Question

使用ansible im尝试 1. sudo进入用户id - hduser 2.设置一些env变量 3.获取文件。

稍后，我打印env变量，但没有看到为用户hduser设置的env变量

- name: change to hduser
  shell: sudo su - hduser

- name: Setting 
  lineinfile: 
    dest: /home/hduser/.bashrc 
    line: 'export HADOOP_HOME=/usr/local/hadoop' 
    insertafter: 'EOF' 
    regexp: 'export HADOOP_HOME=/usr/local/hadoop' 
    state: present

- name: Adding the path in the bashrc files
  lineinfile: 
    dest: /home/hduser/.bashrc 
    line: 'export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64' 
    insertafter: 'EOF' 
    regexp: 'export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64' 
    state: present

- name: Adding the path in the bashrc files
  lineinfile: 
    dest: /home/hduser/.bashrc 
    line: 'export PATH=$PATH:$HADOOP_HOME/bin' 
    insertafter: 'EOF' 
    regexp: 'export PATH=\$PATH:$HADOOP_HOME/bin' 
    state: present

- name: Source the bashrc file
  shell: source /home/hduser/.bashrc 
  register: sourcevar
  args:
    executable: /bin/bash

- debug:
    var: sourcevar
- name: print env variables
  shell: sudo su hduser && env
  register: envvar
  args:
    executable: /bin/bash

- debug: 
    var: envvar

这些是我的env变量，它没有列出我提供的变量。

Ansible中的每项任务都是单独处理的。

这样，这是两个独立的任务：

- name: Source the bashrc file
  shell: source /home/hduser/.bashrc 
  register: sourcevar
  args:
    executable: /bin/bash

- name: print env variables
  shell: sudo su hduser && env
  register: envvar

第二项任务对第一项任务一无所知。

你应该source并在一次运行中执行命令：

- shell: source /home/hduser/.bashrc; env
  args:
    executable: /bin/bash

更改用户和设置env变量
