执行 pm2 启动命令的 Ansible 错误

Question

使用命令执行ansible playbook时：ansible-playbook 2_installJsReport.yml

CentOS 7.6

Ansible 2.7.10

我收到一条错误消息：

TASK [make jsreport start at system restart] >*****************************************************************************>************************************** fatal: [localhost]: FAILED! => {"changed": true, "cmd": ["pm2", "startup"], >"delta": "0:00:00.601130", "end": "2019-04-24 12:59:33.091819", "msg": "non->zero return code", "rc": 1, "start": "2019-04-24 12:59:32.490689", "stderr": >"", "stderr_lines": [], "stdout": "[PM2] Init System found: systemd\n[PM2] To >setup the Startup Script, copy/paste the following command:\nsudo env >PATH=$PATH:/home/username/.nvm/versions/node/v8.11.3/bin >/home/username/.nvm/versions/node/v8.11.3/lib/node_modules/pm2/bin/pm2 >startup systemd -u username --hp /home/username", "stdout_lines": ["[PM2] >Init System found: systemd", "[PM2] To setup the Startup Script, copy/paste >the following command:", "sudo env >PATH=$PATH:/home/username/.nvm/versions/node/v8.11.3/bin >/home/username/.nvm/versions/node/v8.11.3/lib/node_modules/pm2/bin/pm2 >startup systemd -u username --hp /home/username"]}

Ansible 脚本

---
- hosts: localhost

  tasks:

    - name: make jsreport start at system restart
      command: pm2 startup

Answer 1

"error" 消息包含配置启动时应遵循的说明：

[PM2] Init System found: systemd
[PM2] To setup the Startup Script, copy/paste the following command: sudo env PATH=$PATH:/home/username/.nvm/versions/node/v8.11.3/bin /home/username/.nvm/versions/node/v8.11.3/lib/node_modules/pm2/bin/pm2 startup systemd -u username --hp /home/username

如果您按照这些说明进行操作，它会建议您将任务替换为类似以下内容：

---
- hosts: localhost

  tasks:

    - name: make jsreport start at system restart
      become: true
      command: pm2 startup systemd -u username --hp /home/username
      environment:
        PATH: "{{ ansible_env.PATH }}"
