MySQL5.7之開啓遠程鏈接

    Centos7上，對MySQL5.7開啓遠程鏈接。

1.修改/etc/my.cnf

[mysqld]
validate_password=off

2.命令行進入mysql

use mysql;
GRANT ALL ON *.* TO root@'%' IDENTIFIED BY '密碼' WITH GRANT OPTION;
flush privileges;

3.與防火牆有關

firewall-cmd --zone=public --add-port=3306/tcp --permanent
firewall-cmd --reload

4.在Navicat中鏈接就能夠了。
