Cenos7 yum how to install mongodb and what is the solution to startup errors, I believe that many inexperienced people do not know what to do, so this article summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

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

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

View the file ls

There is no add yum source in part II.

Create a file touch mongodb-3.4.repo

Edit the file vi mongodb-3.4.repo

Content:

[mongodb-org-3.4] name=MongoDB Repositorybaseurl= https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.4/x86_64/gpgcheck=1enabled=1gpgkey=https://www.mongodb.org/static/pgp/server-3.2.asc

Gpgcheck=0 can be modified here to omit gpg verification

Then install: yum install-y mongodb-org

View mongo installation location whereis mongod

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

Start mongod: systemctl start mongod.service

Stop mongod: systemctl stop mongod,service

To access the public network, you need to disable the firewall:

CentOS 7.0 uses firewall as the firewall by default, which is changed to iptables firewall here.

Turn off firewall:

Systemctl stop firewalld.service # stop firewall

Systemctl disable firewalld.service # prevents firewall from booting

Use mongodb: mongo localhost:27017

> use admin

> show dbs

> show collections

After restarting Mongodb, log in to the admin account and create a super privileged user

Use admin

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

Solution to startup errors: (for MongoDB installed with yum only) chown-R mongod:mongod / var/lib/mongochown-R mongod:mongod / var/log/mongodbrm / var/run/mongodb/mongod.pid-f

The following error occurred when starting mongodb:

Chown root:root / tmp

Chmod 777 / tmp

Error: pymongo.errors.ServerSelectionTimeoutError: 123.207.61.85 pymongo.errors.ServerSelectionTimeoutError 27017: [WinError 10061] unable to connect due to active refusal of the target computer.

Resolve:

Modify configuration vim / etc/mongodb.conf
