安装有蓝鲸的机器断电重启了怎么办？

断电重启，手动重启，人工误操作，机器死机，蓝鲸进程怎么办？

q.前提知识：

本文基于《如何安装蓝鲸的saas-o之bk_nodeman？》

https://blog.csdn.net/haoding205/article/details/82784686

1.引子：

在上文中，我们知道，快速部署蓝鲸，正在安装蓝鲸的saas-o之bk_nodeman时，发现第一台机器由于内存不足卡死，必须要重启，我们就要做好预案，重启后进程怎么办？

2.蓝鲸机器重启原理

机器重启后

确认 /etc/resolv.conf 里第一个nameserver是 127.0.0.1，option选项不能有rotate

检查重启机器的crontab，是否有自动拉起进程的配置 crontab -l | grep process_watch，重启后的自动拉起主要靠crontab

中控机上确认所有进程状态：./bkcec status all, 正常情况下应该都是正常拉起RUNNING状态，如果有EXIT的，则尝试手动拉起。手动拉起的具体方法参考组件的启动停止

如果社区版所有机器同时重启，很大概率会有很多进程启动失败，因为不同机器上组件恢复的时间没法控制，导致依赖的组件还没启动起来，导致失败，连锁反应。所以这种情况，遵循和安装时的启动原则:

先启动db
启动依赖的其他开源组件及服务
启动蓝鲸产品

如果已经部署过SaaS，那么手动拉起。

./bkcec start saas-o # 正式环境
  ./bkcec start saas-t # 测试环境

3.蓝鲸机器重启实践

3.1.确认机器有crontab任务存在

3.2.机器关机，增加内存

略

3.3.机器启动

静候应用进程被crontab定时任务自动拉起，然后检查效果：

4.结论

实践成功，重启后应用进程被crontab自动拉起了，经过脚本检测，所有进程启动正常，符合预期结果。

此时，我们可以回到《如何安装蓝鲸的saas-o之bk_nodeman？》

https://blog.csdn.net/haoding205/article/details/82784686

继续完成bk_nodeman的安装，直到100%完成并成功为止。
