rpm –ivh             安装rpm 包

    rpm升级
rpm –Uvh sendmail-8.9.3-10.i386.rpm


    rpm –qa | grep …        查当前安装的rpm包

    rpm -q telnet-server


    卸载RPM软件包------rpm -e
    最基本的卸载例子
# rpm -qa | grep php                卸前先查
php-ldap-5.0.4-10
php-5.0.4-10
php-pear-5.0.4-10
# rpm -e php-pear-5.0.4-10 php-5.0.4-10 php-ldap-5.0.4-10
可以一次卸载多个
# rpm -qa | grep php


    卸载中常见的依赖错误
# rpm -qa | grep httpd
system-config-httpd-1.3.2-2
httpd-2.0.54-10

# rpm -e httpd-2.0.54-10

卸不掉，很多软件依赖它，只能把依赖软件先卸掉

    rpm  --nodeps （不检查依赖性）
因为linux的一些bug,有些软件是相互依赖的，先装/卸哪个都不行，就得用nodeps这个参数才行。
下边的“死循环”，你需要我，我需要你
[root@nm http]# rpm -ivh httpd-suexec-2.0.52-25.ent.i386.rpm
warning: httpd-suexec-2.0.52-25.ent.i386.rpm: V3 DSA signature: NOKEY, key ID db42a60e
error: Failed dependencies:
        httpd = 2.0.52-25.ent is needed by httpd-suexec-2.0.52-25.ent.i386
    Suggested resolutions:
        httpd-2.0.52-25.ent.i386.rpm

[root@nm http]# rpm -ivh httpd-2.0.52-25.ent.i386.rpm
warning: httpd-2.0.52-25.ent.i386.rpm: V3 DSA signature: NOKEY, key ID db42a60e
error: Failed dependencies:

    Suggested resolutions:
        httpd-suexec-2.0.52-25.ent.i386.rpm
解决：一个--nodeps不依赖，一个正常的依赖
[root@nm http]# rpm -ivh --nodeps httpd-2.0.52-25.ent.i386.rpm
