总的来说,一般用户都是以命令行的方式来对MySQL数据库(和PHP搭配之最佳组合)进行使用。很多的用户在Windows环境中通常使用的是图形用户界面(GUI)去操作与管理数据库,对命令行方式可能不习惯。 而很多新手更是觉得MySQL(和PHP搭配之最佳组合)不容易掌握。

总的来说,一般用户都是以命令行的方式来对MySQL数据库(和PHP搭配之最佳组合)进行使用。很多的用户在Windows环境中通常使用的是图形用户界面(GUI)去操作与管理数据库,对命令行方式可能不习惯。

而很多新手更是觉得MySQL(和PHP搭配之最佳组合)不容易掌握。

为了方便用户对MySQL(和PHP搭配之最佳组合)数据库进行管理,实际上早就已经有一些图形化用户管理的项目在进行中,它们是MySQ数据库L(和PHP搭配之最佳组合) Control Center(MySQL(和PHP搭配之最佳组合)CC)、MySQL(和PHP搭配之最佳组合)GUI和phpMyAdmin。此外,使用Red Hat自带的OpenOffice也可以完成对MySQL(和PHP搭配之最佳组合)的图形化管理。

安装MySQL(和PHP搭配之最佳组合)

在安装、设置和应用图形化管理工具之前,首先要安装好MySQL(和PHP搭配之最佳组合)服务器。使用以下命令查看本机是否安装了MySQL(和PHP搭配之最佳组合):

<ol class="dp-xml">
<li class="alt"><span><span># rpm -qa | grep MySQL(和PHP搭配之最佳组合)  </span></span></li>
<li><span>MySQL(和PHP搭配之最佳组合)-server-3.23.54a-11  </span></li>
<li class="alt"><span>MySQL(和PHP搭配之最佳组合)-3.23.54a-11 </span></li>
</ol>
Copy after login

本文所有例子均在Red Hat 9.0中实现。在Red Hat 9.0中,可以通过“软件包管理”程序来直接安装MySQL(和PHP搭配之最佳组合)。具体方法是先在“添加或删除软件包”界面选中“SQL数据库服务器”,并在细节中选中“MySQL数据库(和PHP搭配之最佳组合)-server - MySQL(和PHP搭配之最佳组合)服务器和相关的文件”,然后插入第二张光盘,选择更新即可。

也可以通过直接从光盘上使用rpm命令进行安装。因为MySQL(和PHP搭配之最佳组合)服务器需要Perl语言的支持才能正常运行,所以在采用后一种安装方法时,安装MySQL(和PHP搭配之最佳组合)前需要先安装Perl语言及相关软件包。

安装完成后,使用以下命令启动MySQL(和PHP搭配之最佳组合)服务器:

<ol class="dp-xml"><li class="alt"><span><span>#service MySQL(和PHP搭配之最佳组合)d start </span></span></li></ol>
Copy after login

MySQL(和PHP搭配之最佳组合)在安装完成后,预定义了一个超级用户root,口令为空。任何用户均可以从MySQL(和PHP搭配之最佳组合)服务器本地使用该用户连接MySQL(和PHP搭配之最佳组合)数据库进行操作。显然这非常不安全,所以MySQL数据库(和PHP搭配之最佳组合)启动之后,应该立即设置root密码。设置方法如下:

<ol class="dp-xml"><li class="alt"><span><span>#MySQL(和PHP搭配之最佳组合)admin password 'ylgui' </span></span></li></ol>
Copy after login

这样就设置了一个新的密码:ylgui。

MySQL(和PHP搭配之最佳组合)服务器是否已经正常运行?可以通过启用客户端程序MySQL(和PHP搭配之最佳组合)进行查看。这里要使用到上面设置的密码:

<ol class="dp-xml">
<li class="alt"><span><span># MySQL(和PHP搭配之最佳组合) -u root -pylgui  </span></span></li>
<li><span>Welcome to the MySQL(和PHP搭配之最佳组合) monitor. Commands end with ; or \g.  </span></li>
<li class="alt"><span>Your MySQL(和PHP搭配之最佳组合) connection id is 6 to server version: 3.23.54  </span></li>
<li><span>Type 'help;' or '\h' for help. Type '\c' to clear the buffer. </span></li>
</ol>
Copy after login

注意,参数p与密码之间没有空格。屏幕会显示目前都有哪些数据库:

<ol class="dp-xml"><li class="alt"><span><span>MySQL(和PHP搭配之最佳组合)</span><span class="tag">></span><span> show databases;<br>+----------+| Database |+----------+| MySQL(和PHP搭配之最佳组合) <br>|| test |+----------+2 rows in set (0.01 sec) </span></span></li></ol>
Copy after login

可以看到MySQL(和PHP搭配之最佳组合)数据库服务器里有两个数据库,分别是MySQL(和PHP搭配之最佳组合)和test。这表明该数据库服务器已经正确安装,并已经正常启动。

下面就分别看看四种MySQ数据库L(和PHP搭配之最佳组合) GUI解决方案的安装、设置和使用情况。
