I just Installed CentOS7 and faced some issues in installing and connecting MySQL from remote location.
I used to do a yum install mysql-server, which is no more supported and for that I have to install mysql repo rpm first. i will write that some other time,
login to centos7 box with root and disable the firewall and flush iptables and disable iptables.
It is strongly not recommended that you stop firewall and iptables, I am just doing for my test purposes. you MUST configure firewall and iptables to allow MySQL incoming connection.
systemctl stop firewalld systemctl disable firewalld iptables -F service iptables save mysql-uroot -p 'YOUR_MYSQL_ROOT_PASSWORD' MYSQL>CREATE USER 'root'@'%' IDENTIFIED BY 'Cro@t!a'; MYSQL>GRANT ALL ON *.* TO 'root'@'%' WITH GRANT OPTION; MYSQL>flush privileges;
