Hello guys,

I have successfully installed frappe framework but while creating new website it not connecting to maria db server. I have reinstalled but it is again showing the same error. Any help will be appreciated
thanks!

  1. Is mariadb installed and running? check with sudo service mysql status
    if its not running, try starting it manually: sudo service mysql start
  2. are you able to directly access it using the password you set? I think u access with: mysql -u root -p then enter your password

All this is done on the command line.

I have tried sudo service mysql status and it shows

Jun 07 14:43:24 seetech-VirtualBox systemd[1]: Failed to start MariaDB 10.3.29 database server.

and after running sudo service mysql start it showed
Job for mariadb.service failed because the control process exited with error code.
See “systemctl status mariadb.service” and “journalctl -xe” for details.

and yes im able to access it by my password i have set

4

mysql -u root -p
should able to get access even key in wrong password

how about
mysql -u root -h 127.0.0.1 -p
?

5

It’s still showing Can’t connect to MySQL server on ‘127.0.0.1’

This is exactly the same error even i am getting. Let me know if works.

that’s why the command test should refer what you facing.

add back 127.0.0.1 to the mariadb tables and grant to root
but this is not my prefer way

I will prefer add additional db, db_creator and db_password with grant right option to 127.0.0.1 host, or even % and localhost for some distribution.

those method only base on manual install, I not sure is that work on install script, since I haven’t test yet

General this line should work:
GRANT ALL PRIVILEGES ON . TO ‘DB_CREATOR’@‘127.0.0.1’ IDENTIFIED BY ‘DB_PASSWORD’ WITH GRANT OPTION;

for some case 127.0.0.1 not work:
GRANT ALL PRIVILEGES ON . TO ‘DB_CREATOR’@‘%’ IDENTIFIED BY ‘DB_PASSWORD’ WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON . TO ‘DB_CREATOR’@‘localhost’ IDENTIFIED BY ‘DB_PASSWORD’ WITH GRANT OPTION;

flush privileges;

change the variable to your value for “DB_CREATOR”, “DB_PASSWORD”

then create site with appropriate option that allow point to DB_CREATOR and DB_PASSWORD that you just create

Hi Atif,

Please replace Sammy with database name, replace % with 127.0.0.1, and MariaDB password with your MariaDB password.

GRANT ALL PRIVILEGES ON . TO ‘mydb’@‘127.0.0.1’ IDENTIFIED BY ‘12345’ WITH GRANT OPTION;

for the second problem

and then

FLUSH PRIVILEGES;

connect to 127.0.0.1 mysql server

You would be able to connect mysql server.

Thank you

I tried this but now it is showing "Access denied for user ‘root’@‘localhost’
and i have used GRANT ALL PRIVILEGES ON . TO ‘mydb’@‘%’ IDENTIFIED BY ‘mypass’;

11

I have tried it by it is showing "Access denied for user ‘root’@‘localhost’

12

Failed to start MariaDB 10.3.29 database server.

Check logs to see why the DB hasn’t started. After that

GRANT ALL PRIVILEGES ON *.* TO "root"@"localhost" IDENTIFIED BY "mypass" WITH GRANT OPTION";
