Nginx name-based virtual hosting configurations

You need to create directory structure as follows to host more than two websites under same IP address:

a] /websites : Host each domain under this directory. You need to create dirs as follows:

1. /websites/examples.com/http - Html / php / wordpress / forums files for example.com goes here.
2. /websites/examples.com/logs - Log files for example.com goes here.
3. /websites/examples.com/stats - awstats stats files for example.com goes here.

b] /usr/local/etc/nginx/vhosts: Host each domains configuration under this directory.

Your sample setup

1. IP address: 202.54.1.2
2. HTTP Port: 80
3. Domain1 : theos.in hosted at /websites/theos.in/http
4. Domain2 : cyberciti.biz hosted at /websites/cyberciti.biz/http

Create necessary directories

Type the following commands:
# D=/websites
# NROOT=/usr/local/etc/nginx
# mkdir $D
# mkdir $NROOT/vhosts
# mkdir /var/log/nginx/
# chown root:www /var/log/nginx/

Create / update default cache all ngnix config file

Open /usr/local/etc/nginx/nginx.conf file, enter:
# vi /usr/local/etc/nginx/nginx.conf
Update it as follows:

user  www www;
worker_processes  1;
 
# main server error log
error_log	/var/log/nginx/error.log ;
pid	/var/run/nginx.pid;
 
events {
	worker_connections  1024;
}
 
# main server config
http {
	include       mime.types;
	default_type  application/octet-stream;
	log_format  main  '$remote_addr - $remote_user [$time_local] $request '
                      '"$status" $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
 
	sendfile        on;
	#tcp_nopush     on;
    	#keepalive_timeout  0;
	keepalive_timeout  65;
	gzip  on;
 
	# default server for ip 202.54.1.2
	server {
        	listen          202.54.1.2:80 default;
        	server_name     _;
        	access_log      /var/log/nginx/access.log main;
        	server_name_in_redirect  off;
        	location / {
            		index index.html;
            		root  /usr/local/www/nginx;
        	}
	}
 
    # virtual hosting
    include /usr/local/etc/nginx/vhosts/*;
}

Where,

• user www www; :: Setup user and group name for Nginx server.
• worker_processes 1; :: nginx has the ability to use more than one worker process for large systems such as SMP system with tons of ram.
• error_log /var/log/nginx/error.log ; :: Default error log file.
• pid /var/run/nginx.pid; :: Default PID file.
• include mime.types; :: Set Multipurpose Internet Mail Extensions (MIME) for www communication from mime.types files.
• default_type application/octet-stream; :: Set default header media type of the message content
• log_format main '$remote_addr - $remote_user [$time_local] $request '
  '"$status" $body_bytes_sent "$http_referer" '
  '"$http_user_agent" "$http_x_forwarded_for"'; :: Directive log_format describes the format of a log entry.
• sendfile on; :: Activate the usage of sendfile().
• tcp_nopush on; :: This directive permits or forbids the use of the socket options TCP_NOPUSH on FreeBSD or TCP_CORK on Linux. This option is only available when using sendfile.
• keepalive_timeout 65; :: Set keep alive timeout.
• gzip on; :: Turn on gzip
• listen 202.54.1.2:80 default; :: Listen to given IP:port.
• server_name _; :: Assigns the names of virtual server.
• access_log /var/log/nginx/access.log main; :: Set path to access file.
• index index.html; :: Set default index file.
• root /usr/local/www/nginx; :: Set default document root.
• include /usr/local/etc/nginx/vhosts/*; :: Process all vhosts config files.

Create theos.in - 1st vhost directories

Type the following commands:
# mkdir $D/theos.in/{http,logs,stats}
# chown -R theosftpuser:theosftpgroup $D/theos.in/
Replace, username:groupname and domain name as per your setup.

theos.in Nginx virtual host config file

Open /usr/local/etc/nginx/vhosts/theos.in.conf file, enter:
# vi $NROOT/vhosts/theos.in.conf
Append configuration as follows:

server {
	listen  80;
        server_name  theos.in www.theos.in;
 
        access_log  /websites/theos.in/logs/access.log  main;
 
        location / {
            root   /websites/theos.in/http;
            index  index.php index.html index.htm;
        }
 
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /usr/local/www/nginx-dist;
        }
 
       # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        location ~ \.php$ {
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  /websites/theos.in/http$fastcgi_script_name;
            include        fastcgi_params;
        }
 
        location ~ /\.ht {
            deny  all;
        }
}

Save and close the file.

Create cyberciti.biz - 2nd vhost directories

Type the following commands:
# mkdir $D/cyberciti.biz/{http,logs,stats}
# chown -R user:group $D/cyberciti.biz/

cyberciti.biz Nginx virtual host config file

# vi $NROOT/vhosts/cyberciti.biz.conf
Append configuration as follows:

server {
	listen  80;
        server_name  cyberciti.biz www.cyberciti.biz;
 
        access_log  /websites/cyberciti.biz/logs/access.log  main;
 
        location / {
            root   /websites/cyberciti.biz/http;
            index  index.php index.html index.htm;
        }
 
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /usr/local/www/nginx-dist;
        }
 
       # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        location ~ \.php$ {
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  /websites/cyberciti.biz/http$fastcgi_script_name;
            include        fastcgi_params;
        }
 
        location ~ /\.ht {
            deny  all;
        }
}

Save and close the file. Restart Nginx web server, enter:
# nginx -c /usr/local/etc/nginx/nginx.conf -t
# /usr/local/etc/rc.d/nginx restart
