CentOS7上安装PHP7时出现错误

Question

参考文档：https://webtatic.com/packages/php70/

PHP 7.0.0于2015年12月3日发布在PHP.net上，同时在Webtatic的测试库中也可通过Yum获取CentOS/RHEL 6.7和7.1版本。

我在安装php7时遇到了以下错误：

[root]# yum install php70w php70w-opcache

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

如何在CentOS7上安装PHP7？

- suspreme-dev

安装旧版本的软件包通常不是一个好主意。如果你真的需要旧版本的 php，而这个版本需要旧版本的 httpd-mmn，可以尝试使用 yum downgrade php70w-7.0.0-1.w6.x86_64 命令进行降级。如果这个命令不起作用，可以先尝试降级 httpd*，或者考虑替换 php。最后一招是在安装 php70w 之前卸载已安装的 php。 - alvits

感谢您的建议 :) 成功在CentOS7上安装了PHP7。解决方法 ==> 1.清除yum -> 2.yum安装yum-plugin-replace -> 3.替换php-common、php-xml -> 4.安装php7。 - suspreme-dev

我发现使用Remi的仓库http://rpms.famillecollet.com/比删除已有的软件包更容易/安全，这是一个有效的解决方案。

以下是我用来解决问题的步骤（选择最接近您的镜像）：

rpm -Uvh http://mirror.innosol.asia/remi/enterprise/remi-release-7.rpm
yum install php70
yum install php70-php-mysqlnd php70-php-devel php70-php-gd php70-php-mcrypt php70-php-mbstring php70-php-pear php70-php-pecl-imagick php70-php-pecl-zip

请注意，这是开发服务器所需的内容。
