SUCCESS! MysqL running (2670)
-bash-4.2$ MysqL -u root -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
以下是密码忘记的解决方法:
修改MysqL的参数设置:
# vi /etc/my.cnf
在[MysqLd]的段最后一行加上一句:skip-grant-tables
例如:
[MysqLd]
........................
log-bin=MysqL-bin
innodb_data_file_path = ibdata1:12M;ibdata2:100M;ibdata3:300M:autoextend
innodb_file_per_table=on
max_connections=500
skip-grant-tables --新增加行
保存并且退出vi.
重启MysqL服务:
[root@chenfeng subsys]# service MysqL restart
Shutting down MysqL. SUCCESS!
Starting MysqL. SUCCESS!
-bash-4.2$ MysqL --不用输密码直接登录
