mysql - yum 更新出现 'Obsoleted by ...' 错误

Question

我的操作系统是CentOS 6.9，我正在尝试通过此链接将 mysql 5.5 升级到 5.7:https://support.plesk.com/hc/en-us/articles/213403429-How-to-upgrade-MySQL-5-5-to-5-6-5-7-or-MariaDB-5-5-to-10-0-10-1-10-2-on-Linux

但是# yum update mysql给了我错误:

我尝试了yum cleanmetadata和yum clean all几次，但它不起作用。请帮助我。

Answer 1

我建议从php-mysql(使用libmysqlclient)切换到php-mysqlnd，它使用PHP native 驱动程序提供相同的扩展集。

yum shell
> remove php-mysql
> install php-mysqlnd
> run

这将消除依赖性，从而解决您的问题。

顺便说一句，请注意 PHP 5.4.45 已达到生命周期的终点，因此我也衷心建议您更新到维护版本(5.6+)

附言任何 PHP 版本 >= 5.5 的所有 RPM 均仅提供 php-mysqlnd 软件包。
