create cache and tmp directories, run mkdir -p /var/www/cache/tmp
nginx proxy for OpenStreetMap tiles

Nginx server configuration:

 server {
 proxy_cache_path /var/www/cache levels=1:2 keys_zone=openstreetmap-backend-cache:8m max_size=500000m inactive=1000d;
 proxy_temp_path /var/www/cache/tmp;

 upstream openstreetmap_backend {
 server a.tile.openstreetmap.org;
 server b.tile.openstreetmap.org;
 server c.tile.openstreetmap.org;
 }

 server {
 listen 80;
 server_name tile.example.com;

 location / {
 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 proxy_set_header X_FORWARDED_PROTO http;
 proxy_set_header Host $http_host;
 proxy_cache openstreetmap-backend-cache;
