mysql5.7安裝完成后普通用戶不能進(jìn)mysql,原因:root的plugin被修改成了auth_socket,用密碼登陸的plugin應(yīng)該是mysql_native_password,直接用root權(quán)限登錄就不用密碼,修改root密碼和登錄驗(yàn)證方式
$ sudo su # mysql mysql> mysql> select user, plugin from mysql.user; +------------------+-----------------------+ | user | plugin | +------------------+-----------------------+ | root | auth_socket | | mysql.session | mysql_native_password | | mysql.sys | mysql_native_password | | debian-sys-maint | mysql_native_password | +------------------+-----------------------+ 4 rows in set (0.00 sec) mysql> update mysql.user set authentication_string=PASSWORD('123456'), plugin='mysql_native_password' where user='root'; mysql> flush privileges; mysql> exit Bye # exit $ sudo /etc/init.d/mysql restart $ mysql -uroot -p Enter password: Welcome to the MySQL monitor.
