Tran­si­tion to nginx: part 4 – CGI scripts

I still have some CGI scripts on this web­site. They still work, and they are good enough for my needs. When I switched this web­site to nginx (the word­press set­up was a lit­tle bit more com­plex than what I wrote in part 1, part 2 and part 3… the con­fig will be one of my next blog posts) I was a lit­tle bit puz­zled how to do that with nginx. It took me some min­utes to get an idea how to do it and to find the right FreeB­SD port for this.

  • Install www/fcgiwrap
  • Add the fol­low­ing to rc.conf:

fcgiwrap_enable="YES"
fcgiwrap_user="www"

  • Run “ser­vice fcgi­wrap start”
  • Add the fol­low­ing to your nginx con­fig:
location ^~ /cgi-bin/ {
    gzip off; #gzip makes scripts feel slower since they have to complete before getting gzipped
    fastcgi_pass  unix:/var/run/fcgiwrap/fcgiwrap.sock;
    fastcgi_index index.cgi;
    fastcgi_param SCRIPT_FILENAME /path/to/location$fastcgi_script_name;
    fastcgi_param GATEWAY_INTERFACE  CGI/1.1;
}

Tran­si­tion to nginx: part 3 — short and easy con­fig snip­pets

After some medium-difficoulty tran­si­tions in part 1 and part 2, here some easy ones:

php­MyAd­min: take the basics from one of the two oth­er blog posts (see above) with­out loca­tion direc­tives. For “loca­tion /” set the doc­u­ment root and copy the “loca­tion ~ \.php” from the con­fig of one of the parts above. Done.

TT-RSS: take the con­fig like for php­MyAd­min and add (assum­ing it is in the root of the serv­er, else you have to add the path in the front of the loca­tion)

location ^~ /(utils|templates|schema|cache|lock|locale|classes) {
     deny all;
}

Allow client-side caching for sta­t­ic con­tent:

location ~* \.(?:jpe?g|gif|png|ico|cur|gz|bz2|xz|tbz|tgz|txz|svg|svgz|mp4|ogg|ogv|webm|htc|css|js|
pdf|zip|rar|tar|txt|conf)$ {
    try_files $uri =404;

    expires 1w;     # If you are not a big site,

                    # and don't change static content often,

                    # 1 week is not bad.
    access_log off; # If you don't need the logs
    add_header Cache-Control "public";
}

Secu­ri­ty: Despite the fact that the docs I’ve read tell that no-SSLv3 is the default, the first set­ting makes a dif­fer­ence (test­ed via SSLlabs’ SSLtest).

ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # No SSLv 2/3
ssl_dhparam /path/to/dhparams.pem;   # generate via "openssl dhparam -out /path/to/dhparams.pem 2048"
