[我的阿里云服务器] —— WorkPress

前言：

WordPress是基于PHP和MYSQL编成的一套博客系统，因此一般会选择LAMP环境来让它最稳定地运行，

这里的LAMP指的是Linux、Apache、MySQL、PHP，我们我的阿里云服务器（二） - 安装LAMP已经介绍过了。

服务器配置（因为处于学习，所以几乎选了最破的配置了）：

1、CPU：单核

2、内存：512M

3、系统盘：Linux送20G，Ubuntu 12.04 64位系统

4、数据盘：10G

5、公网带宽：1M

一、下载WorkPress

WorkPress在www.wordpress.org的网站上面可以下载最新的程序，我们需要把它下载下来，

然后放在apache的目录中就可以了。

首先，使用wget命令：

wget -c http://wordpress.org/latest.tar.gz

这个命令，将lastest.tar.gz下载到当前所在目录，

我们可以使用pwd命令查看当前，所在目录。

然后，使用ls命令查看文件。

pwd    #查看所在目录,一般是root
ls /root    #查看下载到的文件，可以看到latest.tar.gz

二、解压

因为都是在当前目录，所以直接tar解压即可。

使用命令：

tar -xvzf latest.tar.gz

其中：

x 解压缩
v 显示文件名
z 使用 gzip 压缩解压缩
f 基于文件

那么，wordpress就被解压到/root/wordpress中了。

三、添加到apache中

将解压好的文件，复制到apache目录中即可。

cp -rf wordpress /var/www

-r 给出的源文件是一目录文件，此时cp将递归复制该目录下所有的子目录和文件。此时目标文件必须为一个目录名。

-f 删除已经存在的目标文件而不提示。

四、添加数据库

我们需要给wordpress建一个数据库，然后配置给wordpress进行使用。

下面代码,创建一个名字为wordpress的数据库。

mysql -u user -p
Enter password:

create database wordpress;

五、修改配置

我们需要手动配置wordpress对于mysql数据库的部分，wordpress才可以正常使用。

我们刚才已经把数据库创建好了，下面填入有些部分就可以了。

<?php
/**
 * The base configurations of the WordPress.
 *
 * This file has the following configurations: MySQL settings, Table Prefix,
 * Secret Keys, WordPress Language, and ABSPATH. You can find more information
 * by visiting {@link http://codex.wordpress.org/Editing_wp-config.php Editing
 * wp-config.php} Codex page. You can get the MySQL settings from your web host.
 *
 * This file is used by the wp-config.php creation script during the
 * installation. You don't have to use the web site, you can just copy this file
 * to "wp-config.php" and fill in the values.
 *
 * @package WordPress
 */

// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define('DB_NAME', 'wordpress');

/** MySQL database username */
define('DB_USER', 'usert');

/** MySQL database password */
define('DB_PASSWORD', 'password');

/** MySQL hostname */
define('DB_HOST', 'localhost');

/** Database Charset to use in creating database tables. */
define('DB_CHARSET', 'utf8');

/** The Database Collate type. Don't change this if in doubt. */
define('DB_COLLATE', '');

/**#@+
 * Authentication Unique Keys and Salts.
 *
 * Change these to different unique phrases!
 * You can generate these using the {@link https://api.wordpress.org/secret-key/1.1/salt/ WordPress.org secret-key service}
 * You can change these at any point in time to invalidate all existing cookies. This will force all users to have to log in again.
 *
 * @since 2.6.0
 */
define('AUTH_KEY',         'put your unique phrase here');
define('SECURE_AUTH_KEY',  'put your unique phrase here');
define('LOGGED_IN_KEY',    'put your unique phrase here');
define('NONCE_KEY',        'put your unique phrase here');
define('AUTH_SALT',        'put your unique phrase here');
define('SECURE_AUTH_SALT', 'put your unique phrase here');
define('LOGGED_IN_SALT',   'put your unique phrase here');
define('NONCE_SALT',       'put your unique phrase here');

/**#@-*/

/**
 * WordPress Database Table prefix.
 *
 * You can have multiple installations in one database if you give each a unique
 * prefix. Only numbers, letters, and underscores please!
 */
$table_prefix  = 'wp_';

/**
 * WordPress Localized Language, defaults to English.
 *
 * Change this to localize WordPress. A corresponding MO file for the chosen
 * language must be installed to wp-content/languages. For example, install
 * de_DE.mo to wp-content/languages and set WPLANG to 'de_DE' to enable German
 * language support.
 */
define('WPLANG', '');

/**
 * For developers: WordPress debugging mode.
 *
 * Change this to true to enable the display of notices during development.
 * It is strongly recommended that plugin and theme developers use WP_DEBUG
 * in their development environments.
 */
define('WP_DEBUG', false);

/* That's all, stop editing! Happy blogging. */

/** Absolute path to the WordPress directory. */
if ( !defined('ABSPATH') )
        define('ABSPATH', dirname(__FILE__) . '/');

/** Sets up WordPress vars and included files. */
require_once(ABSPATH . 'wp-settings.php');

大功告成，现在访问http://服务器所在Ip或域名/wordpress。

成功显示，那么我们就搞定了。

六、其他

1、代码语法高亮

安装插件SyntaxHighlighter Evolved。然后在写博文时对代码添加标签即可。

Shortcode Parameters

These are the parameters you can pass to the shortcode and what they do. For the booleans (i.e. on/off), pass true/1 or false/0.

lang or language — The language syntax to highlight with. You can alternately just use that as the tag, such as [php]code[/php].

Click here for a list of valid tags (under "aliases").
autolinks — Toggle automatic URL linking.
classname — Add an additional CSS class to the code box.
collapse — Toggle collapsing the code box by default, requiring a click to expand it. Good for large code posts.
firstline — An interger specifying what number the first line should be (for the line numbering).
gutter — Toggle the left-side line numbering.
highlight — A comma-sperated list of line numbers to highlight. You can also specify a range. Example: 2,5-10,12
htmlscript — Toggle highlighting any extra HTML/XML. Good for when you're mixing HTML/XML with another language, such as having PHP inside an HTML web page.

The above preview has it enabled for example. This only works with certain languages.
light — Toggle light mode which disables the gutter and toolbar all at once.
padlinenumbers — Controls line number padding. Valid values are false (no padding), true (automatic padding), or an integer (forced padding).
title (v3 only) — Sets some text to show up before the code. Very useful when combined with the collapse parameter.
toolbar — Toggle the toolbar (buttons in v2, the about question mark in v3)
wraplines (v2 only) — Toggle line wrapping.
Some example shortcodes:

[php]your code here[/php]
[css autolinks="false" classname="myclass" collapse="false" firstline="1" gutter="true" highlight="1-3,6,9" htmlscript="false"

light="false" padlinenumbers="false" smarttabs="true" tabsize="4" toolbar="true" title="example-filename.php"]your code here[/css]
[code lang="js"]your code here[/code]
[sourcecode language="plain"]your code here[/sourcecode]

举例：

[c]c语言代码[/c]

[php]php代码[/php]

有一些没有，例如xaml，可以用xml替换

[xml]类xml代码[/xml]

问题一、上传附件失败

错误提示：Unable to create directory wp-content/uploads/2013/...

解决办法：在wp-content/目录下，建立uploads目录，然后提升uploads目录权限。

mkdir /var/www/wordpresss/wp-content/uploads
chmod 777 -R /var/www/wordpress/wp-content/uploads

解决问题。

问题二、安装主题失败

在安装的过程中，一直出现can not create directory /var/www/wordpress/wp-content/uploads/../themes等错误。

虽然chmod 777 /var/www/wordpress/wp-content，但是没有效果。

解决办法：

mkdir /var/www/wordpress/wp-content/themes
chmod 777 -R /var/www/wordpress/wp-content/themes

也不知道为什么，反正这样自己创建这个目录后，就好了。
