It is similar to installing other software. The installation process is basically fool-proof
Install nginx, execute the following command, and it will be completed quickly
sudo apt-get install nginx
Default installation location of configuration file:
conf: /etc/nginx/nginx.conf
bin:/usr/sbin/nginx
vhost: /etc/nginx /sites-enable/default
cgi-params: /etc/nginx/fastcgi-params
Install php-cgi module
sudo apt-get install php5 -cgi
Default installation location of the configuration file:
php-cgi: /usr/bin/php-cgi
php5-cgi: /usr/bin/php5-cgi
cgi config: /usr/bin/cgi/php.ini
One thing to note here is that the cgi.fix_pathinfo data in the php.ini file must be modified to 1, the default is 0 cgi.fix_pathinfo=1; In this way, php-cgi can use the script_filename variable normally.
Install spawn-fcgi
If the system does not have the gcc compilation environment installed, you just need to install the build-essential tool package before installing lighttpd, execute the following command:
sudo apt-get install build-essential
wget http://www.lighttpd.net/download/lighttpd-1.4.19.tar.gz
tar -xvf lighttpd-1.4.19.tar .gz
cd lighttpd-1.4.19/
sudo apt-get install libpcre3-dev
./configure –without-zlib –without-bzip2
make
sudo cp src/spawn- fcgi /usr/local/bin/spawn-fcgi
Start fast_cgi:
spawn-fcgi -a 127.0.0.1 -p 9000 -c 5 -u www- data -g www-data -f /usr/bin/php-cgi
Start nginx
sudo /etc/init.d/nginx start

The purpose of NGINXUnit is to simplify the deployment and management of web applications. Its advantages include: 1) Supports multiple programming languages, such as Python, PHP, Go, Java and Node.js; 2) Provides dynamic configuration and automatic reloading functions; 3) manages application lifecycle through a unified API; 4) Adopt an asynchronous I/O model to support high concurrency and load balancing.

NGINX started in 2002 and was developed by IgorSysoev to solve the C10k problem. 1.NGINX is a high-performance web server, an event-driven asynchronous architecture, suitable for high concurrency. 2. Provide advanced functions such as reverse proxy, load balancing and caching to improve system performance and reliability. 3. Optimization techniques include adjusting the number of worker processes, enabling Gzip compression, using HTTP/2 and security configuration.

The main architecture difference between NGINX and Apache is that NGINX adopts event-driven, asynchronous non-blocking model, while Apache uses process or thread model. 1) NGINX efficiently handles high-concurrent connections through event loops and I/O multiplexing mechanisms, suitable for static content and reverse proxy. 2) Apache adopts a multi-process or multi-threaded model, which is highly stable but has high resource consumption, and is suitable for scenarios where rich module expansion is required.

NGINX is suitable for handling high concurrent and static content, while Apache is suitable for complex configurations and dynamic content. 1. NGINX efficiently handles concurrent connections, suitable for high-traffic scenarios, but requires additional configuration when processing dynamic content. 2. Apache provides rich modules and flexible configurations, which are suitable for complex needs, but have poor high concurrency performance.

NGINX and Apache each have their own advantages and disadvantages, and the choice should be based on specific needs. 1.NGINX is suitable for high concurrency scenarios because of its asynchronous non-blocking architecture. 2. Apache is suitable for low-concurrency scenarios that require complex configurations, because of its modular design.

NGINXUnit is an open source application server that supports multiple programming languages and provides functions such as dynamic configuration, zero downtime updates and built-in load balancing. 1. Dynamic configuration: You can modify the configuration without restarting. 2. Multilingual support: compatible with Python, Go, Java, PHP, etc. 3. Zero downtime update: Supports application updates that do not interrupt services. 4. Built-in load balancing: Requests can be distributed to multiple application instances.

NGINXUnit is better than ApacheTomcat, Gunicorn and Node.js built-in HTTP servers, suitable for multilingual projects and dynamic configuration requirements. 1) Supports multiple programming languages, 2) Provides dynamic configuration reloading, 3) Built-in load balancing function, suitable for projects that require high scalability and reliability.

NGINXUnit improves application performance and manageability with its modular architecture and dynamic reconfiguration capabilities. 1) Modular design includes master processes, routers and application processes, supporting efficient management and expansion. 2) Dynamic reconfiguration allows seamless update of configuration at runtime, suitable for CI/CD environments. 3) Multilingual support is implemented through dynamic loading of language runtime, improving development flexibility. 4) High performance is achieved through event-driven models and asynchronous I/O, and remains efficient even under high concurrency. 5) Security is improved by isolating application processes and reducing the mutual influence between applications.
