installation normale

systemctl stop apache2 && apt-get install phpmyadmin && systemctl start apache2 && a2enconf phpmyadmin && systemctl reload apache2 && systemctl stop apache2 && systemctl start apache2

marche pour trixie/deb13, on obtient ce fichier /etc/apache2/conf-available/phpmyadmin.conf :

changer le mot de passe root du mysql/mariadb

mettre un nouveau mot de passe : solution 2024/bookworm

Parfois, il est impossible de changer correctement le mot de passe comme indiqué en dessous ; une solution : nettoyer la table user

service mariadb stop ; service mysql stop ; service mysqld stop ; /etc/init.d/mysql stop ; /etc/init.d/mysqld stop service mariadb start ; service mysql start ; service mysqld start ; /etc/init.d/mysql start ; /etc/init.d/mysqld start mysql -u root use mysql; select * from user; truncate table user; flush privileges; grant all privileges on *.* to root@localhost identified by 'Motdepasse' with grant option; flush privileges; quit; service mysql stop ; service mysqld stop ; /etc/init.d/mysql stop ; /etc/init.d/mysqld stop service mysql start ; service mysqld start ; /etc/init.d/mysql start ; /etc/init.d/mysqld start

mettre un nouveau mot de passe : solution 2023/bullseye

service mysql stop ; service mysqld stop ; /etc/init.d/mysql stop ; /etc/init.d/mysqld stop service mysql start ; service mysqld start ; /etc/init.d/mysql start ; /etc/init.d/mysqld start mysql -u root ALTER USER 'root'@'localhost' IDENTIFIED BY 'Nouveau motdepasse'; flush privileges ;

mettre un nouveau mot de passe

Arrêter le serveur mysql ( erreurs normales )

service mysql stop ; service mysqld stop ; /etc/init.d/mysql stop ; /etc/init.d/mysqld stop

Démarrer le serveur mysql sans mot de passe :

mysqld_safe --skip-grant-tables &

on se connecte à mysql :

mysql -u root

Dans mysql , on va 1)choisir la base de donnée mysql, 2)mettre à jour le mot de passe root puis 3)on intègre le mot de passe à mysql ; 4) on sort

use mysql; update user set password=PASSWORD("NEW-ROOT-PASSWORD") where User='root'; flush privileges; quit

on redémarre

service mysql start ; service mysqld start ; /etc/init.d/mysql start ; /etc/init.d/mysqld start

test : mot de passe changé et accepté

mysql -u root doit donner
ERROR 1045 (28000) : Access denied for user 'root'@'localhost' (using password : NO)

mot de passe changé mais non accepté

Parfois le mot de passe est bon mais tout est comme si le mot de passe n'était pas accepté :
solution rapide : sur debian l'option 1 marche,donc

$ sudo mysql -u root # I had to use "sudo" since is new installation mysql> USE mysql; UPDATE user SET plugin='mysql_native_password' WHERE User='root'; FLUSH PRIVILEGES; exit;

https://stackoverflow.com/questions/39281594/error-1698-28000-access-denied-for-user-rootlocalhost :
Some systems like Ubuntu, mysql is using by default the UNIX auth_socket plugin.

Basically means that : db_users using it, will be "auth" by the system user credentias. You can see if your root user is set up like this by doing the following :

non essayé : mysqladmin -u root -p"mdp_root" password "nouveau_mdp";

recherche de solution

mysql -u root mysql> USE mysql; SELECT User, Host, plugin FROM mysql.user;

User	plugin
root	unix_socket ( ou auth_socket )
mysql.sys	mysql_native_password
debian-sys-maint	mysql_native_password

As you can see in the query, the root user is using the auth_socket plugin

There are 2 ways to solve this :

You can set the root user to use the mysql_native_password plugin
You can create a new db_user with you system_user (recommended)

Option 1 :

mysql -u root mysql> USE mysql; UPDATE user SET plugin='unix_socket' WHERE User='root'; FLUSH PRIVILEGES; exit; service mysql restart

Option 2 : (replace YOUR_SYSTEM_USER with the username you have)

mysql -u root mysql> USE mysql; CREATE USER 'YOUR_SYSTEM_USER'@'localhost' IDENTIFIED BY ''; GRANT ALL PRIVILEGES ON *.* TO 'YOUR_SYSTEM_USER'@'localhost'; UPDATE user SET plugin='unix_socket' WHERE User='YOUR_SYSTEM_USER'; FLUSH PRIVILEGES; exit; service mysql restart

Remember that if you use option #2 you'll have to connect to mysql as your system username (mysql -u YOUR_SYSTEM_USER)

Note : On some systems (e.g., Debian stretch) 'auth_socket' plugin is called 'unix_socket', so the corresponding SQL command should be : UPDATE user SET plugin='unix_socket' WHERE User='YOUR_SYSTEM_USER';
