简介

Lighttpd是一个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。

安装与简单配置

lighttpd安装与配置

1. 首先安装epel源，如果已经安装，忽略。

   wget http://epel.mirror.net.in/epel/6/i386/epel-release-6-8.noarch.rpm
   rpm -ivh epel-release-6-8.noarch.rpm
   

2. yum安装lighttpd

   yum install lighttpd lighttpd-fastcgi
   

3. 配置和简单的测试

   1. vim /etc/lighttpd/lighttpd.conf
   
   2. 找到server.use-ipv6 = "enable"，将"enbale"改为"disable"
   
   3. /etc/init.d/lighttpd start
   
   4. 执行 "wget -q -O - http://localhost" 观察访问是否正常
   

PHP安装与配置

1. 安装php

   yum install php-cli
   

2. 配置php与lighttpd

   1. vim /etc/php.ini
      找到cgi.fix_pathinfo，将其值置为1，结果为："cgi.fix_pathinfo=1"
   
   2. vim /etc/lighttpd/modules.conf
      找到include "conf.d/fastcgi.conf"，将其前面的注释删除。
   
   3. vim /etc/lighttpd/conf.d/fastcgi.conf
      找到php的配置，做如下更改，主要更改了socket和bin-path两个参数的值
   
      fastcgi.server = ( ".php" =>
              ( "php-local" =>
                (
                  "socket" => "/tmp/php-fastcgi-1.socket",
                  "bin-path" => "/usr/bin/php-cgi",
                  "max-procs" => 1,
                  "broken-scriptfilename" => "enable",
                )
              ),
              ( "php-tcp" =>
                (
                  "host" => "127.0.0.1",
                  "port" => 9999,
                  "check-local" => "disable",
                  "broken-scriptfilename" => "enable",
                )
              ),
          ( "php-num-procs" =>
            (
              "socket" => "/tmp/php-fastcgi-2.socket",
              "bin-path" => "/usr/bin/php-cgi",
              "bin-environment" => (
                "PHP_FCGI_CHILDREN" => "16",
                "PHP_FCGI_MAX_REQUESTS" => "10000",
              ),
              "max-procs" => 5,
              "broken-scriptfilename" => "enable",
            )
          ),
       )
   4. 创建文件/var/www/lighttpd/index.php，写入如下内容
       <?php phpinfo(); ?>
   5. 重启lighttpd, 然后访问http://localhost/index.php，查看输出是否正确
   

MySQL安装和配置

1. 安装MySQL和php的MySQL依赖

   yum install php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc
   

2. 重启lighttpd以后，访问http://localhost/index.php，查看是否已经有MySQL支持。

总结

到这里，一个简单的Light+PHP+MySQL开发环境就搭建完成了。
