rpm -qa | grep mariadb
rpm -e --nodeps mariadb-libs-5.5.64-1.el7.x86_64
安装包
MysqL-community-common-5.7.24-1.el7.x86_64.rpm
MysqL-community-libs-5.7.24-1.el7.x86_64.rpm
MysqL-community-libs-compat-5.7.24-1.el7.x86_64.rpm
MysqL-community-client-5.7.24-1.el7.x86_64.rpm
MysqL-community-server-5.7.24-1.el7.x86_64.rpm

报错：/usr/bin/perl is needed by MysqL-community-server-5.7.19-1.el7.x86_64
缺少net-tools.x86_64，libaio.x86_64，perl.x86_64三个依赖，使用yum安装即可。
-
yum -y install perl.x86_64
-
yum install -y libaio.x86_64
-
yum -y install net-tools.x86_64
