在我的 nginx.conf 中有：

##
# PageSpeed

pagespeed on;
pagespeed FileCachePath /var/ngx_pagespeed_cache;
pagespeed Domain https://example.com;
pagespeed Domain *.example.com;
pagespeed MapOriginDomain "http://localhost" "https://example.com";


pagespeed LoadFromFile "https://example.com" "/usr/share/nginx/www/";
pagespeed LoadFromFileRuleMatch Disallow \.php$;

pagespeed XHeaderValue "Powered By ngx_pagespeed";
pagespeed ListOutstandingUrlsOnError on;
pagespeed EnableFilters extend_cache;

# image related
pagespeed EnableFilters rewrite_images;
pagespeed EnableFilters convert_gif_to_png;
pagespeed EnableFilters convert_jpeg_to_progressive;
pagespeed EnableFilters strip_image_color_profile;
pagespeed EnableFilters strip_image_meta_data;
pagespeed EnableFilters jpeg_subsampling;
pagespeed EnableFilters lazyload_images;

# code related
pagespeed EnableFilters collapse_whitespace;

# DNS …

这是我的service nginx status命令结果。(Debian 8 64 位)
