download

Choose the appropriate installation package for your system version. This article installs CentOS 7

MongoDB's official website is https://www.mongodb.com/ , you can download the MongoDB program on the official website. The reason why it's a program is that the relevant programs of MongoDB in the downloaded installation package have been compiled. What I use is mongodb-linux-x86_64-3.6.4.tgz , you can select download from this page https://www.mongodb.com/download-center?jmp=nav#community.

[root@bigdata1 software]# cd /data/software/
[root@bigdata1 software]# wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.6.4.tgz

install and configure

Wait for the download to complete, unzip, and change the folder name to mongodb (optional)

[root@bigdata1 software]# tar -zxf mongodb-linux-x86_64-3.6.4.tgz
[root@bigdata1 software]# mv mongodb-linux-x86_64-3.6.4.tgz mongodb

Create database directory db, log directory logs and configuration file directory conf in mongodb directory

[root@bigdata1 software]# cd mongodb
[root@bigdata1 mongodb]# mkdir db
[root@bigdata1 mongodb]# mkdir logs
[root@bigdata1 mongodb]# mkdir conf
[root@bigdata1 mongodb]# ll

Create a new configuration file mogodb.conf under conf, and configure the following

[root@bigdata1 mongodb]# cd conf/
[root@bigdata1 conf]# touch mongodb.conf
[root@bigdata1 conf]# vi mongodb.conf 

Configuration content. If you are prompted that the nohttpinterface does not exist, comment it

#Port number, use default port

port = 27017

#Database directory

dbpath = /data/software/mongodb/db

#Log directory

logpath = /data/software/mongodb/logs/mongodb.log
logappend = true

#Whether to run as Daemons

fork = true

#Close http management interface or not


#nohttpinterface=true

Startup validation

start-up

To start mongodb, you need to use mongod in bin directory. If you specify the configuration file through - f or – config =, you need to

[root@bigdata1 conf]# cd /data/software/mongodb
[root@bigdata1 mongodb]# ./bin/mongod -f conf/mongodb.conf 
about to fork child process, waiting until server is ready for connections.
forked process: 6770
child process started successfully, parent exiting
[root@bigdata1 mongodb]# ps -ef | grep mongodb
root       6770      1 50 11:24 ?        00:00:51 ./bin/mongod -f conf/mongodb.conf
root       6800   1124  3 11:26 pts/0    00:00:00 grep --color=auto mongodb
