如果想解壓*.src.rpm格式的包，可以執行rpm2cpio命令。

##  如果想解壓*.src.rpm格式的包，可以執行rpm2cpio命令。

    如下所示，有個*.src.rpm文件：
    [ root@localhost liusu]# ll
    total 1164
    -rw-r--r-- 1 root root 1188824 Nov 15 09:42 openstack-keystone-9.0.0-1.el7.src.rpm
   
    執行rpm2cpio命令來解壓：
    [ root@localhost liusu]# rpm2cpio openstack-keystone-9.0.0-1.el7.src.rpm |cpio -iv
    keystone-9.0.0.tar.gz
    keystone-dist.conf
    openstack-keystone-sample-data
    openstack-keystone.logrotate
    openstack-keystone.service
    openstack-keystone.spec
    openstack-keystone.sysctl
    2331 blocks
   
    如下所示，加壓後得文件列表：
    [ root@localhost liusu]# ll
    total 2352
    -rw-rw-r-- 1 root root 1181342 Nov 15 09:43 keystone-9.0.0.tar.gz
    -rw-rw-r-- 1 root root 263 Nov 15 09:43 keystone-dist.conf
    -rw-r--r-- 1 root root 1188824 Nov 15 09:42 openstack-keystone-9.0.0-1.el7.src.rpm
    -rw-rw-r-- 1 root root 96 Nov 15 09:43 openstack-keystone.logrotate
    -rwxrwxr-x 1 root root 53 Nov 15 09:43 openstack-keystone-sample-data
    -rw-rw-r-- 1 root root 242 Nov 15 09:43 openstack-keystone.service
    -rw-rw-r-- 1 root root 10122 Nov 15 09:43 openstack-keystone.spec
    -rw-rw-r-- 1 root root 201 Nov 15 09:43 openstack-keystone.sysctl
   
##  .tar.bz2
    套件名稱：bzip2。
    壓縮：
    [ jonny@linux ~ ]
    $ tar jcvf FileName.tar.bz2 DirName
    解壓縮：
    [ jonny@linux ~ ]
    $ tar jxvf FileName.tar.bz2
