通过 Ansible 安装 Jenkins 时发现 Java 的版本不正确

Question

需要你的帮助，当我尝试通过 Ansible playbook 安装 Jenkins 时 returns 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)

真不知道从何说起。谢谢

Answer 1

Jenkins 现在需要 Java 8，您需要在此之前向您的 Ansible Playbook 添加一个任务，以确保您得到 Java 8。

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

您可能还想将正确的 Java link 设置为 OS 默认值，以防您最终使用以下代码进行多个安装。

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

如果您是运行来自角色的，则将其插入角色定义本身之前的 pre-tasks: 部分下。

你可以试试这个安装 java8:

- 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
