Mongo DB is a non-relational database (NOSQL) that is currently very popular in the IT industry, and its flexible data storage methods are highly favored by current it practitioners. Mongo DB is a good implementation of object-oriented thinking (Oo idea), in Mongo db each record is a document object. The biggest advantage of Mongo DB is that all data persistence requires no developers to write SQL statements manually, and it is easy to invoke methods to implement CRUD operations. This article describes how to quickly install MongoDB for everyone's reference.
First, install the configuration MongoDB
Step 1: Set up the system environment and ensure that the default port 27107 is available
# # #当前环境
# 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 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: Unzip the downloaded file
# pwd
/usr/local/src
# TAR-XVF mongodb-linux-x86_64-rhel62-3.0.6.gz # # #注, this article is downloaded directly from the website, so the file is. gz
Step 4: Copy the extracted files 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: Setting 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 Catalog
# mkdir-p/data/mongodata
Second, start and verify MongoDB
# # #启动mongo
# Mongod--dbpath/data/mongodata
# # #以下内容为启动后输出的相关信息
