Navigating phpMyAdmin's Compatibility with MySQL 8.0
In the realm of database management, phpMyAdmin remains a sought-after tool. However, as MySQL progresses to its latest version, 8.0, users may encounter connectivity hurdles with phpMyAdmin.
Error Encountered:
When attempting to access phpMyAdmin, users often face the following error:
#2054 - The server requested authentication method unknown to the client
This error stems from the enhanced security measures employed in MySQL 8.0, which introduce a stronger password hashing mechanism.
Solution:
To resolve this issue, you must alter the authentication method specified for the root user within the MySQL instance:
root@9532f0da1a2a:/# mysql -u root -pPASSWORD
mysql> ALTER USER root IDENTIFIED WITH mysql_native_password BY 'PASSWORD';
By setting the authentication plugin to 'mysql_native_password,' you enable compatibility with phpMyAdmin.
Docker Environment Solution:
For those utilizing Docker containers:
docker run --name mysql -e MYSQL_ROOT_PASSWORD=PASSWORD -p 3306:3306 -d mysql:latest docker exec -it mysql bash mysql -u root -pPASSWORD ALTER USER root IDENTIFIED WITH mysql_native_password BY 'PASSWORD'; exit exit docker run --name phpmyadmin -d --link mysql:db -p 8080:80 phpmyadmin/phpmyadmin:latest
Additional Considerations:
mysql/mysql-server docker image:
For this docker image, simply uncomment the following line in /etc/my.cnf:
# default-authentication-plugin=mysql_native_password
Alternatively, the following workaround commands can be used:
docker run --name mysql -e MYSQL_ROOT_PASSWORD=PASSWORD -e MYSQL_ROOT_HOST=% -p 3306:3306 -d mysql/mysql-server:latest docker exec -it mysql sed -i -e 's/# default-authentication-plugin=mysql_native_password/default-authentication-plugin=mysql_native_password/g' /etc/my.cnf docker stop mysql; docker start mysql docker run --name phpmyadmin -d --link mysql:db -p 8080:80 phpmyadmin/phpmyadmin:latest
default_authentication_plugin:
Updated solution (09/13/2021):
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
