如何优雅向chatgpt提问ansible相关问题
使用ansible ,利用openssl 签发IP地址,要求: 1、有检测openssl 是否安装 2、环境是centos7 3、CA机构,邮箱,证书名称 这些通过变量维护 4、证书有效期10年
Ai.小助手: 下面是一个示例Playbook,可以使用Ansible和OpenSSL来签发IP地址的证书,并检查目标主机上是否安装了OpenSSL。同时,根据变量值生成证书和密钥,并将其复制到目标主机上。证书有效期为10年。

在上面的Playbook中,我们首先使用Ansible的stat模块检查目标主机上是否已经安装了OpenSSL。如果不存在,则使用yum模块安装OpenSSL。然后,我们使用openssl
使用ansible,要求: 1、下发脚本 2、执行脚本并输出到以服务器ip命名的文件中去 3、将文件拷贝到本地
为了实现你的要求,你可以使用 Ansible 的一些模块,例如 copy
, script
, fetch
和 shell
。这些模块可以帮你在目标服务器上分发脚本,执行脚本,并将结果保存在指定的文件中,然后将这些文件复制回本地。以下是一个示例的 Ansible playbook:
---
- hosts: your_target_hosts
gather_facts: no
tasks:
- name: 下发脚本到目标主机
copy:
src: /local/path/to/your/script.sh
dest: /remote/path/to/script.sh
mode: 0755
- name: 执行脚本并将输出存入以服务器IP命名的文件中
shell: /remote/path/to/script.sh > /remote/path/to/output/{{ inventory_hostname }}.txt
register: shell_output
- name: debug shell output
debug:
var: shell_output.stdout_lines
- name: 将文件拷贝回本地
fetch:
src: /remote/path/to/output/{{ inventory_hostname }}.txt
dest: /local/path/to/output/
flat: yes

在这个 playbook 中,your_target_hosts
是你的目标服务器,你需要在你的 inventory 文件中定义。/local/path/to/your/script.sh
是你要下发的脚本在本地的路径,/remote/path/to/script.sh
是这个脚本在目标服务器上的路径。然后使用 shell
模块执行这个脚本并将输出存入一个文件中,文件以服务器的 IP ()命名。最后,
fetch
模块会将这个文件复制回本地。
你需要将这个 playbook 保存为一个 .yml
或 .yaml
文件,然后使用以下命令运行它:
ansible-playbook your_playbook.yaml
注意,这个 playbook 假设你已经设置好了 SSH 公钥认证,因此你可以无密码登录到你的目标服务器。如果你还没有设置,你需要先设置 SSH 公钥认证。
