postgresql - 在 AWS Beanstalk 或 EC2 实例中使用 GeoDjango 支持设置 Django

Question

因此，我曾经使用 Amazon Instance (2013.09) ami-35792c5c 通过 Beanstalk 进行此操作。当时这个 ebextension 脚本放在 .ebextensions/中的 repo 的根目录下时效果很好

00_repo.config

packages:
    rpm:
        pgdg-redhat93-9.3-1: 'http://yum.postgresql.org/9.3/redhat/rhel-6-x86_64/pgdg-redhat93-9.3-1.noarch.rpm'
        remi: 'http://rpms.famillecollet.com/enterprise/remi-release-6.rpm'

files:
    "/etc/yum.repos.d/pgdg-93-redhat.repo":
        mode: "000644"
        owner: root
        group: root
        content: |
            [pgdg93]
            name=PostgreSQL 9.3 $releasever - $basearch
            baseurl=http://yum.postgresql.org/9.3/redhat/rhel-6-$basearch
            enabled=1
            gpgcheck=1
            gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-PGDG-93

            [pgdg93-source]
            name=PostgreSQL 9.3 $releasever - $basearch - Source
            failovermethod=priority
            baseurl=http://yum.postgresql.org/srpms/9.3/redhat/rhel-6-$basearch
            enabled=0
            gpgcheck=1
            gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-PGDG-93


commands:
    epel_repo:
        command: yum-config-manager -y --enable epel

    remi_repo:
        command: yum-config-manager -y --enable remi

01_app.config

packages:
    yum:
        libtiff-devel: ''
        libjpeg-devel: ''
        libzip-devel: ''
        freetype-devel: ''
        postgresql-devel: ''
        gdal: ''
        gdal-python: ''
        geos: ''
        proj: ''
        libmemcached: ''
        libmemcached-devel: ''
        cyrus-sasl-devel: ''
        zlib-devel: ''

container_commands:
    01_collectstatic:
        command: 'PYTHONPATH=.:..:../lib cd site/kpmkhv && ./manage.py collectstatic -c --noinput && cd ../..'
        leader_only: true
    02_syncdb:
        command: 'PYTHONPATH=.:..:../lib cd site/kpmkhv && ./manage.py syncdb --noinput && cd ../..'
        leader_only: true
    03_migrate:
        command: 'PYTHONPATH=.:..:../lib cd site/kpmkhv && ./manage.py migrate --noinput && cd ../..'
        leader_only: true

option_settings:
    - namespace: aws:elasticbeanstalk:container:python
      option_name: WSGIPath
      value: site/kpmkhv/wsgi.py
    - namespace: aws:elasticbeanstalk:container:python:staticfiles
      option_name: /static/
      value: site/kpmkhv/static/
    - option_name: DJANGO_SETTINGS_MODULE
      value: settings_prod

所以现在当我使用同一个实例并启动我的环境时，我收到有关依赖项的错误。

Error: Package: gdal-libs-1.9.2-5.rhel6.x86_64 (pgdg93)
            Requires: libpoppler.so.5()(64bit)
  You could try using --skip-broken to work around the problem
  You could try running: rpm -Va --nofiles --nodigest

看起来同一个 repo 现在正在返回更新版本的 poppler，它是 12.x，现在是 22.x，gdal 需要旧版本。

我还在 EC2 实例上对此进行了测试，但遇到了同样的错误。但后来我在 locking an AMI to its original repository version 上从亚马逊看到了这份文件.

因此，当您启动时通过 EC2 控制台将此添加到用户选项可修复 EC2 上的问题:

#cloud-config
repo_releasever: 2014.03

当您的 Beanstalk 代表您启动 EC2 实例时，始终拥有此选项的最佳方式是什么？我阅读了有关 cloud-init 的信息，也许通过 ebextensions 部署的脚本是最好的选择？

感谢任何对此的见解，谢谢。

我对 2017.03 图像的解决方案是:

commands:
  01_yum_update:
    command: sudo yum -y update
  02_epel_repo:
    command: sudo yum-config-manager -y --enable epel
  03_install_gdal_packages:
    command: sudo yum -y install gdal gdal-devel

files:
  "/etc/httpd/conf.d/wsgihacks.conf":
    mode: "000644"

    group: root
