Install MongoDB 3.4 on yum in CentOS 7.

Step 1 check whether the yum source is configured for Mongodb

Switch to the yum directory cd/etc/yum. repos. d/

View File ls

The second part does not add the yum source.

Create File touch mongodb-3.4.repo

Edit this file vi mongodb-3.4.repo

Content:

Cat/etc/yum. repos. d/mongodb-3.4.repos

Mongodb-org-3.4

Name = MongoDB Repository

Baseurl = https://repo.mongodb.org/yum/redhat/?releasever/mongodb-org/3.4/x86_64/

Gpgcheck = 1

Enabled = 1

Gpgkey = https://www.mongodb.org/static/pgp/server-3.2.asc

You can modify gpgcheck = 0 to save gpg verification.

Update all packages before installation: yum update (optional)

Then install: yum install-y mongodb-org

View mongo installation location whereis mongod

View the modified configuration file vi/etc/mongod. conf.

Start cmdd: systemctl start cmdd. service

Stop mongod: systemctl stop mongod, service

Disable the firewall for Internet access:

CentOS 7.0 uses firewall as the firewall by default. Here, it is changed to iptables firewall.

Disable firewall:

Systemctl stop firewalld. service # stop firewall

Systemctl disable firewalld. service # disable firewall startup

Use mongodb: mongo 192.168.60.102: 27017

> Use admin

> Show dbs

> Show collections

After Mongodb is restarted, log on to the admin account and create a super privilege user.

Use admin

Db. createUser ({user: 'root', pwd: 'root', roles: [{"role": "root", "db": "admin"}]});

Configuration

Fork = true # Allow programs to run in the background

# Auth = true # Start Authentication

Logpath =/data/db/mongodb/logs/mongodb. log logappend = true # log writing mode: Set true to append. By default, dbpath =/data/db/mongodb/data/# data storage directory is overwritten.

Pidfilepath =/data/db/mongodb/logs/mongodb. pid # process ID. If it is not specified, no PID file is found at startup. Default.

# Bind_ip = 192.168.2.73 # bind an IP address. The default value is 127.0.0.1, which can only be set to true through local connection #. Modify the data directory storage mode. The files of each database are stored in different folders in the specified directory of DBPATH. # With this option, you can configure MongoDB to store data on different disk devices to increase write throughput or disk capacity. The default value is false. # It is recommended that you configure the option at the beginning.

Directoryperdb = true # disable logs # enable operation logs corresponding to journal to ensure the write persistence and data consistency. The journal directory is created under the dbpath directory.

Nojournal = true ##

Max connections # maximum number of connections. Default Value: Depends on the system (that is, the ulimit and file descriptor) restrictions. # MongoDB does not limit its own connections. If the setting is greater than the system limit, it is invalid. The system limit prevails. # Set the value to be greater than the connection pool and total connections to prevent connections during peak hours. # Note: The value cannot be greater than 20000. MaxConns = 1024
