rpm要使用的U選項？

Question

我想升級我的安裝組件，以這樣的方式，那也只是specfied文件被替換和結構不會改變

rpm -qlp CDA-4.2.1-201203020211.i386.rpm 
/opt/CDA/agent/bin/agent_client 
/opt/CDA/agent/bin/Agent 
/opt/CDA/agent/bin/cda_agent 
/opt/CDA/agent/conf/agent.conf 
/opt/CDA/agent/conf/agent.ini 


rpm -qlp CDA-4.2.1.1-201203020211.i386.rpm 
/opt/CDA/agent/bin/Agent 




    installed component CDA-4.2.1-201203020211.i386.rpm 
     when i do rpm -U CDA-4.2.1.1-201203020211.i386.rpm 
      all the files get remvoved excpet /opt/CDA/agent/bin/Agent, 
     i'm struggling with the right rpm -U addional options, 
     i want only /opt/CDA/agent/bin/Agent to be replaced 

我需要防止刪除所有舊版本的包，和剛剛更換存在的新文件

新的rpm必須包含所有文件，而不僅僅是要更新的文件。如果列出文件爲%config(noreplace)，則在更新期間它們不會被替換，而是如果安裝的文件已更改，則將在安裝更新的rpm之後創建X.rpmnew文件。換句話說你的CDA.spec應該有：

... 
%files 
... 
%config(noreplace) /opt/CDA/agent/conf/agent.ini # similar for other config files 
...
