注意：apache默认的程序目录是/var/www/html

权限设置：chown apache.apache -R /var/www/html

2.3 mysql 配置

创建用户istore

create user istore@localhost idenified by '1234';

grant all privileges on *.* to istore@localhost;

flush privileges;

3 安装owncloud

将owncloud安装包下载后复制到/var/www/html目录，修改owncloud的目录权限。在浏览器中输入ip:port/owncloud，按照提示安装即可。

4、问题与解决办法

4.1 问：yum install不能安装软件。

答：

a、检查了一下，原来是机器没有联网（囧）

b、更新源。方法：http://www.oicto.com/centos-yum-163-sohu/

4.2 问：打开浏览器输入网址后，页面空白

答：查询了apache的日志（这个非常重要），日志目录为/var/log/httpd/,里面的error_log文件，错误显示不能解析一些字符，上网查了一下，原来是php的版本低，要5.3以上。下面是升级php的过程：

Install the extra repositories

The first step requires downloading and installing some RPM files that contain the additional repository definitions, which we'll do with the rpm command:

sudo rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpmsudo rpm -Uvh http://repo.webtatic.com/yum/centos/5/latest.rpm

Once installed you should see some additional repository definitions under the /etc/yum.repos.d directory.

$ ls -1 /etc/yum.repos.d/epel* /etc/yum.repos.d/webtatic.repo/etc/yum.repos.d/epel.repo/etc/yum.repos.d/epel-testing.repo/etc/yum.repos.d/webtatic.repo

Enable the webtatic repository

The webtatic repository provides a variety of up-to-date packages that are useful or are a requirement for many popular web-based services.  That means it generally is not a bad idea to enable the webtatic repository by default.

First, open the /etc/yum.repos.d/webtatic.repo repository file using a text editor of your choice,

sudo vim /etc/yum.repos.d/webtatic.repo

Edit the [webtatic] section of the file so that the enabled option is set to 1.  This will enable the remi repository.

[webtatic]name=Webtatic Repository $releasever - $basearch#baseurl=http://repo.webtatic.com/yum/centos/5/$basearch/mirrorlist=http://repo.webtatic.com/yum/centos/5/$basearch/mirrorlistenabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-webtatic-andy

Installing the PHP 5.3 packages

This section will aim to install PHP 5.3 and any relevant additional modules that may be required. If you are upgrading from an older PHP version to PHP 5.3 please skip to the next section.

The following is an example of a single-shot command of the installation of PHP 5.3 and some common modules:

$ sudo yum install php php-cli php-gd php-mysql php-mbstring

The following is a sample trace output (make note of the package version and the repository):

To search for available PHP-related packages we can run the following command:

yum search php

Typically the names of php modules begin with php-. Be careful about any packages that start with php53- as these will conflict with the webtatic versions.

Once you've installed PHP and any required supporting modules, skip to the "Last Steps" section below.

Upgrading to PHP 5.3 packages

If you already have PHP installed the upgrade steps are slightly different.

Warning: Before performing this upgrade please take the time to do a full backup of your system. The upgrade should generally be straightforward, but this will depend on the existing package state of your system.

To upgrade php, run:

$ rpm -q phpphp-5.1.6-27.el5_5.3$ sudo yum upgrade php...Dependencies Resolved=================================================================================== Package                  Arch        Version                      Repository                                                                              Size===================================================================================Updating: php                     x86_64     5.3.20-1.w5              webtatic     1.4 MInstalling for dependencies:...Updating for dependencies: php-cli                 x86_64     5.3.20-1.w5              webtatic     2.6 M php-gd                  x86_64     5.3.20-1.w5              webtatic     108 k php-mbstring            x86_64     5.3.20-1.w5              webtatic     1.2 M php-mysql               x86_64     5.3.20-1.w5              webtatic      91 kTransaction Summary===================================================================================...$ rpm -q phpphp-5.3.20-1.w5

The above commands will check the installed PHP version then update the existing php package and any associated packages to the 5.3 version in the webtatic and epel repositories.

Last steps

At this point you should have PHP 5.3 installed using the webtatic package repository. The last thing to do is to restart apache if it is currently running so that the new PHP version is loaded.

$ sudo /etc/init.d/httpd restart

A quick confirmation from the terminal should let you check the PHP version:

$ php -vPHP 5.3.20 (cli) (built: Dec 20 2012 18:11:02) Copyright (c) 1997-2012 The PHP GroupZend Engine v2.3.0, Copyright (c) 1998-2012 Zend Technologies

安装之后页面出来了，但是提示php 的dom module没有安装，执行命令yum install php-xml，问题解决。
