Can we use nginx for both wordpress and drupal?

You can run multiple sites using nginx, analogous to an apache vhost.

In /etc/nginx/sites-enabled, you can add two vhosts

wordpress.example.com

server {       listen 80;       server_name wordpress.example.com;       root /var/www/wordpress;#      if ($http_host != "www.example.com") {#                rewrite ^ http://www.example.com$request_uri permanent;#      }       index index.php index.html;       location = /favicon.ico {                log_not_found off;                access_log off;       }       location = /robots.txt {                allow all;                log_not_found off;                access_log off;       }       # Deny all attempts to access hidden files such as .htaccess, .htpasswd, .DS_Store (Mac).       location ~ /\. {                deny all;                access_log off;                log_not_found off;       }       location / {                try_files $uri $uri/ /index.php?$args;       }       # Add trailing slash to */wp-admin requests.       rewrite /wp-admin$ $scheme://$host$uri/ permanent;       location ~*  \.(jpg|jpeg|png|gif|css|js|ico)$ {                expires max;                log_not_found off;       }       location ~ \.php$ {                try_files $uri =404;                include /etc/nginx/fastcgi_params;                fastcgi_pass 127.0.0.1:9000;                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;       }}

and

drupal.example.com

server {       listen 80;       server_name drupal.example.com;       root /var/www/drupal;#      if ($http_host != "www.example.com") {#                rewrite ^ http://www.example.com$request_uri permanent;#      }       index index.php index.html;       location = /favicon.ico {                log_not_found off;                access_log off;       }       location = /robots.txt {                allow all;                log_not_found off;                access_log off;       }       # Deny all attempts to access hidden files such as .htaccess, .htpasswd, .DS_Store (Mac).       location ~ /\. {                deny all;                access_log off;                log_not_found off;       }       location / {                try_files $uri $uri/ /index.php?$args;       }       # Add trailing slash to */wp-admin requests.       rewrite /wp-admin$ $scheme://$host$uri/ permanent;       location ~*  \.(jpg|jpeg|png|gif|css|js|ico)$ {                expires max;                log_not_found off;       }       location ~ \.php$ {                try_files $uri =404;                include /etc/nginx/fastcgi_params;                fastcgi_pass 127.0.0.1:9001;                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;       }}
