一、安装MySQL
[[email protected] src]# rpm -ivh mysql57-community-release-el7-8.noarch.rpm
error: Failed dependencies:
mysql57-community-release conflicts with (installed) mysql80-community-release-el7-1.noarch
在安装包后面加两个参数，如 ：
[email protected] src]# rpm -ivh http://repo.mysql.com/yum/mysql-5.6-community/el/6/x86_64/mysql-community-release-el6-5.noarch.rpm --nodeps --force
Retrieving http://repo.mysql.com/yum/mysql-5.6-community/el/6/x86_64/mysql-community-release-el6-5.noarch.rpm

二、安装rpm包时经常会遇到
warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID*****
这是由于yum安装了旧版本的GPG keys造成的，解决办法就是
rpm --import /etc/pki/rpm-gpg/RPM*
三、执行卸载命令
rpm –e ImageMagick-6.2.8.0-4.el5_1.1
error: “ImageMagick-6.2.8.0-4.el5_1.1” specifies multiple packages
rpm –e ImageMagick-6.2.8.0-4.el5_1.1 --nodeps
error: “ImageMagick-6.2.8.0-4.el5_1.1” specifies multiple packages
如果卸载的时候提示与其他包存在依赖关系，可以一个个卸载提示的程序，也可以使用–nodeps 参数，不考虑依赖关系而直接卸载。
rpm -e ImageMagick-6.2.8.0-4.el5_1.1 --allmatches --nodeps
四、 centos下mysql rpm包安装报错 NOKEY的问题
rpm -ivh mysql-community-server-5.7.10-1.el5.i686.rpm
warning: mysql-community-server-5.7.10-1.el5.i686.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
error: Failed dependencies:
解决办法:
rpm -ivh mysql-community-server-5.7.10-1.el5.i686.rpm --nodeps --force
五、安装Samba服务器时候使用CD挂载安装的，结果遇到如下报错
not an rpm package (or package manifest)：Input/output error //报错信息
解决方法：重新下载新的RPM安装包，原因是因为RPM包有损坏，多发生在挂在CD的情况下
