nginx realip 是一个nginx模块,主要用于解决在反向代理中获取客户端真实IP的问题。
在使用nginx反向代理时,客户端的请求会先到达nginx服务器,然后nginx服务器再将请求转发给后端的上游服务器。在这个转发过程中,原始的客户端IP会被替换成nginx服务器的IP,这导致后端服务器无法获取到真实的客户端IP,而只能获取到nginx服务器的IP。
为了解决这个问题,nginx提供了realip模块。通过配置该模块,nginx可以将原始客户端IP恢复到后端服务器的HTTP头中,使得后端服务器能够获取到客户端的真实IP。
使用realip模块的方法比较简单,只需在nginx的配置文件中添加几行配置即可。首先要设置real_ip_header指令,用于指定保存原始IP的HTTP头名称,常用的值是"X-Real-IP"和"X-Forwarded-For"。然后还要设置real_ip_recursive指令为on,以便nginx能够从逗号分隔的HTTP头中获取到真实IP。
配置好后,nginx在接收到客户端请求时,会从指定的HTTP头中读取原始IP,并将其保存到内部变量$realip_remote_addr中。我们可以通过在日志文件或后端服务器上打印该变量,来验证实际获取到的真实IP。
总之,通过使用nginx的realip模块,可以解决反向代理中获取客户端真实IP的问题,方便后端服务器做一些IP相关的处理,如限制访问、日志记录等。

nginx stream_realip_module
The nginx stream_realip_module is a module that allows nginx to obtain the real IP address of a client by replacing the client's IP address with the one specified in the X-Forwarded-For or X-Real-IP header. This is useful in situations where nginx is behind a load balancer or proxy server, as the original client IP address may be lost in the process.
When the stream_realip_module is enabled, nginx replaces the client's IP address with the IP address specified in the X-Forwarded-For or X-Real-IP header. This allows the actual client IP address to be logged and used for access control, rate limiting, or other purposes.
To use the stream_realip_module, the following steps are required:
1. Install nginx with the stream_realip_module enabled.
2. Add the following configuration to the nginx.conf file:
```
stream {
real_ip_header X-Forwarded-For;
real_ip_recursive on;
...
}
```
In this example, the real IP address is obtained from the X-Forwarded-For header and the `real_ip_recursive` option is enabled to allow multiple X-Forwarded-For headers to be processed.
3. Restart nginx.
Once the stream_realip_module is configured, nginx will obtain the real IP address of the client and use it in place of the proxy or load balancer IP address. This can help ensure that access control and other security measures are applied correctly.
nginx 真实ip
nginx获取用户的真实IP地址的方法是通过设置real_ip模块来实现的。在nginx的配置文件中,可以使用set_real_ip_from指令来指定允许的代理服务器IP地址,然后使用real_ip_header指令来指定真实IP地址的请求头。例如,可以在nginx的配置文件中添加以下内容来获取真实IP地址:
```
set_real_ip_from 192.168.50.0/24;
set_real_ip_from 61.22.22.22;
set_real_ip_from 121.207.33.33;
set_real_ip_from 127.0.0.1;
real_ip_header X-Forwarded-For;
real_ip_recursive on;
```
其中,set_real_ip_from指令用于指定允许的代理服务器IP地址,real_ip_header指令用于指定真实IP地址的请求头。在这个例子中,X-Forwarded-For请求头被用作真实IP地址的来源。\[2\]
通过设置这些配置后,nginx就能够正确获取用户的真实IP地址,并将其传递给后端的服务器。这对于负载均衡和日志记录非常有用。\[1\]
