nginx大于1.15.2版本
stream {
upstream http {
server localhost:8000;
}
upstream https {
server localhost:8001;
}
map $ssl_preread_protocol $upstream {
default https;
"" http;
}
server {
listen 8080;
listen [::]:8080;
proxy_pass $upstream;
ssl_preread on;
}
}
server {
listen 8000;
listen [::]:8000;
listen 8001 ssl;
listen [::]:8001 ssl;
...
关键设置 ssl_preread on。有了这个设置之后，可以使用map指令，通过 $ssl_preread_protocol 判断不同的ssl协议进行分发
