CentOS7官方源的php是7.2版本的，不够WordPress的最低要求。 不多说，直接给干到最新版。
先卸载从官方源下载的PHP以及依赖：
yum remove php -y
yum autoremove下载源码包并解压进入源码目录：
yum install wget -y
wget https://www.php.net/distributions/php-8.0.12.tar.gz
tar xzf php-8.0.12.tar.gz
cd php-8.0.12下载喜闻乐见的工具包和依赖们：
yum install epel-release -y
yum groupinstall "Development tools" -y
yum install libxml2-devel sqlite-devel oniguruma-devel httpd-devel \
mysql-devel enchant-devel libffi-devel libwebp-devel \
libXpm-devel libiodbc-devel libsodium-devel libxslt-devel \
libcurl-devel libpng-devel libjpeg-devel freetype-devel \
systemd-devel libacl-devel valgrind-devel libicu-devel \
