我想在 bash 脚本中使用 ansible 的 Expect 工具。首先,执行我的 shell 脚本。检查$JAVA_HOME
变量。我设置了$JAVA_HOME
,但在 Ansible 中,我收到错误。
我env
的$JAVA_HOME
:
[root@portal bin]# env | grep JAVA
JAVA_HOME=/usr/java/jdk1.8.0_161
和我的外壳:
#!/usr/bin/expect -f
set timeout 1
spawn /opt/install.sh
expect "\[input\] Are you installing the application at the central data center? \[yes/no default: yes\]? \[yes\]\r"
send "yes\r"
expect "\[input\] What is the code of central data center \[default: 01\]? \[01\]\r"
send "01\r"
expect "What is ip or hostname of your server \[default: localhost\]? \[localhost\]\r"
send "portal\r"
我的剧本:
- name: --- run portal expect ---
shell: |
cd /opt/
chmod +x portal
./portal
Ansible 最后报错:
TASK [ansible-portal : --- run portal expect ---]
****************************************************************************************************
fatal: [portal]: FAILED! => {"changed": true, "cmd": "cd /opt/installer/bin/\n chmod +x portal\n ./portal", "delta": "0:00:00.015509", "end": "2018-07-07 14:01:57.971794",

照常运行脚本没有问题。
答案1
$JAVA_HOME
已为您的交互式 shell 设置,但是当您运行 Ansible playbook 时,您在远程服务器上运行该 playbook 的 shell 可能尚未设置$JAVA_HOME
。
不过对于 Ansible 来说这不是问题,只需在任务运行时将其设置为参数即可:
- name: --- run portal expect ---
shell: |
cd /opt/
chmod +x portal
./portal
environment:
JAVA_HOME: /usr/java/jdk1.8.0_161
