MongoDB has been widely used as a NoSQL Database in recent years. More and more enterprises are trying to use MongoDB instead of the original Database. MongoDB also performs well in clusters, sharding, and replication. I will introduce various MongoDB deployment experiments.
Preface
As a document-type NoSQL database,
one of the most foolish steps under Ubuntu ( below are the actions under the root user ): 1. Run "apt-get install MONGO"Run "apt-get update" If the installation package is not found2. You should automatically run the Mongod program after you install it, and see if the process has started with "pgrep mongo-l ".3. Enter "MONGO"in terminal, then enter the database(over)Here's how to start your own MongoDB pro
automatically started in the background.
Enter/usr/bin/and enter the following command:./Mongod -- dbpath/var/lib/mongodb/-- logpath/var/log/mongodb. log -- logappend Background running program
At this step, the Mongodb database has been installed.
Note:
How can I enable Mongodb extension in PHP?1. install php mongoSu
. Run the command: vi/etc/apt/sources. list. d/10gen. list (note that this command may require sudu permission. If you need sudo before vi, note the space between sudu and vi)
3. Insert the following command to 10gen. list:
Deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen
4. Save and exit vi
5. Run the command: sudo apt-get update
6. Run the command: sudo apt-get install mongodb-10gen
, switch to the root user in the console. Because the Default User in Ubuntu Desktop version does not have the highest level of permissions, switch to the root user in the console.
Specific Method:
In the Ubuntu Desktop Environment, click ctrl + alt + t to open the console, enter the command: sudo passwd root, and press enter to prompt "enter a new unix Password ", enter the password to generate a new root
