CentOS7 安装mysql8.0（YUM方式）

 1.下载mysql源安装包

shell> wget  http://dev.mysql.com/get/mysql80-community-release-el7-1.noarch.rpm   2.安装mysql源 shell>  yum localinstall mysql80-community-release-el7-1.noarch.rpm   3.检查mysql源是否安装成功 shell> yum repolist enabled | grep "mysql.*-community.*"   4.修改 vim /etc/yum.repos.d/mysql-community.repo源 ，改变默认安装的mysql版本。比如要安装5.6版本，将5.7源的enabled=1改成enabled=0。然后再将5.6源的enabled=0改成enabled=1即可。

2）连接mysql shell>  mysql -uroot -p 3）修改密码 [注意：后面的分号一定要跟上] mysql> ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘MyNewPass4!‘; 或者： mysql> set password for ‘root‘@‘localhost‘=password(‘MyNewPass4!‘);    mysql> show variables like ‘%password%‘;     9.添加远程登录用户 mysql> GRANT ALL PRIVILEGES ON *.* TO ‘caoxiaobo‘@‘%‘ IDENTIFIED BY ‘Caoxiaobo0917!‘ WITH GRANT OPTION;
