让我尝试解释我的需求：
作为我们应用程序常规部署的一部分，我们有一个SQL脚本（它将更改表，添加表或进行更新等），例如，该脚本需要在一个区域中的3个模式上运行，而在另一个区域中的5个模式上运行。该应用程序位于AWS中，数据库为Arora db（RDS）-MySQL。此架构可能需要30分钟到3个小时之间的任何时间。
此SQL脚本需要并行运行，并且每个模式运行之间要有2分钟的延迟。
这是我到目前为止所取得的成就：

conn_details:
- { host: localhost, user: root, password: "Password1!" }
- { host: localhost, user: root, password: "Password1!" }
- hosts: localhost
vars:
script_file: "{{ path }}"
vars_files:
- dbdata.yml
tasks:
- name: shell command to execute script in parallel
shell: |
sleep 30s
"mysql -h {{ item.host }} -u {{ item.user }} -p{{ item.password }} < {{ script_file }} >> /usr/local/testscript.log"
with_items: "{{ conn_details }}"
register: sql_query_output
async: 600
poll: 0
- name: Wait for sql execution to finish
async_status:
jid: "{{ item.ansible_job_id }}"
register: _jobs
until: _jobs.finished
delay: 20 # Check every 20 seconds. Adjust as you like.
retries: 10
with_items: "{{ sql_query_output.results }}"
第一部分-并行执行脚本，并且在每次执行之前还包括30秒的时间间隔。
第二部分-从注册的输出中选择可处理作业ID，并检查作业是否完成。
[请注意：在包含30秒的睡眠之前，此剧本运行良好。
我们在执行时有以下错误输出：
ansible-playbook parallel_local.yml --extra-vars "path=RDS_script.sql"

关于如何克服这一问题的任何建议。预先感谢您提供的所有帮助。
我不好。我犯了一个愚蠢的错误，正在制造麻烦。我需要从执行sql文件的行中删除“”。在下面复制正确的Yaml文件
- hosts: localhost
vars:
script_file: "{{ path }}"
vars_files:
- dbdata.yml
tasks:
- name: sample command- ansible-playbook my_sqldeploy.yml --extra-vars "path=/home/NICEONDEMAND/bsahu/RDS_create_user1.sql"
shell: |
sleep 30s
mysql -h {{ item.host }} -u {{ item.user }} -p{{ item.password }} < {{ script_file }} >> /usr/local/testscript.log
with_items: "{{ conn_details }}"
register: sql_query_output
async: 600
poll: 0
- name: Wait for creation to finish
async_status:
jid: "{{ item.ansible_job_id }}"
register: _jobs
until: _jobs.finished
delay: 20 # Check every 5 seconds. Adjust as you like.
retries: 10
with_items: "{{ sql_query_output.results }}"
非常感谢您的帮助。
