### Load balancing
|
||||
|
||||
Load balancing is supported by `group`.
|
||||
This feature is available only for type `tcp` 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.
|
||||
|
||||
Proxies in same group will accept connections from port 80 randomly.
|
||||
|
||||
### Rewriting the Host Header
|
||||
|
||||
When forwarding to a local port, frp does not modify the tunneled HTTP requests at all, they are copied to your server byte-for-byte as they are received. Some application servers use the Host header for determining which development site to display. For this reason, frp can rewrite your requests with a modified host header. Use the `host_header_rewrite` switch to rewrite incoming HTTP requests.

### 负载均衡
|
||||
|
||||
可以将多个相同类型的 proxy 加入到同一个 group 中,从而实现负载均衡的功能。
|
||||
目前只支持 tcp 类型的 proxy。
|
||||
|
||||
```ini
|
||||
# fprc.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
|
||||
```
|
||||
|
||||
用户连接 frps 服务器的 80 端口,frps 会将接收到的用户连接随机分发给其中一个存活的 proxy。这样可以在一台 frpc 机器挂掉后仍然有其他节点能够提供服务。
|
||||
|
||||
要求 `group_key` 相同,做权限验证,且 `remote_port` 相同。
|
||||
|
||||
### 修改 Host Header
|
||||
|
||||
通常情况下 frp 不会修改转发的任何数据。但有一些后端服务会根据 http 请求 header 中的 host 字段来展现不同的网站,例如 nginx 的虚拟主机服务,启用 host-header 的修改功能可以动态修改 http 请求中的 host 字段。该功能仅限于 http 类型的代理。
