 vim /var/log/mysqld.log

收索 A temporary password is generated for root@localhost 

 Securing the MySQL server deployment. Enter password for user root: <–输入找到的初始密码 he existing password for the user account root has expired. Please set a new password. New password: <– 设置root用户的密码 Re-enter new password: <– 再输入一次你设置的密码 The 'validate_password' plugin is installed on the server. The subsequent steps will run with the existing configuration of the plugin. Using existing password for root. Estimated strength of the password: 100 Change the password for root ? ((Press y|Y for Yes, any other key for No) : <-是否更改root密码 New password:<– 再输入一次你设置的密码 Re-enter new password: <– 再输入一次你设置的密码 Estimated strength of the password: 100 Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : <-确认更改root密码 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? (Press y|Y for Yes, any other key for No) : <-删除匿名用户? 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? (Press y|Y for Yes, any other key for No) : <–是否禁止root远程登录,根据自己的需求选择Y/n并回车,建议禁止 ... 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? (Press y|Y for Yes, any other key for No) : <– 是否删除test数据库,直接回车 - 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? (Press y|Y for Yes, any other key for No) : <– 是否重新加载权限表，直接回车 Success. All done! 

3.登录数据库
