5.11 MySQL security initialization (optional)

[root@node7 system]# mysql_secure_installation Securing the MySQL server deployment. Enter password for user root: #Here, enter the password generated during MySQL initialization (grep 'temporary password' /data/log/mysql_error.log ) The existing password for the user account root has expired. Please set a new password. New password: #Enter new password Re-enter new password: VALIDATE PASSWORD PLUGIN can be used to test passwords and improve security. It checks the strength of password and allows the users to set only those passwords which are secure enough. Would you like to setup VALIDATE PASSWORD plugin? Press y|Y for Yes, any other key for No: n #y install MySQL password plug-in Using existing password for root. Change the password for root ? ((Press y|Y for Yes, any other key for No) : n ... skipping. 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) : y #y remove anonymous users 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) : n #Allow root remote login ... 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) : y #Remove test database or not - 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) : y #Refresh permission table Success. All done!

5.12 modify the password and give the user permission (according to his own situation)

Since then, the RPM installation of MySQL has been completed. This method automatically generates / etc/my.cnf , check the configuration file to know the log directory and data directory of MySQL.

7.4 modify the root password of MySQL and give the user permission

If you want to set a simple password like 123456, you can execute it in SQL: #mysql> set global validate_password_policy=0; #mysql> set global validate_password_length=1; #In this way, SET PASSWORD = PASSWORD('123456 ') can be executed again successfully.

When authority 1, authority 2 Permission n is replaced by all privileges or all, which means that all permissions are given to the user. When the database name.

You can also connect from any address with a '%'. 'connection password' cannot be empty, otherwise creation fails.

7.5 uninstall Yum Repository

#Since Yum Repository is installed, every yum operation will be updated automatically.
