我觉得我的代码中有不正确的地方，这导致ansible在永无止境的循环中运行它，并且不返回命令提示符。
我尝试启用调试模式“ export ANSIBLE_DEBUG = 1”，发现某些内容在不断循环中不断运行。
这是我的剧本代码：
- hosts: all
gather_facts: false
strategy: free
tasks:
- include_vars: roles/oracle/vars/install_vars.yaml
vars:
var_list:
- script_name
- set_fact:
ORACLE_HOMES_DIR: "/u01/app/oracle/product"
DB_HOME: "{{ ORACLE_HOMES_DIR }}/{{ ORACLE_VERSION }}/dbinst_1"
- name: Copy script to host
copy:
src: "{{ playbook_dir }}/{{ script_name }}"
dest: "/tmp/"
owner: "{{ USER_ORACLE }}"
group: "{{ GROUP_ORACLE }}"
mode: 0755
- name: Verify if the DB is open READ WRITE (or) not
become_user: "{{ USER_ORACLE }}"
environment:
ORACLE_SID: "{{ sid }}"
ORACLE_HOME: "{{ ORACLE_HOME }}"
shell: "echo \"set pagesize 0\n select trim(open_mode) from v\\$database;\" | {{ORACLE_HOME}}/bin/sqlplus -S / as sysdba"
with_items: "{{ hostvars[inventory_hostname]['sid_list'] }}"
loop_control:
loop_var: sid
register: om
- name: Get list of sid that are open in READ WRITE mode
set_fact:
sid_list: "{{ om.results | selectattr('sid','search','1$') | map (attribute='sid') | list }}"
- name: Get the OPEN MODE output of the sid's from the list
set_fact:
om_out: "{{ om.results | selectattr('stdout') | map (attribute='stdout') | list }}"
- name: execute sql script
become_user: "{{ USER_ORACLE }}"
environment:
ORACLE_SID: "{{ item.0 }}"
ORACLE_HOME: "{{ ORACLE_HOME }}"
shell: "{{ ORACLE_HOME }}/bin/sqlplus / as sysdba @/tmp/{{ script_name }}"
when: item.1 == 'READ WRITE'
with_together:
- "{{ sid_list }}"
- "{{ om_out }}"
它应该返回提示，如果我在一台主机上运行它，我的剧本可以正常工作，但是如果我在多台主机上循环访问，则我看到此问题。
这是我使用“ export ANSIBLE_DEBUG = 1”启用调试时看到的循环运行的内容：
