如何自动执行此nginx重写规则？

Question

I'm afraid I'm in way over my head. I'm sure I'm missing something simple, but it's not clicking together so far. Any help would be greatly appreciated.

I've got a domain that hosts a number of micro sites, structured like so:

• domain.com/site1
• domain.com/site2
• domain.com/site3
• ...

I'm converting over from Apache to Nginx. When I was using Apache, this is the set of rewrite rules that worked for as many folders as I wanted.

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond $1#%{REQUEST_URI} ([^#]*)#(.*)\1$
RewriteRule ^(.*)$ %2index.php [QSA,L]

At this point, I am able to get the sites working using individual rules. But it's not really a feasible solution for my circumstance.

location /site1 {
    try_files $uri $uri/ /site1/index.php?$args;
}
location /site2 {
    try_files $uri $uri/ /site2/index.php?$args;
}
location /site3 {
    try_files $uri $uri/ /site3/index.php?$args;
}

There's gotta be a better way. I'm just such a noobie with Nginx, I can't quite figure it out. Thanks in advance for your help.

Answer 1

After reading a reply on my first answer I've changed it to this, don't know if you'll need the $suburi but it's there just in case.

server {
  server_name example.com;
  index index.php; # need this
  location / {
    try_files $uri $uri/ /index.php;
  }
  location ^~ (?<subfolder>/[^/]+)(?<suburi>.+) {
    try_files $uri $uri/ $subfolder/index.php$is_args$query_string;
  }
}

Alternative with no named capture blocks

  location ^~ (/[^/]+)(.+) {
    try_files $uri $uri/ $1/index.php$is_args$query_string;
  }

Answer 2

I finally found a solution here: https://github.com/rtCamp/easyengine/issues/31

set $dir "";
if ($request_uri ~ ^/([^/]*)/.*$ ) {
  set $dir1 /$1;
}
location / {
  try_files $uri $uri/  $dir1/index.php?$args;
}

Answer 3

I think about something like these:

location ~ ^/(.*)/*.*$ {
    try_files $uri $uri/ /$1/index.php?$args;
}
