安装指南

创建数据库

mysqladmin -u root -p create wordpress 或
mysql>create database wordpress;
mysql>GRANT ALL PRIVILEGES ON wordpress.* TO wordpress@localhost IDENTIFIED BY 'wordpress';
mysql>flush privileges;

设置 wp-config.php

cp wp-config-sample.php wp-config.php
// ** MySQL settings ** //
define('DB_NAME', 'wordpress');     // The name of the database
define('DB_USER', 'wordpress');     // Your MySQL username
define('DB_PASSWORD', 'wordpress'); // ...and password
define('DB_HOST', 'localhost');     // 99% chance you won't need to change this value

运行安装向导,完成后续安装
http://localhost/wordpress/wp-admin/install.php

Lighttpd

wp rewrite

Plugins

http://wp-plugins.net/

<?php posts_nav_link(' — ', __('« Previous Page'), __('Next Page »')); ?>

维护

因为 WordPress 会被很多拉圾 comment 侵袭, 所以要定期情理一下数据库, 但一定要小心操作.

delete from wp_comments where comment_post_ID = 33;    
delete from wp_comments where comment_post_ID = 33 and comment_ID ! = 20; 
delete from wp_comments where comment_post_ID = 60 and comment_ID != 20 and comment_ID !=21;

升级

升级到 2.1
For all upgrade paths, such as 1.5.2 to 2.1, or 2.0, 2.0.1, 2.0.2, or 2.0.3, 2.0.4, 2.0.5, 2.06, and  2.0.7 to 2.1, 
http://codex.wordpress.org/Upgrading_WordPress#How_to_Upgrade_in_Five_Steps
Step 1: Backup Database Tables and Files including .htaccess
Step 2: Deactivate Plugins
Step 3: Overwrite Files
这一步我们没有采用删除文件的方式，而是采用安装新版 WordPress 的方式, 将老版本的 wp-config.php copy过来，
Step 4: Run the upgrade script
然后运行新版本的update, 完成升级。这样做的风险比较小。老版本也能运行，这样可以在新版本上根据老版本一点点修改。
Step 5: Reactivate Plugins one by one

升级出错:

WordPress database error: [Unknown column 'user_nickname' in 'field list']
SELECT ID, user_nickname, user_nicename FROM wp_users

处理方式:

alter table wp_users add column user_nickname varchar(250);

Fatal error: Cannot access empty property in wordpress/wp-admin/upgrade-functions.php on line 646

Edit wp-admin/upgrade-functions.php, and edit this line (around line 646):

$all_options->{$option->option_name} = stripslashes($option->option_value);
To read:
if ($option->option_name) $all_options->{$option->option_name} = stripslashes($option->option_value);

返回可登录进入Admin, 也可能包含以下错误:

WordPress database error: [Table 'wordpress.wp_linkcategories' doesn't exist] SELECT cat_id, cat_name FROM wp_linkcategories ==2.5到==2.8.2 今天准备从2.5 Update to 2.8.2

2.1到2.5

从2.1升级到2.5, 目前 http://blogs.huihoo.com 使用的是2.1的wordpress, 而最新版是2.5,中间有2.1.1, 2.1.2, 2.1.3, 2.2, 2.2.1, 2.2.2, 2.2.3, 2.3, 2.3.1, 2.3.2, 2.3.3 版本，我们将采取覆盖老版本、逐步升级的策略。

2.1 -> 2.1.3 OK:)

2.1.3 -> 2.2 OK:)

2.2 -> 2.2.3 OK:)

2.2.3-> 2.3 OK:)

2.3 -> 2.3.3 OK:)

2.3.3 -> 2.5 OK:)

终于从 2.1 升级到 2.5

WordPress MU

WordPress MU : WordPress的多用户版

安装完成后，用 admin登录，

可打开数据库，修改 admin 的密码
update wp_users set user_pass="1a1dc91c907325c69271ddf0c944bc72" where ID=1;
这个是pass的md5值，因此
用 admin/pass 就可以登录成功 :)

WordPress MU on Lighttpd

WordPress MU 会为每个用户建立单独使用的一套表，如 id=1, id=2 的用户

| wp_1_categories     |
| wp_1_comments       |
| wp_1_link2cat       |
| wp_1_links          |
| wp_1_options        |
| wp_1_post2cat       |
| wp_1_postmeta       |
| wp_1_posts          |
| wp_2_categories     |
| wp_2_comments       |
| wp_2_link2cat       |
| wp_2_links          |
| wp_2_options        |
| wp_2_post2cat       |
