下载MySQL 请耐心等待，也可以在Windows下载以后上传到 /opt/mysql目录

wget http://dev.mysql.com/get/mysql-5.7.26-1.el7.x86_64.rpm-bundle.tar

解压

tar -xvf mysql-5.7.26-1.el7.x86_64.rpm-bundle.tar

删除mariadb

//查看mariadb 是否存在 
rpm -qa|grep mari
//如果mariadb 存在的话就卸载 ，因为跟MySQL冲突
rpm -e --nodeps mariadb-libs

安装libnuma*

yum install libnuma*

安装MySQL

rpm -ivh mysql-community-common-5.7.26-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.26-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.26-1.el7.x86_64.rpm 
rpm -ivh mysql-community-server-5.7.26-1.el7.x86_64.rpm 

启动MySQL

systemctl start mysqld.service

查看密码

grep "password" /var/log/mysqld.log

c1g6u,-PBq:K 就是密码

设置你自己的密码

进入mysql 输入上面获取的密码
mysql -u root -p
假如密码是 woainijia
set password for 'root'@'localhost'=password('woainijia');
让密码立马生效
flush privileges;
