server might rely on the `Host` HTTP header to determine the website to be accessed. frp can rewrite the `Host` header when forwarding the HTTP requests, with the `host_header_rewrite` field:
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[web]
|
|
|
type = http
|
|
|
local_port = 80
|
|
|
custom_domains = test.example.com
|
|
|
host_header_rewrite = dev.example.com
|
|
|
```
|
|
|
|
|
|
The HTTP request will have the the `Host` header rewritten to `Host: dev.example.com` when it reaches the actual web server, although the request from the browser probably has `Host: test.example.com`.
|
|
|
|
|
|
### Setting other HTTP Headers
|
|
|
|
|
|
Similar to `Host`, You can override other HTTP request headers with proxy type `http`.
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[web]
|
|
|
type = http
|
|
|
local_port = 80
|
|
|
custom_domains = test.example.com
|
|
|
host_header_rewrite = dev.example.com
|
|
|
header_X-From-Where = frp
|
|
|
```
|
|
|
|
|
|
Note that parameter(s) prefixed with `header_` will be added to HTTP request headers.
|
|
|
|
|
|
In this example, it will set header `X-From-Where: frp` in the HTTP request.
|
|
|
|
|
|
### Get Real IP
|
|
|
|
|
|
#### HTTP X-Forwarded-For
|
|
|
|
|
|
This feature is for http proxy only.
|
|
|
|
|
|
You can get user's real IP from HTTP request headers `X-Forwarded-For` and `X-Real-IP`.
|
|
|
|
|
|
#### Proxy Protocol
|
|
|
|
|
|
frp supports Proxy Protocol to send user's real IP to local services. It support all types except UDP.
|
|
|
|
|
|
Here is an example for https service:
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[web]
|
|
|
type = https
|
|
|
local_port = 443
|
|
|
custom_domains = test.example.com
|
|
|
|
|
|
# now v1 and v2 are supported
|
|
|
proxy_protocol_version = v2
|
|
|
```
|
|
|
|
|
|
You can enable Proxy Protocol support in nginx to expose user's real IP in HTTP header `X-Real-IP`, and then read `X-Real-IP` header in your web service for the real IP.
|
|
|
|
|
|
### Require HTTP Basic auth (password) for web services
|
|
|
|
|
|
Anyone who can guess your tunnel URL can access your local web server unless you protect it with a password.
|
|
|
|
|
|
This enforces HTTP Basic Auth on all requests with the username and password specified in frpc's configure file.
|
|
|
|
|
|
It can only be enabled when proxy type is http.
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[web]
|
|
|
type = http
|
|
|
local_port = 80
|
|
|
custom_domains = test.example.com
|
|
|
http_user = abc
|
|
|
http_pwd = abc
|
|
|
```
|
|
|
|
|
|
Visit `http://test.example.com` in the browser and now you are prompted to enter the username and password.
|
|
|
|
|
|
### Custom subdomain names
|
|
|
|
|
|
It is convenient to use `subdomain` configure for http and https types when many people share one frps server.
|
|
|
|
|
|
```ini
|
|
|
# frps.ini
|
|
|
subdomain_host = frps.com
|
|
|
```
|
|
|
|
|
|
Resolve `*.frps.com` to the frps server's IP. This is usually called a Wildcard DNS record.
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[web]
|
|
|
type = http
|
|
|
local_port = 80
|
|
|
subdomain = test
|
|
|
```
|
|
|
|
|
|
Now you can visit your web service on `test.frps.com`.
|
|
|
|
|
|
Note that if `subdomain_host` is not empty, `custom_domains` should not be the subdomain of `subdomain_host`.
|
|
|
|
|
|
### URL routing
|
|
|
|
|
|
frp supports forwarding HTTP requests to different backend web services by url routing.
|
|
|
|
|
|
`locations` specifies the prefix of URL used for routing. frps first searches for the most specific prefix location given by literal strings regardless of the listed order.
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[web01]
|
|
|
type = http
|
|
|
local_port = 80
|
|
|
custom_domains = web.example.com
|
|
|
locations = /
|
|
|
|
|
|
[web02]
|
|
|
type = http
|
|
|
local_port = 81
|
|
|
custom_domains = web.example.com
|
|
|
locations = /news,/about
|
|
|
```
|
|
|
|
|
|
HTTP requests with URL prefix `/news` or `/about` will be forwarded to **web02** and other requests to **web01**.
|
|
|
|
|
|
### Connecting to frps via HTTP PROXY
|
|
|
|
|
|
frpc can connect to frps using HTTP proxy if you set OS environment variable `HTTP_PROXY`, or if `http_proxy` is set in frpc.ini file.
|
|
|
|
|
|
It only works when protocol is tcp.
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[common]
|
|
|
server_addr = x.x.x.x
|
|
|
server_port = 7000
|
|
|
http_proxy = http://user:pwd@192.168.1.128:8080
|
|
|
```
|
|
|
|
|
|
### Range ports mapping
|
|
|
|
|
|
Proxy with names that start with `range:` will support mapping range ports.
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[range:test_tcp]
|
|
|
type = tcp
|
|
|
local_ip = 127.0.0.1
|
|
|
local_port = 6000-6006,6007
|
|
|
remote_port = 6000-6006,6007
|
|
|
```
|
|
|
|
|
|
frpc will generate 8 proxies like `test_tcp_0`, `test_tcp_1`, ..., `test_tcp_7`.
|
|
|
|
|
|
### Client Plugins
|
|
|
|
|
|
frpc only forwards requests to local TCP or UDP ports by default.
|
|
|
|
|
|
Plugins are used for providing rich features. There are built-in plugins such as `unix_domain_socket`, `http_proxy`, `socks5`, `static_file` and you can see [example usage](#example-usage).
|
|
|
|
|
|
Specify which plugin to use with the `plugin` parameter. Configuration parameters of plugin should be started with `plugin_`. `local_ip` and `local_port` are not used for plugin.
|
|
|
|
|
|
Using plugin **http_proxy**:
|
|
|
|
|
|
```ini
|
|
|
# frpc.ini
|
|
|
[http_proxy]
|
|
|
type = tcp
|
|
|
remote_port = 6000
|
|
|
plugin = http_proxy
|
|
|
plugin_http_user = abc
|
|
|
plugin_http_passwd = abc
|
|
|
```
|
|
|
|
|
|
`plugin_http_user` and `plugin_http_passwd` are configuration parameters used in `http_proxy` plugin.
|
|
|
|
|
|
