rpm包作为redhat、centos系列操作系统的包管理工具，让我们可以轻松通过yum install xxx.rpm命令安装某些软件包。本项目介绍文件打包方法，用于将任意文件按照描述文件的组织方式打包成rpm包。

如何使用
您可以从源码编译该项目或者从release包中下载！
源码编译安装
编译依赖：
- jdk8
- maven3
git clone https://github.com/xiaozhch5/rpm-package.git
cd rpm-package
mvn clean package编译完该代码可以在target中得到压缩文件rpm-package-1.0-bin.tar.gz，将该文件复制到centos7服务器中，并在centos服务器安装打包依赖：
yum install rpm-build -y解压文件：
代码语言：javascript复制tar zxvf rpm-package-1.0-bin.tar.gz得到 rpm-package-1.0-bin，
运行测试用例：
- 修改描述文件
vi rpm-package-1.0-bin/examples/example-1.json得到：
代码语言：javascript复制{
"rpmName": "test",
"rpmVersion": "1.0",
"rpmNeedarch": "x86_64",
"originalPath": "/root/rpm-package-1.0-bin/examples",
"targetRpmPath": "/root",
"dirMappings":
[
{
"from": "/var",
"to":"/usr/examples/var"
},
{
"from": "/usr",
"to":"/usr/examples/var"
},
{
"from": "/log",
"to":"/usr/examples/log"
}
],
"prepareScriptlet":
{
"script": "echo "Hello World""
},
"postinstallScriptlet":
{
"fileEncoding": "UTF-8",
"scriptFile": "/root/rpm-package-1.0-bin/examples/postinstall.sh"
}
}其中
- rpmName表示该rpm包的名称
- rpmVersion表示rpm包的版本
- rpmNeedarch为CPU架构。
- originalPath表示将该路径下的文件或者文件夹尽心打包（需要与dirMappings的from结合），注意dirMappings的第一层from – to， 表示该将/root/rpm-package-1.0-bin/examples/var进行打包，对应于rpm包中的/usr/examples/var路径。 /root/rpm-package-1.0-bin/examples需要修改为本机真实路径。
- targetRpmPath表示rpm最终的打包路径（存放xxx.rpm文件）
- prepareScriptlet表示在该rpm包被安装之前会执行的脚本。
- postinstallScriptlet表示在该rpm包被安装之后会执行的脚本。
- 修改完上述描述文件之后，即可执行测试用例：
cd rpm-package-1.0-bin && sh build-rpm.sh --mappingsFilePath /root/rpm-package-1.0-bin/examples/example-1.json执行完测试用例，即可看到对应rpm包
直接下载二进制文件使用
直接下载二进制文件可省略编译阶段，其他流程全部一样。
