如何在Ubuntu 16.04中自动重启Mongodb
[英]How to auto-restart Mongodb in Ubuntu 16.04
问题描述
I can't figure out how to auto-restart mongodb on Ubuntu 16.04 in the event that it crashes due to memory-pressure. 
我无法弄清楚如何在Ubuntu 16.04上因内存压力崩溃而自动重启mongodb。
I'm using supervisord for other scripts etc, but mongod is through systemctl and I'm not sure how that ties into it. 我正在使用supervisord用于其他脚本等，但mongod是通过systemctl而我不确定它是如何与它相关联的。

Figured it out: 弄清楚了：
- Edit your mongod service:
sudo vim /lib/systemd/system/mongod.service编辑你的mongod服务： sudo vim /lib/systemd/system/mongod.service - Add
Restart=alwaysunderservice添加Restart=always在service - Reload systemctl daemon:
sudo systemctl daemon-reload重新加载systemctl守护程序： sudo systemctl daemon-reload
Now whenever mongod gets killed. 现在每当mongod被杀。 It'll get respawned by systemctl. 它会被systemctl重生。

When you install mongoDB just run systemctl enable mongod.service on terminal. 当您安装mongoDB只需在终端上运行systemctl enable mongod.service 。
This will make your mongoDB service auto-start on every restart. 这将使您的mongoDB服务在每次重启时自动启动。
