考虑到实现“轻量级”Web服务器的要求，本案例摈弃了传统了LAMP(linux + apache + mysql + php)以及LNMP(linux + nginx + mysql + php)构架，而采用了更为轻便的LNSP构架，即linux + nginx + sqlite + php
部署nginx服务器
1.运行sudo apt-get install nginx，安装nginx软件包。
2.运行sudo /etc/init.d/nginx start，启动nginx服务。
3.运行sudo vi /etc/nginx/sites-available/default，修改server中的代码如下：
server {
listen 80 default_server;
#listen [::]:80 default_server;
# SSL configuration
#
# listen 443 ssl default_server;
# listen [::]:443 ssl default_server;
#
# Note: You should disable gzip for SSL traffic.
# See: https://bugs.debian.org/773332
#
# Read up on ssl_ciphers to ensure a secure configuration.
# See: https://bugs.debian.org/765782
#
# Self signed certs generated by the ssl-cert package
# Don't use them in a production server!
#
# include snippets/snakeoil.conf;
root /var/www/html;
# Add index.php to the list if you are using PHP
index index.html index.htm index.nginx-debian.html index.php;
server_name _;
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ =404;
}
# pass PHP scripts to FastCGI server
#
location ~ \.php$ {
include snippets/fastcgi-php.conf;
#
# # With php-fpm (or other unix sockets):
fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
# # With php-cgi (or other tcp sockets):
# fastcgi_pass 127.0.0.1:9000;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
部署php和sqlite服务
1.运行sudo apt-get install php7.0-fpm php7.0-sqlite3，安装php和sqlite软件包。
2.运行sudo /etc/init.d/nginx reload，重新加载nginx的配置。
测试LNSP构架响应
1.浏览器内直接访问树莓派IP地址，见到如下画面，表示可以正常访问静态html页面。
2.运行sudo vi /var/www/html/index.php，新建测试用php文档。输入下列code：
<?php print <<< EOT <!doctype html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Test successful</title> </head> <body> <h1>Test successful</h1> <p>Congratulations.</p> <p>Your webserver and PHP are working.</p> </body> </html> EOT; ?>
3.浏览器内打开树莓派IP/index.php，见到下面状态则表示php文件可以正常运作。
下一节，将开始部署内网穿透，通过动态域名解析技术从外部访问网页。
