Command "sudo service mysql" status is showing "exited" instead of running


I was trying to change the MySQL root password and I don’t know whats wrong I did.

I am getting below error.

Log :point_down:

Then I searched for this issue and tried many solutions but no luck.

Now, after adding a line “innodb_force_recovery = 2” to file “/etc/mysql/mysql.conf.d/mysqld.cnf”

how can I start mysql whithout losing data?
