Linux/centos open MySQL remote connection, remote management database

When the server is not running PHP, not installed phpMyAdmin, remote management of MySQL is necessary.

First step: Turn on remote access for MySQL users

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 ' 123456 ' with Grant option;# root is the username,% represents any host, ' 123456 ' specified login password (this and this The root password of the ground can be set different, non-affected) flush privileges; # overloaded system permissions exit;

If you want to allow user root to connect to the MySQL service from a host that is IP 192.168.137.99:

Grant all privileges on * * to ' root ' @ ' 192.168.137.99 ' identified by ' 123456 ' with grant Option;flush privileges;

Step two: Set up a firewall to allow 3306 ports to be accessed externally

Iptables-i input-p tcp-m State--state new-m TCP--dport 3306-j accept# See if the rule is 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 administration, and the rule added before the deletion iptables-d input-p tcp-m State--state new-m TCP--dport 3306-j ACCEPT

Note : the above iptables Add/Remove rules are temporary and will need to be saved if a reboot is required:

Service Iptables Save # or:/etc/init.d/iptables save

Other than that

Vi/etc/sysconfig/iptables # plus the following line of rules is also possible-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.
