如何设置MongoDB持久运行,以便我可以连接到它?
Depends on how you installed the MongoDB. 取决于你如何安装MongoDB。
If you used the whole apt-get
installation process, it generally installs an init.d
script and the whole thing just runs with the default settings. 如果您使用整个
apt-get
安装过程,它通常会安装一个init.d
脚本,整个过程只使用默认设置运行。
Try a ps -ef | grep mongod
试试
ps -ef | grep mongod
ps -ef | grep mongod
to look for the mongod
process. ps -ef | grep mongod
寻找mongod
进程。
If you "installed" by downloading the tar
file, then take a look at using upstart
or similar process for making it run persistently. 如果您通过下载
tar
文件“安装”,那么请查看使用upstart
或类似过程以使其持续运行。 You'll want to use config files. 你会想要使用配置文件。
How do I connect to a certain MongoDB database from within Node.js once it is up and running?
一旦启动并运行,我如何从Node.js中连接到某个MongoDB数据库?
Based on the Mongoose page , here is the basic connection process: 基于Mongoose页面 ,这是基本的连接过程:
var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/my_database');
The standard connection string format is detailed here . 标准连接字符串格式在此处详述。 Note that in my experience, not all drivers support all of the connection string features equally well, so do test your configuration.
请注意,根据我的经验,并非所有驱动程序都支持所有连接字符串功能,因此请测试您的配置。
