### Hot-Reload frpc configuration
|
||||
|

This feature is removed since v0.10.0.
|
||||
First you need to set admin port in frpc's configure file to let it provide HTTP API for more features.
|

```ini

# frpc.ini

||||
```
|
||||
|
||||
Then run command `frpc -c ./frpc.ini --reload` and wait for about 10 seconds to let frpc create or update or delete proxies.

||||

||||
### Get Real IP
|
||||
|
||||
Features for http proxy only.
|
||||
|
||||
You can get user's real IP from http request header `X-Forwarded-For` and `X-Real-IP`.
|
||||
|
||||
**Note that now you can only get these two headers in first request of each user connection.**
|
||||

||||
### Password protecting your web service
|
||||
|
||||
Anyone who can guess your tunnel URL can access your local web server unless you protect it with a password.

### 安全地暴露内网服务
|
||||
|
||||
对于某些服务来说如果直接暴露于公网上将会存在安全隐患。
|
||||
|
||||
使用 **stcp(secret tcp)** 类型的代理可以避免让任何人都能访问到要穿透的服务，但是访问者也需要运行另外一个 frpc。
|
||||
|
||||
以下示例将会创建一个只有自己能访问到的 ssh 服务代理。
|
||||
|
||||
frps 的部署步骤同上。
|
||||
|
||||
1. 启动 frpc，转发内网的 ssh 服务，配置如下，不需要指定远程端口：
|
||||
|
||||
```ini
|
||||
# frpc.ini
|
||||
[common]
|
||||
server_addr = x.x.x.x
|
||||
server_port = 7000
|
||||
|
||||
[secret_ssh]
|
||||
type = stcp
|
||||
# 只有 sk 一致的用户才能访问到此服务
|
||||
sk = abcdefg
|
||||
local_ip = 127.0.0.1
|
||||
local_port = 22
|
||||
```
|
||||
|
||||
2. 在要访问这个服务的机器上启动另外一个 frpc，配置如下：
|
||||
|
||||
```ini
|
||||
# frpc.ini
|
||||
[common]
|
||||
server_addr = x.x.x.x
|
||||
server_port = 7000
|
||||
|
||||
[secret_ssh_vistor]
|
||||
type = stcp
|
||||
# stcp 的访问者
|
||||
role = vistor
|
||||
# 要访问的 stcp 代理的名字
|
||||
server_name = secret_ssh
|
||||
sk = abcdefg
|
||||
# 绑定本地端口用于访问 ssh 服务
|
||||
bind_addr = 127.0.0.1
|
||||
bind_port = 6000

||||
```
|
||||

||||

|
||||
|
||||

||||

||||
### 通过 frpc 所在机器访问外网

||||
|
||||

||||

||||

|
||||
|
||||
如果传输的报文长度较长，通过设置 `use_compression = true` 对传输内容进行压缩，可以有效减小 frpc 与 frps 之间的网络流量，加快流量转发速度，但是会额外消耗一些 cpu 资源。
|
||||
|
||||
### 服务器端热加载配置文件
|
||||
### 客户端热加载配置文件
|
||||
|
||||
由于从 v0.10.0 版本开始，所有 proxy 都在客户端配置，这个功能暂时移除。
|
||||
当修改了 frpc 中的代理配置，可以通过 `frpc --reload` 命令来动态加载配置文件，通常会在 10 秒内完成代理的更新。
|
||||
|
||||
启用此功能需要在 frpc 中启用 admin 端口，用于提供 API 服务。配置如下：
|
||||
|
||||
```ini
|
||||
# frpc.ini
|
||||
[common]
|
||||
admin_addr = 127.0.0.1
|
||||
admin_port = 7400

||||
```
|
||||
|
||||
之后执行重启命令：
|
||||
|
||||
`frpc -c ./frpc.ini --reload`
|
||||
|
||||
等待一段时间后客户端会根据新的配置文件创建、更新、删除代理。

|

### 获取用户真实 IP
|
||||
|
||||
目前只有 **http** 类型的代理支持这一功能，可以通过用户请求的 header 中的 `X-Forwarded-For` 和 `X-Real-IP` 来获取用户真实 IP。
|
||||
|
||||
**需要注意的是，目前只在每一个用户连接的第一个 HTTP 请求中添加了这两个 header。**
|
||||
|
||||
### 通过密码保护你的 web 服务
|
||||
|
||||
由于所有客户端共用一个 frps 的 http 服务端口，任何知道你的域名和 url 的人都能访问到你部署在内网的 web 服务，但是在某些场景下需要确保只有限定的用户才能访问。
