3. 进行MySQL 初始安全设置 设置（修改）root密码 删除匿名用户 禁用root远程登录 删除测试数据库test 重载权限表要启用MySQL 安全设置请输入以下命令/usr/bin/mysql_secure_installation
输出
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MySQL to secure it, we\'ll need the current password for the root user. If you\'ve just installed MySQL, and you haven\'t set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MySQL root user without the proper authorisation. Set root password? [Y/n] Y New password: Re-enter new password: Password updated successfully! Reloading privilege tables.. ... Success! By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n] Y ... Success! Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] Y ... Success! By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? [Y/n] Y - Dropping test database... ... Success! - Removing privileges on test database... ... Success! Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? [Y/n] Y ... Success! Cleaning up... All done! If you\'ve completed all of the above steps, your MySQL installation should now be secure. Thanks for using MySQL!【注】：如果您不想启动MySQL 安全设置命令，但至少也得修改一下root用户密码
mysqladmin -u root password [your_password_here] ## 示例## mysqladmin -u root password myownsecrectpass
4. 配置防火墙开启3306端口
修改/etc/sysconfig/iptables 文件:
vi /etc/sysconfig/iptables2. 在COMMIT之前加入以下内容:
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
3. 重启Iptables:
service iptables restart ## OR ## /etc/init.d/iptables restart
