# 做盘步骤 #

## 所准备的工具和镜像： ##
  mkiso-4.2  
  rocky4.2.32-sqlproxy-2017-06-09.iso  
  rocky6.0.42.41-x86_64-security-20170815.iso  

## 修改光盘环境 ##

> 在root用户下进行操作

1. 挂载rocky4.2.32-sqlproxy-2017-06-09.iso  

  命令：  

```
	mount rocky4.2.32-sqlproxy-2017-06-09.iso /mnt -oloop  

```

2. 将/mnt 下的所有文件复制到电脑的cd目录里  

  命令：

```
	cp /mnt/. /home/lcliang/cd -R  

```

3. 挂载rocky6.0.42.41-x86_64-security-20170815.iso  

  命令：

```
	mount rocky6.0.42.41-x86_64-security-20170815.iso /home/lcliang/ce -oloop  

```

4. 把所要升级的内核修改文件复制到对应的目录下  

>   所需要修改的文件(lib/modules,boot/isolinux)

  命令：

```

   rm /home/lcliang/cd/lib/modules -r  

   cp /home/lcliang/ce/lib/modules /home/lcliang/cd/lib/ -R  

   rm /home/lcliang/cd/boot/isolinux/initrd.img-2.6.32.41-Rocky4.2-x86_64

   cp /home/lcliang/ce/boot/isolinux/initrd.img-2.6.32.41-Rocky4.2-x86_64 /home/lcliang/cd/boot/isolinux/  

   rm /home/lcliang/ce/boot/isolinux/vmlinuz-2.6.32.41-Rocky4.2-x86_64
   
   cp /home/lcliang/ce/boot/isolinux/vmlinuz-2.6.32.41-Rocky4.2-x86_64 /home/lcliang/cd/boot/isolinux/  

```

> 注意：要使修改的光盘的文件名称与之相对应。


## 修改光盘环境目录中的Rocky里的modules和kernel的的相关文件（相当于修改安装后的系统的内核和驱动模块） ##

1. 在虚拟机安装rocky6.0.42.41-x86_64-security-20170815.iso系统

2. 将所要升级的内核修改文件复制到对应的目录下(以下的scp命令都是个在6.0.42.41系统中执行)

> 所需要修改的文件（Rocky/modules,Rocky/kernel）

  命令：  

```

   rm /home/lcliang/cd/Rocky/modules -r

   scp -r /lib/modules/* lcliang@172.16.0.67:/home/lcliang/cd/Rocky/modules  

   rm build source 删除cd/Rocky/modules/2.6.32.41-Rocky4.2-x86_64目录下的build source  

   rm /home/lcliang/cd/Rocky/kernels/initrd.img-2.6.32.41-Rocky4.2-x86_64

   scp /boot/initrd.img-2.6.32.41-Rocky4.2-x86_64 lcliang@172.16.0.67:/home/lcliang/cd/Rocky/kernels  

   rm /home/lcliang/cd/Rocky/kernels/vmlinuz-2.6.32.41-Rocky4.2-x86_64

   scp /boot/vmlinuz-2.6.32.41-Rocky4.2-x86_64 lcliang@172.16.0.67:/home/lcliang/cd/Rocky/kernels

   rm /home/lcliang/cd/Rocky/kernels/config-2.6.32.41-Rocky4.2-x86_64

   scp /boot/config-2.6.32.41-Rocky4.2-x86_64 lcliang@172.16.0.67:/home/lcliang/cd/Rocky/kernels  

   rm /home/lcliang/cd/Rocky/kernels/System.map-2.6.32.41-Rocky4.2-x86_64

   scp /boot/System.map-2.6.32.41-Rocky4.2-x86_64 lcliang@172.16.0.67:/home/lcliang/cd/Rocky/kernels  

   rm /home/lcliang/cd/Rocky/kernels/kernel_src_info

   scp /boot/kernel_src_info lcliang@172.16.0.67:/home/lcliang/cd/Rocky/kernels

```

## 更改版本 ##

> 进入到cd目录下

1. vi tag 更改在cd目录下tag  

2. vi etc/issue 更改在cd/etc目录下issue  
   
3. vi usr/lib/setup/issue 更改在cd/usr/lib/setup/目录下issue


## 生成镜像文件 ##

1. 使用mk_iso_4.2.sh脚本根据目录生成镜像文件  

   修改xorriso的权限，命令：
   
   
```
   chmod +x xorriso  

```

   移动xorriso到/opt/下，命令
   

```
   cp xorriso /opt/  

```
   
   生成镜像文件
   
```
   mk_iso_4.2.sh /home/lcliang/cd/ rocky4.2.32-sqlproxy-2017-08-25.iso  
```

>如果缺少依赖文件可使用apt-file工具来查找  
apt-get install apt-file  
apt-file update  
apt-file search XXX文件  查找文件属于那个包  
apt-get install 安装包    
apt-file list 安装包  
根据要求修改mk_iso_4.2.sh
