Ansible 剧本，设置环境变量不起作用

Question

我必须将 psycopg 安装到旧的 python (2.4)。一切正常，除了设置环境变量 -> LD_LIBRARY_PATH.

- name: install psycopg
  shell: "{{ item }}"
    environment:
      CPPFLAGS: "-I/my_python/lib/python2.4/site-packages/mx/DateTime/mxDateTime"
      LD_LIBRARY_PATH: "/path_to_postgresql/lib"
  args:
    chdir: "/path_to_psycopg_src/"
  with_items:
    - ./configure --prefix=/my_python --with-python=/my_python/bin/python --with-postgres-libraries=/path_to_postgresql/lib --with-postgres-includes=/path_postgresql/include --with-mxdatetime-includes=/my_python/lib/python2.4/site-packages/mx/DateTime/mxDateTime
    - make
    - make install

安装成功后出现以下错误：

>>> import psycopg
    ImportError: libpq.so.4: cannot open shared object file: No such file or directory

当我手动导出时，它工作正常：

export LD_LIBRARY_PATH="/path_postgresql/lib"
>>> import psycopg
>>> psycopg
<module 'psycopg' from '/my_python/lib/python2.4/site-packages/psycopgmodule.so'>

因为您设置 LD_LIBRARY_PATH 只是为了 install psycopg 任务。如果你想设置一个环境变量而不仅仅是 task/playbook 我认为你需要编辑 /etc/environment

Ansible 剧本，设置环境变量不起作用

Ansible playbook, set environment variables not working

python

ansible

ansible-playbook
