Additional CentOS software package and additional centos Software Package

I am a beginner in CentOS. The installation software is very different from that in windows. Most of them have to use yum install xxx.
This has a problem. On the one hand, yum resources are limited, and on the other hand, yum is installed in a lower version by default.
For example, in CentOS7, yum install php gets the php5.4 version. If you want to install a later version, the official php solution is to download the source code, decompress and compile it; this is very scary for linux.
Some additional software packages were found during the learning process, that is, more options can be found through yum.
The following three methods are found:
1. CentOS users can directly install and enable the epel source through yum install EPEL-release. Https://fedoraproject.org/wiki/EPEL/zh-cn
