mysql 5.6 以上版本安装时会有一个随机密码，在mysql日志里查询
cat /var/log/mysqld.log |grep "A temporary password" [Note] A temporary password is generated for root@localhost: Thm34de873
Thm34de873就是此次mysql 5.7安装的随机密码.
开启mysqlserver服务，尝试登陆成功。
systemctl start mysqld mysql -u root -p Enter password: Thm34de873 Welcome to the MySQL monitor. Commands end with ; or \g.

mysql 5.7 执行操作前要求必须更改初始密码，新密码写在单引号‘‘里。
ERROR 1820 (HY000): You must SET PASSWORD before executing this statement
mysql> SELECT 1;ERROR 1820 (HY000): You must SET PASSWORD before executing this statement mysql> SET PASSWORD = PASSWORD(‘new_password‘); Query OK, 0 rows affected (0.01 sec) mysql> SELECT 1;+---+ | 1 | +---+ | 1 | +---+ 1 row in set (0.00 sec)
密码有强度要求，如要关闭，在/etc/my.cnf中添加validate-password=OFF
