How to compile NGINX and support PHP

NGINX is a high-performance web server, as well as acting as a reverse proxy and load balancer. Compared with other servers, NGINX takes up less memory resources and keeps the system load low. It has always been favored by many people.

Although NGINX itself supports Serving static content, it does not have a built-in PHP interpreter and requires additional installation to support PHP.

This article will show you how to compile NGINX and support PHP.

Prerequisites

Before starting the installation, please make sure that the gcc, make and zlib-devel packages have been installed on your system. These packages can be installed with the following command:

$ sudo yum install gcc make zlib-devel

Download and Unzip

First, you need to download the NGINX source code. You can download the latest version from the official website.

$ wget https://nginx.org/download/nginx-1.19.2.tar.gz

Unzip the downloaded file:

$ tar -zxvf nginx-1.19.2.tar.gz

Enter the decompression directory:

$ cd nginx-1.19.2

Compile and install

To compile NGINX and support PHP, you need to compile Add --with-http_stub_status_module and --with-http_realip_module parameters when using NGINX.

The following are the compilation commands:

$ ./configure --prefix=/usr/local/nginx \
--with-http_stub_status_module \
--with-http_realip_module \
--with-http_ssl_module \
--add-module=/usr/local/src/ngx_cache_purge \
--add-module=/usr/local/src/headers-more-nginx-module \
--add-module=/usr/local/src/ngx_http_upstream_session_sticky_module \
--add-module=/usr/local/src/encrypted-session-nginx-module \
--add-module=/usr/local/src/nginx-module-vts

$ make && sudo make install

The above command will cause NGINX to be packaged with the real-time IP module and support SSL via the --with-http_ssl_module parameter. In addition, some third-party modules have been added, such as ngx_cache_purge, headers-more-nginx-module, ngx_http_upstream_session_sticky_module, encrypted-session-nginx-module and nginx-module-vts, etc.

PHP Support

To support PHP in NGINX, make sure FPM is enabled when installing PHP. FPM is the abbreviation of FastCGI Process Manager, which interconnects PHP and NGINX.

Next, add the following to NGINX’s configuration file to enable PHP support.

location ~ \.php$ {
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    include        fastcgi_params;
}

SCRIPT_FILENAMEThe parameter specifies the path to the PHP script.

Conclusion

Now you can use the high performance of NGINX with the addition of PHP, and the combination will make your web applications faster and more scalable.

In this process, you learned how to compile NGINX to support PHP. Adding PHP to NGINX can take your web application's performance to the next level.
