scripting - 创建一个 shell 脚本来安装更新

Question

好的，基于一些额外的研究和下面的 yum 答案，这就是我希望我的脚本执行的操作：

1. 提取更新
2. 按特定顺序安装更新
3. 等待几秒钟，让每个部分的 yum 更新完成
4. 重置根帐户密码（我如何通过脚本硬编码或设置？）
5. 重置 ssh 帐户密码（如何通过脚本进行硬编码或设置？）
6. 清除历史
7. 删除文件

8. 提示重新启动

   #!/bin/sh
   # Run as root
   
   # This extracts the tar copied to the server
   tar -xf updates
   sleep 5
   tar -xf app
   sleep 2
   
   # This moves to the February updates and install it.
   cd /updates/feb
   yum -y update *.rpm
   sleep 5
   # This moves to the March updates and install it.
   cd /updates/mar
   yum -y update *.rpm
   sleep 5
   # This moves to the April updates and install it.
   cd /updates/apr
   yum -y update *.rpm
   sleep 5
   # This moves to the May updates and install it.
   cd /updates/may
   yum -y update *.rpm
   sleep 5
   # This moves to the June updates and install it.
   cd /updates/june
   yum -y update *.rpm
   sleep 5
   # This moves to the August updates and install it.
   cd /updates/aug
   yum -y update *.rpm
   sleep 5
   # This moves to the September updates and install it.
   cd /updates/sep
   yum -y update *.rpm
   sleep 5
   # This moves to the APP dependencies and install it.
   cd /updates/app
   yum -y install *.rpm
   sleep 5
   # This resets the root password
   passwd root
   # This resets the ssh account password
   passwd ssh_user
   # This removes the files from the home directory
   cd /home/user
   rm -rf /updates
   wait 5
   # This clears the history and screen
   history -c
   clear
   # This reboots the server with a y/n prompt
   reboot
   

为更新而编辑并为成为菜鸟而道歉！

像这样添加-y（告诉 yum 假设“是”的答案）：

yum -y update *.rpm
