然后我在我的服务器上安装了remi存储库

rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

这些命令已成功安装存储库

现在升级PHP的命令

yum --enablerepo=remi,remi-test update httpd MysqL MysqL-server PHP PHP-common

但它失败,出现以下错误消息

Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
Error: Cannot retrieve Metalink for repository: epel. Please verify its path and try again

如果我尝试yum info PHP相同的错误消息

基本上在安装这些存储库之后,yum不起作用,但是yum工作得更早了.

如果我删除这些存储库并尝试yum它没有任何错误.

如何将PHP升级到PHP 5.4.11版本？

正如@Michael建议我跑了

yum clean all
Loaded plugins: fastestmirror
Cleaning repos: base epel extras updates
Cleaning up Everything
Cleaning up list of fastest mirrors
`[root@www ~]# yum --obsoletes update
Loaded plugins: fastestmirror
Determining fastest mirrors
Error: Cannot retrieve Metalink for repository: epel. Please verify its path and try again

还是一样的错误

正如@Michael建议我跑了

URLGRABBER_DEBUG = 1 yum check-update
它最终出现以下错误

Problem with the SSL CA cert (path? access rights?)

因此,实际问题是SSL证书,但为什么它抱怨SSL证书,但它是有效的
