firefox-52 套件實例

  1. 緣由：firefox v45 某些網頁無法瀏覽。
  2. 下載 SRPM 套件 
    [dywang@dyw219 ~]$ cd rpmbuild
[dywang@dyw219 rpmbuild]$ wget http://vault.centos.org/centos/6.9/updates/\
Source/SPackages/firefox-52.6.0-1.el6.centos.src.rpm
  3. 安裝 SRPM 套件 
    [dywang@dyw219 rpmbuild]$ rpm -ivh firefox-52.6.0-1.el6.centos.src.rpm 
warning: firefox-52.6.0-1.el6.centos.src.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY
   1:firefox                ########################################### [100%]
  4. 查看安裝的所有檔案。 
    [dywang@dyw219 SOURCES]$ rpm -qpl ../firefox-52.6.0-1.el6.centos.src.rpm

  5. 查看程式主要的打包壓縮檔。 
    [dywang@dyw219 SOURCES]$ ls firefox-52.6.0esr.source.tar.xz 
firefox-52.6.0esr.source.tar.xz
  6. 解壓縮原始碼 tarball，產生 firefox-45.1.0esr 目錄，存放原始碼。 
    [dywang@dyw219 SOURCES]$ tar xJvf firefox-52.6.0esr.source.tar.xz
  7. 查看 firefox-45.1.0esr 目錄內的檔案。 
    [dywang@dyw219 SOURCES]$ ls firefox-52.6.0esr

  8. 進入暫存目錄 tmp，解開原始 src.rpm，方便做修改的比對。 
    [dywang@dyw219 SOURCES]$ cd ../tmp/
[dywang@dyw219 tmp]$ rm ./* -rf

  9. 暫存目錄下解開 firefox-52.6.0esr.source.tar.xz。 
    [dywang@dyw219 tmp]$ tar Jxvf firefox-52.6.0esr.source.tar.xz
  10. 修改 RPM spec 規格檔，版本加入 dyw。
