Hi Mik,
I am no expert on nginx, just a user, and I have never had to split a
site as you are. That said, I think the error is that you have wrapped
your locations inside each other. This means that when it matches /, it
goes on to pass .php files to app1, without ever looking for /app2.
You need three location statements.
location / {
root /var/www/htdocs/app1
try_files to serve app1 static content
}
location /app2
root /var/www/htdocs/app2
try_files to serve app2 static content
}
location ~ \.php {
# no root needed here
fastcgi stuff here
}
The line within \.php that sets SCRIPT_FILENAME to
$document_root$fastcgi_script_name will
pass the different roots to php, so app1 and
app2 will each get the correct script names.
Regards
Ian
