This article introduces how to use yum to install mongodb in centos, the content is very detailed, interested friends can refer to, hope to be helpful to you.

1. Configure yum

Create a yum warehouse file repo

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

The repo file is as follows:

[mongodb]

Name=MongoDB Repository

Baseurl= http://downloads-distro.mongodb.org/repo/redhat/os/x86_64/

Gpgcheck=0

Enabled=1

two。 Install the MongoDB package and related tools

Install all mongodb components:

Yum install-y mongodb-org

You can also install 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-3.2.5

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

Exclude=mongodb-org,mongodb-org-server,mongodb-org-shell,mongodb-org-mongos,mongodb-org-tools3. Configure SELinux

There are two ways to check the SELinux status as follows:

Command 1:

/ usr/sbin/sestatus-v

Command 2:

Getenforce

There are two ways to turn off SELinux:

1. Temporary shutdown (no need to restart the machine):

Command:

Setenforce 0

The above command sets SELinux to permissive mode

Setenforce 1 sets SELinux to enforcing mode

two。 Restarting the machine is required to modify the configuration file:

Modify / etc/selinux/config file

Change SELINUX=enforcing to SELINUX=disabled or permissive

Just restart the machine.

4. Modify data storage location

By default, mongodb prevents data files from being stored in / var/lib/mongo and log files in / var/log/mongodb. Modify the systemLog.path and storage.dbPath add information in the configuration file / etc/mongd.conf.

5. Start mongodb

Start the mongo service:

Systemctl start mongod

Or

Service mongod start

Check the / var/log/mongdb/mongd.log file to see if there is a log on the following line. If so, it means that mongo started successfully.

[initandlisten] waiting for connections on port

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

Configure boot up:

Systemctl enable mongod

Or

Chkconfig mongod on6. Stop restarting mongodb

Stop the mongodb service:

Systemctl stop mongod

Or

Service mongod stop

Restart the mongodb service:

Systemctl restart mongod

Or

Service mongod restart7. Uninstall mongodb

Stop the mongodb service:

Systemctl stop mongod

Or

Service mongod stop

Remove the packages related to the previously installed mongodb:

Yum erase $(rpm-qa | grep mongodb-org)

Delete the data folder:

Sudo rm-r / var/log/mongodbsudo rm-r / var/lib/mongodb on how to use yum in centos to install mongodb is shared here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
