Me, but it works locally.
I think I know how you did that. I should probably lock that down.

Re: Textpattern CMS demo site
Well, this is a problem. Branches-as-subdirectories needs some work, Nginx throws errors as my current config doesn’t recognise /branch/articles and needing to resolve to /branch for the index.php. Ugh.
I’ll need to unpick this. Might take a while.

All works fine from here
Thanks, Yiannis!
Anyone interested in the fix? Here goes.
Typically I install Textpatterns in the root of a domain, and the Nginx magic that binds the index.php to the site is in two parts:
location / {
index index.html index.php;
limit_except GET HEAD POST {
deny all;
}
try_files $uri $uri/ /index.php$is_args$args;
}To translate as best I can: the location block tells Nginx that everything inside refers to URLs that hang off /, the index line looks for index.html first, then checks for index.php, the limit_except block denies any HTTP requests that aren’t GET, HEAD or POST, and the try_files line tells Nginx to first try the URI as provided, then try the same thing with a trailing slash if the raw URI fails, then try /index.php as the final fallback. In real terms, if I have actual directories in the Textpattern site (e.g. /banana/, /music/, /oleg-keep-out/) they will be used in preference to, say, a Textpattern section.
This all works A-OK if the Textpattern hangs off the domain root. However, when you get ideas above your station and think “Hey, I bet it would be neat to have GitHub branches as subdirectories”, you need to remember that THIS WILL NOT WORK and you need the following (example for dev branch):
location /dev/ {
try_files $uri $uri/ /dev/index.php$is_args$args;
}So…Nginx now has a /dev/ subdirectory block. It inherits the location directives from the first block above, so all that still works fine (index, try_files is all relevant to this new block), but crucially the index.php it refers to is not in the root. The correct index.php is in /dev/. This location block inherits all the higher-up directives from /, but uses its own try_files to replace the one it inherited.

location / {...
If you were thinking “But, Pete – that’s only one part of Nginx magic, what about the other part that includes a scary regex and some glue to make PHP-FPM work?”, then wonder no more! Look:
location ~ ^.+\.php(?:/.*)?$ {
fastcgi_hide_header "X-Powered-By";
fastcgi_keep_conn on;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_pass unix:/var/run/php/php-fpm74.sock;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
include fastcgi_params;
try_files $uri =404;
}This…took me a while to get right. It’s a location block to funnel any PHP requests through FastCGI and, given the right love and attention, is wicked-fast and seems secure. The fastcgi_pass line is the clever stuff that allows multiple versions of PHP on one server, and each site can use one of the installed versions. Local file socket (the .sock part) is faster than a localhost IP:port setup as there’s less overhead.
The main downside to PHP-FPM is…well, I’m still learning how to make PHP performant, and when things get very busy there are some occasions where PHP-FPM panics and stops. No errors in the log. Just…done.
And what is Pete’s actually-quite-clever-when-you-think-about-it solution? Well, dear reader, I’m glad you asked. I have set up PHP-FPM to run on the external IP addresses and localhost. So, you hit PHP-FPM when you access the Textpattern sites, and that works fine…and every n minutes I have a shell script run a curl task to check the HTTP headers of a PHP-FPM status on 127.0.0.1 (one port per version of PHP). If there’s a 200 OK status, nothing happens. If there’s anything else, it automatically restarts PHP-FPM, waits 5 seconds and tries again. 99% of the time it works seamlessly, but that 1% that it doesn’t, I get an alert email.

Re: Textpattern CMS demo site
That’s some cool tech there, Sir. I’ve never delved into PHP-FPM . I really should. But then I’ve not used Nginx in anger either. Just once, and that was pretty much default-leave-it-and-run-away. Note to self: learn more.
