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:

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
Directory Contents of Directory
/usr/bin Client programs and scripts
/usr/sbin The mysqld server
/var/lib/mysql Log files, databases
/var/lib/mysql-files Value of secure_file_priv
/usr/share/info MySQL manual in Info format
/usr/share/man Unix manual pages
/usr/include/mysql Include (header) files
/usr/lib/mysql Libraries
/usr/share/mysql Miscellaneous support files, including error messages, character set files, sample configuration files, SQL for database installation
/usr/share/sql-bench Benchmarks
 
MySQL 5.7
Files or Resources Location
Client programs and scripts /usr/bin
mysqld server /usr/sbin
Configuration file /etc/my.cnf
Data directory /var/lib/mysql
Error log file For RHEL, Oracle Linux, CentOS or Fedora platforms: /var/log/mysqld.log
For SLES: /var/log/mysql/mysqld.log
Value of secure_file_priv /var/lib/mysql-files
System V init script For RHEL, Oracle Linux, CentOS or Fedora platforms: /etc/init.d/mysqld
For SLES: /etc/init.d/mysql
Systemd service For RHEL, Oracle Linux, CentOS or Fedora platforms: mysqld
For SLES: mysql
Pid file /var/run/mysql/mysqld.pid
Socket /var/lib/mysql/mysql.sock
Keyring directory /var/lib/mysql-keyring
Unix manual pages /usr/share/man
Include (header) files /usr/include/mysql
Libraries /usr/lib/mysql
Miscellaneous support files (for example, error messages, and character set files) /usr/share/mysql
 
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。
