离线安装

2个文件 丢到/software目录下

检查是否有mysql

检查是否安装（没有安装过mysql，可以跳过）

有的话，卸载

rpm -e --nodeps mysql-libs-你刚刚自己查的包

yum remove mysql mysql-server mysql-libs mysql-server;

rpm -e --nodeps pcp-pmda-mysql-3.10.6-2.el7.x86_64

如果提示没有perl,则安装(可用本地离线镜像源）Centos7，离线yum源下载，搭建_我要用代码向我喜欢的女孩表白的博客-CSDN博客_centos7yum源下载

yum install -y perl-Module-Install.noarch

清除缓存的相关包

yum remove mysql-libs
 
yum remove mariadb-libs

进入目录解压

tar -xvf mysql-5.7.31-1.el7.x86_64.rpm-bundle.tar

rpm -ivh mysql-community-common-5.7.31-1.el7.x86_64.rpm
 
rpm -ivh mysql-community-libs-5.7.31-1.el7.x86_64.rpm

若rpm -ivh mysql-community-server-5.7.31-1.el7.x86_64.rpm 出现问题,否则跳过
