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:

 

  Directory

Contents of Directory

/etc

一些配置文件的目录,例如/etc/init.d/mysql

 

/usr/bin

一些可执行文件

/usr/lib

一些程序使用的动态函数库

/usr/share/doc

一些基本的软件使用手册与帮助文档

/usr/share/man

一些man page文件

 

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:

[root@DB-Server ~]# rpm -qc MySQL-server-advanced-5.6.20-1.rhel5

 

/etc/logrotate.d/mysql

 

/etc/my.cnf

 

[root@DB-Server ~]# 

 

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

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。
