增加用户，用于远程访问

mysql> create user [email protected]'%' identified by '123456';
Query OK, 0 rows affected (0.09 sec)

mysql> grant all privileges on *.* to [email protected]'%' with grant option;
Query OK, 0 rows affected (0.15 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.06 sec)

远程访问mysql，配置操作

/etc/sysconfig/下没有iptables的问题
1、停止并屏蔽firewalld服务
systemctl stop firewalld
systemctl mask firewalld
2、安装iptables-services软件包
yum install iptables-services
3、在引导时启用iptables服务
systemctl enable iptables
4、启动iptables服务
systemctl start iptables

vim /etc/sysconfig/iptables
-A INPUT -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT
systemctl restart iptables.service
centos 7 上配置mysql 开机启动详解
创建配置文件
touch /usr/lib/systemd/system/mysql.service
配置文件
[Unit]
Description=MySQL Server
Documentation=man:mysqld(8)
Documentation=http://dev.mysql.com/doc/refman/en/using-systemd.html

After=syslog.target

[Install]

通过systemctl来启动mysql
systemctl start mysql.service
ps -ef |grep mysql

通过systemctl 来设置mysql开机启动
systemctl enable mysql
