Linux软件包转换-deb与rpm互转_deb2rpm

前言：
Linux二进制软件包分为几大派系，其中deb与rpm为主流派。各个派系之间资源各有差异

1、工具安装

1.1、apt安装

apt系默认收录该软件，所以直接执行下面的安装命令即可

apt install -y alien
1

1.2、yum安装

由于yum系官方未收录该软件，所以需要先添加源再进行安装，命令步骤如下：

yum install -y epel-release
1

rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
1

rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm
1

然后更新源(可选)

yum update
1

最后是安装

yum install  -y alien
1

1.3、安装完成

执行下面的命令进行验证是否安装成功

[root@localhost ~]# alien -V
alien version 8.95
1
2

2、实践操作

2.1、语法解析

直接执行下面的命令即可调出帮助命令

alien
1

结果如下：

[root@localhost ~]# alien

从上面的信息可以看出，常用的两个参数为:

• -d #转为deb
• -r #转为rpm

2.2、rpm转deb

首先使用下面的命令下载一个rpm包

yum install  --downloadonly vsftpd  --downloaddir=/opt/
 cd /opt;ls
1

执行过程：

[root@localhost ~]# yum install  --downloadonly vsftpd  --downloaddir=/opt/

然后使用下面的命令进行转换

alien -d vsftpd-3.0.2-27.el7.x86_64.rpm

执行结果如下：

[root@localhost opt]# alien -d vsftpd-3.0.2-27.el7.x86_64.rpm

2.3、deb转rpm

使用下面的命令进行转换

[root@localhost opt]# rm -f vsftpd-3.0.2-27.el7.x86_64.rpm 
[root@localhost opt]# alien -r vsftpd_3.0.2-28_amd64.deb
