[+] (Only for Linux) Improve web server performance with nginx 1.3. Administrators can improve the work of the web server which hosts customer websites by installing nginx, a supplementary high-performance web server specifically designed for delivering large amounts of static content. Plesk Panel 11 Linux introduces Nginx
The system will configure this server to work as a reverse proxy – nginx becomes a frontend web server that processes all incoming requests from site visitors. The requests are sent to Apache which, in turn, distinguishes requests for static and dynamic content. If a request is for a static file (like jpg, css, html, and so on), Apache passes the request through all registered handlers (applies .htaccess directory-level configuration, rewrites a URL, and so on) and returns to nginx a response which contains only a location of the requested file on the file system. nginx locates the file and sends it to the client. If the request is for a dynamic file (like a PHP script), Apache executes the file and sends the response to nginx, which delivers it to the client.
Such combination of two servers gives the following advantages:
The maximum number of concurrent connections to a website increases.
The consumption of server CPU and memory resources decreases.
Efficiency of serving visitors with slow connection speed (GPRS, EDGE, 3G, and so on) improves.
1. Create the file: /etc/nginx/conf.d/gzip.conf
Enter the following:
gzip on;
gzip_comp_level 9;
gzip_min_length 1400;
gzip_proxied any;
gzip_types text/plain text/css image/png image/gif image/jpeg application/x-javascript text/xml application/xml application/x
ml+rss text/javascript;
gzip_vary on;
gzip_disable "MSIE [1-6]\.(?!.*SV1)";
Then restart nginx in Plesk Services Management. Note that text/html doesn’t need to be specified with gzip_types (and in fact produces a configuration warning if you try). Once you set gzip on, nginx automatically assumes text/html as a gzip type.
