PHPMyadmin是一款非常好用的數據庫管理界面，尤其適合對數據庫操作命令不熟悉的新手。其中PHPMyadmin也有很多的配置項，我們今天就來詳解一下PHPMyadmin的配置文件，也可參考mysql數據庫視頻教程：mysql教程

PHPMyadmin配置文件config.inc.php內容如下，在需要設置的地方增加了相關注釋。

下面我就說下怎么安裝該工具：
1.先到網上下載phpmyadmin，再解壓到可以訪問的web目錄下（如果是虛擬空間，可以解壓后通過ftp等上傳到web目錄下），當然您可以修改解壓后該文件的名稱。
2.配置config文件
打開libraries下的config.default.php文件，依次找到下面各項，按照說明配置即可：
A.訪問網址
引用:
$cfg['PmaAbsoluteUri'] = '';這里填寫phpmyadmin的訪問網址
B.mysql主機信息
引用:
$cfg['Servers'][$i]['host'] = 'localhost'; // html' target='_blank'>MySQL hostname or IP address
填寫localhost或mysql所在服務器的ip地址，如果mysql和該phpmyadmin在同一服務器，則按默認localhost
$cfg['Servers'][$i]['port'] = ''; // MySQL port - leave blank for default port
mysql端口，如果是默認3306，保留為空即可
C.mysql用戶名和密碼
引用:
$cfg['Servers'][$i]['user'] = 'root'; // MySQL user 訪問phpmyadmin使用的mysql用戶名
fg['Servers'][$i]['password'] = ''; // MySQL password (only needed對應上述mysql用戶名的密碼
D.認證方法
引用:
$cfg['Servers'][$i]['auth_type'] = 'cookie';
在此有四種模式可供選擇，cookie，http，HTTP，config
config方式即輸入phpmyadmin的訪問網址即可直接進入，無需輸入用戶名和密碼，是不安全的，不推薦使用。
當該項設置為cookie，http或HTTP時，登錄phpmyadmin需要數據用戶名和密碼進行驗證，,具體如下：
PHP安裝模式為Apache，可以使用http和cookie；
PHP安裝模式為CGI，可以使用cookie
E.短語密碼(blowfish_secret)的設置
引用:
$cfg['blowfish_secret'] = '';
如果認證方法設置為cookie，就需要設置短語密碼，置于設置為什么密碼，由您自己決定，但是不能留空，否則會在登錄phpmyadmin時提示錯誤
好了，到此為止，您已經成功安裝了phpmyadmin，簡單吧，趕快登錄體驗下吧
說明：
該文檔說明的只是安裝phpmyadmin的基本配置，關于config.default.php文件中各個配置參數的詳細說明可以
phpMyAdmin 就是一種 MySQL 數據庫的管理工具，安裝該工具后，即可以通過 web 形式直接管理 MySQL 數據，而不需要通過執行系統命令來管理，非常適合對數據庫操作命令不熟悉的數據庫管理者，下面詳細說明該工具的安裝方法。
一、下載
1、先到站點下載phpMyAdmin 安裝包：http://www.49028c.com/xiazai/gongju/97（安裝包含各種語言all-languages）
2、再解壓到 web 可以訪問的目錄下，如果是虛擬空間，可以解壓后通過 ftp 工具上傳到 web 目錄下，同時您可以修改解壓后該文件的名稱（你可以自定義目錄名稱）。
二、配置
3、打開 /libraries/config.default.php文件（舊版本是根目錄下的config.inc.php文件），用寫字板（不要用記事本，這是UTF8編碼）進行編輯，按照說明配置即可。
4、查找 $cfg['PmaAbsoluteUri']=‘'; // 修改為你將上傳到空間的phpMyAdmin的網址
如：$cfg['PmaAbsoluteUri'] =‘http: // 網站域名/phpmyadmin/';
5、查找 $cfg['Servers'][$i]['host'] =‘localhost'; // 通常用默認，也有例外，可以不用修改
6、查找 $cfg['Servers'][$i]['auth_type'] =‘config'; // 在自己的機子里調試用config；如果在網絡上的空間用cookie.
在此有四種模式可供選擇：cookie，http，HTTP，config
① config 方式即輸入phpMyAdmin 的訪問網址即可直接進入，無需輸入用戶名和密碼，是不安全的，不推薦使用。
② 設置cookie，http，HTTP方式，登錄 phpMyAdmin 需要數據用戶名和密碼進行驗證。
具體如下：PHP 安裝模式為 Apache，可以使用 http 和 cookie；PHP 安裝模式為 CGI，可以使用 cookie。
7、查找 $cfg['Servers'][$i]['user'] = ‘root'; // MySQL用戶名
8、查找 $cfg['Servers'][$i]['password'] =''; // MySQL 密碼 (only needed 留空就可以了)
9、查找 $cfg['Servers'][$i]['only_db'] = ''; // 你只有一個數據就設置一下,設置為你的數據庫名；如果你想架設服務器，那么建議留空
10、查找 $cfg['DefaultLang'] = ‘zh'; // 這里是選擇語言，zh代表簡體中文的意思
11、查找$cfg['blowfish_secret'] =''; // 如果認證方法設置為cookie，就需要設置短語密碼，設置為什么密碼，由您自己決定，這里不能留空，否則會在登錄 phpMyAdmin 時提示如下圖所示的錯誤。

12、設置完畢后保存，現在可以上傳到網絡空間上了，瀏覽http://網站域名/phpmyadmin/測試一下。（輸入數據庫的用戶名及密碼就可以了）

如果要安裝過程中出現：“phpMyAdmin - 錯誤缺少 mysqli 擴展。請檢查 PHP 配置。”錯誤。
解決方法如下：
①到phpmyadmin文件夾的/libraries/config.default.php文件中找：$cfg['Servers'][$i]['extension']='mysql';語句。
②如果有找到$cfg['Servers'][$i]['extension']='mysql';這句，就繼續查找下面這句$cfg['Servers'][$i]['extension']='mysqli'; 并把其的注釋去掉。
③如果沒有找到$cfg['Servers'][$i]['extension']='mysql';這句，就把$cfg['Servers'][$i]['extension']='mysqli';語句，改成$cfg['Servers'][$i]['extension']='mysql'; 語句。（即確保 " mysql " 值能生效）
