I want to instal influxdb and configuration with ansible.我想用ansible安装influxdb和配置。 File copy and influxdb configuration is ok But creating database and user create section is give a "ansible_python_interpreter" error.
文件复制和 influxdb 配置没问题但是创建数据库和用户创建部分给出了“ansible_python_interpreter”错误。
I searched this error and tried something but I can't solve this problem with myself我搜索了这个错误并尝试了一些东西,但我自己无法解决这个问题

This worked for me.这对我有用。
- name: Install requests python package
pip:
name: requests
vars:
ansible_python_interpreter: /usr/bin/python3
There are 3 ways to solve this problem if you encounter it on your remote host:如果您在远程主机上遇到此问题,有 3 种方法可以解决此问题:
All 3 options can be done in Ansible, without sshing into the host.所有 3 个选项都可以在 Ansible 中完成,而无需 SSH 到主机。
example例子
- name: misc task on ubuntu 18.04 instance
hosts: "*"
vars:
ansible_python_interpreter: /usr/bin/python3
tasks:
- debug: var=ansible_host
Option 3 - Symlink /usr/bin/python -> /usr/bin/python3 using Ansible's raw module Another option in a similar vein to option 2 is to use the raw module to “symlink” /usr/bin/python -> /usr/bin/python3.选项 3 - 符号链接 /usr/bin/python -> /usr/bin/python3 使用 Ansible 的原始模块另一个与选项 2 类似的选项是使用原始模块来“符号链接” /usr/bin/python -> / usr/bin/python3.
With a bit of shell magic, we can fashion a command to do this conditionally based on whether either of the files exist using conditionals:使用一点 shell 魔法,我们可以根据两个文件是否存在使用条件来创建一个命令来有条件地执行此操作:
if [ -f /usr/bin/python3 ] && [ ! -f /usr/bin/python ]; then
ln --symbolic /usr/bin/python3 /usr/bin/python;
