https://www.mysql.com/downloads/
到页面最底部，点击社区版 community(GPL)Downloads>>，进入
https://dev.mysql.com/downloads/
继续点击社区版服务器，进入
https://dev.mysql.com/downloads/mysql/
三、选择版本及系统，点击右侧的Download，进入页面
四、最后开始下载
五、下载完成后的包列表
陈列如下
mysql-community-client-8.0.16-2.el7.x86_64.rpm
mysql-community-common-8.0.16-2.el7.x86_64.rpm
mysql-community-devel-8.0.16-2.el7.x86_64.rpm
mysql-community-embedded-compat-8.0.16-2.el7.x86_64.rpm
mysql-community-libs-8.0.16-2.el7.x86_64.rpm
mysql-community-libs-compat-8.0.16-2.el7.x86_64.rpm
mysql-community-server-8.0.16-2.el7.x86_64.rpm
mysql-community-test-8.0.16-2.el7.x86_64.rpm
六、移除系统原有MySQL包
七、依次安装如下几个rpm包
mysql-community-common-8.0.16-2.el7.x86_64.rpm
mysql-community-libs-8.0.16-2.el7.x86_64.rpm
mysql-community-client-8.0.16-2.el7.x86_64.rpm
mysql-community-server-8.0.16-2.el7.x86_64.rpm
八、初始化mysql
mysqld --initialize --user=mysql
九、查看默认的初始密码
cat /var/log/mysqld.log
十、登录mysql
首先启动mysql服务
service mysqld start
查看一下服务状态是否启动
service mysqld status
使用原始密码登录mysql
mysql -uroot -pdKQqGsDln7?1
修改mysql密码为
root
alter user 'root'@'localhost' identified by 'root';
新密码登录mysql
mysql -uroot -proot
至此mysql8安装配置完成
