使用rpmbuild制作rpm包
这里以制作cmake-3.15.5为例，首先保证环境中安装有rpmbuild，其次下载cmake-3.15.5.tar.gz源代码包。
1. 在/root目录下生成rpmbuild目录
mkdir -p ~/rpmbuild/BUILD ~/rpmbuild/RPMS ~/rpmbuild/BUILDROOT ~/rpmbuild/SRPMS ~/rpmbuild/SOURCES ~/rpmbuild/SPECS
2. vi ~/rpmbuild/SPECS/cmake.spec 自动生成spec模板文件，并填写相关字段，现给出我的spec文件

3. 执行 rpmbuild -ba ~/rpmbuild/SPECS/cmake.spec
接下来是比较长的编译和安装过程，执行成功的界面如下：
以 exit 0 退出表示没有出错，然后在~/rpmbuild/RPMS/目录下可以看到形成了x86_64目录，该目录下有cmake-3.15.5-1.x86_64.rpm安装包：
在~/rpmbuild/SRPMS/目录下形成了cmake-3.15.5-1.src.rpm安装包：
到此，由源代码包制作rpm包的流程结束。
4. rpm -ivh ~/rpmbuild/RPM/x86_64/cmake-3.15.5-1.x86_64.rpm安装生成的rpm包：
以上表示安装成功。
5. 解析rpm包
rpm –qpl *.rpm # 列出rpm包包含的内容
rpm2cpio *.rpm | cpio –div # 解压rpm包
