MongoDB Learning: MONGO Installation and remote access

One-click Installation via apt-get install MONGO under Linux MONGO

The configuration file for MONGO after installation is located in /etc/mongodb.conf. It 's inside . MONGO configuration, the file content is as follows: Important mainly have the following items:

1 DBPath: Where the database files are stored

2 logpath: where log is stored

3 Bind_ip = 127.0.0.1. When installed, only local access is allowed by default. The IP that restricts access is 127.0.0.1. If you want to allow all addresses to be accessed. You need to comment out this line

4 Port: Port number to access
