yum list installed

可以找到想下载的软件的yum安装包

我是想卸载mysql

mysql-community-client.x86_64

mysql-community-common.x86_64

mysql-community-libs.x86_64

mysql-community-release.noarch

mysql-community-server.x86_64

找到了5个安装包

然后

yum remove mysql-community-client.x86_64

yum removemysql-community-common.x86_64

yum remove mysql-community-libs.x86_64

yum remove mysql-community-release.noarch

yum remove mysql-community-server.x86_64
