CentOS 7升级php至7.2

一、卸载已有php

1. 查看php依赖包

rpm -qa | grep php

2. 按依赖顺序进行删除，删除不干净，再将剩余删除一遍

rpm -e php-fpm-5.3.3-22.el6.x86_64
//等等

3. 安装php7.2

yum -y install php72w php72w-cli php72w-common php72w-devel php72w-embedded php72w-fpm php72w-gd php72w-mbstring php72w-mysqlnd php72w-opcache php72w-pdo php72w-xml php72w-mcrypt php72w-intl

4. 启动

systemctl start php-fpm
