1. 安装MySql Server
在/etc/yum.repos.d/目录下添加以下文件mysql-community.repo文件，内容如下：
[mysql56-community] name=MySQL 5.6 Community Server baseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/5/$basearch/ enabled=1 gpgcheck=0
执行yum install mysql-community-server即可。
启动服务 # service mysqld start
2 .设置密码
[root@yl-web yl]# mysql -u root
Welcome to the MySQL monitor. Commands end with ; or \g.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql> set password for 'root'@'localhost' =password('password');
3. 远程连接设置
把在所有数据库的所有表的所有权限赋值给位于所有IP地址的root用户。
mysql> grant all privileges on *.* to root@'%'identified by 'password';
如果是新用户而不是root，则要先新建用户
mysql>create user 'username'@'%' identified by 'password';
4 .将firewall关闭：
[root@gradven ~]# systemctl stop firewalld.service #停止firewall
[root@gradven ~]# systemctl disable firewalld.service #禁止firewall开机启动
最后reboot电脑
此时就可以进行远程连接了。
