在 CentOS/RHEL 上查找 yum 安裝的软件的位置
|
||
======
|
||
|
||
**我已经在 CentOS/RHEL 上[安装了 htop][1] 。现在想知道软件被安装在哪个位置。有没有简单的方法能找到 yum 软件包安装的目录呢？**
|
||
|
||
[yum 命令][2] 是可交互的、基于 rpm 的 CentOS/RHEL 的开源软件包管理工具。它会帮助你自动地完成以下操作：
|
||
|
||
1. 核心系统文件更新
|
||
2. 软件包更新
|
||
3. 安装新的软件包
|
||
4. 删除旧的软件包
|
||
5. 查找已安装和可用的软件包
|
||
|
||
和 `yum` 相似的软件包管理工具有： [apt-get 命令][3] 和 [apt 命令][4]。
|
||
|
||
### yum 安装软件包的位置
|
||
|
||
处于演示的目的，我们以下列命令安装 `htop`：
|
||
|
||
```
|
||
# yum install htop
|
||
```
|
||
|
||
要列出名为 htop 的 yum 软件包安装的文件，运行下列 `rpm` 命令：
|
||
|
||
```
|
||
# rpm -q {packageNameHere}
|
||
# rpm -ql htop
|
||
```
|
||
|
||
示例输出：
|
||
|
||
```
|
||
/usr/bin/htop
|
||
/usr/share/doc/htop-2.0.2
|
||
/usr/share/doc/htop-2.0.2/AUTHORS
|
||
/usr/share/doc/htop-2.0.2/COPYING
|
||
/usr/share/doc/htop-2.0.2/ChangeLog
|
||
/usr/share/doc/htop-2.0.2/README
|
||
/usr/share/man/man1/htop.1.gz
|
||
/usr/share/pixmaps/htop.png
|
||
```
|
||
|
||
### 如何使用 repoquery 命令查看由 yum 软件包安装的文件位置
|
||
|
||
首先使用 [yum 命令][2] 安装 yum-utils 软件包：
|
||
|
||
```
|
||
# yum install yum-utils
|
||
```
|
||
|
||
示例输出：
|
||
|
||
```

|
||
```
|
||
|
||
### 如何列出通过 yum 安装的命令？
|
||
|
||
现在可以使用 `repoquery` 命令：
|
||
|
||
```
|
||
# repoquery --list htop
|
||
```
|
||
|
||
或者：
|
||
|
||
```
|
||
# repoquery -l htop
|
||
```
|
||
|
||
示例输出：
|
||
|
||
[![yum where is package installed][5]][5]
|
||
|
||
*使用 repoquery 命令确定 yum 包安装的路径*
|
||
|
||
你也可以使用 `type` 命令或者 `command` 命令查找指定二进制文件的位置，例如 `httpd` 或者 `htop` ：
|
||
|
||
```
|
||
$ type -a httpd
|
||
$ type -a htop
|
||
$ command -V htop
|
||
```
