我有一个500+目标服务器,在不同的位置安装了一个与ansible兼容的python version 2.7,如下所示。
/usr/bin/python /opt/app/xerto/tools/ansible/bin/python2.7 /opt/atlassian/tools/ansible/bin/python2.7 /opt/wsp/app/ansible/python2.7/bin/python2.7 /opt/wsp/apps/tools/ansible/python2.7/bin/python2.7 /opt/docs/python/bin/python2.7 /home/admin/ansible/bin/python2.7 /opt/operations/Python-2.7.8/bin/python /opt/ora/python/bin/python2.7 /opt/tomcat/tools/ansible/bin/python2.7
每次我必须在ansible主机文件中为ansible_python_interpreter设置上面的python路径时,取决于我的ansible要连接的目标服务器。
我的意图是在目标服务器上很少或不做任何更改,而在ansible端处理这个问题。
有没有一种聪明的方法可以让ansible知道想要的python在哪里?
请建议一下。

- hosts: all

gather_facts: no
vars:
possible_pythons:
- /usr/bin/python

tasks:
- raw: if [ -x "{{ item }}" ]; then echo "{{ item }}"; fi
with_items: "{{ possible_pythons }}"
register: pystat
when: pystat is not defined or (pystat.stdout|length) == 0
- set_fact:
ansible_python_interpreter: '{{ pystat.results | selectattr("stdout") | map(attribute="stdout") | first }}'
# NOW we can run the fact gathering step
- setup:

msg: and now we are off to the races!我认为当然也可以使用shell迭代来做到这一点,但我没有测试它,也没有仔细考虑所有的边缘情况:
- raw: |
PYTHONS='{{ possible_pythons | join(" ") }}'
for p in $PYTHONS; do
if [ -x "$p" ]; then echo "$p"; break; fi
done
