How Can Run Phpmyadmin, Mysql and Apache Tomcat with Docker-Compose File? - docker

Question

I am trying to run java web app. Thus, I must setup MySQL, phpmyadmin and Apache Tomcat for accessing website. I want to use the docker and its docker-compose application to make installation easier (If I may learn).
I could not set mysql and phpmyadmin applications to work together. If I can get past this first step, I will try to install tomcat.
This is my codes which is used(docker-compose.yml)
version: '2'
services:
db:
image: mysql
restart: always
ports:
- "3306:3306"
environment:
MYSQL_DATABASE: myDb
MYSQL_USER: admin
MYSQL_PASSWORD: 12345
MYSQL_ROOT_PASSWORD: root
phpmyadmin:
image: phpmyadmin/phpmyadmin
restart: always
ports:
- "8080:80"
environment:
MYSQL_USER: admin
MYSQL_PASSWORD: 12345
MYSQL_ROOT_PASSWORD: root
depends_on:
- db
links:
- db
I open the above codes with docker-compose up in the command line application.
I'm going to http://localhost:8080/ page, I'm typing admin for Username, 12345 for password.
The errors I get are:
Cannot log in to MySQL server
mysqli_real_connect (): The server requested authentication method
mysqli_real_connect (): (HY000 / 2054): The server requested authentication method
How can I install the applications (mysql, phpmyadmin, tomcat) with docker-compose?

Answer 1

Currently phpmyadmin and MySQL can work together. It is solved.
PLAN A:
This is my docker-compose.yml file:
version: '2'
services:
db:
container_name: db
image: mysql
restart: always
ports:
- "3306:3306"
environment:
MYSQL_DATABASE: myDb
MYSQL_USER: admin
MYSQL_PASSWORD: 12345
MYSQL_ROOT_PASSWORD: root
command: --default-authentication-plugin=mysql_native_password
phpmyadmin:
depends_on:
- db
container_name: phpmyadmin
image: phpmyadmin/phpmyadmin
restart: always
ports:
- "8080:80"
environment:
MYSQL_USER: admin
MYSQL_PASSWORD: 12345
MYSQL_ROOT_PASSWORD: root
PMA_HOST: db
Now, you can go into MySQL via phpmyadmin at http://localhost:8080
It can also be solved by this method.
PLAN B: This is my docker-compose.yml file:
version: '2'
services:
db:
container_name: db
image: mysql
restart: always
ports:
- "3306:3306"
environment:
MYSQL_DATABASE: myDb
MYSQL_USER: admin
MYSQL_PASSWORD: 12345
MYSQL_ROOT_PASSWORD: root
phpmyadmin:
depends_on:
- db
container_name: phpmyadmin
image: phpmyadmin/phpmyadmin
restart: always
ports:
- "8080:80"
environment:
MYSQL_USER: admin
MYSQL_PASSWORD: 12345
MYSQL_ROOT_PASSWORD: root
PMA_HOST: db
Command line's commands:
$ docker stop phpmyadmin
$ docker exec -it db bash
$ mysql -u root -proot
$ ALTER USER root IDENTIFIED WITH mysql_native_password BY 'root';
$ exit
$ exit
$ docker start phpmyadmin
Now, you can go into MySQL via phpmyadmin at http://localhost:8080
Reference: phpMyAdmin on MySQL 8.0
