LAMP搭建 （apache2.4 FCGI+php5+mysql5.5）

网络拓扑：


系统及软件版本：

CENTOS 6.5 apache2.4.12 php5.5.8 mysql5.5.44

一、安装APACHE
1.解决依赖 LAMP
yum install gcc gcc-c++ gcc-g77 flex bison autoconf automake bzip2-devel zlib-devel ncurses-devel libjpeg-devel libpng-devel libtiff-devel freetype-devel pam-devel openssl-devel libxml2-devel gettext-devel pcre-devel mysql-devel net-snmp-devel curl-devel perl-DBI

2.安装apr、apr-util

tar zxvf apr-util-1.5.4.tar.gz
tar zxvf apr-1.5.2.tar.gz
cd apr-1.5.2
./configure --prefix=/usr/local/apr
make && make install
cd apr-util-1.5.4
./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr/
make && make install
3.编译安装httpd-2.4.12

./configure --prefix=/usr/local/apache --sysconfdir=/etc/httpd24 --enable-so --enable-ssl --enable-cgi --enable-rewrite --with-zlib --with-pcre --with-apr=/usr/local/apr/ --with-apr-util=/usr/local/apr-util/ --enable-mpms-shared=all --with-mpm=event --enable-modules=most

make && make install
4.启动验证
/usr/local/apache/bin/apachectl
5.
配置启动脚本 cd /etc/init.d/ cp httpd httpd24：复制原有脚本,如果没有就新建 vim httpd24：修改脚本 #!/bin/bash
#

编译PHP如果遇到如下错误：

configure: error: mcrypt.h not found. Please reinstall libmcrypt.则：

yum install epel-release //扩展包更新包
yum update //更新yum源
./configure --prefix=/usr/local/php --with-openssl --enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --enable-sockets --with-mcrypt --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-bz2 --enable-maintainer-zts --with-mysql=mysqlnd --with-pdo-mysql=mysqlnd --with-mysqli=mysqlnd --enable-fpm
make && make install

[root@station79 php-5.4.26]# cp php.ini-production /etc/php.ini
[root@station79 php-5.4.26]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[root@station79 php-5.4.26]# chmod +x /etc/init.d/php-fpm
[root@station79 php-5.4.26]# chkconfig --add php-fpm
[root@station79 php-5.4.26]# chkconfig php-fpm on
[root@station79 php-5.4.26]# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
编辑php-fpm的配置文件：
# vim /usr/local/php/etc/php-fpm.conf
配置fpm的相关选项为你所需要的值，并启用pid文件（如下最后一行）：
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 2
pm.max_spare_servers = 8
pid = /usr/local/php/var/run/php-fpm.pid

说明：pid这里原本是一个相对路径，而且和我们编译安装的位置不一样，所以需要修改，但是，若你在编译php的时候，若没有指定pid文件的存放路径，那你怎么知道pid文件在哪呢？
方法：grep pid /etc/init.d/php-fpm
php_fpm_PID=${prefix}/var/run/php-fpm.pid
其他无效信息已省略...
${prefix}指的是php编译安装的路径，即为/usr/local/php

启动php-fpm
[root@station79 php-5.4.26]# service php-fpm start
Starting php-fpm done

使用如下命令来验正（如果此命令输出有中几个php-fpm进程就说明启动成功了）：
[root@station79 php-5.4.26]# ps aux|grep "php-fpm"|grep -v "grep"
root 4278 0.0 0.4 69468 4604 ? Ss 17:13 0:00 php-fpm: master process (/usr/local/php/etc/php-fpm.conf)
nobody 4279 0.0 0.3 69468 3932 ? S 17:13 0:00 php-fpm: pool www
nobody 4280 0.0 0.3 69468 3936 ? S 17:13 0:00 php-fpm: pool www
nobody 4281 0.0 0.3 69468 3936 ? S 17:13 0:00 php-fpm: pool www
nobody 4282 0.0 0.3 69468 3936 ? S 17:13 0:00 php-fpm: pool www
nobody 4283 0.0 0.3 69468 3936 ? S 17:13 0:00 php-fpm: pool www

默认情况下，fpm监听在127.0.0.1的9000端口，也可以使用如下命令验正其是否已经监听在相应的套接字
[root@station79 php-5.4.26]# ss -tnl|grep ":9000"
LISTEN 0 128 127.0.0.1:9000 *:*

######################Starting##############################
Apache 77
创建站点目录及测试页
# mkdir -p /web/{a.com,b.org}/htdocs
[root@station123 ~]# cd /etc/httpd/extra/
[root@station123 extra]# vim httpd-vhosts.conf
[root@station123 extra]# service httpd graceful
[root@station123 extra]# ss -tnl|grep ":80" |grep -v "grep"
LISTEN 0 128 :::80 :::*
[root@station123 extra]# /etc/init.d/httpd -M #查看已被编译安装的模块

主配置文件相关的操作：
[root@station123 httpd]# vim httpd.conf
# 在httpd主配置文件中将中心主机用"#"注释掉，操作如下行：
#DocumentRoot "/usr/local/apache/htdocs"

# 在默认首页位置添加index.php，这样，服务器被访问的时候，就会先找到index.php，若该文件存在，就停止查找；若该文件不存在，就会继续向右查找，以此类推
<IfModule dir_module>
DirectoryIndex index.php index.html
</IfModule>

# 因为在后面我要在/etc/httpd/extra/httpd-vhosts.conf中,即在扩展配置文件中定义虚拟主机，所以
需要开启Virtual hosts的功能，操作如下2行：
# Virtual hosts 此行是注释不用理会
Include /etc/httpd/extra/httpd-vhosts.conf #此行默认是被注释掉的，要启用它，需将行首的#去掉

添加如下两行：
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
作用：

#若proxy_module和proxy_fcgi_module模块已成功编译进httpd，那么在主配置文件中就会有下面这样两行，
#不过，这两行默认都未被启用，若想启用，将这两行行首的注释去掉
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so

扩展配置文件相关的操作：
[root@station123 httpd]# cd extra
[root@station123 extra]# vim httpd-vhosts.conf
<VirtualHost *:80>
ServerAdmin webadmin@a.com
DocumentRoot "/web/a.com/htdocs"
ServerName www.a.com
ServerAlias a.com
ErrorLog "logs/a.com-error_log"
CustomLog "logs/a.com-access_log" combined
<Directory "/web/a.com/htdocs">
Options None
Require all granted
</Directory>
ProxyRequests Off
ProxyPassMatch ^/(.*\.php)$ fcgi://172.16.251.79:9000/web/a.com/htdocs/$1
</VirtualHost>

<VirtualHost *:80>
ServerAdmin webadmin@b.org
DocumentRoot "/web/b.org/htdocs"
ServerName www.b.org
ServerAlias b.org

Require all granted
</Directory>
ProxyRequests Off
ProxyPassMatch ^/(.*\.php)$ fcgi://172.16.251.79:9000/web/b.org/htdocs/$1
</VirtualHost>

向Apache端/etc/hosts文件中添加域名解析
172.16.251.77 www.a.com a.com www.b.org b.org

因为我们待会要通过宿主机的浏览器，使用域名来访问我们的站点，所以我们也需要修改宿主机的hosts文件，以便支持域名解析功能，(若有DNS就更好了)
路径：C:\Windows\System32\drivers\etc
添加如下行
172.16.251.77 www.a.com www.b.org www.c.com www.d.org
有时候，宿主机上的防火墙可能会阻止我们修改此文件，暂时关闭宿主机上的防火墙即可

78 MySQL端，此时不用进行其他的配置
79 PHP端，配置如下：
[root@station79 ~]# vim /usr/local/php/etc/php-fpm.conf
# 修改监听的地址为PHP所在服务器IP，端口不变，默认是监听127.0.0.1:9000
listen = 172.16.251.79:9000

启动php-fpm服务
[root@station79 php-5.4.26]# service php-fpm restart
Gracefully shutting down php-fpm warning, no pid file found - php-fpm is not running ?
Starting php-fpm done

查看监听的地址是否为本机IP(172.16.251.79),且端口为9000
[root@station79 php-5.4.26]# ss -tnl|grep ":9000"
LISTEN 0 128 172.16.251.79:9000

创建站点目录
[root@station79 php-5.4.26]# mkdir -p /web/{a.com,b.org}/htdocs
[root@station79 php-5.4.26]# cd
[root@station79 ~]# vim /web/a.com/htdocs/index.php
Wecome to www.a.com
<?php
phpinfo();
?>

[root@station79 ~]# vim /web/b.org/htdocs/index.php
Wecome to www.b.org
<?php
phpinfo();
?>

添加完测试页后，其实不需要重启php-fpm服务的

查看php-fpm脚本都支持哪些选项
[root@station79 htdocs]# service php-fpm
Usage: /etc/init.d/php-fpm {start|stop|force-quit|restart|reload|status}

启动php-fpm服务
[root@station79 php-5.4.26]# service php-fpm reload

至此，所有配置工作已完成

现在，我们可通过宿主机的浏览器来访问刚刚我们新建的站点了
www.a.com/ 或 a.com
www.b.org 或 b.org
都可访问相应的站点
结果我已保存成网页，可供大家查看 到目前为止，位于不同主机上的LAMP架构已搭建完毕，不过由于时间有限，我只能先介绍到这里，稍后，我会在此文的基础上继续为大家演示如何使用php加速插件，提高访问速度，以及LAMP架构的优化，使我们的站点逐渐健壮起来。 歉意：此文，尚未仔细排版，有些粗糙，还请各位博友多多包涵，稍后我会对此文重新排版发布的....

下面我将为php程序安装一个加速插件，并使之生效[root@station79 ~]# cd tools/
[root@station79 tools]# tar xf xcache-3.0.3.tar.bz2
[root@station79 tools]# cd xcache-3.0.3[root@station79 xcache-3.0.3]# /usr/local/php/bin/phpize[root@station79 xcache-3.0.3]# ./configure --enable-xcache --with-php-config=/usr/local/php/bin/php-config[root@station79 xcache-3.0.3]# make && make install安装结束时，会出现类似如下行：
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-zts-20100525/
编辑php.ini，整合php和xcache：
首先将xcache提供的样例配置导入php.ini
# mkdir /etc/php.d
# cp xcache.ini /etc/php.d
说明：xcache.ini文件在xcache的源码目录中。

接下来编辑/etc/php.d/xcache.ini早期的xcache版本，找到zend_extension开头的行，修改为如下行：
zend_extension = /usr/local/php/lib/php/extensions/no-debug-zts-20100525/xcache.so
xcache 3.0.3版本，操作如下：[xcache-common]
;; non-Windows example:
extension = /usr/local/php/lib/php/extensions/no-debug-zts-20100525/xcache.so
;; Windows example:
; extension = php_xcache.dll注意：如果php.ini文件中有多条zend_extension(早期版本)或extension(新版本)指令行，要确保此新增的行排在第一位。保存退出，并重启service php-fpm restart访问测试已okMYSQL安装略
