PHP on nginx with fastcgi-caching

May 12, 2013


I have a little VPS that hosts my blog and other various small projects. With a recent nginx update, my configuration files stopped working and I had to cut fastcgi-caching from my setup. I spent about 2 hours searching for this, so I am putting it up here - in case anyone has uses for it. This setup uses php5-fpm and nginx.


Include this from the nginx.conf (include /etc/nginx/cache.conf).

fastcgi_cache_path /var/lib/nginx/cache levels=1:2 keys_zone=DEFAULT:10m inactive=5m; fastcgi_cache_key "$scheme$request_method$host$request_uri";
map $request_method $no_cache {
    default 0;
    POST 1;
    #no caching on post
map $http_cookie $no_cache {
    default 0;
    ~SESS 1;
    # PHP Session cookie


Include this from site configuration (for example: /etc/nginx/sites-enabled/

location ~ \.php {
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    # A handy function that became available in 0.7.31 that breaks down
    # The path information based on the provided regex expression
    # This is handy for requests such as file.php/some/paths/here/ fastcgi_param PATH_INFO
    fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
    fastcgi_param QUERY_STRING $query_string;
    fastcgi_param REQUEST_METHOD $request_method;
    fastcgi_param CONTENT_TYPE $content_type;
    fastcgi_param CONTENT_LENGTH $content_length;
    fastcgi_param SCRIPT_NAME $fastcgi_script_name;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_param REQUEST_URI $request_uri;
    fastcgi_param DOCUMENT_URI $document_uri;
    fastcgi_param DOCUMENT_ROOT $document_root;
    fastcgi_param SERVER_PROTOCOL $server_protocol;
    fastcgi_param GATEWAY_INTERFACE CGI/1.1;
    fastcgi_param SERVER_SOFTWARE nginx;
    fastcgi_param REMOTE_ADDR $remote_addr;
    fastcgi_param REMOTE_PORT $remote_port;
    fastcgi_param SERVER_ADDR $server_addr;
    fastcgi_param SERVER_PORT $server_port;
    fastcgi_param SERVER_NAME $server_name;
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_index index.php;
    fastcgi_cache DEFAULT;
    fastcgi_cache_valid 200 302 1h;
    fastcgi_cache_valid 301 1d;
    fastcgi_cache_valid 404 1m;
    fastcgi_cache_valid any 1m;
    fastcgi_cache_min_uses 1;
    fastcgi_cache_use_stale error timeout invalid_header http_500;
    fastcgi_cache_bypass $no_cache;
    fastcgi_no_cache $no_cache;
    fastcgi_ignore_headers Cache-Control Expires;
