1、说明

        Lighttpd 是一个德国人领导的开源Web服务器软件，其根本的目的是提供一个专门针对高性能网站，安全、快速、兼容性好并且灵活的web server环境。具有非常低的内存开销、cpu占用率低、效能好以及丰富的模块等特点。

        Lighttpd是众多OpenSource轻量级的web server中较为优秀的一个。支持FastCGI，CGI，Auth，输出压缩(output compress)，URL重写，Alias等重要功能。

        PHP（PHP: Hypertext Preprocessor）即“超文本预处理器”，是在服务器端执行的脚本语言，尤其适用于Web开发并可嵌入HTML中。

本系统已经安装好，仅做过程演示；

2、安装步骤

  sudo apt update
  sudo apt install lighttpd
  sudo apt-get install php7.2 php7.2-fpm php7.2-cgi

3、修改lighttpd配置文件

server.document-root     = "/home/sunny/www"
server.upload-dirs          = ( "/home/sunny/www/lighttpd/uploads" )
server.errorlog               = "/home/sunny/www/lighttpd/error.log"
server.port                     = 8080

root@ubuntu:/usr/bin# cd /etc/lighttpd/
root@ubuntu:/etc/lighttpd# ls
conf-available  conf-enabled  lighttpd.conf
root@ubuntu:/etc/lighttpd# cat lighttpd.conf 
server.modules = (
	"mod_access",
	"mod_alias",
	"mod_compress",
 	"mod_redirect",
)

server.document-root        = "/home/sunny/www"
server.upload-dirs          = ( "/home/sunny/www/lighttpd/uploads" )
server.errorlog             = "/home/sunny/www/lighttpd/error.log"
server.pid-file             = "/var/run/lighttpd.pid"
server.username             = "www-data"
server.groupname            = "www-data"
server.port                 = 8080

index-file.names            = ( "index.php", "index.html", "index.lighttpd.html" )
url.access-deny             = ( "~", ".inc" )
static-file.exclude-extensions = ( ".php", ".pl", ".fcgi" )

compress.cache-dir          = "/var/cache/lighttpd/compress/"
compress.filetype           = ( "application/javascript", "text/css", "text/html", "text/plain" )

# default listening port for IPv6 falls back to the IPv4 port
## Use ipv6 if available
#include_shell "/usr/share/lighttpd/use-ipv6.pl " + server.port
include_shell "/usr/share/lighttpd/create-mime.assign.pl"
include_shell "/usr/share/lighttpd/include-conf-enabled.pl"

4、启动lighttpd

sudo /etc/init.d/lighttpd start

sudo /etc/init.d/lighttpd start    // 启动
sudo /etc/init.d/lighttpd stop     // 停止
sudo /etc/init.d/lighttpd restart  // 重启，修改配置文件会后，需要执行后生效

查看服务情况：
ps aux | grep lighttpd
lsof -i :8080
netstat -nlpt|grep 8080

root@ubuntu:/etc/lighttpd# ps aux | grep lighttpd
www-data    858  0.0  0.2  57616  4900 ?        Ss   13:25   0:00 /usr/sbin/lighttpd -D -f /etc/lighttpd/lighttpd.conf
root       3988  0.0  0.0  14432  1040 pts/0    S+   13:53   0:00 grep --color=auto lighttpd

root@ubuntu:/etc/lighttpd# lsof -i :8080
COMMAND  PID     USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
lighttpd 858 www-data    4u  IPv4  46670      0t0  TCP *:http-alt (LISTEN)

root@ubuntu:/etc/lighttpd# netstat -nlpt|grep 8080
tcp        0      0 0.0.0.0:8080            0.0.0.0:*               LISTEN      858/lighttpd   

5、创建测试文件

/home/sunny/www/index.php

sunny@ubuntu:~/www$ pwd
/home/sunny/www

sunny@ubuntu:~/www$ mkdir lighttpd
sunny@ubuntu:~/www$ touch lighttpd/error.log

sunny@ubuntu:~/www$ chmod  777  lighttpd
sunny@ubuntu:~/www$ chmod  777  lighttpd/error.log

sunny@ubuntu:~/www$ tree ./
./
├── index.php
└── lighttpd
    ├── error.log
    └── uploads

2 directories, 2 files

sunny@ubuntu:~/www$ vi index.php
<!DOCTYPE html>
<html>
<body>

<h1>My first PHP page</h1>

<?php
echo "Hello World!";
echo phpinfo();
?>

</body>
</html>

6、访问WEB

方法1：curl http://192.168.0.143:8080/

sunny@ubuntu:~/www$ curl http://192.168.0.143:8080/
<!DOCTYPE html>
<html>
<body>

<h1>My first PHP page</h1>

Hello World!<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"><head>
<style type="text/css">
body {background-color: #fff; color: #222; font-family: sans-serif;}
pre {margin: 0; font-family: monospace;}
a:link {color: #009; text-decoration: none; background-color: #fff;}
a:hover {text-decoration: underline;}
table {border-collapse: collapse; border: 0; width: 934px; box-shadow: 1px 2px 3px #ccc;}
.center {text-align: center;}
.center table {margin: 1em auto; text-align: left;}
.center th {text-align: center !important;}
td, th {border: 1px solid #666; font-size: 75%; vertical-align: baseline; padding: 4px 5px;}
h1 {font-size: 150%;}
h2 {font-size: 125%;}
.p {text-align: left;}
.e {background-color: #ccf; width: 300px; font-weight: bold;}
.h {background-color: #99c; font-weight: bold;}
.v {background-color: #ddd; max-width: 300px; overflow-x: auto; word-wrap: break-word;}
.v i {color: #999;}
img {float: right; border: 0;}
hr {width: 934px; background-color: #ccc; border: 0; height: 1px;}
</style>
<title>phpinfo()</title><meta name="ROBOTS" content="NOINDEX,NOFOLLOW,NOARCHIVE" /></head>
<body><div class="center">
......

方法2，浏览器访问：

7、PHP FastCgi

示例中已经配置了PHP FastCgi，配置步骤如下：

1、放开如下配置项
sudo vi /etc/php/7.2/fpm/php.ini
cgi.fix_pathinfo=1

sudo vi /etc/lighttpd/conf-available/15-fastcgi-php.conf 
"socket" => "/var/run/lighttpd/php7.2.socket",

2、重启php fpm
systemctl restart php7.2-fpm.service 

3、查询php状态
sunny@ubuntu:/home$ ps aux | grep php
root      14974  0.3  0.8 290452 16744 ?        Ss   16:01   0:00 php-fpm: master process (/etc/php/7.2/fpm/php-fpm.conf)
www-data  14975  0.0  0.3 292748  7620 ?        S    16:01   0:00 php-fpm: pool www
www-data  14976  0.0  0.3 292748  7620 ?        S    16:01   0:00 php-fpm: pool www
sunny     14980  0.0  0.0  14432  1032 pts/0    S+   16:02   0:00 grep --color=auto php

4、使能php fastcgi
sunny@ubuntu:/home$ sudo lighttpd-enable-mod fastcgi fastcgi-php
Enabling fastcgi: ok
Met dependency: fastcgi
Enabling fastcgi-php: ok
already enabled
Run "service lighttpd force-reload" to enable changes

5、重启lighttpd
sudo /etc/init.d/lighttpd stop
sudo /etc/init.d/lighttpd start

6、便能看到第6步的效果
