对应你当前的系统，查看相应的内容，当前我的环境应该参考Apache 2.x on Unix systems这部分
Apache 2.x on Unix systems
This section contains notes and hints specific to Apache 2.x installs
of PHP on Unix systems.
Warning
We do not recommend using a threaded MPM in production with Apache 2.
Use the prefork MPM, which is the default MPM with Apache 2.0 and 2.2.
For information on why, read the related FAQ entry on using Apache2
with a threaded MPM
The » Apache Documentation is the most authoritative source of
information on the Apache 2.x server. More information about
installation options for Apache may be found there.
The most recent version of Apache HTTP Server may be obtained from
» Apache download site, and a fitting PHP version from the above
mentioned places. This quick guide covers only the basics to get
started with Apache 2.x and PHP. For more information read the » Apache
Documentation. The version numbers have been omitted here, to ensure
the instructions are not incorrect. In the examples below, \'NN\' should
be replaced with the specific version of Apache being used.
There are currently two versions of Apache 2.x - there\'s 2.0 and 2.2.
While there are various reasons for choosing each, 2.2 is the current
latest version, and the one that is recommended, if that option is
available to you. However, the instructions here will work for either
2.0 or 2.2.
1. Obtain the Apache HTTP server from the location listed above, and
unpack it:
gzip -d httpd-2_x_NN.tar.gz
tar -xf httpd-2_x_NN.tar
2. Likewise, obtain and unpack the PHP source:
gunzip php-NN.tar.gz
tar -xf php-NN.tar
3. Build and install Apache. Consult the Apache install documentation
for more details on building Apache.
cd httpd-2_x_NN
./configure --enable-so
make
make install
4. Now you have Apache 2.x.NN available under /usr/local/apache2,
configured with loadable module support and the standard MPM
prefork. To test the installation use your normal procedure for
starting the Apache server, e.g.:
/usr/local/apache2/bin/apachectl start
and stop the server to go on with the configuration for PHP:
/usr/local/apache2/bin/apachectl stop
5. Now, configure and build PHP. This is where you customize PHP with 这里开始就是php的安装，上面说的都是apache
various options, like which extensions will be enabled. Run
./configure --help for a list of available options. In our example
we\'ll do a simple configure with Apache 2 and mysql support.
If you built Apache from source, as described above, the below
example will match your path for apxs, but if you installed Apache
some other way, you\'ll need to adjust the path to apxs accordingly.
Note that some distros may rename apxs to apxs2.
cd ../php-NN
./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql
make
make install
If you decide to change your configure options after installation,
you\'ll need to re-run the configure, make, and make install steps. 如果需要改变设置就重新安装
You only need to restart apache for the new module to take effect.
A recompile of Apache is not needed.
Note that unless told otherwise, \'make install\' will also install
PEAR, various PHP tools such as phpize, install the PHP CLI, and
more.
6. Setup your php.ini
cp php.ini-development /usr/local/lib/php.ini
You may edit your .ini file to set PHP options. If you prefer
having php.ini in another location, use
--with-config-file-path=/some/path in step 5. 自定义配置文件路径
If you instead choose php.ini-production, be certain to read the
list of changes within, as they affect how PHP behaves.
7. Edit your httpd.conf to load the PHP module. The path on the right
hand side of the LoadModule statement must point to the path of the
PHP module on your system. The make install from above may have
already added this for you, but be sure to check.
LoadModule php5_module modules/libphp5.so 在httpd配置文件中添加语句加载php模块
8. Tell Apache to parse certain extensions as PHP. For example, let\'s
have Apache parse .php files as PHP. Instead of only using the
Apache AddType directive, we want to avoid potentially dangerous 只使用AddType指令具有潜在危险
uploads and created files such as exploit.php.jpg from being
executed as PHP. Using this example, you could have any
extension(s) parse as PHP by simply adding them. We\'ll add .php to
demonstrate.
<FilesMatch \\.php$> 正则表达式，匹配所有“.php”结尾的文件名
SetHandler application/x-httpd-php
</FilesMatch>
Or, if we wanted to allow .php, .php2, .php3, .php4, .php5, .php6,
and .phtml files to be executed as PHP, but nothing else, we\'d use
this:
<FilesMatch "\\.ph(p[2-6]?|tml)$">
SetHandler application/x-httpd-php
</FilesMatch>
And to allow .phps files to be handled by the php source filter,
and displayed as syntax-highlighted source code, use this:
<FilesMatch "\\.phps$">
SetHandler application/x-httpd-php-source
</FilesMatch>
mod_rewrite may be used To allow any arbitrary .php file to be
displayed as syntax-highlighted source code, without having to
rename or copy it to a .phps file:
RewriteEngine On
RewriteRule (.*\\.php)s$ $1 [H=application/x-httpd-php-source]
The php source filter should not be enabled on production systems,
where it may expose confidential or otherwise sensitive information
embedded in source code.
9. Use your normal procedure for starting the Apache server, e.g.:
/usr/local/apache2/bin/apachectl start
OR
service httpd restart
Following the steps above you will have a running Apache2 web server
with support for PHP as a SAPI module. Of course there are many more
configuration options available Apache and PHP. For more information
type ./configure --help in the corresponding source tree.
Apache may be built multithreaded by selecting the worker MPM, rather
than the standard prefork MPM, when Apache is built. This is done by
adding the following option to the argument passed to ./configure, in
step 3 above:
--with-mpm=worker
This should not be undertaken without being aware of the consequences
of this decision, and having at least a fair understanding of the
implications. The Apache documentation regarding » MPM-Modules
discusses MPMs in a great deal more detail.
Note:
The Apache MultiViews FAQ discusses using multiviews with PHP.
Note:
To build a multithreaded version of Apache, the target system must
support threads. In this case, PHP should also be built with
experimental Zend Thread Safety (ZTS). Under this configuration, not
all extensions will be available. The recommended setup is to build
Apache with the default prefork MPM-Module.

mysqli扩展技术不仅可以调用MySQL的存储过程、处理MySQL事务，而且还可以使访问数据库工作变得更加稳定。
--with-mysqli=/usr/local/mysql/bin/mysql_config
整合 apache，apxs功能是使用mod_so中的LoadModule指令，加载指定模块到 apache，要求 apache 要打开SO模块
--with-apxs2=/usr/local/apache/bin/apxs
# 选项指令 --with-iconv-dir 用于 PHP 编译时指定 iconv 在系统里的路径，否则会扫描默认路径。

0x03 安装过程
[root@localhost php-5.6.19]# ./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 --enable-xml --enable-sockets --with-apxs2=/usr/local/apache2/bin/apxs --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-bz2 --enable-maintainer-zts
1、按照上面选项编译报错
checking libxml2 install dir... yes
checking for xml2-config path...
configure: error: xml2-config not found. Please check your libxml2 installation.
显示内容是xml2-config找不到，发现libxml2已经安装但是安装文件没有xml2-config，安装libxml2-devel后
[root@localhost php-5.6.19]# rpm -ql libxml2-devel
/usr/bin/xml2-config
……
2、继续编译，报错如下
checking for BZip2 support... yes
checking for BZip2 in default path... not found
configure: error: Please reinstall the BZip2 distribution
安装bzip2-devel
[root@localhost php-5.6.19]# yum install bzip2-devel
3、继续编译，报错如下
checking for specified location of the MySQL UNIX socket... no
configure: error: Cannot find libmysqlclient_r under /usr/local/mysql/.
Note that the MySQL client library is not bundled anymore!
对于这个问题有个比较久远的帖子 http://blog.chinaunix.net/uid-10697776-id-2935536.html有提及，这个方法我没有测试，另一种说就是因为64位的linux的lib路径有问题加上--with-libdir=lib的编译选项，这个试过加上也是同样的编译报错。
最终找到一个可行的办法就是，编译之前，先处理一下mysql的库，默认查找libmysqlclient_r.so，可是mysql默认为libmysqlclient.so，内容完全一样，做个链接即可
# cd /usr/local/mysql/lib/mysql/
# ln -s libmysqlclient.so.15.0.0 libmysqlclient_r.so
最后成功解决，可以make了，视个人系统环境不同，可能编译出错也不同，其时就是少什么库，就安装什么，对于编译错误找到一个总结比较好的帖子http://www.cnblogs.com/alexqdh/archive/2012/11/20/2776017.html

0x03 后续工作
查看apache配置文件，发现已经加载了php模块
LoadModule alias_module modules/mod_alias.so
#LoadModule rewrite_module modules/mod_rewrite.so
LoadModule php5_module modules/libphp5.so
在apache安装目录下modules里面有php安装后新增的libphp5.so
[root@localhost php-5.6.19]# ll /usr/local/apache2/modules/libphp5.so
-rwxr-xr-x. 1 root root 34524225 3月 7 00:12 /usr/local/apache2/modules/libphp5.so
以上即可说明php已经正常安装
1、在apache配置文件添加以下语句，实现php文件调用php模块解析
AddType application/x-httpd-php .php
2、复制php源码根目录下的配置文件到/etc
cp php.ini-production /etc/php.ini
至此php已经可以正常工作了
0x04 测试
因为apache编译安装的网页文件目录为/usr/local/apache2/htdocs
在其中新增php文件测试能否正常解析，新增经典测试语句
[root@localhost php-5.6.19]# cat /usr/local/apache2/htdocs/phpinfo.php
<?php
phpinfo();
?>
测试正常
