phpmyadmin Installation tutorial

非常适合对数据库操作命令不熟悉的数据库管理者,下面我就说下怎么安装该工具:

1.先到网上下载phpmyadmin,再解压到可以访问的web目录下(如果是虚拟空间,可以解压后通过ftp等上传到web目录下),当然您可以修改解压后该文件的名称。

2.配置config文件
  打开libraries下的config.default.php文件,依次找到下面各项,按照说明配置即可:
A.访问网址 
引用:
$cfg['PmaAbsoluteUri'] = '';这里填写phpmyadmin的访问网址

B.mysql主机信息 
引用:
$cfg['Servers'][$i]['host'] = 'localhost'; // MySQL hostname or IP address
填写localhost或mysql所在服务器的ip地址,如果mysql和该phpmyadmin在同一服务器,则按默认localhost
$cfg['Servers'][$i]['port'] = ''; // MySQL port - leave blank for default port
mysql端口,如果是默认3306,保留为空即可

C.mysql用户名和密码 
引用:
$cfg['Servers'][$i]['user'] = 'root'; // MySQL user 访问phpmyadmin使用的mysql用户名
fg['Servers'][$i]['password'] = ''; // MySQL password (only needed对应上述mysql用户名的密码
D.认证方法 
引用:
$cfg['Servers'][$i]['auth_type'] = 'cookie';
在此有四种模式可供选择,cookie,http,HTTP,config
   config方式即输入phpmyadmin的访问网址即可直接进入,无需输入用户名和密码,是不安全的,不推荐使用。
   当该项设置为cookie,http或HTTP时,登录phpmyadmin需要数据用户名和密码进行验证,,具体如下:
   PHP安装模式为Apache,可以使用http和cookie;
   PHP安装模式为CGI,可以使用cookie

E.短语密码(blowfish_secret)的设置 
引用:
$cfg['blowfish_secret'] = '';
如果认证方法设置为cookie,就需要设置短语密码,置于设置为什么密码,由您自己决定  ,但是不能留空,否则会在登录phpmyadmin时提示错误
  好了,到此为止,您已经成功安装了phpmyadmin,简单吧 ,赶快登录体验下吧

说明:
该文档说明的只是安装phpmyadmin的基本配置,关于config.default.php文件中各个配置参数的详细说明可以 

 phpMyAdmin 就是一种 MySQL 数据库的管理工具,安装该工具后,即可以通过 web 形式直接管理 MySQL 数据,而不需要通过执行系统命令来管理,非常适合对数据库操作命令不熟悉的数据库管理者,下面详细说明该工具的安装方法。
一、下载
1、先到官方站点下载phpMyAdmin 安装包:http://www.phpmyadmin.net/ (安装包含各种语言all-languages)
2、再解压到 web 可以访问的目录下,如果是虚拟空间,可以解压后通过 ftp 工具上传到 web 目录下,同时您可以修改解压后该文件的名称(你可以自定义目录名称)。

二、配置
3、打开 /libraries/config.default.php文件(旧版本是根目录下的config.inc.php文件),用写字板(不要用记事本,这是UTF8编码)进行编辑,按照说明配置即可。
4、查找 $cfg['PmaAbsoluteUri']=‘';   // 修改为你将上传到空间的phpMyAdmin的网址
如:$cfg['PmaAbsoluteUri'] =‘http:   // 网站域名/phpmyadmin/'; 
5、查找 $cfg['Servers'][$i]['host'] =‘localhost';    // 通常用默认,也有例外,可以不用修改
6、查找 $cfg['Servers'][$i]['auth_type'] =‘config';   // 在自己的机子里调试用config;如果在网络上的空间用cookie.
在此有四种模式可供选择:cookie,http,HTTP,config
① config 方式即输入phpMyAdmin 的访问网址即可直接进入,无需输入用户名和密码,是不安全的,不推荐使用。
② 设置cookie,http,HTTP方式,登录 phpMyAdmin 需要数据用户名和密码进行验证。
具体如下:PHP 安装模式为 Apache,可以使用 http 和 cookie;PHP 安装模式为 CGI,可以使用 cookie。
7、查找 $cfg['Servers'][$i]['user'] = ‘root';   // MySQL用户名
8、查找 $cfg['Servers'][$i]['password'] ='';   // MySQL 密码 (only needed 留空就可以了)
9、查找 $cfg['Servers'][$i]['only_db'] = '';   // 你只有一个数据就设置一下,设置为你的数据库名;如果你想架设服务器,那么建议留空
10、查找 $cfg['DefaultLang'] = ‘zh';   // 这里是选择语言,zh代表简体中文的意思
11、查找$cfg['blowfish_secret'] ='';   // 如果认证方法设置为cookie,就需要设置短语密码,设置为什么密码,由您自己决定,这里不能留空,否则会在登录 phpMyAdmin 时提示如下图所示的错误。

12、设置完毕后保存,现在可以上传到网络空间上了,浏览http://网站域名/phpmyadmin/测试一下。(输入数据库的用户名及密码就可以了)

如果要安装过程中出现:“phpMyAdmin - 错误 缺少 mysqli 扩展。请检查 PHP 配置。”错误。
解决方法如下:
①到phpmyadmin文件夹的\libraries\config.default.php文件中找:$cfg['Servers'][$i]['extension']='mysql';语句。
②如果有找到$cfg['Servers'][$i]['extension']='mysql';这句,就继续查找下面这句$cfg['Servers'][$i]['extension']='mysqli'; 并把其的注释去掉。
③如果没有找到$cfg['Servers'][$i]['extension']='mysql';这句,就把$cfg['Servers'][$i]['extension']='mysqli';语句,改成$cfg['Servers'][$i]['extension']='mysql'; 语句。(即确保 " mysql " 值能生效)
