Elasticbeanstalk with MySQL (deploying Django app)

1

Having a bit of a mare trying to deploy my Django app to Elasticbeanstalk AWS

I'm getting issues related to the installation of mysql. See log files:

My Python pip requirements file is:

beautifulsoup4==4.12.3

and I've also specified the SQL flags in an addition .config file in the .ebextensions folder

option_settings:
  aws:elasticbeanstalk:application:environment:
    MYSQLCLIENT_CFLAGS: "-I/usr/include/mysql"
    MYSQLCLIENT_LDFLAGS: "-L/usr/lib64/mysql"

as well as yum package installation files in another:

packages:  
  yum:
    python3-devel: []
    mariadb-devel.x86_64: []
    mariadb.x86_64: []
    gcc: []

Here is an example .ebextensions/mysqlclient.config file that installs the necessary packages:

packages:
  yum:
    mysql-devel: []
  # Uncomment the following lines if you are using a Debian-based distribution
  # apt:
  #   libmysqlclient-dev: []
commands:
  set_mysqlclient_env:
    command: |
      echo "export MYSQLCLIENT_CFLAGS=$(mysql_config --cflags)" >> /opt/elasticbeanstalk/hooks/appdeploy/pre/00_set_mysqlclient_env.sh
      echo "export MYSQLCLIENT_LDFLAGS=$(mysql_config --libs)" >> /opt/elasticbeanstalk/hooks/appdeploy/pre/00_set_mysqlclient_env.sh

Sets the MYSQLCLIENT_CFLAGS and MYSQLCLIENT_LDFLAGS environment variables using the output of mysql_config, which provides the compiler options needed to compile the client.

  • As far as my research goes, only mariadb-devel.x86_64 and mariadb.x86_64 are available on the yum package list for this environment (which contain mysql) -> See list of mysql yum packages above

  • try to add this after your mariadb installation

    commands: set_mysqlclient_env: command: | echo "export MYSQLCLIENT_CFLAGS=$(mysql_config --cflags)" >> /opt/elasticbeanstalk/hooks/appdeploy/pre/00_set_mysqlclient_env.sh echo "export MYSQLCLIENT_LDFLAGS=$(mysql_config --libs)" >> /opt/elasticbeanstalk/hooks/appdeploy/pre/00_set_mysqlclient_env.sh

  • Same error unfortunately. I have noticed that if I ssh into my instance the environmental varaibles for the sql flags are empty.
