[英]Nginx TCP stream routing based on source IP
I have configured nginx as a reverse proxy for a TCP (non-http) stream.我已将 nginx 配置为 TCP(非 http)流的反向代理。 I'd like to apply different routing for a particular source IP address - can this be done, and how?
我想为特定的源 IP 地址应用不同的路由 - 这可以完成吗,如何完成? I'm aware of recomendations for the http module using the if directive, but that doesn't seem to work for these streams.
我知道使用if指令对 http 模块的推荐,但这似乎不适用于这些流。
Existing configuration:现有配置:
stream {
server {
listen 8000;
proxy_pass staging;
}
}
upstream staging {
server 1.2.3.4:8000;
}
Desired configuration (not working):所需的配置(不工作):
stream {
server {
listen 8000;
proxy_pass staging1;
if ( $remote_addr ~* 4.5.6.7 ) {
proxy_pass staging2;
}
}
}
upstream staging1 {
server 1.2.3.4:8000;
}
upstream staging2 {
server 1.2.3.44:8000;
}
This gives error '24314#24314: "if" directive is not allowed here', since it doesn't apply for the stream module - is there any other functionality how I could achieve this result?这会产生错误“24314#24314:此处不允许使用“if”指令”,因为它不适用于流模块 - 是否还有其他功能可以实现此结果?
in case some people are still wondering you can achieve this using a map:如果有些人仍然想知道您可以使用地图来实现这一点:
stream {
upstream staging1 {
server 1.2.3.4:8000;
}
upstream staging2 {
server 1.2.3.44:8000;
}
map $remote_addr $backend_svr {
4.5.6.7 "staging2";
default "staging1";
}
server {
listen 8000;
proxy_pass $backend_svr;
}
}
