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 "
> <html>
> <h1>This is a php test page.</h1>
> <?php
> phpinfo();
> ?>
> </html>">>/var/www/html/index.php  

###测试结果为phpinfo函数没有被解释
# curl http://localhost/index.php
        <html>
        <h1>This is a php test page.</h1>
        <?php
        phpinfo();
        ?>
        </html>

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 
        <IfModule prefork.c>
          LoadModule php5_module modules/libphp5.so
        </IfModule>
        <IfModule worker.c>
          LoadModule php5_module modules/libphp5-zts.so
        </IfModule>
        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
        <html>
        <h1>This is a php test page.</h1>
        <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "DTD/xhtml1-transitional.dtd">
        <html><head>
        <style type="text/css">
        body {background-color: #ffffff; color: #000000;}
              ...........

###切换为使用worker工作模式
# cp /etc/sysconfig/httpd /etc/sysconfig/httpd.bk
# sed -i "s@#HTTPD=/usr/sbin/httpd.worker@HTTPD=/usr/sbin/httpd.worker@g" /etc/sysconfig/httpd
# grep -vE "^#|^$" /etc/sysconfig/httpd
        HTTPD=/usr/sbin/httpd.worker

###从下面的提示中，我们需要使用php5zts模块
# /etc/init.d/httpd restart
        Stopping httpd:                                            [  OK  ]
        Starting httpd: httpd.worker: Syntax error on line 221 of /etc/httpd/conf/httpd.conf: 
        Syntax error on line 9 of /etc/httpd/conf.d/php.conf: Cannot load /etc/httpd/modules/libphp5-zts.so 
        into server: /etc/httpd/modules/libphp5-zts.so: cannot open shared object file: No such file or directory
                                                                   [FAILED]
###安装php-zts模块
# yum -y install php-zts
# rpm -ql php-zts
        /usr/lib64/httpd/modules/libphp5-zts.so

# ps -ef|grep http   ###查看httpd，已经切换为使用worker模式
        root      10339      1  0 04:35 ?        00:00:00 /usr/sbin/httpd.worker
        apache    10341  10339  0 04:35 ?        00:00:00 /usr/sbin/httpd.worker
        apache    10342  10339  0 04:35 ?        00:00:00 /usr/sbin/httpd.worker
        apache    10343  10339  0 04:35 ?        00:00:00 /usr/sbin/httpd.worker
        apache    10344  10339  0 04:35 ?        00:00:00 /usr/sbin/httpd.worker

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
<?php
    $conn = mysql_connect('127.0.0.1','root','***');
    if ($conn)
        echo "succ";
    else
        echo "failure";
    mysql_close();
?>

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