If you ever would like to run multiple WordPress installations on one NGINX server and sharing one domain name. Also you would like to have nice urls like /%catetgory%/%postnname%/ on both of them. You better do not do it in the root configuration block like this:

location / {
  try_files $uri $uri/ /index.php?$args /another-nestetd-wp/index.php?$args;
}

Of course this will work… but as a side effect posts from /another-nested-wp/ will be leaking into main blog RSS feed. Trust me 🙂 I’ve only found out about this thanks to JVM Bloggers and my colleagues asking me wether my site was hacked 😀

Some things one need to learn the hard way.

Nevertheless, proper NGNIX, configuration should be done for /another-nested-wp/ (not root node):

location /another-nested-wp/ {
  try_files $uri $uri/ /another-nested-wp/index.php?$args;
}

This way both blogs shouldn’t interfere with each other. And both can use nice urls 😉

One again many thanks to the community from JVM Bloggers for quick information about this (self)hack 😉
