作者: ginceo  出自:

在RedHat Linux上安装php-5.2.5需要升级Linux自带的libxml2库，但是libxml2有很多的依赖（dependencies），下面是我的升级方式。

libxml2的官方下载地址是

首先移除libxml2-python-2.5.4-1，我的是libxml2-python-2.5.4-1

根据你自己系统的实际版本

[root@WebServer root]# rpm -e libxml2-python-2.5.4-1
error: Failed dependencies:
libxml2-python is needed by (installed) redhat-config-packages-1.1.8-1

发现有依赖关系，于是查询
[root@WebServer root]# rpm -qa | grep redhat-config-packages
redhat-config-packages-1.1.8-1

移除
[root@WebServer root]# rpm -e redhat-config-packages-1.1.8-1

然后再次移除libxml2-python-2.5.4-1
[root@WebServer root]# rpm -e libxml2-python-2.5.4-1

移除成功，查看确认
[root@WebServer root]# rpm -qa | grep libxml2
libxml2-2.5.4-1
libxml2-devel-2.5.4-1

移除libxml2-devel-2.5.4-1
[root@WebServer root]# rpm -e libxml2-devel-2.5.4-1

移除libxml2-2.5.4-1
[root@WebServer root]# rpm -e libxml2-2.5.4-1

由于依赖关系移除失败

用升级方式覆盖安装
