在suse 10.3中安裝http apache2時(shí)出現(xiàn)如下的提示信息：

libapr1 >= 1.0 is needed by apache2-2.2.3-16.21.i586
libapr1 < 2.0 is needed by apache2-2.2.3-16.21.i586
libapr-1.so.0 is needed by apache2-2.2.3-16.21.i586
libaprutil-1.so.0 is needed by apache2-2.2.3-16.21.i586

此時(shí)，安裝以下軟件即可：

libapr-util1-1.2.2-13.7.i586.rpm
libapr-util1-devel-1.2.2-13.7.i586.rpm
libapr1-1.2.2-13.2.i586.rpm
libapr1-devel-1.2.2-13.2.i586.rpm

在suse 10上裝apache的時(shí)候，報(bào)錯(cuò)： 

rpm -ivh apache2-2.0.54-10.i586.rpm
error: Failed dependencies:
apache2-MPM is needed by apache2-2.0.54-10

原因在于要依賴于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，原來這兩個(gè)包是相互依賴的，所以：
rpm -ivh apache2-2.0.54-10.i586.rpm apache2-prefork-2.0.54-10.i586.rpm
安裝成功。

這兩個(gè)rpm在刪除時(shí)也會出現(xiàn)相互依賴的問題，不能單獨(dú)刪除：

rpm -e apache2
error: Failed dependencies:
apache2 = 2.0.54 is needed by (installed) apache2-prefork-2.0.54-10
rpm -e apache2-prefork
error: Failed dependencies:
apache2-MPM is needed by (installed) apache2-2.0.54-10

如果刪除，也必須一塊刪除才可以：
rpm -e apache2 apache2-prefork
