rpm -qa | grep -i mysql
//若已安装过,会出现以下
MySQL-server-5.0.22-0.i386
MySQL-client-5.0.22-0.i386
//输入以下命令删除它:
# rpm -ev MySQL-server-5.0.22-0.i386
# rpm -ev MySQL-client-5.0.22-0.i386
//若删除的时候,出现删除不成功,出现依赖的包,前提必须删除依赖项。
rpm -ivh /opt/MySQL-server-5.5.15-1.linux2.6.x86_64.rpm
若遇到Header V3 DSA signature: NOKEY
原因:这是由于yum安装了旧版本的GPG keys造成的
解决办法:后面加上
–force –nodeps
如:
rpm -ivh MySQL-server-5.5.46-1.linux2.6.x86_64.rpm –force –nodeps
从 RPM 版本 4.1 开始,在安装或升级软件包时会检查软件包的签名。
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
引用
rpm –import /etc/pki/rpm-gpg/RPM*
再安装软件就不会有这个错误提示了。
rpm -ivh MySQL-client-5.6.15-1.el6.x86_64.rpm
