项目打包rpm包（rpmbuild）

这里以python项目为例，通过rpmbuild工具打包成rpm包，并进行安装验证

rpmbuild打包 rpm流程

• 构建rpmbuild打包目录

• rpmbuild 默认变量配置文件

• 将我们的python项目和依赖包压缩成xx.tar.gz格式，并copy到SOURCE目录

我们这里以datalake-demo-2.0项目为例，将其移到/root/rpmbuild/SOURCE即可

•  编写rpmbuild核心 spec 文件【datalake.spec】

        spec里面很多字段网上都有说明，这里只介绍几个关键参数

• rpmbuild  spec 文件示例

• rpmbuild spec参数说明 

•  开始rpmbuild rpd 【rpmbuild -ba datalake.spec】

• 查看rpm包【/root/rpmbuild/RPMS/x86_64】

• 尝试安装rpm包 【rpm -ivh datalake-demo-2.0-1.el7.x86_64.rpm】

 可以看到连同我们的python项目依赖包都安装好了 

• 卸载包 【rpm -e atalake-demo-2.0-1.el7.x86_64】 

 rpmbuild rpm包完成~

补充：

        在使用rpmbuild构建rpm包时，往往能够自动打出debuginfo包。如果不想要，可以echo "%debug_package %{nil}" >> ~/.rpmmacros 如果不想拆分出debuginfo包，让binary包里就是带调试符号的，可以在spec文件头加上%global debug_package %{nil}

        如果想打出debuginfo包，而默认却打不出来，可以检查机器是否安装了redhat-rpm-config包，如果没有，就会因为缺少brp-compress工具而打不出debuginfo包
