一.常见LAMP应用

PhpMyAdmin
　　是一个以PHP为基础，以Web-Base方式架构在网站主机上的MySQL的数据库管理工具，让管理者可用Web接口管理MySQL数据库

WordPress
　　是一种使用PHP语言开发的博客平台，用户可以在支持PHP和MySQL数据库的服务器上架设属于自己的网站。也可把 WordPress当作一个内容管理系统（CMS）来使用
   WordPress后来成为了一个"生态系统"，它的作者也因此收入了数以千万美元的收入。WordPress本身也是开源的，围绕在WordPress背后形成了一个庞大的“生态圈”，有提供模板的，插件的，内容管理系统的（CMS）等等，我们可以去官网下载软件进行安装。 

PHPWind:
　　phpwind是杭州的一家公司，2003年发布了PHPWind的前身版本ofstar，并发展成为包含BBS、CMS、博客、SNS等一系列程序的通用型建站软件, 于2008年加入阿里巴巴集团

Crossday Discuz! Board（简称 Discuz!）
　　discuz是phpwind竞争对手，是一套通用的社区论坛软件系统。自2001年6月面世以来，是全球成熟度最高、覆盖率最大的论坛软件系统之一。2010年8月23日，与腾讯达成收购协议
　　其实discuz!就有门户站点的功能，国外也有drupal和xooms等等。这些都是开源的，因为我们都可以在网上下载下来安装测试，但是如果你想用这些软件进行营利的话，你可能就得向官方购买授权啦~

Phpbb：
　　是全球比较流行，国人用的比较少，外国人用的倒是不少，不过phpbb现在已经被汉化了，对中文的支持也不错。phpwind和discuz都是国人开发的，没错，不知道为什么自己就是相当的自豪，尽管我不是PHP程序员。phpbb是外国人开发的，在全球的影响力还是相当不错的哟。
　　外国还有一个叫"hpwind"也还不错，感兴趣的小伙伴也可以下载部署一下，我这里就不罗嗦了。

ECShop
　　是一款B2C独立网店系统，适合企业及个人快速构建个性化网上商店。系统是基于PHP语言及MYSQL数据库构架开发的跨平台开源程序。2006年6月，ECShop推出第一个版本1.0

二.布署phpMyadmin

1>.查看phpMyadmin所以来的php及MySQL版本(https://www.phpmyadmin.net/downloads/)

Summary     : PHP scripting language for creating dynamic web sites
URL         : http://www.php.net/
License     : PHP and Zend and BSD
Description : PHP is an HTML-embedded scripting language. PHP attempts to make it
            : easy for developers to write dynamically generated web pages. PHP also
            : offers built-in database integration for several commercial and
            : non-commercial database management systems, so writing a
            : database-enabled webpage with PHP is fairly simple. The most common
            : use of PHP coding is probably as a replacement for CGI scripts.
            :
            : The php package contains the module (often referred to as mod_php)
            : which adds support for the PHP language to Apache HTTP Server.

[root@node101.yinzhengjie.org.cn ~]# yum info php　　　　　　　　　　　　　　#CenOS7.6默认使用的是php5.4.16版本，如果不想编译安装php的话建议选择版本相对较久的PhpMyadmin

2>.咱们这里选择较久的版本安装phpadmin(https://www.phpmyadmin.net/files/),后面我会介绍使用编译安装最新版本

3>.安装phpMyAdmin所依赖的程序

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
 ... Success!

By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y
 ... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!
