Shell脚本执行在远程服务器Ansible中不起作用（先前的任务已成功执行）

标签： shell ansible

我无法在Ansible中远程执行Shell脚本。但是，在远程服务器中成功执行了具有相同角色（文件拍子）的先前任务。我正在本地服务器172.28.28.6服务器中运行以下命令，以在远程服务器172.28.28.81中安装并运行filebeat

剧本：install-filebeat.yml： 

 hosts: filebeat-servers
  remote_user: wwwadm
  sudo: yes
  roles:
  - { role: /vagrant/roles/filebeat}

角色文件拍子：main.yml： 

---
# tasks file for filebeat
- name: "Extract Filebeat"
  unarchive:
    src: "{{ tmp_artifact_cache }}/{{ filebeat_archive }}"
    remote_src: yes
    dest: "{{ filebeat_root_dir }}"
    extra_opts: ['--transform=s,/*[^/]*,{{ filebeat_ver }},i', '--show-stored-names']
  become: yes
  become_user: "{{ filebeat_install_as }}"
  when: not ansible_check_mode 
  tags: [ 'filebeat' ]

- name: Configure Filebeat
  template: 
    src: "filebeat.yml.j2"
    dest: "{{ filebeat_install_dir }}/filebeat.yml"
    mode: 0775
  become: yes
  become_user: "{{ filebeat_install_as }}"
  tags: [ 'filebeat' ]

- name: 'Filebeat startup script'
  template: 
    src: "startup.sh.j2" 
    dest: "{{ filebeat_install_dir }}/bin/startup.sh" 
    mode: 0755
  become: yes
  become_user: "{{ filebeat_install_as }}"
  tags: [ 'filebeat', 'start' ]

#This one does not get executed at all:
- name: "Start Filebeat"
  # shell: "{{ filebeat_install_dir }}/bin/startup.sh"
  command: "sh {{ filebeat_install_dir }}/bin/startup.sh"
  become: yes
  become_user: "{{ filebeat_install_as }}"

默认值： 

# defaults file for filebeat
filebeat_ver: "6.6.0"
filebeat_archive: "filebeat-{{ filebeat_ver }}-linux-x86_64.tar.gz"
filebeat_archive_checksum : "sha1:d38d8fea7e9915582720280eb0118b7d92569b23"

filebeat_root_dir: "{{ apps_home }}/filebeat"
filebeat_data_dir: "{{ apps_data }}/filebeat"
filebeat_log_dir: "{{ apps_logs }}/filebeat"
filebeat_install_dir: "{{ filebeat_root_dir }}/{{ filebeat_ver }}"

filebeat_cert_dir: "/etc/pki/tls/certs"
filebeat_ssl_certificate_file: "logstash.crt"
filebeat_ssl_key_file: "logstash.key"

filebeat_install_as: "{{ install_user | default('wwwadm') }}"

filebeat_set_as_current: yes
filebeat_force_clean_install: no

filebeat_java_home: "{{ sw_home }}/jdk"

库存/本地/主机： 

localhost ansible_connection=local

[filebeat-servers]
172.28.28.81 ansible_user=vagrant ansible_connection=ssh

已安装Filebeat，并在远程服务器中进行了更改，除了最后一步是执行Shell脚本之外

按以下方式运行剧本时：

ansible-playbook -i /vagrant/inventory/local install-filebeat.yml -vvv

获取与shell执行相关的以下输出：

通过执行ps命令找不到正在运行的进程

[bin:vagrant]$ ps -fea | grep filebeat | grep -v grep

但是，如果我连接到远程服务器，则可以通过使用用户wwwadm执行脚本来运行filebeat，并且filebeat成功启动：

[bin:wwwadm]$ pwd

[bin:wwwadm]$ id

您应该使用nohup在后​​台运行它。

  

因为当ansible退出时，与会话相关的所有进程   将终止。为避免这种情况，您应该使用nohup。

正确的命令是：

- name: "Start Filebeat"
  # shell: "{{ filebeat_install_dir }}/bin/startup.sh"
  command: "nohup sh {{ filebeat_install_dir }}/bin/startup.sh &>> startup.log &"
  become: yes
  become_user: "{{ filebeat_install_as }}"

答案 1 :(得分：0)

您必须使用disown内置命令来通知Shell断开连接时，它不应杀死后台进程；您也可以使用nohup来达到相同的效果

话虽如此，您肯定正在解决错误的问题，因为如果^ H ^ H在文件拍打失败时，没有任何监视该服务的方法来保持它的生命。您将要使用systemd（或系统上的等效文件）来确保filebeat保持运行，并且通过使用针对该内容设计的机制，您回避了导致您提出S.O的所有“ disown or nohup”业务。问题。
