Reset MySQL root password on Bitnami server
To reset MySQL root password on Bitnami server, first check MySQL server version you are running.
mysql --version
Create a file
vi /tmp/mysql-init
Add following text
For MySQL 5.7 or MySQL 8
ALTER USER 'root'@'localhost' IDENTIFIED BY 'NEW_PASSWORD'; ALTER USER 'root'@'127.0.0.1' IDENTIFIED BY 'NEW_PASSWORD';
For MySQL 5.6
UPDATE mysql.user SET Password=PASSWORD('NEW_PASSWORD') WHERE User='root';
FLUSH PRIVILEGES;
In above code, replace NEW_PASSWORD with your new MySQL root password.
Stop MySQL
/opt/bitnami/ctlscript.sh stop mysql
Reset MySQL root password by running
MySQL 5.7/MySQL 8
/opt/bitnami/mysql/bin/mysqld_safe --pid-file=/opt/bitnami/mysql/data/mysqld.pid --datadir=/opt/bitnami/mysql/data --init-file=/tmp/mysql-init --lower_case_table_names=1 2> /dev/null &
If you are using MySQL 5.6 or older, run
/opt/bitnami/mysql/bin/mysqld_safe --pid-file=/opt/bitnami/mysql/data/mysqld.pid --datadir=/opt/bitnami/mysql/data --init-file=/tmp/mysql-init 2> /dev/null &
Restart MySQL
