Quick install of MongoDB in Linux

Quick install of MongoDB in Linux

MongoDB is a non-relational database (NoSql) that is very popular in the IT industry. Its flexible data storage method is favored by current IT practitioners. MongoDB implements the object-oriented idea (OO idea), and each record in MongoDB is a Document object. The biggest advantage of MongoDB is that all data persistence operations can easily implement CRUD operations without the need for developers to manually write SQL statements. This article describes how to quickly install mongodb for your reference.

1. install and configure mongodb
Step 1: set the system environment and make sure the default port 27107 is available
### Current Environment
# Cat/etc/issue
Red Hat Enterprise Linux Server release 6.5 (Santiago)

# Vi/etc/selinux/config
SELINUX = disabled

Step 2: Download the Installation File
: Https://www.mongodb.org/downloads.
Or you can use the curl command directly at the command prompt to download
Curl-O https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.0.6.tgz

Step 3: Decompress the downloaded file
# Pwd
/Usr/local/src
# Tar-xvf mongodb-linux-x86_64-rhel62-3.0.6.gz.

Step 4: Copy and decompress the file to the running directory
# Mkdir-p/var/lib/mongodb
# Cp-R-n/usr/local/src/mongodb-linux-x86_64-rhel62-3.0.6/./var/lib/mongodb/

Step 5: Set Environment Variables
E.g. export PATH = <mongodb-install-directory>/bin: $ PATH
# Vi ~ /. Bash_profile
Export PATH =/var/lib/mongodb/bin: $ PATH
# Source ~ /. Bash_profile

Step 6: create a data directory
# Mkdir-p/data/upload data

Ii. Start and verify mongodb
### Start mongo
# Mongod -- dbpath/data/mongodata

### The following information is output after startup

### Fix the two warnings during the startup process. ignore the warnings about using the root user to start mongo.

### Restart the instance and then place it in the background process,
# Mongod -- dbpath/data/mongodata &
