【Linux】CentOS6上mysql5.7安裝

1.下載安裝yum源

根據系統下載yum源

https://dev.mysql.com/downloads/repo/yum/

rpm -ivh xxxxx.rpm

2.修改yum源

vim /etc/yum.repos.d/mysql-community.repo

enable想要下載的版本

3.安裝mysql

yum install mysql-community-server

4.啓動

配置裏修改瞭如下datadir路徑

vim /etc/my.cnf

啓動服務

service mysqld start

查看root初始密碼

grep 'temporary password' /var/log/mysqld.log

登陸數據庫

shell> mysql -uroot -p

 

此時使用會報錯「You must reset your password using ALTER USER statement before executing this statement.」 

使用如下步驟設置新密碼：

step 1: SET PASSWORD = PASSWORD('your new password');

step 2: ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;

step 3: flush privileges;

 設置完成後從新登陸數據庫
