在suse 10.3中安装http apache2时出现如下的提示信息：libapr1 >= 1.0 is needed by apache2-2.2.3-16.21.i586libapr1 < 2.0 is needed by apache2-2.2.3-16.21.i586libapr-1.so.0 is needed by apache2-2.2.3-16.21.i586libaprutil-1.so.0 is needed by apache2-2.2.3-16.21.i586
此时，安装以下软件即可：libapr-util1-1.2.2-13.7.i586.rpmlibapr-util1-devel-1.2.2-13.7.i586.rpmlibapr1-1.2.2-13.2.i586.rpmlibapr1-devel-1.2.2-13.2.i586.rpm
在suse 10上装apache的时候，报错： rpm -ivh apache2-2.0.54-10.i586.rpm error: Failed dependencies:apache2-MPM is needed by apache2-2.0.54-10 原因在于要依赖于apache2-prefork-2.0.54-10.i586.rpm， 所以：rpm -ivh apache2-prefork-2.0.54-10.i586.rpm error: Failed dependencies:apache2 = 2.0.54 is needed by apache2-prefork-2.0.54-10 re，原来这两个包是相互依赖的，所以：rpm -ivh apache2-2.0.54-10.i586.rpm apache2-prefork-2.0.54-10.i586.rpm 安装成功。
这两个rpm在删除时也会出现相互依赖的问题，不能单独删除： rpm -e apache2error: Failed dependencies:apache2 = 2.0.54 is needed by (installed) apache2-prefork-2.0.54-10 rpm -e apache2-preforkerror: Failed dependencies:apache2-MPM is needed by (installed) apache2-2.0.54-10
如果删除，也必须一块删除才可以：rpm -e apache2 apache2-prefork
