## README

## 预备条件
```
sudo apt-get install -y gcc dpkg-dev gpg
```
使用以上命令安装所需工具，以hello world为例下面制作一个deb包

## 第一步 准备hello word源码
```
fromdtor@april:~/hello-world$ tree
.
├── bin
└── src
    └── hello.c

2 directories, 1 file
fromdtor@april:~/hello-world$ cat src/hello.c
#include <stdio.h>
int main() {
    printf("hello packaged world\n");
    return 0;
}
fromdtor@april:~/hello-world$
```
示例目录中有两个目录，src下有一个c源文件,编译并运行：
```
fromdtor@april:~/hello-world$ gcc -o bin/hello-world src/hello.c
fromdtor@april:~/hello-world$ tree
.
├── bin
│   └── hello-world
└── src
    └── hello.c

2 directories, 2 files
fromdtor@april:~/hello-world$ ./bin/hello-world
hello packaged world
fromdtor@april:~/hello-world$
```

## 第二步 创建deb包
先创建一个以下命名格式的目录
```
<package-name>_<version>-<release-number>_<architecture>
```
```
fromdtor@april:~/hello-world$ mkdir hello-world_0.0.1-1_amd64
fromdtor@april:~/hello-world$ mkdir -p hello-world_0.0.1-1_amd64/usr/
fromdtor@april:~/hello-world$
fromdtor@april:~/hello-world$ mv bin hello-world_0.0.1-1_amd64/usr/
fromdtor@april:~/hello-world$ tree
.
├── hello-world_0.0.1-1_amd64
│   └── usr
│       └── bin
│           └── hello-world
└── src
    └── hello.c

4 directories, 2 files
```
添加文件hello-world_0.0.1-1_amd64/DEBIAN/control，内容如下
```
fromdtor@april:~/hello-world$ tree
.
├── hello-world_0.0.1-1_amd64
│   ├── DEBIAN
│   │   └── control
│   └── usr
│       └── bin
│           └── hello-world
└── src
    └── hello.c

5 directories, 3 files
fromdtor@april:~/hello-world$ cat hello-world_0.0.1-1_amd64/DEBIAN/control
Package: hello-world
Version: 0.0.1
Maintainer: example <example@example.com>
Depends: libc6
Architecture: amd64
Homepage: http://example.com
Description: A program that prints hello
fromdtor@april:~/hello-world$
```
然后运行以下命令
> dpkg --build hello-world_0.0.1-1_amd64
现在目录中多了一个文件hello-world_0.0.1-1_amd64.deb
```
fromdtor@april:~/hello-world$ dpkg --build hello-world_0.0.1-1_amd64
dpkg-deb: building package 'hello-world' in 'hello-world_0.0.1-1_amd64.deb'.
fromdtor@april:~/hello-world$ ls
hello-world_0.0.1-1_amd64  hello-world_0.0.1-1_amd64.deb  src
fromdtor@april:~/hello-world$
```
检查一下包含的内容
```
fromdtor@april:~/hello-world$ dpkg-deb --info hello-world_0.0.1-1_amd64.deb
 new Debian package, version 2.0.
 size 2744 bytes: control archive=340 bytes.
     183 bytes,     7 lines      control
 Package: hello-world
 Version: 0.0.1
 Maintainer: example <example@example.com>
 Depends: libc6
 Architecture: amd64
 Homepage: http://example.com
 Description: A program that prints hello
fromdtor@april:~/hello-world$ dpkg-deb --contents hello-world_0.0.1-1_amd64.deb
drwxrwxr-x fromdtor/fromdtor 0 2022-08-31 14:19 ./
drwxrwxr-x fromdtor/fromdtor 0 2022-08-31 14:16 ./usr/
drwxrwxr-x fromdtor/fromdtor 0 2022-08-31 14:12 ./usr/bin/
-rwxrwxr-x fromdtor/fromdtor 8304 2022-08-31 14:12 ./usr/bin/hello-world
fromdtor@april:~/hello-world$
```
使用以下命令也可以
> less hello-world_0.0.1-1_amd64.deb

#### 第三步 安装测试
```
安装之前
fromdtor@april:~/hello-world$ which hello-world

指定文件安装
fromdtor@april:~/hello-world$ sudo apt-get install -f ~/example/hello-world_0.0.1-1_amd64.deb

Note, selecting 'hello-world' instead of '/home/fromdtor/example/hello-world_0.0.1-1_amd64.deb'
The following packages were automatically installed and are no longer required:
  alien at bc cups-bsd cups-client debhelper debugedit dh-autoreconf dh-strip-nondeterminism golang-1.10 golang-1.10-doc golang-1.10-go
  golang-1.10-race-detector-runtime golang-1.10-src golang-race-detector-runtime golang-src intltool-debian libarchive-cpio-perl libarchive-zip-perl

  librpmio8 librpmsign8 libsys-hostname-long-perl libyaml-0-2 lsb-security pax pkg-config po-debconf rpm rpm-common rpm2cpio systemtap-common
  systemtap-runtime
Use 'sudo apt autoremove' to remove them.
The following NEW packages will be installed:
  hello-world
0 upgraded, 1 newly installed, 0 to remove and 9 not upgraded.
Need to get 0 B/2,740 B of archives.
After this operation, 0 B of additional disk space will be used.

安装之后
fromdtor@april:~/hello-world$ which hello-world
/usr/bin/hello-world

验证运行
fromdtor@april:~/hello-world$ hello-world
hello packaged world
fromdtor@april:~/hello-world$
```

#### 第四步 卸载
```
sudo apt-get remove hello-world
```

后续关于怎么托管自己的deb包的详情可以参考这里
[Creating and hosting your own deb packages and apt repo](https://earthly.dev/blog/creating-and-hosting-your-own-deb-packages-and-apt-repo/)
这里就先不管了

#### 恢复apt环境
1.删除锁文件
> sudo rm /var/lib/apt/lists/lock
2.更新索引
> sudo apt-get update
