编译安装php-5.4.40
场景一：php编译为httpd的模块；
编译安装httpd-2.4: apr,apr-util httpd-2.4
mariadb-5.5.42 注意：不用使用5.5.40除非自己去打补丁;与php结合会有问题;
安装php： 额外安装：libxml2-devel, libmcrypt-devel, bzip-devel 方法一： 我挂载的是CentOS-6.6-x86_64-bin-DVD1 这个安装光盘； # mount /dev/cdrom /media # cd /media/Package # rpm -ivh libxml2-devel-2.6.26-2.1.2.1.x86_64.rpm # rpm -ivh zlib-devel-1.2.3-3.x86_64.rpm
# yum install -y bzip2-devel # yum -y install libmcrypt-devel 方法二： # yum install -y libxml2-devellibmcrypt-devel bzip-devel
注意：如果httpd使用的mpm为worker或event,还应该额外使用 --enable-maintainer-zts选项
# tar xf php-5.4.40.tar.bz2 # cd php-5.4.40
#./configure --prefix=/usr/local/php --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-apxs2=/usr/local/apache/bin/apxs --enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --enable-sockets --with-mcrypt --with-bz2 --with-config-file-path=/etc/php/php.ini --with-config-file-scan-dir=/etc/php.d/
#make
#make install
# mkdir /etc/php
# ls /etc/php
# cp php.ini-production /etc/php/php.ini
# vim /etc/php/php.ini
找到跟时区相关的项目：修改为一下内容
date.timezone = Asia/Shanghai
# service httpd24 restart
# httpd -M 可以看到模块会被加载进来;
# vim /usr/local/apache/htdocs/index.php
添加如下内容：
<?php
phpinfo();
?>
# vim /etc/httpd24/httpd.conf
在AddType 附加添加下面类容：
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
<IfModule dir_module>
添加成这样：DirectoryIndex index.php index.html
这是有优先顺序的,把index.php 放在第一项;
# service httpd24 reload
联系MYSQL：
# vim /usr/local/apache/htdocs/index.php
<?php
$link = mysql_connect('127.0.0.1','root','');
if ($link)
echo "OK";
else
echo "Failure";
mysql_close()
?>
# service mysqld stop
# service mysqld start
安装：phpMyAdmin
# unzip phpMyAdmin-4.0.5-all-languages.zip
# mv phpMyAdmin-4.0.5-all-languages /usr/local/apache/htdocs/pma
# cd /usr/local/apache/htdocs/pma
# cp config.sample.inc.php config.inc.php
#vim config.inc.php
$cfg['blowfish_secret'] = '最好生成一个随机串放进来(随便写点什么都可以)'
此时就可以在浏览器中访问pma了；
此时Mysql服务器root用户的密码是空；需要设定密码才能登陆pma；
# mysql
>SET PASSWORD FOR 'root'@'localhost' = PASSWORD('mgeedu');
>SET PASSWORD FOR 'root'@'127.0.0.1' = PASSWORD('mgeedu');
> SHOW GLOBAL VARIABLES LIKE '%skip%';
因为MySQL 服务器会进行反向解析;所有最好设定两个密码；
如果不想让MySQL 服务器进行反向解析 可以使用下面的方法，而且方向解析会降低Mysql服务器的性能,所有最好把它关闭；
# vim /etc/mysql/my.cnf
在 [mysqld] 下面增加一行：
skip_name_resolve = on 就可以不进行反向解析了;
# service mysqld restart
但是现在登录mysql 服务器是不能直接登录的；
[iyunv@localhost pma]# mysql
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
只能使用下面的方法登录：
[iyunv@localhost pma]# mysql -uroot -p
Enter password:
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 3
Server version: 5.5.43-MariaDB-log MariaDB Server
此时就可以用root用户访问pma.
现在可以进行一下压力测试：(用ab命令做压力测试)

这是访问php页面的速度; 一般访问静态页面的速度会更加快;
现在安装xcache 加速php的访问速度：
# tar xf xcache-3.2.0.tar.bz2
# cd xcache-3.2.0
xcache 很独特,解压后是没有 config 文件的,需要如下步骤把config配置文件解压出来;
# /usr/local/php/bin/phpize
Configuring for:
PHP Api Version: 20100412
Zend Module Api No: 20100525
Zend Extension Api No: 220100525
# ll 现在就可以看到config 文件了；
# ./configure --enable-xcache --with-php-config=/usr/local/php/bin/php-config
# make && make install
会生成这个文件：
# mkdir /etc/php.d
# cp xcache.ini /etc/php.d
# cd /etc/php.d
# vim xcache.ini
修改为如下内容：
extension = /usr/local/php/lib/php/extensions/no-debug-zts-20100525/xcache.so
# service httpd24 restart
# vim /usr/local/apache/htdocs/index.php
修改为如下内容：
<php
Phpinfo(); ?>
# service httpd24 restart
Xcache模块已经被加载进了PHP,现在来测试是否加速了php页面的访问速度读：

xcache 会给php的访问速度带来性能的提升；
场景二：php以fpm工作为独立守护进程：
(还是在上面的实验环境中进行,所以需要修改一下)
# service httpd24 stop
# cd /etc/httpd24/
[iyunv@localhost httpd24]# ls
extra httpd.conf httpd.conf.bak magic mime.types original ssl
# mv httpd.conf httpd.conf.php如果以后还想使用,还可以还原回来；
# cp httpd.conf.bak httpd.conf将原来备份的配置文件复制回来(备份很重要)
# service httpd24 start
现在重新编译php：
# mv php-5.4.40 php-5.4.40.module 以后还要使用的话,可以还原回来;
#rm -rf /usr/local/php/ /etc/php /etc/php.d/删除原来使用的文件；
# tar xf php-5.4.40.tar.bz2
# cd php-5.4.40
# ./configure --prefix=/usr/local/php --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config
--enable-fpm --enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir
--with-zlib --with-libxml-dir=/usr --enable-xml --enable-sockets --with-mcrypt --with-bz2
--with-config-file-path=/etc/php/php.ini --with-config-file-scan-dir=/etc/php.d/
与php安装mysql模块不同的是：
--with-mysqli=/usr/local/mysql/bin/mysql_config这一项换成了--enable-fpm
# make && make install
# mkdir /etc/php /etc/php.d
# cp php.ini-production /etc/php/php.ini
为php-fpm提供SysV init脚本,并将其添加至服务列表：
# 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
# cd /usr/local/php/etc/
# cp php-fpm.conf.default php-fpm.conf
# vim php-fpm.conf
修改如下配置：
pid = /usr/local/php/var/run/php-fpm.pid
error_log = /var/log/php-fpm.log
要启动的最大并发进程：
pm.max_children = 200
刚刚启动服务时候启动多少个进程：
pm.start_server = 5
最小空闲几个服务进程：
pm.min_space_server = 2
最多空闲几个服务进程：
pm.max_space_servers = 5 这个最起码要大于pm.start_server = 5 的个数
# service php-fpm start
Starting php-fpm done
# ss -tnl 此时 9000 端口已经打开了;
配置httpd 服务：
# cd /etc/httpd24/
# vim httpd.conf
启动httpd的相关模块：
在apache 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,因此两个模块都要加载。
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so
配置虚拟主机支持使用fcgi:
在相应的虚拟主机中添加类似如下两行;(在最后添加一下2行)
ProxyRequests Off关闭正向代理;
ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/usr/local/apache/htdocs/$1
================================================================
如果使用的是虚拟主机：要把下面2项 放入<VirtualHost *:80> 下即可
ProxyRequests Off关闭正向代理;
ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/PATH/TO/DOCUMENT_ROOT/$1
================================================================
# httpd -t
# service httpd24 reload
# httpd -M
# cd /usr/local/apache/htdocs/
# vim index.php
添加如下内容：
<?
phpinfo();
?>
# vim /etc/httpd24/httpd.conf
增加此内容：
DirectoryIndex index.php index.html
# service httpd24 reload
用AB压力测试工具进行压力测试：
[iyunv@localhost htdocs]# ab -n 100 -c 5 http://172.16.8.101/pam/index.php

需要把服务放置在不通主机上，这样才能看到真正的性能;
下面配置xcache 加速php页面的访问速度：
删除场景一时候使用的xcache
# rm -rf xcache-3.2.0
# tar xf xcache-3.2.0.tar.bz2
# cd xcache-3.2.0
# /usr/local/php/bin/phpize
Configuring for:
PHP Api Version: 20100412

# ./configure --enable-xcache --with-php-config=/usr/local/php/bin/php-config
# make && make install
# cp xcache.ini /etc/php.d/
# cd /etc/php.d/
# vim xcache.ini
修改如下配置：
extension = /usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/xcache.so
# service php-fpm restart
使用了xcache 做测试：
