yum install -y lrzsz

在/usr/local目录下新建目录mysql
cd /usr/local
mkdir mysql

在/usr/local/mysql目录下使用rz -be命令上传mysql-8.0.15-1.el7.x86_64.rpm-bundle.tar

tar -xvf mysql-8.0.15-1.el7.x86_64.rpm-bundle.tar

chown mysql:mysql /var/lib/mysql -R;
systemctl start mysqld;

cat /var/log/mysqld.log | grep password查看密码
