请按照说明进行upstream conf 的配置；

upstream testserver_v5 {
server 10.18.210.76:81 weight=1;
upsync 10.18.210.83:2379/v2/keys/namespace/upstreams/test_server_v5/ upsync_timeout=5m upsync_interval=1000ms upsync_type=etcd strong_dependency=off;
upsync_dump_path /usr/local/fountain/3rdparty/nginx/conf/servers/test_server_v5.conf;
}

=>

upstream testserver_v5 {
upsync 10.18.210.83:2379/v2/keys/namespace/upstreams/test_server_v5/ upsync_timeout=5m upsync_interval=1000ms upsync_type=etcd strong_dependency=off;
upsync_dump_path /usr/local/fountain/3rdparty/nginx/conf/servers/test_server_v5.conf;
include /usr/local/fountain/3rdparty/nginx/conf/servers/test_server_v5.conf;
}
