改變用戶和設置環境變量

使用ansible即時試圖 1.須藤到用戶ID - hduser 2.集合一些ENV變量 3.源文件。改變用戶和設置環境變量

後來，我打印ENV變量，但沒有看到ENV變量被設置爲用戶hduser

- 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

這些都是我的ENV變量，它沒有列出我的來源的。

Ansible中的每個任務都是分開處理的。

這樣，這是兩個獨立的任務：

- 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

而第二個任務一無所知的第一個。

您應該source並在單次運行執行命令：

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