nstall MongoDB 3.4 process on yum\u00a0under\u00a0CentOS<\/a>\u00a07 system.<\/p>\n

The first step to see if there is a MongoDB configuration yum source<\/p>\n

Switch to the yum directory cd \/etc\/yum.repos.d\/<\/p>\n

View the file ls<\/p>\n

The second part does not exist to add yum source<\/p>\n

Create the file touch mongodb-3.4.repo<\/p>\n

Edit this file vi mongodb-3.4.repo<\/p>\n

content:<\/p>\n

Cat \/etc\/yum.repos.d\/mongodb-3.4.repos<\/p>\n

[mongodb-org-3.4]<\/p>\n

Name=MongoDB Repository<\/p>\n

Baseurl=https:\/\/repo.mongodb.org\/yum\/\u00a0RedHat<\/a>\u00a0\/$releasever\/mongodb-org\/3.4\/x86_64\/<\/p>\n

Gpgcheck=1<\/p>\n

Enabled=1<\/p>\n

Gpgkey=https:\/\/www.mongodb.org\/static\/pgp\/server-3.2.asc<\/p>\n

You can modify gpgcheck=0 here to save gpg verification<\/strong><\/p>\n

Update all packages before installation: yum update (optional operation)<\/p>\n

Then install: yum install -y mongodb-org<\/p>\n

Check the mongo installation location whereis mongod<\/p>\n

Check the modified configuration file: vi \/etc\/mongod.conf<\/p>\n

Start mongod :systemctl start mongod.service<\/p>\n

Stop mongod :systemctl stop mongod,service<\/p>\n

External network access needs to shut down the firewall:<\/strong><\/p>\n

CentOS 7.0 uses firewall as the firewall by default, and it is changed to iptables firewall.<\/p>\n

Close the firewall:<\/p>\n

Systemctl stop firewalld.service #stop firewall<\/p>\n

Systemctl disable firewalld.service #Disable firewall startup<\/p>\n

Use mongodb : mongo 192.168.60.102:27017<\/p>\n

>use admin<\/p>\n

>show dbs<\/p>\n

>show collections<\/p>\n

After restarting Mongodb, log in to the admin account and create a super-privileged user<\/p>\n

Use admin<\/p>\n

db.createUser({user:’root’,pwd:’root’,roles:[{ “role” : “root”, “db” : “admin” }]});<\/p>\n

Configuration<\/strong><\/p>\n

Fork=true ## allows programs to run in the background<\/p>\n

#auth=true ## Start Authentication<\/p>\n

Logpath=\/data\/db\/mongodb\/logs\/mongodb.log logappend=true # Write log mode: set to true to append.\u00a0The default is to override dbpath=\/data\/db\/mongodb\/data\/ ## data storage directory<\/p>\n

Pidfilepath=\/data\/db\/mongodb\/logs\/mongodb.pid # Process ID. If not specified, there will be no PID file when starting.\u00a0Default default.<\/p>\n

Port=27017<\/p>\n

#bind_ip=192.168.2.73 # Bind addresses.\u00a0The default is 127.0.0.1. You can only change the data directory storage mode by setting the local connection # to true. Each database file is stored in a different folder in the DBPATH specified directory.\u00a0# With this option, MongoDB can be configured to store data on different disk devices to increase write throughput or disk capacity.\u00a0The default is false.\u00a0# suggest to configure sub-options from the beginning<\/p>\n

Directoryperdb=true # Disable log # Enable the operation log for the journal to ensure write consistency and data consistency. Create a journal directory in the dbpath directory<\/p>\n

Nojournal = true ##<\/p>\n

Max connections # The maximum number of connections.\u00a0Default: Depends on system (ie ulimit and file descriptor) restrictions.\u00a0# MongoDB does not limit its own connection.\u00a0When the setting is greater than the system limit, it is invalid and the system limit prevails.\u00a0# Set the value of this value higher than the size of the connection pool and the total number of connections to prevent connections at peak times.\u00a0# Note: This value cannot be set greater than 20000.\u00a0maxConns=1024<\/p>\n","protected":false},"excerpt":{"rendered":"
