mysql [MariaDB] 开启外联

1、查看mysql服务端口是否为外部端口，如果监听的是本地端口修改mariadb配置文件

root@kali:~# whereis mysql
mysql: /usr/bin/mysql /etc/mysql /usr/share/mysql /usr/share/man/man1/mysql..gz
root@kali:~# cd /etc/mysql
root@kali:/etc/mysql# ls
conf.d  debian.cnf  debian-start  mariadb.cnf  mariadb.conf.d  my.cnf  my.cnf.fallback
root@kali:/etc/mysql# cd mariadb.conf.d/
root@kali:/etc/mysql/mariadb.conf.d# ls
-client.cnf  -mysql-clients.cnf  -mysqld_safe.cnf  -server.cnf
root@kali:/etc/mysql/mariadb.conf.d# cat -server.cnf 

将bind-address改为 0.0.0.0 全局监听

root@kali:/etc/mysql/mariadb.conf.d# netstat -ant

2、mysql外部连接默认为关闭状态，开启

 GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;

3、mysql root无密码时，修改密码

UPDATE user SET password=PASSWORD('') WHERE User='root';
