lamp的实现
lamp组合
L: Linux, A: apache (httpd), M: MySQL (MariaDB), P (php, python, perl, ruby)
下面是基于rpm包的格式来实现lamp的。
php-5.3.3-46.el6_6.x86_64
httpd-2.2.15-47.el6.centos.x86_64
mysql-5.1.73-5.el6_6.x86_64
先在centso6.6上安装以上程序包。
1.php的相关文件，它和httpd的结合是模块化的。php只是一个模块，所以无需启动服务
[root@lys htdocs]# rpm -ql php
/etc/httpd/conf.d/php.conf
/usr/lib64/httpd/modules/libphp5.so
/var/lib/php/session
/var/www/icons/php.gif
2.启动httpd，查看php模块
[root@lys ~]# /usr/sbin/httpd -M

php5_module (shared) php的模块已加载了
ssl_module (shared)
3.在httpd的根目录下新建一个已php结尾的文件。即在/vhosts/a.com/htdocs，新建index.php
[root@lys htdocs]# cat index.php
<h1>www.a.com</h1>
<?php
phpinfo();
?>
4.在浏览器打开测试index.php
出现这个界面说明php模块已加载在httpd中了。
5.接下来就要安装mysql，要想php能连接mysql，必须先安装php-mysql这个程序包。
6.yum install php-mysql -y
[root@lys htdocs]# yum info php-mysql
Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
* base: mirrors.btte.net
* extras: mirror.neu.edu.cn
* updates: mirror.neu.edu.cn
Installed Packages
Name : php-mysql
Arch : x86_64
Version : 5.3.3
Release : 46.el6_6
Size : 216 k
Repo : installed
From repo : updates
Summary : A module for PHP applications that use MySQL databases
URL : http://www.php.net/
License : PHP
Description : The php-mysql package contains a dynamic shared object that will add
: MySQL database support to PHP. MySQL is an object-relational database
: management system. PHP is an HTML-embeddable scripting language. If
: you need MySQL support for PHP applications, you will need to install
: this package and the php package.
7.安装完成php-mysql后，重新加载一下httpd，看phpinfo页面中是否有了mysql相关的说明。如果有说明连接数据库成功了。
8.现在安装mysql，因为我们需要连接的是mysql服务器，所以这里我们需要安装是mysql-server-5.1.73-5.el6_6.x86_64。mysql-5.1.73-5.el6_6.x86_64这是客户端。启动服务，并查看端口。
通过上面的步骤，我们的lamp环境已然搭建完毕。接下来我们在lamp中部署WordPress和phpmyadmin。
下载程序包
wordpress-4.3.1-zh_CN.zip
phpMyAdmin-4.4.15-all-languages.zip
分别解压到httpd的根目录下
tar xf wordpress-4.3.1-zh_CN.zip
[root@lys htdocs]# cd wordpress
[root@lys wordpress]# ll

-rw-r--r-- 1 root root 25124 Sep 3 11:33 wp-signup.php
-rw-r--r-- 1 root root 4035 Sep 3 11:33 wp-trackback.php
-rw-r--r-- 1 root root 3055 Sep 3 11:33 xmlrpc.php
我们编辑一下wp-config-sample.php，
cp wp-config-sample.php wp-config.php
vim wp-config.php 只需编辑以下3个地方，其他暂时不管
define('DB_NAME', 'wpdb');
define('DB_USER', 'wpuser');
define('DB_USER', 'wpuser');
然后创建wpdb数据库，并授权用户可以访问这个数据库
mysql> CREATE DATABASE wpdb;
GRANT ALL ON wpdb.* TO 'wpuser'@'127.0.0.1' IDENTIFIED BY 'wppass'
GRANT ALL ON wpdb.* TO 'wpuser'@'localhost' IDENTIFIED BY 'wppass'
mysql>FLUSH PRIVILEGES;
输入用户名和密码即可登录。
至于https的认证，这里简单介绍一下，由于之前已做了基于虚拟主机www.a.com的https认证，所以这里只需要把wordpress放入到/vhosts/a.com/htdocs路径下，就可基于https协议访问了。
tar xf phpMyAdmin-4.4.15-all-languages.zip
cd phpMyAdmin-4.4.15-all-languages
如果直接在浏览器中访问http://192.168.108.6/phpMyAdmin-4.4.15-all-languages/会报错，提示mbstring么有安装，所以必须要安装php-mbstring程序包。
yum install php-mbstring -y
[root@lys htdocs]# service httpd reload
在这里输入用户名和密码即可登录成功。
