nginx try_files如果想多次判断的话下面的方式是不行的，比如：
try_files $uri @eva2480 @eva24;
这样写永远都是最后一个参数生效，可以使用下面的方式，下级判断。
server {
listen 81;
server_name xxx1;
access_log /usr/local/nginx/logs/access81.log access;
root /b;
error_page 405 =200 $uri;
location / {
try_files $uri @eva2480;
}
location @eva2480 {
proxy_redirect off ;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header REMOTE-HOST $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://xxx2;
}
}
server {
listen 80;
server_name xxx;
access_log /usr/local/nginx/logs/access.log access;
error_page 405 =200 $uri;
location / {
root /2b;
try_files $uri @evaone;
}
location @evaone {
proxy_redirect off ;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header REMOTE-HOST $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://xxx1:81;
}
