모든 IP 허용

INSERT INTO mysql.user (host,user,authentication_string,ssl_cipher, x509_issuer, x509_subject) VALUES ('%','root',password('패스워드'),'','','');
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%';
FLUSH PRIVILEGES;

> BIND-ADRESS 변경

/etc/mysql/my.cnf    (or)  /etc/mysql/mysql.conf.d/mysqld.cnf

아래 line을 주석처리 하거나 (0.0.0.0) 으로 변경

bind-address = 127.0.0.1

root# service mysql restart
