Linux如何查看YUM的安装目录

Linux下如何查看使用YUM安装过的包的安装路径呢？ 在搞清楚这个问题前，我们先来了解一下YUM。 YUM（全称为 Yellow dog Updater, Modified）是一个在Fedora和RedHat以及CentOS中的Shell前端软件包管理器。基于RPM包管理，能够从指定的服务器自动下载RPM包并且安装，可以自动处理依赖性关系，并且一次安装所有依赖的软件包，避免了手动安装的麻烦(寻找资源、下载；放到指定目录安装；处理依赖关系并下载依赖关系的包进行安装)。所以用yum安装，实质上是用RPM安装，所以RPM查询信息的指令都可用。

如果使用RPM安装了一些包，一般来说，RPM默认安装路径如下：

<table style="margin-left:.35pt;width:556px;"> 
 <tbody> 
 <tr> 
 <td style="border-color:#8eaadb;"> &nbsp;&nbsp;Directory </td> 
 <td> Contents of Directory </td> 
 </tr> 
 <tr> 
 <td> /etc </td> 
 <td> 一些配置文件的目录，例如/etc/init.d/mysql &nbsp; </td> 
 </tr> 
 <tr> 
 <td style="vertical-align:top;"> /usr/bin </td> 
 <td style="vertical-align:top;"> 一些可执行文件 </td> 
 </tr> 
 <tr> 
 <td> /usr/lib </td> 
 <td> 一些程序使用的动态函数库 </td> 
 </tr> 
 <tr> 
 <td style="vertical-align:top;"> /usr/share/doc </td> 
 <td style="vertical-align:top;"> 一些基本的软件使用手册与帮助文档 </td> 
 </tr> 
 <tr> 
 <td> /usr/share/man </td> 
 <td> 一些man page文件 </td> 
 </tr> 
 </tbody> 
</table>

以MySQL的安装为例，我们使用RPM方式安装了MySQL的两个包，其实rpm有两个参数-l和-c可以帮助我们查看具体的安装路径。

\-l 显示软件包中的文件列表

\-c 显示配置文件列表

那么我们可以使用“rpm -ql  包名”来查看具体的安装路径。如下所示：

在MySQL的官方文档，你可以看到RPM包所在的安装目录。我们使用rpm -ql 对比验证了一下，基本都OK，但是很奇怪的是，在上面这个版本中，我没有找到/etc/my.cnf，而是/usr/my.cnf

MySQL 5.6

MySQL 5.7

另外一台测试服务器，使用yum安装了mysql-community-server-5.7.18，测试验证发现又是正常。 暂时不清楚这个细节问题。
