我试图将PHP从5.5.8降级到5.3.x. 我已经尝试过，但它为我工作。
yum downgrade php 我得到的错误是
Loaded plugins: fastestmirror, refresh-packagekit, security Setting up Downgrade Process Loading mirror speeds from cached hostfile * Webmin: webmin.mirror.somersettechsolutions.co.uk * base: centos.excellmedia.net * epel: epel.mirror.net.in * extras: centos.excellmedia.net * updates: centos.excellmedia.net No Match for available package: php-5.3.3-26.el6.x86_64 Nothing to do
我也尝试过这个，但是即使这个力量也适合我。
sudo yum downgrade php php-common php-cli
我得到的错误日志是

请帮我一下
看来你已经从remi仓库安装了很多额外的PHP模块。 当您降级PHP时，依赖关系不再可用。 你也可以尝试降级它们
yum downgrade php*
但是这也可能会失败，因为并不是所有这些软件包都可以在标准仓库中使用
我build议先删除所有的PHP包：
yum remove php*
之后，您可以从标准仓库重新安装所需的软件包：
yum install php php-cli ...
