MongoDB replica set shard (i)---initialize MongoDB installation start

Written in front: MongoDB is a nosql non-relational database, a more popular product. In the data persistence and the association with the relational database is also done better, at present, the major companies in the storage of binary files (pictures, video, etc.) are widely used. It is also relatively simple to follow the Key-value data schema and object-oriented JSON statement usage. After that, I will share with you some of the experiences I have used in the learning and production applications of MongoDB. We hope that we will study together and explore together. Thank you.

The following is a simple shell scripted edit of the entire MongoDB installation process. Very simple script writing. If you have any questions, please feel free to contact me with feedback. In the process of use, you can paste the entire content into a text script similar to mongodbinit.sh. chmod Modify Permissions +x. Then execute.

Note: Replset is the name of the replica set, and you can freely edit the settings, using Replset=picture in this example. When you use Db.shutdownserver () to close the DB, only local connections are accepted.
