php7的最后一个版本在centos9上由于openssl以及net-snmp新版本不兼容了, 得打2个补丁才能安装

source /etc/os-release
yum -y -q --skip-broken install tcpdump iftop net-tools rsync  vim-enhanced subversion git curl nss zip unzip  wget crontabs iptables file mlocate flex diffutils   dnf dnf-plugins-core

dnf config-manager --set-enabled remi #centos7/8
dnf config-manager --set-enable crb  #centos9
dnf config-manager --set-enabled powertools  #centos8

dnf -y install libzip-devel oniguruma-devel rrdtool-devel uw-imap-devel 

支持openssl3和net-snmp5.9的补丁

MMP要简单还是直接用remi源安装吧.
