如何使用ansible终止正在运行的进程?

您可以忽略上的错误 wait_for

- name: Get running processes
  shell: "ps -ef | grep -v grep | grep -w {{ PROCESS }} | awk '{print $2}'"
  register: running_processes

- name: Kill running processes
  shell: "kill {{ item }}"
  with_items: "{{ running_processes.stdout_lines }}"

- wait_for:
    path: "/proc/{{ item }}/status"
    state: absent
  with_items: "{{ running_processes.stdout_lines }}"
  ignore_errors: yes
  register: killed_processes

- name: Force kill stuck processes
  shell: "kill -9 {{ item }}"
  with_items: "{{ killed_processes.results | select('failed') | map(attribute='item') | list }}"

使用 pkill (1) 而不是 grep kill .

这个 killall

安装psmisc:

tasks:
  - apt: pkg=psmisc state=present

tasks:
  - shell: "killall screen --wait"
    ignore_errors: true # In case there is no process

-w, --wait

ansible_linter ,低于替代方式(例如,不使用 ignore_error

- name: "disable and stop PROCESS"
  service:
    name: PROCESS
    enabled: no
    state: stopped
  tags:
    - stop

- name: "evaluate running PROCESS processes from remote host"
  command: "/usr/bin/pgrep PROCESS"
  register: running_PROCESS
  failed_when: running_PROCESS.rc > 1
  changed_when: 
    - running_PROCESS.rc == 0
  tags:
    - stop

- name: "pkill PROCESS running processes"
  command: "/usr/bin/pkill PROCESS"
  register: kill_PROCESS
  changed_when: kill_PROCESS.rc == 0
  when: running_PROCESS.stdout_lines | length > 0
  tags:
    - stop

- name: "check PROCESS processes"
  wait_for:
    path: "/proc/{{ item }}/status"
    state: absent
  with_items: "{{ running_PROCESS.stdout_lines }}"
  when: running_PROCESS.stdout_lines | length > 0
  tags:
    - stop

- name: "force kill stuck PROCESS processes"
  command: "/usr/bin/pkill -9 PROCESS"
  register: kill9_PROCESS
  changed_when: kill9_PROCESS.rc == 0
  failed_when: kill9_PROCESS.rc > 1
  when:
    - running_PROCESS.stdout_lines | length > 0
  tags:
    - stop
