通过Ansible安装Jenkins时发现Java版本不正确

Question

需要您的帮助，当我试图通过Ansible playbook安装Jenkins时，它返回以下问题

Extracting templates from packages: 100%
Found an incorrect Java version
Java version found:
java version "1.7.0_131"
OpenJDK Runtime Environment (IcedTea 2.6.9) (7u131-2.6.9-0ubuntu0.14.04.2)
OpenJDK 64-Bit Server VM (build 24.131-b00, mixed mode)

Aborting
invoke-rc.d: initscript jenkins, action "start" failed.
dpkg: error processing package jenkins (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 jenkins
E: Sub-process /usr/bin/dpkg returned an error code (1)

我真的不知道从哪里开始。谢谢

Answer 1

您可以在安装java8时尝试以下方法：

- name: Ensure the webupd8 launchpad apt repository key is present
  apt_key:
    id: 0xC2518248EEA14886
    keyserver: keyserver.ubuntu.com
    state: present

- name: Add Oracle Java Repository
  apt_repository:
    repo: 'ppa:webupd8team/java'

- name: Accept Java 8 License
  debconf:
    name: 'oracle-java8-installer'
    question: 'shared/accepted-oracle-license-v1-1'
    value: 'true'
    vtype: 'select'

- name: Install Oracle Java 8
  apt:
    name: {{item}}
    state: latest
  with_items:
    - oracle-java8-installer
    - ca-certificates
    - oracle-java8-set-default

Jenkins现在需要Java8，在此之前，您需要在Ansible Playbook中添加一个任务，以确保Java8已经就位

- name: Install jdk version 8
  package:
    name: openjdk-8-jdk
    state: present

您可能还希望将正确的Java链接设置为操作系统默认值，以防您在几个安装到位的情况下使用以下代码结束

- name: Select openjdk 8 as system default java
    alternatives:
    name: java
    path: /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java

如果您是从角色运行此命令，请将其插入到角色定义本身之前的pre-tasks:节中
