我必须在我的 CentOS 服务器上安装 PHP 5.3。如果我这样做yum install php，基础存储库会安装 5.1.6，这对于我需要安装的应用程序来说太旧了。所以我一直在尝试使用IUS存储库，遵循IUS的官方说明：
root@linuxbox ~]# wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/ius-release-1-2.ius.el5.noarch.rpm
root@linuxbox ~]# wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/epel-release-1-1.ius.el5.noarch.rpm
root@linuxbox ~]# rpm -Uvh ius-release*.rpm epel-release*.rpm
好的。现在我只是做yum install php53, 等等 我需要的一切......但我收到了这个错误：
Running rpm_check_debug
