Docker phpmyadmin ignoring my php.ini config

Question

I build up a docker-compose environment with apache, php7.0, mysql and also added phpmyadmin.

I tried so many times to include my own php.ini file and finally, I got to php accept it as it shown in my index.php loaded with phpinfo().

I need to load a database that weights more than 750Mb and my phpmyadmin doesn't let me import databases larger than 512Mb.

I tried to compress the db to 60Mb, but when I try to import it, it takes so long and ends up cutting the import because it took so long, leaving my db incomplete.

Even setting up my php.ini file_size limits and all that, the phpmyadmin ignores it.

This is what I've changed in php.ini:

upload_max_filesize = 1024M
post_max_size = 1024M
memory_limit = 1024M
max_execution_time = 300

My docker-compose.yml is:

version: '3.3'

services:
  php:
    build: apache-php
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - ./apache-php/www:/var/www/html
    links:
      - mysql
      - phpmyadmin

  mysql:
    image: mysql:5.7
    volumes:
     - ./mysql:/var/lib/mysql
    environment:
     - MYSQL_ROOT_PASSWORD=1347891743
     - MYSQL_DATABASE=database

  phpmyadmin:
    image: phpmyadmin/phpmyadmin
    links:
      - mysql
    environment:
      PMA_HOST: mysql
      PMA_PORT: 3306
    ports:
      - "8080:80"
    volumes:
      - ./mysql:/var/lib/mysql

I also got a Dockerfile to run my php:

FROM php:7.0-apache

RUN docker-php-ext-install mysqli


COPY config/php.ini /usr/local/etc/php/

This is what it shows in phpmyadmin.

A little of help would be very appreciated

Answer 1

You can try:

Config of php.ini in phpmyadmin container in /usr/local/etc/php/

This is in .yml

phpmyadmin:
    volumes:
        - ./php-make/upload.ini:/usr/local/etc/php/php.ini

And file upload.ini

upload_max_filesize = 1280M
post_max_size = 1280M

Change any point if you want

I can do and success

Answer 2

Try this: access your phpmyadmin docker container: docker exec -it [container name or is] bash

create a php.ini in /usr/local/etc/php:

 nano /usr/local/etc/php/php.ini

(nano or vi, depends in the editor you prefer)

Add the lines you need, as example:

file_uploads = On
memory_limit = 6G
upload_max_filesize = 6G
post_max_size = 6G
max_execution_time = 6000

then reload: service apache2 reload

That worked for me!!

From my experience PhpMyAdmin is not the best way to import big databases. So even if you'll manage to increase memory_limit you'll still encounter long process time.

It would be better to provide init script and link it to /docker-entrypoint-initdb.d folder via docker-compose. For example:

mysql:
image: mysql:5.7
volumes:
 - ./my_directory_with_init_scripts:/docker-entrypoint-initdb.d
 - ./mysql:/var/lib/mysql
environment:
 - MYSQL_ROOT_PASSWORD=1347891743
 - MYSQL_DATABASE=database

From here you may see that it scans /docker-entrypoint-initdb.d folder for sutable file (including *.sql) and processes them. So just put your SQL dump file in linked volume and it's done.

If you still need to increase php memory_limit, then probably you can set PMA specific settings using /etc/phpmyadmin/config.user.inc.php. More information in PMA docs and in PMA docker image readme .

Answer 4

The easy way is use the environment vars.

Inside the phpmyadmin container if you check the php conf files you can see find the file /usr/local/etc/php/conf.d/phpmyadmin-misc.ini

with this content:

allow_url_fopen=Off
max_execution_time=${MAX_EXECUTION_TIME}
max_input_vars=10000
memory_limit=${MEMORY_LIMIT}
post_max_size=${UPLOAD_LIMIT}
upload_max_filesize=${UPLOAD_LIMIT}

So you can override that value simply use environment

Your docker-composer.yml become

version: '3.3'

services:
  php:
    build: apache-php
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - ./apache-php/www:/var/www/html
    links:
      - mysql
      - phpmyadmin

  mysql:
    image: mysql:5.7
    volumes:
     - ./mysql:/var/lib/mysql
    environment:
     - MYSQL_ROOT_PASSWORD=1347891743
     - MYSQL_DATABASE=database

  phpmyadmin:
    image: phpmyadmin/phpmyadmin
    links:
      - mysql
    environment:
      - PMA_HOST=mysql
      - PMA_PORT=3306
      - UPLOAD_LIMIT=1024M
      - MEMORY_LIMIT=1024M
      - MAX_EXECUTION_TIME=300
    ports:
      - "8080:80"
    volumes:
      - ./mysql:/var/lib/mysql

is the same running the docker command:

docker run -e VARIABLE=VALUE ...

Answer 5

You can config file "phpmyadmin-misc.ini" in docker container

1. Check merged directory.

• docker inspect phpmyadmin

  "MergedDir": "/var/lib/docker/overlay2/e703e63ddf58c0decebd292eabaf8fe2c7eef49eafa390d7f7cc971f523fb0a8/merged",

2. Edit file

   • cd var/lib/docker/overlay2/e703e63ddf58c0decebd292eabaf8fe2c7eef49eafa390d7f7cc971f523fb0a8/merged
   • vi usr/local/etc/php/conf.d/phpmyadmin-misc.ini

Add 2 lines

upload_max_filesize = 1024M
post_max_size = 1024M

3. Restart Docker container

• docker restart phpmyadmin

Answer 6

You can pass the UPLOAD_LIMIT parameter into your docker run command. The phpMyAdmin container sets the default to 2mb.

You can check it on the official documentation: https://hub.docker.com/_/phpmyadmin
