centos7 開放3306埠並可以遠端訪問

開啟遠端訪問：

允許任何ip以root使用者登入

grant all privileges on *.* to 'root'@'%' identified by 'root' with grant option;

flush privileges;#立即生效

1、關閉firewall：

systemctl stop firewalld.service

systemctl disable firewalld.service
systemctl mask firewalld.service

yum install iptables-services -y

# systemctl enable iptables

# systemctl start iptables

systemctl status iptables

vi /etc/sysconfig/iptables

-a input -m state --state new -m tcp -p tcp --dport 22 -j accept

-a input -m state --state new -m tcp -p tcp --dport 80 -j accept

-a input -m state --state new -m tcp -p tcp --dport 3306 -j accept

:wq! #儲存退出

3.重啟配置，重啟系統

systemctl restart iptables.service #重啟防火牆使配置生效

systemctl enable iptables.service #設定防火牆開機啟動
