一、Linux版本
二、先下載Linux下的Mysql包，打開Mysql官網
https://www.mysql.com/
點擊DOWNLOAD，進入
https://www.mysql.com/downloads/
到頁面最底部，點擊社區版 community(GPL)Downloads>>，進入
https://dev.mysql.com/downloads/
繼續點擊社區版服務器，進入
https://dev.mysql.com/downloads/mysql/
三、選擇版本及系統，點擊右側的Download，進入頁面
四、最后開始下載
五、下載完成后的包列表
陳列如下
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、移除系統原有MySQL包
七、依次安裝如下幾個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、查看默認的初始密碼
cat /var/log/mysqld.log
十、登錄mysql
首先啟動mysql服務
service mysqld start
查看一下服務狀態是否啟動
service mysqld status
使用原始密碼登錄mysql
mysql -uroot -pdKQqGsDln7?1
修改mysql密碼為
root
alter user 'root'@'localhost' identified by 'root';
新密碼登錄mysql
mysql -uroot -proot
至此mysql8安裝配置完成
