A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !

You will find that password in '/root/.mysql_secret'.

You must change that password on your first connect,

no other statement but 'SET PASSWORD' will be accepted.

See the manual for the semantics of the 'password expired' flag.

Also, the account for the anonymous user has been removed.

In addition, you can run:

  /usr/bin/mysql_secure_installation

which will also give you the option of removing the test database.

This is strongly recommended for production servers.

See the manual for more instructions.

Please report any problems at http://bugs.mysql.com/

WARNING: Found existing config file /usr/my.cnf on the system.

Because this file might be in use, it was not replaced,

but was used in bootstrap (unless you used --defaults-file)

and when you later start the server.

The new default config file was created as /usr/my-new.cnf,

please compare it with your file and take the changes you need.

四、配置datadir路径

vi /usr/my.cnf

datadir=/data

启动

mysqld_safe &

service mysql start

五、修复数据

[Err] 1034 - Incorrect key file for table 'm_request_record'; try to repair it

mysql> repair table m_request_record;

退出mysql,执行如下修复动作:
