一般情况下打包文件时，如果直接打包软连接会导致打包失败，即没有将要打包的内容打包进去，这里提供tar打包参数-h

[root@localhost ~]# ll /etc/rc.local

lrwxrwxrwx. 1 root root 13 Nov 24 00:45 /etc/rc.local -> rc.d/rc.local

[root@localhost ~]# tar czf tar.gz /etc/rc.local

tar: Removing leading `/' from member names

[root@localhost ~]# ll

[root@localhost ~]# sz tar.gz

rz

Starting zmodem transfer.  Press Ctrl+C to cancel.

100%     117 bytes  117 bytes/s 00:00:01       0 Errors

[root@localhost ~]#

发现打包结果并没有将/etc/rc.local下的内容打包进来

所以这里用-h参数

[root@localhost ~]# tar czfh rc.local.tar.gz /etc/rc.local

tar: Removing leading `/' from member names

[root@localhost ~]# ll

至此，用tar打包软连接实际目录下内容操作成功
