[英]nginx as load balancer: upstream with path
我在端口9200上有一個nginx容器,它充當負載平衡器。 這是配置文件:
proxy_ignore_headers Set-Cookie;
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Headers' 'Range';
upstream backend {
server 192.168.99.103:9500 weight=3;
server 192.168.99.104:9500;
server 192.168.99.105:9500;
}
server {
listen 80;
server_name 172.17.0.1;
location = /LynyrdSkynyrdFreebirdAudio.mp4 {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Headers' 'Range';
if ($request_method = OPTIONS ) {
add_header Access-Control-Allow-Methods "GET, OPTIONS";
add_header Content-Length 0;
add_header Content-Type text/plain;
return 200;
}
proxy_pass http://backend/;
add_header X-Upstream $upstream_addr;
}
location = /LynyrdSkynyrdFreebirdVideo.mp4 {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Headers' 'Range';
if ($request_method = OPTIONS ) {
add_header Access-Control-Allow-Methods "GET, OPTIONS";
add_header Content-Length 0;
add_header Content-Type text/plain;
return 200;
}
proxy_pass http://backend;
add_header X-Upstream $upstream_addr;
}
}
此容器負載平衡以以下方式請求:到達請求localhost:9200/LynyrdSkynyrdFreebirdVideo.mp4
或localhost:9200/LynyrdSkynyrdFreebirdAudio.mp4
,它將在3個服務器之間平衡請求。 這3個服務器是3個充當緩存的nginx容器。 這是Nginx緩存的配置文件:
proxy_cache_path /tmp/nginx levels=1:2 keys_zone=my_zone:10m inactive=60m;
proxy_cache_key "$scheme$request_method$host$request_uri";
proxy_cache_methods GET HEAD POST;
proxy_cache_valid 200 206 100m;
proxy_ignore_headers Set-Cookie;
add_header 'Access-Control-Allow-Origin' '*' always;
add_header 'Access-Control-Allow-Headers' 'Range';
server {
listen 80;
server_name 172.17.0.1;
#charset koi8-r;

#
error_page 500 502 503 504 /50x.html;
location = /50x.html {

}

add_header X-Proxy-Cache $upstream_cache_status;

proxy_set_header Host $host;
proxy_pass http://192.168.99.103:9600/shaka-player/media/example-av1.mpd;
}
location = /LynyrdSkynyrdFreebirdVideo.mp4 {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Headers' 'Range';
proxy_cache my_zone;
add_header X-Proxy-Cache $upstream_cache_status;

proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
proxy_pass http://192.168.99.103:9600/shaka-player/media/LynyrdSkynyrdFreebirdVideo.mp4 ;

proxy_set_header Host $host;
proxy_pass http://192.168.99.103:9600/shaka-player/media/LynyrdSkynyrdFreebirdAudio.mp4;
}
}
如果我指向負載均衡器,即localhost:9200/LynyrdSkynyrdFreebirdVideo.mp4
或localhost:9200/LynyrdSkynyrdFreebirdAudio.mp4
,則找不到404
。 我希望,如果我指向此URL,負載均衡器192.168.99.103(or 104, or 105):9500/LynyrdSkynyrdFreebirdVideo.mp
請求平衡到192.168.99.103(or 104, or 105):9500/LynyrdSkynyrdFreebirdVideo.mp
4或192.168.99.103(or 104, or 105):9500/LynyrdSkynyrdFreebirdAudio.mp4
。 但是在upstream
塊中,我不知道是否可以在server
指令中添加路徑。
實際上,我認為這確實是個問題:實際上,如果我指向192.168.99.103 (or
104 , or
105 )
:9500 / LynyrdSkynyrdFreebirdAudio(或Video).mp4,則可以正確獲取內容。
誰能幫我?
解決了:
我已將路徑添加到http://backend
,例如:
proxy_pass http://backend/LynyrdSkynyrdFreebirdVideo.mp4;
