我正在尝试在 ansible playbook 中自动重置 kafka 流应用程序。 剧本正在做它需要做的事情。 但是，执行 playbook 中的重新启动任务时，应用程序不会重新启动。 流式应用程序作为 systemd 服务运行，因此我使用 ansible systemd 模块重新启动应用程序。
# Restart the application.
# - name: restart streaming application service
# systemd:
# name: "{{applicationId}}.service"
# state: restarted
# daemon_reload: yes
# become: yes
然而这并没有成功，应用程序也无法启动。 即使启用了跟踪，日志中也没有指示应用程序失败的原因。我只是看到状态开始从 REBLANCING 过渡到 PENDING_SHUTDOWN，然后在“通知关闭”
值得一提的是，如果我从 VM 手动重新启动服务，那么应用程序可以正常启动！！
感谢任何帮助！
