Mongodb -如何重新启动您刚刚在Linux中杀死的mongodb？

Question

如何重新启动我刚刚在Linux中杀死的mongodb？

杀人前：

$ service mongodb status
● mongodb.service - An object/document-oriented database
   Loaded: loaded (/lib/systemd/system/mongodb.service; disabled; vendor preset: enabled)
   Active: active (running) since Tue 2017-01-03 08:41:16 GMT; 4h 5min ago
     Docs: man:mongod(1)
 Main PID: 1036 (mongod)
    Tasks: 10
   Memory: 61.0M
      CPU: 1min 1.636s
   CGroup: /system.slice/mongodb.service
           └─1036 /usr/bin/mongod --config /etc/mongodb.conf

所以我想为其他程序停止/终止它一段时间：

$ sudo kill 1036
$ service mongodb status
● mongodb.service - An object/document-oriented database
   Loaded: loaded (/lib/systemd/system/mongodb.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:mongod(1)

但我怎样才能重新开始呢？

我在Ubuntu 16.04.

编辑：

$ systemctl start mongod 
Failed to start mongod.service: Unit mongod.service not found.

编辑2:

Get this error below when I have the other program running on mondodb. so I killed that program and it works as before.

$ sudo systemctl start mongodb
$ service mongodb status
● mongodb.service - An object/document-oriented database
   Loaded: loaded (/lib/systemd/system/mongodb.service; disabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Tue 2017-01-03 13:05:19 GMT; 9s ago
     Docs: man:mongod(1)
  Process: 21732 ExecStart=/usr/bin/mongod --config /etc/mongodb.conf (code=exited, status=48)
 Main PID: 21732 (code=exited, status=48)

Answer 1

Ubuntu 16.04 LTS

sudo systemctl start mongodb

不仅对于MongoDB，而且对于任何已安装的应用程序，您都可以使用

sudo systemctl start <app_name>
sudo systemctl restart <app_name>

Answer 2

似乎您正在使用systemd

尝试：

systemctl start mongod ->启动服务

systemctl status mongod ->服务状态

systemctl restart mongod ->重新启动服务

systemctl reload mongod ->重新加载服务
