Support #622
Updated by Daniel Curtis over 8 years ago
{{>toc}}
Here is a procedure to install a FreeBSD with Nginx, PostgreSQL and PHP server stack. If any version of the packages needs to be changed, replace the versions in the commands accordingly.
There are also extra additions for running Ruby web applications with Phusion Passenger, and Perl CGI web applications using FastCGI.
h1. Prepare the Environment
* Before installation of the components, make sure everything is up to date using the following command:
<pre>
pkg update -f && pkg upgrade
</pre>
* Install portmaster:
<pre>
cd /usr/ports/ports-mgmt/portmaster
make install clean
pkg2ng
</pre>
---
h1. Install Nginx
* Install Nginx
<pre>
portmaster www/nginx
</pre>
* Start and enable nginx at boot:
<pre>
echo 'nginx_enable="YES"' >> /etc/rc.conf
service nginx start
</pre>
* Create a configuration directory to make managing individual server blocks easier
<pre>
mkdir /usr/local/etc/nginx/conf.d
</pre>
* Edit the main nginx config file:
<pre>
vi /usr/local/etc/nginx/nginx.conf
</pre>
#* And strip down the config file and add the include statement at the end to make it easier to handle various server blocks:
<pre>
worker_processes 1;
error_log /var/log/nginx-error.log;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
# Load config files from the /etc/nginx/conf.d directory
include /usr/local/etc/nginx/conf.d/*.conf;
}
</pre>
h2. Default Static Website
Start by setting up a simple static website, no server-side stuff PHP or Ruby; just plain HTML, CSS, JavaScript, etc.
* Create a directory for the web site:
<pre>
mkdir /usr/local/www/www.example.com
</pre>
* Add a *default site server block*:
<pre>
vi /usr/local/etc/nginx/conf.d/www.example.com.conf
</pre>
#* Add the following:
<pre>
server {
listen 80 default_server;
server_name www.example.com;
access_log /var/log/www.example.com.log main;
location / {
root /usr/local/www/www.example.com;
index index.html index.htm;
}
# redirect server error pages to the static page /50x.html
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/local/www/nginx-dist;
}
}
</pre>
---
h1. Install PostgreSQL 9.4
* Install PostgreSQL:
<pre>
portmaster databases/postgresql94-server
</pre>
* Enable PostgreSQL at boot:
<pre>
echo 'postgresql_enable="YES"' >> /etc/rc.conf
</pre>
* Initialize the database:
<pre>
service postgresql initdb
</pre>
* Start PostgreSQL:
<pre>
service postgresql start
</pre>
* Edit the postgres config file:
<pre>
vi /usr/local/pgsql/data/postgresql.conf
</pre>
#* And modify the following:
<pre>
listen_addresses = '*'
</pre>
* Edit the pg_hba config file:
<pre>
vi /usr/local/etc/pgsql/data/pg_hba.conf
</pre>
#* And modify the following:
<pre>
# TYPE DATABASE USER CIDR-ADDRESS METHOD only
# Local connections
local all all trust
# IPv4 local connections:
host all all 127.0.0.1/32 trust
# IPv6 local connections:
host all all ::1/128 trust
# IPv4 connections:
host all all 192.168.10.0/24 md5
# IPv6 local connections:
host all all 1234::abcd/64 md5
</pre>
* And wrap up by restarting the nginx and postgresql servers:
<pre>
service nginx restart
service postgresql restart
</pre>
h2. Create a new user and database
* Switch to the pgsql user:
<pre>
su pgsql
</pre>
#* Create the somepgdb database:
<pre>
createdb somepgdb
</pre>
#* Then create the somepguser user:
<pre>
createuser -P
</pre>
#* Grant all privileges to somepgdb to somepguser:
<pre>
psql template1
GRANT ALL PRIVILEGES ON DATABASE "somepgdb" to somepguser;
\q
</pre>
* Exit from the pgsql user
<pre>
exit
</pre>
---
h1. Install PHP
The PHP support in FreeBSD is extremely modular so the base install is very limited. It is very easy to add support using the _lang/php5-extensions_ port. This port provides a menu driven interface to PHP extension installation. Alternatively, individual extensions can be installed using the appropriate port.
* Install PHP 5.6 and other supporting packages:
<pre>
portmaster lang/php56
</pre>
* Install PHP extensions and a few modules:
<pre>
portmaster lang/php56-extensions databases/php56-pgsql databases/php56-pdo_pgsql www/php56-session
</pre>
#* *NOTE*: There are many more PHP modules, to search for more PHP modules run:
<pre>
find /usr/ports/ -name "php56-*"
</pre>
#* *NOTE*: PHP capabilities can be further extended by using PECL packages, to search for more PECL packages run:
<pre>
find /usr/ports/ -name "pecl-*"
</pre>
* Configure the default PHP settings
<pre>
cp /usr/local/etc/php.ini-production /usr/local/etc/php.ini
</pre>
h2. Configure PHP-FPM
* Edit @/usr/local/etc/php-fpm.conf@:
<pre>
vi /usr/local/etc/php-fpm.conf
</pre>
#* Make the following changes:
<pre>
listen = /var/run/php-fpm.sock
listen.owner = www
listen.group = www
listen.mode = 0660
</pre>
* Start and enable PHP-FPM at boot:
<pre>
echo 'php_fpm_enable="YES"' >> /etc/rc.conf
service php-fpm start
</pre>
* Restart nginx:
<pre>
service nginx restart
</pre>
h2. PHP Website
* Create a directory for the web application:
<pre>
mkdir /usr/local/www/phpapp.example.com
</pre>
* Add a *phpapp.example.com server block*:
<pre>
vi /usr/local/etc/nginx/conf.d/phpapp.example.com.conf
</pre>
#* Add the following:
<pre>
server {
listen 80;
server_name phpapp.example.com;
root /usr/local/www/phpapp.example.com;
access_log /var/log/phpapp.example.com-access.log;
error_log /var/log/phpapp.example.com-error.log;
location / {
index index.php index.html index.htm;
}
# For all PHP requests, pass them on to PHP-FPM via FastCGI
location ~ \.php$ {
fastcgi_pass unix:/var/run/php-fpm.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; /usr/local/www/phpapp.example.com$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_script_name;
include fastcgi_params; # include extra FCGI params
}
}
</pre>

h1. (Extra) Install Phusion Passenger
* Install Passenger
<pre>
portmaster www/rubygem-passenger
</pre>
#* *NOTE*: Make sure to enable *@[X]NGINX@* while configuring rubygem-passenger
#* *NOTE*: Enabling *[X]SYMLINK* makes upgrading passenger easier later on.
#* *NOTE*: Ruby capabilities can be further extended by using rubygem packages, to search for more packages run:
<pre>
find /usr/ports/ -name "rubygem-*"
</pre>
* Reinstall nginx with passenger support:
<pre>
cd /usr/ports/www/nginx
make config
portmaster www/nginx
</pre>
#* *NOTE*: Make sure to enable *@[X]PASSENGER@* while configuring _nginx_
h2. Configure Passenger
* Edit the main nginx config file:
<pre>
vi /usr/local/etc/nginx/nginx.conf
</pre>
#* And add the Passenger config parameters:
<pre>
#user nobody;
worker_processes 1;
error_log /var/log/nginx-error.log;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
# Load Phusion Passenger module globally
passenger_root /usr/local/lib/ruby/gems/2.1/gems/passenger;
passenger_ruby /usr/local/bin/ruby21;
passenger_max_pool_size 15;
passenger_pool_idle_time 300;
# Load config files from the /etc/nginx/conf.d directory
include /usr/local/etc/nginx/conf.d/*.conf;
}
</pre>
* Restart nginx to load passenger:
<pre>
service nginx restart
</pre>
h2. Ruby Website
* Create a directory for the web application:
<pre>
mkdir /usr/local/www/rubyapp.example.com
</pre>
* Add a *rubyapp.example.com server block*:
<pre>
vi /usr/local/etc/nginx/conf.d/rubyapp.example.com.conf
</pre>
#* Add the following:
<pre>
server {
listen 80;
server_name rubyapp.example.com;
root /usr/local/www/rubyapp.example.com/public;
access_log /var/log/rubyapp.example.com-access.log;
error_log /var/log/rubyapp.example.com-error.log;
passenger_enabled on;
passenger_user www;
passenger_group www;
}
</pre>
* Restart nginx to load the website config:
<pre>
service nginx restart
</pre>
---
h1. (Extra) Install FastCGI
I occasionally need to run a perl CGI script, FastCGI is capable of handling this task.
* Install fcgiwrap
<pre>
pkg install fcgiwrap p5-FCGI
</pre>
* Start and enable uwsgi at boot:
<pre>
echo 'fcgiwrap_enable="YES"' >> /etc/rc.conf
echo 'fcgiwrap_profiles="main"' >> /etc/rc.conf
echo 'fcgiwrap_main_socket="unix:/tmp/fcgiwrap.sock"' >> /etc/rc.conf
echo 'fcgiwrap_main_user="www"' >> /etc/rc.conf
service fcgiwrap start
</pre>
h2. CGI Website
* Create a directory for the web application:
<pre>
mkdir /usr/local/www/cgi-app.example.com
</pre>
* Add a *cgi-app.example.com server block*:
<pre>
vi /usr/local/etc/nginx/conf.d/cgi-app.example.com.conf
</pre>
#* Add the following:
<pre>
upstream fcgiwrap {
server unix:/tmp/fcgiwrap.sock;
}
server {
listen 80;
server_name cgi-app.example.com;
root /usr/local/www/cgi-app.example.com;
access_log /var/log/cgi-app.example.com-access.log;
error_log /var/log/cgi-app.example.com-error.log;
location / {
try_files $uri $uri/ =404;
}
location ~ \.cgi$ {
include /usr/local/etc/nginx/fastcgi_params;
fastcgi_index index.cgi;
fastcgi_pass fcgiwrap;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}
</pre>
* Restart nginx to load the website config:
<pre>
service nginx restart
</pre>

h1. Securing Nginx With SSL
* Install OpenSSL:
<pre>
pkg install openssl
</pre>
Enabling SSL in Nginx is simple. First add the ssl directive in the server listen option, then add the SSL certificate and key paths.
* The basic SSL server block should be look similar to the following:
<pre>
server {
listen 443 ssl;
server_name www.example.com;
ssl_certificate www.example.com.crt;
ssl_certificate_key www.example.com.key;
}
</pre>
* Setup the Diffie-Hellman Key Exchange Parameters
<pre>
cd /usr/local/etc/nginx
openssl dhparam -out dhparam.pem 4096
</pre>
* Generate a strong SSL key and a CSR to send for signing by a CA:
<pre>
cd /usr/local/etc/nginx
openssl req -sha512 -out www.example.com.csr -new -newkey rsa:4096 -nodes -keyout www.example.com.key
</pre>
#* If the received SSL certificate requires additional bundle certificates, like a CA intermediate bundle, add them together like so:
<pre>
cd /usr/local/etc/nginx
cat www.example.com.crt startcom.class1.bundle > www.example.com.chained.crt
</pre>
* Setup the default site configuration:
<pre>
vi /usr/local/etc/nginx/conf.d/www.example.com.conf
</pre>
#* Then add or modify the configuration to look similar to the following:
<pre>
server {
listen 80;
listen 443 default ssl;
server_name www.example.com;
# Turn on ans set SSL key/cert
ssl on;
ssl_certificate /usr/local/etc/nginx/www.example.com.crt;
ssl_certificate_key /usr/local/etc/nginx/www.example.com.key;
# Strong SSL configuration
ssl_ciphers 'AES128+EECDH:AES128+EDH:!aNULL';
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_session_cache builtin:1000 shared:SSL:10m;
ssl_stapling on;
ssl_stapling_verify on;
ssl_prefer_server_ciphers on;
ssl_dhparam /usr/local/etc/nginx/dhparam.pem;
add_header Strict-Transport-Security max-age=63072000;
add_header X-Frame-Options SAMEORIGIN;
add_header X-Content-Type-Options nosniff;
root /usr/local/www/;
index index.html index.htm;
autoindex on;
}
</pre>
* Restart nginx to load the new website config:
<pre>
service nginx restart
</pre>
