Wordpress: Wordpress latest does not works with mysql latest container

[shubhamrajvanshi]

Wordpress latest does not works with mysql latest container.
I get below error in wordpress container logs.

Warning: mysqli::__construct(): (HY000/2054): The server requested authentication method unknown to the client in Standard input code on line 22

MySQL Connection Error: (2054) The server requested authentication method unknown to the client

MySQL Connection Error: (2054) The server requested authentication method unknown to the client

Warning: mysqli::__construct(): The server requested authentication method unknown to the client [caching_sha2_password] in Standard input code on line 22

[wglambert]

MySQL 8 changed the password authentication method. You're looking for the mysql_native_password plugin
https://dev.mysql.com/doc/refman/8.0/en/native-pluggable-authentication.html

So you'll want to connect with mysql --default-auth=mysql_native_password -p

Or you could use mysql 5.7

https://github.com/docker-library/mysql/issues/424#issuecomment-387403312

[shubhamrajvanshi]

Thanks @wglambert but how do I add this to my mysql image. I need to use public image and not self build one's

[yosifkit]

You just add it to the command (after the image on a docker run). Here is a docker compose:

version: '3.1'

services:

  wordpress:
    image: wordpress
    restart: always
    ports:
      - 8080:80
    environment:
      WORDPRESS_DB_PASSWORD: example

  mysql:
    image: mysql:5.7
# or
    image: mysql:8
    command: '--default-authentication-plugin=mysql_native_password'
# common options
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: example

[tianon]

(Closing, since this is an issue with usage, not with the image. In the future, these sorts of questions/requests would be more appropriately posted to the Docker Community Forums, the Docker Community Slack, or Stack Overflow.)

[shubhamrajvanshi]

@yosifkit I am not sure if I am right in here but wouldn't the command option fail in this case as it would override the original command in the image. I do see it's in quotes but wouldn't it become the command that was passed to it.

[shubhamrajvanshi]

@tianon The reason I opened it as an issue so as to address it in wordpress rather than passing an extra argument. I was hoping to have a more general solution in the wordpress image itself rather than disabling a nice security feature in mysql. Thoughts?

[tianon]

PHP itself doesn't support the new authentication type in MySQL 8, so even
if we wanted to patch WordPress to support it, we can't right now.

[yosifkit]

@shubhamrajvanshi it shouldn't fail, since we are not overriding the entrypoint. The command becomes the arguments to the entrypoint and when the entrypoint gets arguments that are only flags (-*) it assumes they are flags for mysqld and eventually launches it with those provided flags.

https://github.com/docker-library/mysql/blob/fc3e856313423dc2d6a8d74cfd6b678582090fc7/8.0/docker-entrypoint.sh#L6-L8

Which is why these work:

$ docker run -it --rm mysql:8 --version
/usr/sbin/mysqld  Ver 8.0.11 for Linux on x86_64 (MySQL Community Server - GPL)
$ docker run -it --rm mysql:8 --verbose --help --default-authentication-plugin=mysql_native_password | grep default-authentication-plugin
  --default-authentication-plugin=name 
default-authentication-plugin                                mysql_native_password

[songhanpoo]

MySQL 8 changed the password authentication method. You're looking for the mysql_native_password plugin
https://dev.mysql.com/doc/refman/8.0/en/native-pluggable-authentication.html

So you'll want to connect with mysql --default-auth=mysql_native_password -p

Or you could use mysql 5.7

Many thanks for suggest !

[siddjain]

this does not work for us. we still get same error even after using

command: '--default-authentication-plugin=mysql_native_password'

mysql logs show

@siddjain whats your wordpress version (exact image tag)?

[siddjain]

this is what we have

$ docker image ls

[bukowa]

@shubhamrajvanshi and others, this is beacuse latest wordpress uses:

env ENV PHP_VERSION=7.3.13
I think that you need PHP 7.4 for the caching_sha2_password to work.

See https://github.com/php/php-src/commit/4f06e67ad2201390ed35a9ea6288a00c0b04782b#commitcomment-36593173

It seems that prior to 7.4.2 there were still many bugs in that plugin.
Using https://hub.docker.com/layers/wordpress/library/wordpress/php7.4-fpm-alpine/images/sha256-0d48cbecd225d5ea6098daa6fa0c4e218fc90b87358ffc0ccd72cbc4b2bc0573 with
env ENV PHP_VERSION=7.4.1

I have no problems with mysql 8.x and caching_sha2_password

[siddjain]

I do see this in the log

[Wed Jan 22 21:38:46.387427 2020] [mpm_prefork:notice] [pid 1] AH00163: Apache/2.4.38 (Debian) PHP/7.3.13 configured -- resuming normal operations

however the point being debated is that the addition of --default-authentication-plugin=mysql_native_password should fix the problem which in our experience it doesn't.

[siddjain]

there is a new error though. first we have 2 containers:

$ docker ps
CONTAINER ID        IMAGE                         COMMAND                  CREATED             STATUS              PORTS                            NAMES

wordpress_db_1 is running mysql server.

wordpress_wordpress_1 is running WP.

now we see this in wp log

from container: wordpress_wordpress_1

MySQL Connection Error: (1045) Access denied for user 'wordpress'@'X.X.X.X' (using password: YES)

but we verified that one can login to the database as wordpress using the password we have
