阿里云CentOS-7.2安装mysql

第一步,追加MySQL 5.6版本的源

rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

第二步,安装

yum -y install mysql-community-server

第三步,设置MySQL开机启动

systemctl enable mysqld

第四步,启动MySQL

systemctl start mysqld

第五步,重置root密码

mysql_secure_installation

这一步时,会有几步关键选择:

[root@izuf6hnnkl1li29kw2nc39z ~]# mysql_secure_installation //输入这里

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):  //这里会询问键入当前密码,由于是新安装,默认密码空,我们直接回车

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      询问设置root密码,键入y

New password:                         输入新的root密码

Re-enter new password:             确认新密码

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    询问是否移除匿名用户,我们输入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] n     询问是的允许远程登录,我们输入n

 ... skipping!

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  询问是否删除测试数据库test,我们选择y

 - Dropping test database...

ERROR 1008 (HY000) at line 1: Can't drop database 'test'; database doesn't exist

 ... Failed!  Not critical, keep moving...

 - 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   询问是否刷新权限,我们输入y

 ... Success!

All done!  If you've completed all of the above steps, your MySQL installation should now be secure.

Thanks for using MySQL!

Cleaning up...
