LAMP（linux+apache+mysql/mariadb+php)是当前流行的web框架，具有通用、跨平台、高性能、低价格的 优势。
一、php
1、简介
PHP是通用服务器端脚本编程语言，其主要用于web开发以实现动态web页面，它也是最早实现将脚本嵌入HTML源码文档中的服务器端脚本语言之一。
2、PHP Zend Engine
Zend Engine是开源的、PHP脚本语言的解释器。它的出现将PHP代码的处理过程分成了两个阶段：首先是分析PHP代码并将其转换为称作Zend opcode的二进制格式(类似Java的字节码)，并将其存储于内存中；第二阶段是使用Zend Engine去执行这些转换后的Opcode。
3、PHP的Opcode
Opcode是一种PHP脚本编译后的中间语言。PHP执行PHP脚本代码一般会经过如下4个步骤：
①Scanning(Lexing) —— 将PHP代码转换为语言片段(Tokens)
②Parsing —— 将Tokens转换成简单而有意义的表达式
③Compilation —— 将表达式编译成Opocdes
④Execution —— 顺次执行Opcodes，每次一条，从而实现PHP脚本的功能
4、php的加速器
基于PHP的特殊扩展机制如opcode缓存扩展也可以将opcode缓存于php的共享内存中，从而可以让同一段代码的后续重复执行时跳过编译阶段以提高性能。
常见的php加速器有：APC、eAccelerator、XCache、Zend Optimizer和Zend Guard Loader、NuSphere PhpExpress
5、php的安装
rpm包
编译安装
6、开源php站点程序：
wordpress
drupal, joomlar
phpwind(阿里)
discuz（腾讯）
二、简单搭建LAMP平台
1、apache和php结合的方式：
①php作为httpd的模块
②httpd基于CGI协议与php通信
③php工作为一个服务器，httpd与php基于fastcgi协议进行通信
2、php连接mysql：php (php-mysql) --> mysql protocol --> mysqld
3、示例：以自建独立博客站点（wordpress）为例演示LAMP环境的构建
httpd和mysql的安装配置这里不作详解，详见博客http://9124573.blog.51cto.com/9114573/1727201和http://9124573.blog.51cto.com/9114573/1731896
注：这里的httpd、php、mysql都安装于同一节点实为演示方便，实际环境中为分摊压力多分布于不同节点

root@node2 ~]# service httpd restart

[ OK ]
三、编译LAMP
1、编译安装httpd 2.4和二进制格式安装mariadb-5.5.36 （略）
2、编译安装php
㈠将php编译成httpd的模块
将 PHP 编译成 httpd 的模块时，需要指定使用 apxs2 来将其编译成 httpd 的模块。
①安装之前，需先安装好开发包组，并安装 libxml2-devel，bzip2-devel 和 libmcrypt-devel
yum -y groupinstall "Server Platform Development" "Development Tools"
yum -y install bzip2-devel libmcrypt-devel libxml2-devel
②下载源码包并安装
wget http://php.net/get/php-5.4.41.tar.bz2/from/a/mirror
tar xf php-5.4.41.tar.bz2
cd php-5.4.41
./configure --prefix=/usr/local/php --with-mysql=/usr/local/mysql --with-openssl --with-mysqli=/usr/local/mysql/bin/mysql_config --enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --enable-sockets --with-apxs2=/usr/local/apache/bin/apxs --with-mcrypt --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-bz2 --enable-maintainer-zts
make && make install
说明：
◇freetype是字体处理工具，zlib是压缩库，xml是扩展标记语言，mcrypt是加密库（要支持此加密功能，必须先安装好libmcrypt-devel）
◇若mysql服务端程序是以rpm方式安装的，则--with-mysql和--with-mysqli后不用指明具体位置
◇这里为了支持apahce的worker或event这两个MPM，编译时使用了--enable-maintainer-zts选项
◇若使用php5.3以上版本，为了链接Mysql数据库，可指定mysqlnd，这样在本机就不需先安装mysql或mysql开发包(mysql-devel)了，从php5.4开始就默认绑定mysqlnd了。如果已安装mysql-devel，可直接--with-mysql
--with-mysql=mysqlnd --with-pdo=mysqlnd --with-mysqli=mysqlnd
③为php提供配置文件
cp php.ini-production /etc/php.d/php.ini
④编辑httpd配置文件，以支持php文件，在/etc/httpd24/httpd.conf中输入：
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
⑤修改DirectoryIndex
DirectoryIndex index.php index.html
⑥测试php是否能够正常工作，在数据库中添加一个用户用于测试
MariaDB [(none)]> GRANT ALL ON *.* TO phpuser@localhost IDENTIFIED BY 'phppasswd';
MariaDB [(none)]> FLUSH PRIVILEGES;
⑦在服务器建立一个测试页面index.php
<?php
$link = mysql_connect('localhost','phpuser','phppasswd');
if ($link)
echo "success";
else
echo "fail";
mysql_close();
?>
⑧重启httpd服务并访问该页面
[root@node2 ~]# yum -y install bzip2-devel libmcrypt-devel
...
Installed:
bzip2-devel.x86_64 0:1.0.5-7.el6_0 libmcrypt-devel.x86_64 0:2.5.8-9.el6
Dependency Installed:

★安装xchache,为php加速
①下载并安装
wget http://xcache.lighttpd.net/pub/Releases/3.2.0/xcache-3.2.0.tar.bz2
tar zxvf xcache-3.2.0.tar.gz
cd xcache-3.2.0
/usr/local/php/bin/phpize #用phpize生成configure配置文件
./configure --enable-xcache [--enable-xcache-coverager --enable-xcache-optimizer] --with-php-config=/usr/local/php/bin/php-config # 通过with-php-config指定将其编译为php的模块
make && make install
安装完成后，会出现下面一行：
/usr/local/php/lib/php/extensions/no-debug-zts-20100525/ #xcache.so所在目录
②提供配置文件
cp xcache.ini /etc/php.d/
cd /etc/php.d
vim /etc/php.d/xcache.ini

㈡将php编译成php-fpm（此时php工作为一个服务器，php与httpd基于fastcgi协议进行通信)
①编译安装
tar xf php-5.4.41.tar.bz2
cd php-5.4.41
./configure --prefix=/usr/local/php5 --with-mysql=/usr/local/mysql --with-openssl --with-mysqli=/usr/local/mysql/bin/mysql_config --enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --enable-sockets --enable-fpm --with-mcrypt --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-bz2
make && make install
②为php提供配置文件
cp php.ini-production /etc/php.ini
③为php-fpm提供服务启动脚本，并将其添加至chkconfig控制
cp sapi/fpm/init.d.php-fpm /etc/rc.d/init.d/php-fpm
chmod +x /etc/rc.d/init.d/php-fpm
chkconfig --add php-fpm
chkconfig php-fpm on
④为php-fpm提供配置文件
cp /usr/local/php5/etc/php-fpm.conf.default /usr/local/php5/etc/php-fpm.conf
⑤编辑php-fpm配置文件
vim /usr/local/php5/etc/php-fpm.conf
配置fmp的相关选项为需要的值，并启用pid文件
pm.max_child = 25
pm.start_servers = 5
pm.min_spare_servers = 2
pm.max_spare_servers = 6
pid = /usr/local/php5/var/run/php-fpm.pid
⑥启动php-fpm
service php-fpm start (centos 7上为systemctl start php-fpm.service)
php-fpm默认监听在127.0.0.1的9000端口
配置httpd
⑦在httpd 2.4以后已经专门有一个模块针对FastCGI的实现，此模块为mod_proxy_fcgi.so，它其实是作为mod_proxy.so模块的扩充，因此，这两个模块都要加载
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so
⑧编辑httpd配置文件，让apache能够识别php格式的页面，并支持php格式的主页
vim /etc/httpd24/httpd.conf
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
DirectoryIndex index.php index.html
⑨配置虚拟主机支持使用fastcgi
在相应的虚拟主机中添加类似如下两行：
ProxyRequests Off
ProxyPassMatch ^/(.*\.php)$ fcgi://IP:9000/PATH/TO/DOCUMENT_ROOT/$1 #把以.php结尾的文件请求发送到php-fpm进程，php-fpm至少需要知道运行的目录和URI。注意：这里的 DOCUMENT_ROOT 只是php文件的存放路径，可以不是httpd的站点根目录。实际环境中，php-fpm与httpd多位于不同的主机上，动态资源部署在php-fpm服务器上。
例如：
vim /etc/httpd24/httpd.conf
#DocumentRoot "/usr/local/apache/htdocs" #将中心主机注释掉
Include /etc/httpd24/extra/httpd-vhosts.conf #把虚拟主机配置文件包含进来
vim /etc/httpd24/extra/httpd-vhosts.conf
<VirtualHost *:80>
ServerNAME www.inception.com
DocumentRoot /web/hosta
ProxyRequests off #关闭正向代理
ProxyPassMatch ^/(.*\.php)$ fcgi://192.168.30.20:9000/web/hosta/$1
<Directory "/web/hosta">
Options Index FollowSymLinks
AllowOverride None
Require all granted
</Directory>
</VirtualHost>
⑩编辑测试页面测试
[root@node2 ~]# mv php-5.4.26 php-5.4.26.bac
[root@node2 ~]# tar -xf php-5.4.26.tar.bz2
[root@node2 ~]# cd php-5.4.26

Reloading httpd:起初提示php连接mysql失败：

3、构建分离式LAMP注意事项
①动态资源部署于应用程序服务器(php-fpm)，静态资源部署于web服务器；
②php以fpm方式工作时，不会被编译成httpd的模块，因此，无须在httpd的配置文件中启用LoadModule；
③编译php时，需要连接mysql或其它数据库管理系统时，需要启用其相关的驱动模块；
④php与mysql不在同一节点，连接mysql的用户账号要有远程访问权限；
四、phpadmin
phpMyAdmin是一个用PHP编写的软件工具，可以通过web方式控制和操作MySQL数据库。
[root@node2 ~]# unzip phpMyAdmin-4.0.5-all-languages.zip -d /web/htdocs/ ... [root@node2 ~]# cd /web/htdocs [root@node2 htdocs]# mv phpMyAdmin-4.0.5-all-languages pma [root@node2 htdocs]# cd pma [root@node2 pma]# cp config.sample.inc.php config.inc.php #给phpadmin提供配置文件 [root@node2 pma]# vim config.inc.php ... /* * This is needed for cookie based authentication to encrypt password in * cookie */ $cfg['blowfish_secret'] = 'a8b7c6degierog'; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */ /* * Servers configuration */ $i = 0; /* * First server */ $i++; /* Authentication type */ $cfg['Servers'][$i]['auth_type'] = 'cookie'; /* Server parameters */ $cfg['Servers'][$i]['host'] = 'localhost'; $cfg['Servers'][$i]['connect_type'] = 'tcp'; $cfg['Servers'][$i]['compress'] = false; /* Select mysql if your server does not have mysqli */ $cfg['Servers'][$i]['extension'] = 'mysqli'; $cfg['Servers'][$i]['AllowNoPassword'] = false; ...
