使用ansible进行Apt安装

Question

我使用ansible脚本在亚马逊EC2和一个流浪箱中设置我的环境(Ubuntu)。然后，我尝试在GermanVPS (Ubuntu Minimal)上设置相同的环境。使用Apt安装软件包似乎不起作用。

我跑步

ansible-playbook -i ansible/live -u priidu ansible/caselaw.yml -s -vvvv --start-at-task="install"

这会给出以下错误。

failed: [master] => (item=postgresql-9.4,postgresql-contrib-9.4,postgresql-server-dev-9.4,python-psycopg2) => {"failed": true, "item": "postgresql-9.4,postgresql-contrib-9.4,postgresql-server-dev-9.4,python-psycopg2"}
stderr: E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem. 

msg: '/usr/bin/apt-get -y -o "Dpkg::Options::=--force-confdef" -o "Dpkg::Options::=--force-confold"   install 'postgresql-server-dev-9.4' 'python-psycopg2'' failed: E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem. 


FATAL: all hosts have already failed -- aborting

然后我试一试

ansible-playbook -i ansible/live -u priidu ansible/caselaw.yml -s -vvvv --start-at-task="dpkg configure"

我得到了以下错误信息

failed: [master] => (item=postgresql-9.4,postgresql-contrib-9.4,postgresql-server-dev-9.4,python-psycopg2) => {"failed": true, "item": "postgresql-9.4,postgresql-contrib-9.4,postgresql-server-dev-9.4,python-psycopg2", "parsed": false}

FATAL: all hosts have already failed -- aborting

那里发生了什么?我该如何开始解决这个难题？

编辑:我的攻略的相关部分

- name: dpkg configure
  shell: dpkg --configure -a

- name: install
  apt: name={{ item }} update_cache=yes
  with_items:
    - postgresql-9.4
    - postgresql-contrib-9.4
    - postgresql-server-dev-9.4
    - python-psycopg2

编辑2:添加了攻略命令。

编辑3:当我将RAM从64MB增加到512MB时，这个问题消失了。

Answer 1

当我尝试通过ansible-playbook安装docker时，我遇到了这个问题。

我试着把内存从512Mb增加到1024Mb。但它并没有起作用。

然后我找到了如下解决方案：

删除/var/lib/dpkg/update中的所有文件，然后重试!！

无论如何，它对我来说是有效的！

Answer 2

我添加了一些任务来消除Ubuntu 16.04的dpkg问题，它工作得很好

tasks:
- name: configure dpkg 1
  command: sudo rm /var/lib/apt/lists/lock
  become: true

- name: configure dpkg 2
  command: sudo rm /var/cache/apt/archives/lock
  become: true

- name: configure dpkg 3
  command: sudo rm /var/lib/dpkg/lock  
  become: true

- name: configure dpkg 4
  command: sudo dpkg --configure -a
  become: true

- name: Update and upgrade apt packages 
  become: true
  apt:
    upgrade: yes
    update_cache: yes
    cache_valid_time: 86400 #One day

Answer 3

Ansible中有一个yum模块，可用于安装软件包。我被困了一段时间，因为我发现我必须安装其他依赖项，例如解压缩。但这对保持我的代码优雅和简单非常有用。

此链接提供模块的文档：

例如，要安装最新版本的Apache，请执行以下操作：

yum: name=httpd state=latest
