Are you looking MariaDB 5.5/10.0/10.1 Install guide?

MySQL is a relational database management system (RDBMS) that runs as a server providing multi-user access to a number of databases. This is guide, howto install or upgrade MySQL Community Server latest version 5.7 (5.7.13) on Fedora 24/23/22, CentOS 7.2/6.8/5.11 and Red Hat (RHEL) 7.2/6.8/5.11. This guide works of course with Oracle Linux and Scientific Linux too and MySQL 5.6/5.5 installation is possible too.

Note: If you are upgrading MySQL (from earlier version), then make sure that you backup (dump and copy) your database and configs. And remember run mysql_upgrade command.

  1. Hi,

    I’ve followed the procedure above an at point 6 I run into problems. How can I change the root password to something that MySQL accept? ( I give a 10 letter password below with Capitals and numbers in it)

    # /usr/bin/mysql_secure_installation

    Securing the MySQL server deployment.

    Connecting to MySQL server using password in ‘/root/.mysql_secret’
    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) : y

    New password:

    Re-enter new password:

    Estimated strength of the password: 50
    Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : Y
    … Failed! Error: Your password does not satisfy the current policy requirements

    • Hi Thommy,

      Following is from MySQL docs:

      The three levels of password checking are LOW, MEDIUM, and STRONG. The default is MEDIUM; to change this, modify the value of validate_password_policy. The policies implement increasingly strict password tests. The following descriptions refer to default parameter values; these can be modified by changing the appropriate system variables.

      LOW policy tests password length only. Passwords must be at least 8 characters long.

      MEDIUM policy adds the conditions that passwords must contain at least 1 numeric character, 1 lowercase and uppercase character, and 1 special (nonalphanumeric) character.

      STRONG policy adds the condition that password substrings of length 4 or longer must not match words in the dictionary file, if one has been specified.

      Default level is MEDIUM, so you need at least 1 numeric character, 1 lowercase and uppercase character, and 1 special (nonalphanumeric) character. Alternatively you can change it to LOW, then at least 8 characters long password should be okay.

      Or you can disable it using:

      • Thanks JR, that did the trick. Can’t see how I missed the special character. Got to get some sleep maybe …
