用 dpkg 命令在 Debian 系的 Linux 系统中管理软件包
|
||
==================
|
||
|
||
[dpkg][7] 意即 Debian 包管理器（Debian PacKaGe manager）。dpkg 是一个可以安装、构建、删除及管理 Debian 软件包的命令行工具。dpkg 将 Aptitude（首选而更用户友好）作为执行所有操作的前端界面。
|
||
|
||
其它的一些工具如 dpkg-deb 和 dpkg-query 等也使用 dpkg 作为执行某些操作的前端。
|
||
|
||
现在大多数系统管理员使用 Apt、[Apt-Get][6] 及 Aptitude 等工具，不用费心就可以轻松地管理软件。
|
||
|
||
尽管如此，必要的时候还是需要用 dpkg 来安装某些软件。其它的一些在 Linux 系统上广泛使用的包管理工具还有 [yum][5]、[dnf][4]、[apt-get][3]、dpkg、[rpm][2]、[Zypper][1]、pacman、urpmi 等等。
|
||
|
||
现在，我要在装有 Ubuntu 15.10 的机器上用一些实例讲解最常用的 dpkg 命令。
|
||
|
||
### 1) dpkg 常见命令的语法及 dpkg 文件位置
|
||
|
||
下面是 dpkg 常见命令的语法及 dpkg 相关文件的位置，如果想深入了解，这些对你肯定大有益处。
|
||
|
||
```
|
||
### dpkg 命令的语法
|
||
$ dpkg -[command] [.deb package name]
|
||
|
||
$ dpkg -[command] [package name]
|
||
|
||
### dpkg 相关文件的位置
|
||
$ /var/lib/dpkg
|
||
|
||
### 这个文件包含了被 dpkg 命令（install、remove 等）所修改的包的信息
|
||
$ /var/lib/dpkg/status
|
||
|
||
### 这个文件包含了可用包的列表
|
||
$ /var/lib/dpkg/status
|
||
|
||
```
|
||
|
||
### 2) 安装/升级软件
|
||
|
||
在基于 Debian 的系统里，比如 Debian、Mint、Ubuntu 和 elementryOS，用以下命令来安装/升级 .deb 软件包。这里我要用 `atom-amd64.deb` 文件安装 Atom。要是已经安装了 Atom，就会升级它。要么就会安装一个新的 Atom。
|
||
|
||
```
|
||
### 安装或升级 dpkg 软件包
|
||
$ sudo dpkg -i atom-amd64.deb
|
||
Selecting previously unselected package atom.
|
||
(Reading database ... 426102 files and directories currently installed.)
|
||
Preparing to unpack atom-amd64.deb ...
|
||
Unpacking atom (1.5.3) over (1.5.3) ...
|
||
Setting up atom (1.5.3) ...
|
||
Processing triggers for gnome-menus (3.13.3-6ubuntu1) ...
|
||
Processing triggers for bamfdaemon (0.5.2~bzr0+15.10.20150627.1-0ubuntu1) ...
|
||
Rebuilding /usr/share/applications/bamf-2.index...
|
||
Processing triggers for desktop-file-utils (0.22-1ubuntu3) ...
|
||
Processing triggers for mime-support (3.58ubuntu1) ...
|
||
|
||
```
|
||
|
||
### 3) 从文件夹里安装软件
|
||
|
||
在基于 Debian 的系统里，用下列命令从目录中逐个安装软件。这会安装 `/opt/software` 目录下的所有以 .deb 为后缀的软件。
|
||
|
||
```
|
||
$ sudo dpkg -iR /opt/software
|
||
Selecting previously unselected package atom.
|
||
(Reading database ... 423303 files and directories currently installed.)
|
||
Preparing to unpack /opt/software/atom-amd64.deb ...
|
||
Unpacking atom (1.5.3) ...
|
||
Setting up atom (1.5.3) ...
|
||
Processing triggers for gnome-menus (3.13.3-6ubuntu1) ...
|
||
Processing triggers for bamfdaemon (0.5.2~bzr0+15.10.20150627.1-0ubuntu1) ...
|
||
Rebuilding /usr/share/applications/bamf-2.index...
|
||
Processing triggers for desktop-file-utils (0.22-1ubuntu3) ...
|
||
Processing triggers for mime-support (3.58ubuntu1) ...
|
||
```
|
||
|
||
### 4) 显示已安装软件列表
|
||
|
||
以下命令可以列出 Debian 系的系统中所有已安装的软件，同时会显示软件版本和描述信息。
|
||
|
||
```
