1.ansible配置文件优先级

1.1 ansible默认配置文件说明

ansible配置文件 /etc/ansible/ansible.cfg 开头关于ansible配置文件优先级的说明

# config file for ansible -- https://ansible.com/
# ===============================================

# nearly all parameters can be overridden in ansible-playbook
# or with command line flags. ansible will read ANSIBLE_CONFIG,
# ansible.cfg in the current working directory, .ansible.cfg in
# the home directory or /etc/ansible/ansible.cfg, whichever it
# finds first

1.2 ansible配置文件优先级

ANSIBLE_CONFIG > 项目 > 用户家目录 > /etc/ansible/ansible.cfg

优先级第1(名为ANSIBLE_CONFIG的环境变量)

​ ANSIBLE_CONFIG

优先级第2(项目中)

​ ansible.cfg

优先级第3(用户家目录)

​ .ansible.cfg

优先级最低

​ /etc/ansible/ansible.cfg

1.3 ansible配置文件优先级示例

1.3.1 ansible初始读取的配置文件

ansible默认读取的配置文件，可以使用 ansible --version 命令查看，可以看到，ansible初始默认读取的是 /etc/ansible/ansible.cfg

$ ansible --version
ansible 2.9.16
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.5 (default, Apr  2 2020, 13:16:51) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]

1.3.2 优先级示例

手动指定 ANSIBLE_CONFIG 变量 ，然后查看ansible读取的配置文件

$ mkdir /root/ansible && touch /root/ansible/ansible.cfg
$ export ANSIBLE_CONFIG=/root/ansible/ansible.cfg
$ ansible --version
ansible 2.9.16
  config file = /root/ansible/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.5 (default, Apr  2 2020, 13:16:51) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]

创建项目，有时候我们不想把主机地址全部写在默认的主机清单 /etc/ansible/hosts中，这个时候就需要单独创建一些项目

⚠️注意需要进入项目中查看

$ mkdir /root/web_project/ && touch /root/web_project/ansible.cfg


# 不进入项目不生效
$ ansible --version
ansible 2.9.16
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.5 (default, Apr  2 2020, 13:16:51) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]

# 必须进入项目中查看
$ cd /root/web_project
$ ansible --version
ansible 2.9.16
  config file = /root/web_project/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.5 (default, Apr  2 2020, 13:16:51) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]

创建用户家目录下的 .ansible.cfg

$ touch .ansible.cfg0
$ ansible --version
ansible 2.9.16
  config file = /root/.ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.5 (default, Apr  2 2020, 13:16:51) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]
