![]() This would create a “super” user that would be able to do everything you can now. To do this, the GRANT statement would look like: GRANT ALL PRIVILEGES ON *.* TO ‘ user localhost ’ WITH GRANT OPTION You can also use a GRANT statement to give users full privileges over your MySQL server. If you wanted to limit them to a domain, you would change localhost to. If you want them to be able to gain access from anywhere, the hostname can be replaced by a ‘%’ wildcard. ![]() Keep in mind that users will only be able to access the database from the hostname provided in the GRANT statement. If you use this example to set permissions, be sure to replace thisDatabase with the name of your database and the with the user and its corresponding hostname. This specific example gives user at the localhost permission to access the database called thisDatabase. Here’s an example of a GRANT statement: GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP ON thisDatabase. GRANT statements essentially grant the user certain permissions. The key to adding permissions is using the GRANT statements. You can determine what user accesses what, which keeps the database secure and the lessens the risk of one user causing widespread damage. Setting up permissions per user is helpful, especially when you have multiple people working on your databases. However, this is not recommended since opens up vulnerabilities in your MySQL server. You can also create a user without a password by using the formula: CREATE USER ‘ user localhost ’ Replace password with a password for the new user. However, if you replace localhost with a ‘%’ (commonly referred to as a wildcard), this user will be able to log in from any host. The user will only be able to log in from the hostname listed. Replace user with the name you want to identify the new user. To create users, you can use the following formula: CREATE USER ‘ user localhost ’ IDENTIFIED BY ‘ password ’ This gives you the permissions you need to create and manage users. Once you have reached the location of your MySQL, you can login to root by inputting: mysql -user=root mysql Follow your web host’s instructions to establish the connection. Note that if your MySQL databases are on a server, you will first need to connect to the server via the command line. To create a user in MySQL, you need to first log in to the MySQL server as the root user. As the administrator, you can edit their permissions at any time to better fit your needs. You can also limit their access by giving their account specific permissions. You can then delete their account if they no longer need access. If you want to give people access to work on your database, your best course of action is to create an account for them to log in on their own.
