yum第三方安装-软件包没签名及更新错误
yum安装时 后面加 --nogpgcheck
阿里云源文件:http://mirrors.aliyun.com/repo/Centos-7.repo
epel repo源:http://mirrors.aliyun.com/repo/epel-7.repo
yum update
错误提示 Error: initscripts conflicts with centos-release-7-4.1708.el7.centos.x86_64 意思是相冲突了,既然冲突就排除掉;定位到错误关键词为 initscripts;
yum update --exclude=kernel* --exclude=centos-release* --exclude=initscripts*
此命令(yum update –exclude=kernel* –exclude=centos-release* –exclude=initscripts*)模式下升级方可正常
或者:rpm -e redhat-release-server-7.0-1.el7.x86_64 --nodeps 删除冲突的包
