4. How to open Mysql remote access under Ubuntu
4.1 Open port 3306
First confirm whether port 3306 is open to the public. By default, mysql is not open to external access. The viewing method is as follows:
# netstat -an | grep 3306 tcp 0 0 127.0.0.1:3306 0.0.0.0:* LISTEN
As can be seen from the above, mysql port 3306 is just listening for local connections 127.0.0.1. We make changes to make it open to other addresses. Open /etc/mysql/my.cnffile
# vim /etc/mysql/my.cnf
Find bind-address = 127.0.0.1this line, probably on line 47, we will comment it out.
4.2 Remote access by authorized users
In order to allow users who access the mysql client to have access rights, we can authorize users by the following methods: First enter mysql
# mysql -uroot -p
#Enter your_password
Authorization:
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'your_password' WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES;
Otherwise, the following problems will occur
Access denied for user 'root'@'192.168.1.148' (using password: YES)
4.3 Restart the mysql service to make the configuration take effect
The restart method is simple:
# sudo service mysql restart
