nginx, php-fpm and tilde user directories

Question

I'm using nginx and php5-fpm on a Debian system.

I want my server to serve like so;

• ip/index.html serves the static html page (or files) at the nginx web root
• and likewise, ip/somefile.php (or index.php) serves PHP through php-fpm
• ip/~user/index.html serves the static html page (or files) in /home/user/public_html
• and likewise, ip/~user/somefile.php (or index.php) serves PHP through php-fpm

(where ip is either an IPv4 or IPv6 address).

Here is my configuration for nginx:

server {
        listen 80;
        listen [::]:80 default_server ipv6only=on;

        server_name _;
        root /usr/share/nginx/www;
        index index.php index.html index.htm;

        # Deny access to all dotfiles
        location ~ /\. {
                deny all;
        }

        location ~ \.php$ {
                include /etc/nginx/fastcgi_params;

                try_files $uri = 404; # Prevents exploit
                fastcgi_pass unix:/var/run/php5-fpm.sock;
                fastcgi_index index.php;
        }

        # Serve user directories
        location ~ ^/~(.+?)(/.*)?$ {
                alias /home/$1/public_html$2;
                autoindex on;
        }
}

And for php-fpm:

; Start a new pool named 'www'.
; the variable $pool can we used in any directive and will be replaced by the
; pool name ('www' here)
[www]

; Per pool prefix
; It only applies on the following directives:
; - 'slowlog'
; - 'listen' (unixsocket)
; - 'chroot'
; - 'chdir'
; - 'php_values'
; - 'php_admin_values'
; When not set, the global prefix (or /usr) applies instead.
; Note: This directive can also be relative to the global prefix.
; Default Value: none
;prefix = /path/to/pools/$pool

; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
;       will be used.
user = www-data
group = www-data

; The address on which to accept FastCGI requests.
; Valid syntaxes are:
;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific address on
;                            a specific port;
;   'port'                 - to listen on a TCP socket to all addresses on a
;                            specific port;
;   '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
listen = /var/run/php5-fpm.sock

; Set listen(2) backlog.
; Default Value: 128 (-1 on FreeBSD and OpenBSD)
;listen.backlog = 128

; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web server. Many
; BSD-derived systems allow connections regardless of permissions.
; Default Values: user and group are set as the running user
;                 mode is set to 0666
;listen.owner = www-data
;listen.group = www-data
;listen.mode = 0666

; List of ipv4 addresses of FastCGI clients which are allowed to connect.
; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
; must be separated by a comma. If this value is left blank, connections will be
; accepted from any ip address.
; Default Value: any
;listen.allowed_clients = 127.0.0.1

; ... and more that doesn't matter, just defaults

Both static files and PHP work in nginx web root (ip/blah.html or ip/blah.php), static files also work in user directories (ip/~user/blah.html) however PHP is giving 404 in user directories.

Can someone help me fix my config?

Edit: some ls -las incase it's a permission issue.

Answer 1

You'll need to add this rule before the initial php one:

    # Serve user directories php files
    location ~ ^/~(.+?)(/.*\.php)$ {
            alias /home/$1/public_html;
            autoindex on;
            include /etc/nginx/fastcgi_params;

            try_files $2 = 404; # Prevents exploit
            fastcgi_pass unix:/var/run/php5-fpm.sock;
            fastcgi_index index.php;
    }

This one matches all php files in the user directory, directing them through php-fpm. The php rule you have matches all these php files, but tries to find them in the wrong directory.
