在CentOS上安装PHP包

Question

I want to figure out some issue in my CentOS server.

I have two packages that already installed in my server: php-cli and php-common. I see their details when i use the command yum info. However, when i use the command yum install php-cli, i get an offer to install these two packages, like they are not installed on the server at all. According to the info command, the packages that already installed have the same version of the packages that the server offering to install.

Anyone can explain that?

Is this ok [y/N]: 

Answer 1

Doesn't look like those packages are installed, otherwise it would say Installed Packages, e.g.
