![]() service mysqld stop yum remove mysql -y yum remove mysql-server -y and then lets re-install it. ![]() Before you begin All commands are executed as an administrative user (the minimum privilege required to delete a database is DROP) or with a root account. This tutorial describes how to delete (or drop) a MySQL or MariaDB database through the command line. replace matomo by your chosen MySQL username (or simply use matomo). lets remove mysql completely from centos. MySQL is the most popular open-source relational database management system.replace my-strong-password-here by a strong secure password.replace matomo_db_name_here with the name of your MySQL database (if possible, this database should only have the Matomo tables installed).Sometimes it is not enough to kill each process manually. ![]() ![]() Grant this user matomo the permission to access your matomo_db_name_here database $ mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, INDEX, DROP, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES ON matomo_db_name_here.* TO is important to grant the user the following privileges: SELECT, INSERT, UPDATE, DELETE, CREATE, INDEX, DROP, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES Or if you are using an older version such as MySQL 5.1, MySQL 5.5, MySQL 5.6: $ mysql> CREATE USER IDENTIFIED BY 'my-strong-password-here' If you are installing Matomo (Piwik) on your own server and/or donât have a tool available to manage your database, you can manually create the MySQL database user by following these steps:Ĭreate a database for Matomo: $ mysql> CREATE DATABASE matomo_db_name_here Ĭreate a user called matomo, if you are using MySQL 5.7 or MySQL 8 or newer: $ mysql> CREATE USER IDENTIFIED WITH mysql_native_password BY 'my-strong-password-here' To create your database and database user, you would typically use your web hosting provider interface which would let you add a new MySQL database and create a new user with permission to access this database, in just a few clicks. ConclusionĪdd and delete users on centOS 8 Through this tutorial, we have learned how to add and delete users on CentOS 8.When installing Matomo you need to specify a MySQL (or MariaDB) database hostname, user and password. If the user has sudo capabilities, he or she will be removed from the wheel group, as well as any other groups to which the user belongs. The userdel command produces no output when it succeeds. The -r flag is used to destroy the userâs home directory and mail spool: sudo userdel -r username Run the following command to deactivate the user without removing the userâs files: sudo userdel username We can delete the user account using the deluser command-line utility if it is no longer required. If we are logged in as root, we donât have to prepend each command with sudo. Sudo access is allowed to members of the group wheel by default on CentOS.Īdd the newly created user to the wheel group if we want them to have administrative rights: sudo usermod -aG wheel username Passwd: all authentication tokens updated successfully. Weâll be asked to type in and confirm password. Use the passwd command to do so: sudo passwd username The user can write, edit, and delete files and folders in their home directory.Īfter that, weâll need to provide the new user a password so that they may log in. It will construct the new userâs home directory ( /home/username) and copy files from the /etc/skel directory to it. There is no output from the command above. We would run the following commands to create a new user account named âusernameâ: sudo adduser username The useradd command-line utility in CentOS can be used to establish a new user account.
