自己生成AIX bff打包安装文件

复杂度3/5
机密度4/5

最后更新2021/04/28

AIX提供了生成打包文件的命令：mkinstallp，需要安装bos.adt.insttools fileset
查看fileset是否已经安装：

#lslpp -L bos.adt.insttools
  Fileset                      Level  State  Type  Description (Uninstaller)
  ----------------------------------------------------------------------------
  bos.adt.insttools         7.1.3.15    C     F    Tool to Create installp Packages

• 准备
  先要准备一个安装目录：

#mkdir -p ~/build/mypackage

把安装包需要的文件放到对应的目录和子目录下：

~/build/mypackage/usr/local/bin/my_execution
~/build/mypackage/usr/local/filepackage/my_files
~/build/mypackage/usr/local/filepackage/lib/my_libs

mkinstallp命令使用一个template文件控制如何生成安装文件，下面是一个最简单模板文件的例子：

#cat ~/build/mypackage/template
Package Name: my_package
Package VRMF: 1.0.0.0
Update: N
Fileset
  Fileset Name: mypackage.rte
  Fileset VRMF: 1.0.0.0
  Fileset Description: bff packaging process template
  Bosboot required: N
  License agreement acceptance required: N
  Include license files in this package: N
  Requisites:
  USRFiles
     /usr/local/bin/my_execution
     /usr/local/filepackage/my_files
     /usr/local/filepackage/lib/my_libs
  EOUSRFiles
  USRLIBLPPFiles
  EOUSRLIBLPPFiles
  ROOT Part: N
  ROOTFiles
  EOROOTFiles
EOFileset

VRMF 表示此fileset对应的版本号Version, 发布号Release, 维护级别Maintenance level, 补丁级别Fix

模板文件中的USRFiles段说明在安装包中有哪些文件，以及安装的目标位置；

ROOTFiles表示不同机器之间不能共享的文件，仅仅用于AIX无盘工作站使用，目前已经没有什么用处，通常都是N；

• 生成包
  生成命令非常简单：

# mkinstallp -d ~/build/mypackage -T ~/build/mypackage/template
Using ~/build/mypackage as the base package directory.
Cannot find ~/build/mypackage/.info. Attempting to create.
Using ~/build/mypackage/.info to store package control files.
Cleaning intermediate files from ~/build/mypackage/.info.

Using ~/build/mypackage/template as the template file.
vopt_manager 1.0.0.0 I
processing mypackage.rte
creating ./.info/liblpp.a
creating ./tmp/mypackage.1.0.0.0.bff

• 安装
  安装刚生成的安装包

 # cd ./tmp
 # inutoc .
 # installp -acXgd . mypackage.rte

You can see your package content with lslpp :

 # lslpp -f mypackage.rte

  Fileset               File

     /usr/local/bin/my_execution
     /usr/local/filepackage/my_files
     /usr/local/filepackage/lib/my_libs

如果重新build，要先把.info和tmp子目录删掉：

#rm -rf tmp .info

• 更进一步
  前面只完成了最基础的打包过程，如果想在安装之前、之后做一些额外动作怎么办？还有pre/post script可以帮助实现这个目标。

生成相应的脚本：

 echo 'echo PRE INSTALL' > /tmp/pre_install.sh
 echo 'echo POST INSTALL' > /tmp/post_install.sh
 echo 'echo PRE REMOVAL' > /tmp/pre_removal.sh
 chmod u+x /tmp/pre_install.sh /tmp/post_install.sh /tmp/pre_removal.sh

修改模板文件：

#cat ~/build/mypackage/template
Package Name: mypackage
Package VRMF: 1.0.0.0
Update: N
Fileset
  Fileset Name: mypackage.rte
  Fileset VRMF: 1.0.0.0
  Fileset Description: bff packaging process template
  Bosboot required: N
  License agreement acceptance required: N
  Include license files in this package: N
  Requisites:
  USRFiles
     /usr/local/bin/my_execution
     /usr/local/filepackage/my_files
     /usr/local/filepackage/lib/my_libs
  EOUSRFiles
  USRLIBLPPFiles
     Pre-installation Script: /tmp/pre_install.sh
     Post-installation Script: /tmp/post_install.sh
     Pre-deinstall Script: /tmp/pre_removal.sh
  EOUSRLIBLPPFiles
  ROOT Part: N
  ROOTFiles
  EOROOTFiles
EOFileset

现在我们把这些脚本放到了绝对目录/tmp中，其实也可以放到build目录下，但脚本编写一定要注意在build目录下的时候，真正执行时的所在目录其实是刨除build父目录之后的位置。下面是安装时的屏显：
