All of the commands used in this post will require root or sudo access.

Install Nginx

pkg install nginx

Configure Nginx

Open /usr/local/etc/nginx/nginx.conf and edit the existing uncommented server { ... } section.

server {
    listen       80;

    ## Where to serve files from
    root /usr/local/www/nginx;

    index index.php index.html index.htm;

    ## Optionally change this to match the domain you want to listen on ex: www.example.com
    server_name  localhost;

    ## Attempt to serve file and fallback to 404 on fail.
    location / {
        try_files $uri $uri/ =404;
    }

    ## Custom error pages
    error_page  404              /404.html;
    error_page  500 502 503 504  /50x.html;

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

        #fastcgi_busy_buffers_size 256k;
        #fastcgi_temp_file_write_size 256k;

    }
}

Install PHP 5.6

pkg install php56

Configure PHP 5.6

There are two sample php.ini files provided by default. A production and development version. Copy the one you would like to use to enable it.

cp /usr/local/etc/php.ini-production /usr/local/etc/php.ini

Make a small security adjustment to the php.ini. Find the commented line with:

; cgi.fix_pathinfo=1

Uncomment it and set it to 0

cgi.fix_pathinfo=0

Enable Services

Edit /etc/rc.conf and add:

nginx_enable="YES"
php_fpm_enable="YES"

Start Services

service php-fpm start

service nginx start

Create a Test page

Create an index.php under /usr/local/www/nginx with the content:

<?php
phpinfo();

Now point your browser to the ip or domain of your server and you will see all the settings for your PHP installation.
