Yum installation and installation of MongoDB 3.4 under CENTOS7 system

Yum installation and installation of MongoDB 3.4 under CENTOS7 system

The first step is to see if there is a MongoDB configuration yum source

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

View File ls

The second part does not exist add Yum source

Create a file Touch Mongodb-3.4.repo

Edit the 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

Here you can modify the gpgcheck=0, eliminating the GPG verification

Update all packages before installing: Yum update (optional operation)

Then install: Yum install-y mongodb-org

View MONGO installation location Whereis Mongod

View Modify Profile: vi/etc/mongod.conf

Start Mongod:systemctl start Mongod.service

Stop Mongod:systemctl Stop Mongod,service

External network access requires the firewall to be turned off:

CentOS 7.0 defaults to using firewall as the firewall, where the iptables firewall is changed.

Close firewall:

Systemctl Stop Firewalld.service #停止firewall

Systemctl Disable Firewalld.service #禁止firewall开机启动

Using Mongodb:mongo 192.168.60.102:27017

>use Admin

>show DBS

>show Collections

After you restart MongoDB, login to the admin account to create a super-privileged user

Use admin

Db.createuser ({User: ' root ', pwd: ' Root ', roles:[{"role": "Root", "db": "Admin"}]});

Configuration

Fork=true # # Allows programs to run in the background

#auth =true # # Start Certification

Logpath=/data/db/mongodb/logs/mongodb.log logappend=true # Write Log mode: set to True for append. The default is to overwrite the dbpath=/data/db/mongodb/data/# # data store Directory

PIDFILEPATH=/DATA/DB/MONGODB/LOGS/MONGODB.PID # Process ID, no PID file is started when it is not specified. Default defaults.

port=27017

#bind_ip =192.168.2.73 # bind address. By default, 127.0.0.1 can only be set to true via local connection # to modify the data directory Storage mode, and each database file is stored in a different folder DBPath the specified directory. # with this option, MongoDB can be configured to store data on different disk devices to increase write throughput or disk capacity. The default is False. # It is recommended to configure the secondary option at the beginning

Directoryperdb=true # Disable log # corresponding to journal enable action log to ensure write persistence and data consistency, create journal directory in DBPath Directory

Nojournal = true # #

Max Connections # Maximum number of connections. Default value: Depends on the system (that is, the Ulimit and file descriptor) limits. # MongoDB does not restrict its own connections. When the setting is greater than the system limit, it is not valid, whichever is the system limit. # Set the value above the size of the connection pool and the total number of connections to prevent spikes in the connection. Note: You cannot set this value to greater than 20000. maxconns=1024
