链接表的附加功能尚未激活-如何解决phpmyadmin链接表的附加功能尚未激活

phpmyadmin配置的时候报了一个错误：phpmyadmin链接表的附加功能尚未激活。登陆phpmyadmin后，会在底部显示“链接表的附加功能尚未激活。要查出原因，请点击此处。”的提示。

网上虽然有解决方法，但是不够详细，对与新手来说还是一头雾水。自己折腾了几个小时，才得以解决，下面列出解决phpmyadmin链接表的附加功能尚未激活错误的具体步骤

步骤1：使用Mysql管理员帐号通过phpmyadmin登陆，然后点击“导入”，然后点击“浏览”按钮，找到phpmyadmin文件夹下的scripts文件夹里的一个名为create_tables.sql的文件。(如下图)

或者直接运行如下代码（效果和上面的操作是一样的）：

-- --------------------------------------------------------
-- SQL Commands to set up the pmadb as described in Documentation.html.
--
-- This file is meant for use with MySQL 5 and above!
--
-- This script expects the user pma to already be existing. If we would put a
-- line here to create him too many users might just use this script and end
-- up with having the same password for the controluser.
--
-- This user "pma" must be defined in config.inc.php (controluser/controlpass)  
--
-- Please don't forget to set up the tablenames in config.inc.php

步骤2：打开phpmyadmin文件夹，找到名为config.inc.php的文件，使用文本编辑工具（不推荐使用记事本，建议使用 win2003自带写字板之类的工具）打开该文件。对其进行修改。

/* Advanced phpMyAdmin features */
 // $cfg['Servers'][$i]['pmadb'] = 'phpmyadmin';
 //  $cfg['Servers'][$i]['bookmarktable'] = 'pma_bookmark';
 //  $cfg['Servers'][$i]['relation'] = 'pma_relation';
 // $cfg['Servers'][$i]['table_info'] = 'pma_table_info';
 // $cfg['Servers'][$i]['table_coords'] = 'pma_table_coords';
 //  $cfg['Servers'][$i]['pdf_pages'] = 'pma_pdf_pages';
 //  $cfg['Servers'][$i]['column_info'] = 'pma_column_info';
 //  $cfg['Servers'][$i]['history'] = 'pma_history';
 //  $cfg['Servers'][$i]['tracking'] = 'pma_tracking';
 //  $cfg['Servers'][$i]['designer_coords'] = 'pma_designer_coords';

替换成

/* Advanced phpMyAdmin features */
 $cfg['Servers'][$i]['pmadb'] = 'phpmyadmin';
 $cfg['Servers'][$i]['bookmarktable'] = 'pma_bookmark';
 $cfg['Servers'][$i]['relation'] = 'pma_relation';
 $cfg['Servers'][$i]['table_info'] = 'pma_table_info';
 $cfg['Servers'][$i]['table_coords'] = 'pma_table_coords';
 $cfg['Servers'][$i]['pdf_pages'] = 'pma_pdf_pages';
 $cfg['Servers'][$i]['column_info'] = 'pma_column_info';
 $cfg['Servers'][$i]['history'] = 'pma_history';
 $cfg['Servers'][$i]['tracking'] = 'pma_tracking';
 $cfg['Servers'][$i]['designer_coords'] = 'pma_designer_coords';

其实就是取消注释而已，做完以上步骤关闭浏览器重启打开登陆phpmyadmin就可以解决phpmyadmin链接表的附加功能尚未激活的错误了。
