是因为没有配置文件 （添加配置 文件即可）
mkdir /wwwRoot/mysql
chowm -R mysql:mysql /wwwRoot/mysql

[client] 　　　　　　
#客户端设置，即客户端默认的连接参数
#port = 3306　　　　　　　　 　　　　　　　　
#默认连接端口

mysql 默认给了给临时密码
cat /wwwRoot/mysql/error.log
[Note] A temporary password is generated for root@localhost: =cQ/tj)!)3y5

用 =cQ/tj)!)3y5 用这个临时密码登录修改密码
set password for root@localhost = password('123456');

如果找不到临时密码
就启动 不需要密码登录
[mysqld]
datadir=/wwwRoot/mysql
skip-grant-tables=true

启动后 mysql -h 127.0.0.1 直接登录
修改密码 set password for root@localhost = password('123456');

如果报错：ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement
执行 ： flush privileges ;
在修改密码

support-files/mysql.server start 启动数据库
