ansible 添加 cron 任务
找到相应的role, 假设以storm_nimbus为例,将要完成的任务脚本放在files目录下。
例如:vim roles/storm_nimbus/files/storm-recovery
#!/bin/bash service=storm-mesos if (( $(ps -ef | grep -v grep | grep $service | wc -l) > 3 )); then echo "`date`: $service are running!!!" else echo "`date`: $service are starting..." systemctl start storm-mesos-nimbus systemctl start storm-ui systemctl start storm-drpc #上面三条也可以合成一条: #systemctl start storm-{mesos-nimbus,ui,drpc} echo "`date`: $service are started!" fi
添加ansible task
--- - name: Deploy storm recovery script copy: src=storm-recovery dest=/usr/bin/storm-recovery mode=0755 tags: guard - name: Add cron job for storm recovery cron: name="storm recovery" job="/usr/bin/storm-recovery" minute=*/5 state=present tags: guard
将该task任务加入到main.yml中 roles/storm_nimbus/tasks/main.yml
- include: guard.yml
