Modify password refresh permissions and restart MySQL
Update user set Password=password (' own password ') where user= ' root ';
Flush privileges;
Service mysqld Restart;

Delete anonymous user

After MySQL has just been installed, there is a user name, password is empty user. This allows the database server to have the possibility of no password being logged in. To eliminate the risk, delete the anonymous user.

[[email protected] ~]# mysql-u root-p← login with root by password
Enter password:← the password here

Open MySQL remote connection under CentOS, remote Management database

2012-08-16 08:47:40| Category: MySQL | report | Font Subscription
When the server is not running PHP, not installed phpMyAdmin, remote management of MySQL is necessary. Because it is set under CentOS, the title is added to CentOS, and the following commands should be OK under the Debian system.

Mysql-u root-p MySQL # 1th MySQL is the execution command, and the 2nd MySQL is the system data name
In the MySQL console perform:

Grant all privileges on * * to ' root ' @ '% ' identified by ' telnet password, can be different from local ' with GRANT option;
# root is user name,% for any host, ' 123456 ' specified login password (this and local root password can be set differently, not affect each other)
Flush privileges; # Overloaded System permissions
Exit
Allow Port 3306

Iptables-i input-p tcp-m State--state new-m TCP--dport 3306-j ACCEPT
# See if the rules are in effect
Iptables-l-N # or: Service iptables status

# The production environment is not secure at this time, the port should be closed after remote management, and the previously added rules should be removed
iptables-d input-p tcp-m State--state new-m TCP--dport 3306-j ACCEPT
PS, above iptables Add/Remove rules are temporary, if you need to restart after the effective, you need to save the changes:
Service Iptables Save # or:/etc/init.d/iptables save
Other than that
Vi/etc/sysconfig/iptables # plus the following line of rules is OK
-A input-p tcp-m state--state new-m TCP--dport 3306-j ACCEPT

Remote management of the database software, win system can use SQLyog, with several remote software, feel this use is pretty good.

Webmin
Root
System Password

The server is multi-network card, find the network port of the public network. Use-I [Port_name] configuration allows access to tcp:22 and tcp:1521; Other protocols and ports are denied by default.
Iptables-a input-i eth1-p TCP--dport 22-j ACCEPT
Iptables-a input-i eth1-p TCP--dport 80-j ACCEPT
Iptables-a input-i eth1-p TCP--dport 10000-j ACCEPT
Iptables-a input-i eth1-j DROP
Run/etc/rc.d/init.d/iptables save config file to/etc/sysconfig/iptables

The rule is still valid after you run the service iptables restart confirm the restart Iptables.
