Installing MongoDB with Yum in CentOS

The following is an example of installing mongodb3.x. MongoDB formally provides PACKGE installation support, which includes the following packages in their warehouses:
Mongodb-org: This package will automatically install all of the following component packages
Mongodb-org-server: Contains Mongod, and related configuration and initial scripts
Mongodb-org-mongos: Includes MONGOs
Mongodb-org-shell: Contains MONGO scripts
Mongodb-org-tools: Contains the following MongoDB tools: Mongoimport Bsondump,mongodump,mongoexport,mongofiles,mongoplog,mongoperf, Mongorestore,mongostat and Mongotop.

1. Configure Yum

Create a yum warehouse file repo

Vi/etc/yum.repos.d/mongodb-org-3.2.repo1

The contents of the repo file are as follows:

[MongoDB]
Name=mongodb Repository
baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64/
gpgcheck=0
enabled=1

2. Installing MongoDB packages and related tools

To install all MONGODB components:

Yum Install-y mongodb-org1

You can also install the specified MongoDB components:

Yum install-y mongodb-org-3.2.5 mongodb-org-server-3.2.5 mongodb-org-shell-3.2.5 mongodb-org-mongos-3.2.5 mongodb-org-tools-3.2.51

After the installation is complete, to prevent accidental escalation, you can add the following configuration in/etc/yum.conf to prevent accidental escalation:

Exclude=mongodb-org,mongodb-org-server,mongodb-org-shell,mongodb-org-mongos,mongodb-org-tools1

3. Configure SELinux

There are 2 ways to view the SELinux status as follows:
Command 1:

/usr/sbin/sestatus-v 1

Command 2:

Getenforce1

There are 2 ways to turn off SELinux:
1. Temporarily shut down (without restarting the machine):
Command:

Setenforce 0 1

The above command sets SELinux to become permissive mode
Setenforce 1 setting SELinux to become enforcing mode

2. Modify the configuration file to restart the machine:
Modify the/etc/selinux/config file
Change selinux=enforcing to selinux=disabled or permissive
Restart the machine

4. Modify the data storage location

MongoDB defaults to prevent data files from/var/lib/mongo, and log files are stored in/var/log/mongodb. Modify the Systemlog.path and Storage.dbpath add information in the configuration file/etc/mongd.conf.

5. Start MongoDB

To start the MONGO service:

Systemctl Start Mongod1

Or

Service Mongod Start1

View the/var/log/mongdb/mongd.log file to see if there is a line below the log if there is a MONGO boot success.
[Initandlisten] Waiting for connections on port

The port number is configured in/etc/mongd.conf and defaults to 27017.

To configure boot boot:

Systemctl Enable Mongod1

Or

Chkconfig Mongod On1

6. Stop restarting MongoDB

To stop the MongoDB service:

Systemctl Stop Mongod1

Or

Service Mongod STOP1

To restart the MongoDB service:

Systemctl Restart Mongod1

Or

Service Mongod Restart1

7. Uninstalling MongoDB

To stop the MongoDB service:

Systemctl Stop Mongod1

Or

Service Mongod STOP1

To delete a previously installed MONGODB related package:

Yum Erase $ (rpm-qa | grep mongodb-org) 1

To delete a data folder:

sudo rm-r/var/log/mongodbsudo rm-r/var/lib/mongo12
