Trouble with Nginx Rewrite Rules - php

Question

I'm fairly new to Nginx, and I'm working on converting an .htaccess file into something nginx can make sense of. Everything's working well (mostly) - I can pull up the homepage just fine. The problem is when I get to a post page.
think similar to wordpress, URLs like:
http://www.example.com/12/post-title-in-slug-form
Where 12 is the post id, and obviously that string is the post slug. I'm trying to parse those as two separate arguments (id & slug) and pass them into index.php like I was successfully doing in apache. I'm getting a 404 page, though, and have confirmed it is because of the rewriterule. Here's what the entire config file looks like, with only the website name changed (for privacy):
user www-data;
worker_processes 4;
pid /run/nginx.pid;
events {
worker_connections 768;
# multi_accept on;
}
http {
##
# Basic Settings
##
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
# server_tokens off;
# server_names_hash_bucket_size 64;
# server_name_in_redirect off;
include /etc/nginx/mime.types;
default_type application/octet-stream;
##
# Logging Settings
##
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
##
# Gzip Settings
##
gzip on;
gzip_disable "msie6";
# gzip_vary on;
# gzip_proxied any;
# gzip_comp_level 6;
# gzip_buffers 16 8k;
# gzip_http_version 1.1;
# gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;

server {

error_log on;
# deny access to .XYZ files
location ~ /\. {
return 403;
}
location ~ sitemap\.xml {
return 301 http://example.com/sitemap.php;
}
location ~ .php$ {
# Here you have to decide how to handle php
# Generic example configs below
# Uncomment and fix up one of the two options
# Option 1: Use FastCGI
fastcgi_index index.php;
include fastcgi_params;
fastcgi_pass unix:/var/run/php5-fpm.sock;
}
location / {
try_files $uri $uri/ #router;
}
location #router {
rewrite ^/([0-9]+)/?(.*)?/?$ /index.php?id=$1&slug=$2 last;
}
}
}
Please let me know if you can spot what's throwing it off when it comes to parsing the individual posts into ids and slugs and passing them. Thanks!

Answer 1

You should add a / in the beginning and a / before index.php like this :
rewrite ^/([0-9]+)/?(.*)?/?$ /index.php?id=$1&slug=$2 last;
Note i also used $1 and $2

Answer 2

If what you posted is indeed the COMPLETE config file, then the setup is missing something to handle PHP files as the regexp looks to be fine.
I actually think the config you posted cannot be the full one or that there is something fundamental going on as that config should have thrown errors and failed to load and also, since you mentioned that your PHP was loading fine, then it cannot be the posted config serving your website.
A better config is attached below:
FYI, try_files ABC XYZ last; is not valid syntax and you need at least two options in try_files. Anyway, fixed those in the posted config as well.
server {
listen 80;
server_name example.com;
access_log off;
error_log on;
# deny access to .XYZ files
location ~ /\. {
return 403;
}
location ~ sitemap\.xml {
return 301 http://example.com/sitemap.php;
}
location ~ .php$ {
# Here you have to decide how to handle php
# Generic example configs below
# Uncomment and fix up one of the two options
# Option 1: Use FastCGI
#fastcgi_index index.php;
#include fastcgi_params;
#fastcgi_pass unix:/var/run/php5-fpm.sock;
# Option 2: Pass to Apache
# Proxy_pass localhost:APACHE_PORT
}
location / {
try_files $uri $uri/ #router;
}
location #router {
rewrite ^/([0-9]+)/?(.*)/?$ /index.php?id=$1&slug=$2 last;
}
}
You will need to fix the PHP handling bit and choose which setup you want to implement.
I think though that you need to verify that you only have one instance of nginx running and that it is what is serving your site.
