在CentOS上安裝PHP軟件包

Question

我想找出我的CentOS服務器中的一些問題。

我的服務器中已經安裝了兩個軟件包： php-cli和php-common 。 使用命令yum info時，我會看到它們的詳細yum info 。 但是，當我使用命令yum install php-cli ，我得到了安裝這兩個軟件包的報價，就像它們根本沒有安裝在服務器上一樣。 根據info命令，已安裝的軟件包具有與服務器要安裝的軟件包相同的版本。

任何人都可以解釋嗎？

看起來好像沒有安裝那些軟件包，否則會顯示Installed Packages ，例如

Answer 2

按照“ yum”的手冊頁

"info Is used to list a description and summary information about available packages".

因此，它僅列出包，可在repositories.enter代碼中輸入
