Ubuntu 18.04 start mysql without root privilege

Question

I just installed ubuntu 18.04 and installed LAMP on it, however I had trouble using mysql without the root privilege. when I write:

mysql -u root -p

and enter the password I configured it throws access denied. unless if I write

sudo mysql -u root -p

and enter the password that I'm able to connect. But I don't want the sudo cause it prevents having workbench to connect to mysql, same applies to phpmyadmin too. Any hints on how to fix that?

Solution 1

It should only be the "-u root" user that requires sudo. It's good practice to not use root for most access anyways, so just login as root using sudo and create a newuser:

CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'password';

GRANT ALL PRIVILEGES ON database_name.* TO 'newuser'@'localhost';

Then you should be able to access "mysql -u newuser" without sudo.

I also faced this problem yesterday. To solve this problem follow these steps:

1. Connect to MySQL: sudo mysql -u root
2. Check for mysql users in db: SELECT User,Host FROM mysql.user;
3. Drop root user account: DROP USER 'root'@'localhost';
4. Recreate root user: CREATE USER 'root'@'%' IDENTIFIED BY ''
5. Grant all privileges to root user: GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
6. Set password for root user: ALTER USER 'root'@'%' IDENTIFIED BY 'yourpassword';

That's it! Now you should be able to connect the MySQL.

Solution 3

enter image description here 1. UPDATE mysql.user SET plugin = 'mysql_native_password' WHERE user = 'root' AND plugin = 'unix_socket';

2.FLUSH PRIVILEGES;

Solution 4

I am using Ubuntu 18.04 with mysql version 5.7 in workbench but solved this by following these 10 steps

1. Connect to MySQL: sudo mysql -u root
2. Check for mysql users in db: SELECT User,Host FROM mysql.user;
3. Drop root user account: DROP USER 'root'@'localhost';
4. SET GLOBAL validate_password_length = 5;
5. SET GLOBAL validate_password_number_count = 0;
6. SET GLOBAL validate_password_mixed_case_count = 0;
7. SET GLOBAL validate_password_special_char_count = 0;
8. SET GLOBAL validate_password_policy = LOW;
9. Recreate root user: CREATE USER 'root'@'%' IDENTIFIED BY 'admin'
10. Grant all privileges to root user: GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
