心血來潮，將Wordpress從一台主機移到另一台主機(之前想做沒做，把原本獨立主機再挪出來另作他用)，步驟：

1. 將Wordpress網站建立tar ball,  tar -xvf wp.tar ./wp/8
2. 使用wget，將網站tar檔複製到新位置
3. 解tar ball
4. 將資料庫中所有的表格以SQL方式匯出，檔案太大，則進mysql，以soruce wp.sql方式進行匯入。

如果Domain URL不變的話，問題比較單純，底下是url變更下的處理方式：

UPDATE wp_options SET option_value = replace(option_value, 'http://www.oldurl', 'http://www.newurl') WHERE option_name = 'home' OR option_name = 'siteurl';

UPDATE wp_posts SET guid = replace(guid, 'http://www.oldurl','http://www.newurl');

UPDATE wp_posts SET post_content = replace(post_content, 'http://www.oldurl', 'http://www.newurl');

UPDATE wp_postmeta SET meta_value = replace(meta_value,'http://www.oldurl','http://www.newurl');

出現404 not found, 接著處理.htaccess，變更目錄 (由舊目錄改成新目錄)
