Linux(CentOS7)下安裝Mysql8數據庫

1、Linux版本

2、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/

3、選擇版本及系統，點擊右側的Download，進入頁面

4、最後開始下載

5、下載完成後的包列表

陳列以下

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

6、移除系統原有MySQL包

7、依次安裝以下幾個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

8、初始化mysql

mysqld --initialize --user=mysql

9、查看默認的初始密碼

cat /var/log/mysqld.log

10、登陸mysql

首先啓動mysql服務

service mysqld start

查看一下服務狀態是否啓動

service mysqld status

使用原始密碼登陸mysql

mysql -uroot -pdKQqGsDln7?1

修改mysql密碼爲root

alter user 'root'@'localhost' identified by 'root';

新密碼登陸mysql

mysql -uroot -proot

至此mysql8安裝配置完成
