CentOS 7 平滑升级 PHP 7.2 到 7.3

首先检查 PHP 版本

php -v

安装 Remi 和 EPEL 数据源

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://rpms.remirepo.net/enterprise/remi-release-7.rpm

检查 Remi 是否启用

vim /etc/yum.repos.d/remi.repo

查看 [remi] 区域的代码块是否启用，相同则不用更改：

[remi]
name=Remi's RPM repository for Enterprise Linux 7 - $basearch
#baseurl=http://rpms.remirepo.net/enterprise/7/remi/$basearch/
#mirrorlist=https://rpms.remirepo.net/enterprise/7/remi/httpsmirror
mirrorlist=http://cdn.remirepo.net/enterprise/7/remi/mirror
enabled=0
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi 

检查 Remi PHP7.3 是否启用：

vi /etc/yum.repos.d/remi-php73.repo

查看[remi-php73] 区域的代码块是否启用，相同则不用更改，默认enabled=0，修改为enabled=1

# This repository only provides PHP 7.3 and its extensions
# NOTICE: common dependencies are in "remi-safe"
