centos7使用rpmbuild制作RPM包

前言
    所有操作在root权限下执行
   
    一.将之前我们制作tarball软件包复制到/root/rpmbuild/SOURCES上面并打包
      复制
      cp -r /usr/local/src/sort-average /root/rpmbuild/SOURCES
      进入/root/rpmbuild/SOURCES目录
      cd /root/rpmbuild/SOURCES
      改目录名
      mv sort-average sort-average-0.1
      打包
      tar -zcvf sort-average-0.1-1.tar.gz sort-average-0.1
  
    二.在/root/rpmbuild/SPECS目录编写sort-average.spec文件
      Summary:        sort 10 integers or average 5 integers
      Name:           sort-average
      Version:        0.1
      Release:        1
      License:        GPL
      Group:          jison`s home
      Source:         sort-average-0.1-1.tar.gz
      Packager:       jison
      BuildRoot:      /root/rpmbuild

      %description
      This package will let you sort 10 integers or average 5 integers

      %prep
      %setup -q

      %build
      make

      %install
      mkdir -p %{buildroot}/usr/local/bin
      cp /root/rpmbuild/BUILD/sort-average-0.1/sort-average %{buildroot}/usr/local/bin
      make install RPM_INSTALL_ROOT=%{buildroot}

      %files
      /usr/local/bin/sort-average
    三.根据sort-average.spec文件生成RPM包
      rpmbuild -ba sort-average.spec
  -ba 编译并同时生成RPM与SRPM文件
  -bb 仅编译成RPM文件
      然后就可以在/root/rpmbuild/RPMS/x86_64文件夹看到打包好的RPM包了
      cd /root/rpmbuild/RPMS/x86_64
      ls
      结果为
sort-average-0.1-1.x86_64.rpm
sort-average-debuginfo-0.1-1.x86_64.rpm
    四.删除打包过程安装的sort-average命令并重新用打包好的sort-average-0.1-1.x86_64.rpm包安装sort-average命令
      卸载tarball方法安装的sort-average命令
      rm -f /usr/local/bin/sort-average
      安装 sort-average-0.1-1.x86_64.rpm包
      cd /root/rpmbuild/RPMS/x86_64
      rpm -ivh sort-average-0.1-1.x86_64.rpm
    五.测试安装好的sort-average命令
      sort-average
      Please input 's' or 'a or 'q':a
      Please input 5 integers to average:
      1 2 3 4 5
      average:
      3
      Please input 's' or 'a or 'q':s
      Please input 10 integers to sort:
      5 6 4 3 2 1 54 6 3 4
      after sort:
      1 2 3 3 4 4 5 6 6 54
      Please input 's' or 'a or 'q':q
      exit...
    六.卸载sort-average命令
      rpm -e sort-average-0.1-1.x86_64.rpm
