我正在尝试在 CentOS 5.4 上将 php 5.1 升级到 5.2
我用：
yum upgrade php
结果是这样的（查看最后一部分）：
[root@mail httpd]# yum update php

You could try using --skip-broken to work around the problem
You could try running: package-cleanup --problems
package-cleanup --dupes
rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.
[root@mail httpd]#
使用 --skip-broken 会有什么后果？有什么建议吗？
答案1
您的 php-eaccelerator 版本与您当前的 PHP 版本相关联。通常，它会自动更新，但我猜想这个包要么是手动安装的，没有使用存储库，要么存储库没有与您要安装的较新 PHP 兼容的版本。
如果您 skip-broken 或 --exclude php-eaccelerator，PHP 将升级，但该模块可能无法工作。
如果您随后可以找到新版本的 php-eaccelerator 并单独安装，那就完全没问题了。
答案2
使用 yum remove php 删除默认 PHP。然后，您可以使用以下方式更新到 PHP 5.3.x
yum 更新 php53
该选项在 Centos 5.6 发布时（2011 年 4 月）可用。
我们都对 RHEL/Centos 默认 php (5.1.6) 感到“失望”。另外，使用其他 repos 进行 php/mysql 更新也是个好主意（例如 Remi、Utter Ramblings、EPEL、CentOS ALT 等）...
此致
