我对 Linux 还很陌生。我有一个 Vultr 的 VPS，想从 Apache 迁移到 Nginx。
我正在尝试遵循本指南，但是在运行此指南时：
yum install php php-mysql php-fpm
我收到此错误：
[root@j_server ~]# yum install php php-mysql php-fpm

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
我尝试谷歌搜索，但找不到解决方案。错误说有冲突，但当我运行：
rpm -qa | grep php
我得到的只有这些：
[root@j_server ~]# rpm -qa | grep php
