Linux下搭建LAMP是经典的不能再经典的中小企业站点构建平台。它的全称是Linux+Apache+Mysql+PHP，常用来搭建动态网站，本身都是各自独立的程序，但是因为常被放在一起使用，拥有了越来越高的兼容度，共同组成了一个强大的Web应用程序平台。因此在网络上也有比叫有名的LAMP一键安装解决方案。但是对于运维人员来讲，有必要了解其完成的安装过程。本文主要描述基于CentOS 6 下使用yum方式来快速构建LAMP平台(Linux安装忽略)。

一、准备yum源(本文使用了163镜像)

# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo -P /etc/yum.repos.d/# yum clean all# yum makecache

二、安装apache httpd

详细可以参考：Linux下安装Apache httpd

###检查是否已安装httpd# rpm -qa|grep httpd        httpd-tools-2.2.15-45.el6.centos.x86_64        httpd-2.2.15-45.el6.centos.x86_64# yum -y install httpd   ###此时我们看到httpd的小版本从45变成了53# rpm -qa|grep httpd        httpd-tools-2.2.15-53.el6.centos.x86_64        httpd-2.2.15-53.el6.centos.x86_64###查询生成的相关配置文件# rpm -qc httpd|grep conf        /etc/httpd/conf.d/welcome.conf        /etc/httpd/conf/httpd.conf        /etc/httpd/conf/magic        /etc/sysconfig/htcacheclean        /etc/sysconfig/httpd###启动httpd# /etc/init.d/httpd start        Starting httpd:                                            [  OK  ]# netstat -nltp|grep 80        tcp        0      0 :::80          :::*      LISTEN      7621/httpd###验证web服务# curl -I http://localhost        HTTP/1.1 403 Forbidden        Date: Tue, 12 Jul 2016 09:25:15 GMT        Server: Apache/2.2.15 (CentOS)        Accept-Ranges: bytes        Content-Length: 4961        Connection: close        Content-Type: text/html; charset=UTF-8###编写一个php页面测试# echo "> > 
This is a php test page.> > phpinfo();> ?>> ">>/var/www/html/index.php  ###测试结果为phpinfo函数没有被解释# curl http://localhost/index.php                
This is a php test page.                phpinfo();        ?>        

三、安装php

###安装php，同时会安装依赖包# yum install php
        Installing:
         php                      x86_64     5.3.3-47.el6      base     1.1 M
        Installing for dependencies:
         php-cli                  x86_64     5.3.3-47.el6      base     2.2 M
         php-common               x86_64     5.3.3-47.el6      base     530 k

###查看php安装清单 # rpm -ql php
        /etc/httpd/conf.d/php.conf
        /usr/lib64/httpd/modules/libphp5.so
        /var/lib/php/session
        /var/www/icons/php.gif 

###查看php的配置文件 # grep -vE "^#|^$" /etc/httpd/conf.d/php.conf 
        
          LoadModule php5_module modules/libphp5.so
        
          LoadModule php5_module modules/libphp5-zts.so
        
        AddHandler php5-script .php
        AddType text/html .php
        DirectoryIndex index.php

###在上面的配置文件中，由于php以模块化方式与httpd结合工作，根据httpd的mpm模式不同，###其所需要的php模块格式有所不同；    prefork模式使用libphp5模块    worker和event模式则使用libphp5-zts模块###重启httpd已使得php模块生效# /etc/init.d/httpd configtest
        Syntax OK

# /etc/init.d/httpd restart
        Stopping httpd:                 [  OK  ]
        Starting httpd:                 [  OK  ]

###验证php模块已经被加载# httpd -M |grep php
        php5_module (shared)

###验证php页面 # curl http://localhost/index.php|more
        
        
This is a php test page.
        span> PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN""DTD/xhtml1-transitional.dtd">
        
        

四、安装mysql

# rpm -qa|grep mysql
        mysql-libs-5.1.73-5.el6_6.x86_64

# yum install mysql-server  # rpm -qa|grep mysql      
        mysql-5.1.73-7.el6.x86_64
        mysql-libs-5.1.73-7.el6.x86_64
        mysql-server-5.1.73-7.el6.x86_64

###查看mysql安装产生的文件# rpm -ql mysql-server# rpm -ql mysql# more /etc/my.cnf
        [mysqld]
        datadir=/var/lib/mysql
        socket=/var/lib/mysql/mysql.sock
        user=mysql
        # Disabling symbolic-links is recommended to prevent assorted security risks
        symbolic-links=0        [mysqld_safe]
        log-error=/var/log/mysqld.log
        pid-file=/var/run/mysqld/mysqld.pid

# /etc/init.d/mysqld start# /usr/bin/mysqladmin -u root password '***'# mysql -uroot -p
mysql> show variables like 'port';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| port          | 3306  |
+---------------+-------+

###安装php连接mysql驱动#   yum install php-mysql###查看安装完毕后生产的文件# rpm -ql php-mysql
        /etc/php.d/mysql.ini      ### Author : Leshami
        /etc/php.d/mysqli.ini     ### Blog   : http://blog.csdn.net/leshami
        /etc/php.d/pdo_mysql.ini
        /usr/lib64/php/modules/mysql.so
        /usr/lib64/php/modules/mysqli.so
        /usr/lib64/php/modules/pdo_mysql.so

###测试到mysql的连接#vim  /var/www/html/connmysql.php
'127.0.0.1','root','***');
    if ($conn)
        echo "succ";
    else
        echo "failure";
    mysql_close();
?>

# curl http://localhost/connmysql.php
        succ

五、小结

1、apache httpd与php之间的衔接是通过模块化的方式来实现。
2、对于perfork模式使用libphp5模块，worker和event模式则使用libphp5-zts模块。
3、php与mysql则通过安装php-mysql包来实现php到mysql的访问。

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });

以上就介绍了 Linux 6 下yum方式安装配置LAMP平台，包括了方面的内容，希望对PHP教程有兴趣的朋友有所帮助。
