Create database syntax mysql

  When creating the app database, you need to set the owner.

First, create the database.

mysql> create database appname;

then create the  user who will have write permissions:

mysql> create user 'appname'@'localhost' identified with mysql_native_password by 'somepassword';

or 

        mysql> create user 'appname'@'localhost' identified with caching_sha2_password by 'somepassword';

mysql> flush privileges;

If you forget the password, you can change it again like so:

mysql> alter user 'appname'@'localhost' identified with mysql_native_password by 'somepassword';

If you are using mysql version 8 or later, you need "with mysql_native_password" otherwise wordpress doesn't authenticate the database owner. At least, that was still true at the time of writing this.

If you are using mysql version 5 or below, you can skip that.

what to do if you crashed your database OR it says there are no tables (but there are!)

Sometimes moving a database file ( /var/lib/mysql/* ) breaks the records inside mysql's brain about what databases it had and what their tables were. If you did not use mysqldump to take backups, you are in trouble. Unfortunately if you do this, you have a long night ahead of you. However, help is at hand. A symptom of breaking Moodle in this way is you get this error:     Config table does not contain version, can not continue, sorry.     which means it cannot read the table mdl_config. The basic steps are: 1. Move your crashed/confused databases out the way so you don't break them further.  2. Recreate your mysql instance. 3. Recreate the databases and tables WITHOUT their contents (just the database names and table structures). 4. Tell mysql to forget their contents without using drop command (you use discard instead) 5. move your original db files back into place 6. Tell mysql to re-scan (import) the db files. 7. Create a timed script to run backups Here are...

completely erase and reinstall mysql script.

 Warning: this will delete ALL your databases. After running this script it will let you automatically run mysql without a password (as root). Note this  is a security risk so do not run this on a production server. #!/bin/bash set -e # Function to remove MySQL and clean up remove_mysql() {     echo "Removing MySQL server and packages..."     sudo apt-get remove -y mysql-server mysql-client mysql-common     echo "Removing MySQL directories..."     sudo rm -rf /etc/mysql /var/lib/mysql /var/log/mysql /var/run/mysqld     # Clean up any residual packages and update package info     sudo apt-get autoremove -y     sudo apt-get clean } # Function to ensure MySQL configuration file exists ensure_mysql_config() {     if [ ! -f /etc/mysql/mysql.cnf ]; then         echo "Creating MySQL configuration file..."         echo "[client]" | sudo tee /etc/mysql/mysql.cnf ...

mysql says you can't login as root but you have definitely got the right password

If mysql says you can't login as root but you have definitely got the right password and you have just installed it for the first time, it can be a nuisance. Do the below as user root. My suggestion is: 1. If you have existing databases, and want to keep them, back them up with mysqldump.       mysqldump -u user_with_access -pPassword database_to_rescue > database_to_rescue.sql Assuming that you have at least one user account, e.g. "user_with_access", who can read the database called “database_to_rescue". 2. Erase the mysql directory and start over:       service mysql stop rm -rf /var/lib/mysql/* 3. Re-run mysqld initialisation to set the password to blank: mkdir -p /var/run/mysqld chown -R /var/run/mysqld chmod 777 /var/run/mysqld # you can change this back to 755 later mysqld --initialize-insecure --user=mysql If it says it can't find the socket in /var/run/mysqld, repeat the commands mkdir-chown above. 4. It will then set up mysql from scratch w...
