昨天晚上在centos学习Samba配置共享文件服务器，还算顺利：二三个小时左右完成了SAMBA服务的配置，昨天根据头条文章依次执行和配置，只有一点点小错！

今天事情并不多，在学习shell脚本，就想能不能用shell脚本，一次性就把CentOS linux 的文件共享服务器完成呢？

shell脚本需要完成的实验需求：

网络拓扑结构图

shell脚本运行目标：

• 1、建立WORKGROUP工作组，建立Manage、Human、Salas帐号和访问密码；
• 2、建立拓扑图对应的之public、doc、soft共享文件夹、权限、访问；
• 3、自动完成smb.conf文件的修改，达到网络访问的目标；
• 4、自动运行smb服务，并加载到对应的启动项；
