Install a Simple Test Ops Manager Installation¶
Warning
This setup is not suitable for a production deployment.
To evaluate Ops Manager, you can install the Ops Manager Application and Ops Manager Application Database on a single host. This setup provides all the functionality of Ops Manager monitoring and automation but provides no failover or high availability.
Unlike a production installation, this test installation uses one
mongod
for the Ops Manager Application database. In production, the database
requires a dedicated replica set.
This procedure explains how to activate the Backup feature. This
optional step requires you to install Snapshot Storage on the
same host as the other Ops Manager components. You configure the backup
database as you would the application database, using one mongod
instead of a replica set.
To install and configure an evaluation version of Ops Manager on hosts running Red Hat Enterprise Linux 8.0:
Provision an Ops Manager host.¶
Provision a host for Ops Manager that meets the following requirements:
System Memory | 15 GB |
---|---|
Disk Capacity | 50 GB in / (The root directory of this host) |
Host OS Permissions | root |
Host OS | Red Hat Enterprise Linux 8.0 |
Using AWS
An AWS EC2 t3a.xlarge
instance meets the memory
requirements. Change the size of the instance’s root partition to
50 GB. Log in to the instance and execute df -h
to verify the
root partition has 50 GB of space.
Important
Ensure the ulimit
settings meet the minimum requirements.
For more information, see the MongoDB Ulimit Settings.
Configure yum
to install MongoDB.¶
Create a /etc/yum.repos.d/mongodb-org-4.4.repo
file so
that you can install MongoDB directly using yum
:
Install MongoDB.¶
Issue the following command to install the latest stable release of MongoDB:
Create the Ops Manager Application Database directory.¶
Issue the following two commands to create the data directory and change its ownership:
Update the MongoDB configuration file.¶
When you install MongoDB, it creates a configuration file saved at
/etc/mongod.conf
. Open this file with your preferred text editor.
Make the following changes to the file:
Save the file when you have made the edits.
Start the Ops Manager Application Database mongod instance.¶
Download the Ops Manager package.¶
- Navigate to the Ops Manager Download Center.
- From the Platforms drop-down menu, click Red Hat + CentOS 6, 7, 8 / SUSE 12 + 15 / Amazon Linux.
- From the Packages drop-down menu, click RPM.
- Click Download.
Note
The downloaded package is named
mongodb-mms-<version>.x86_64.rpm
, where <version>
is the
version number.
Optional: Copy the Ops Manager .rpm
package to your host.¶
If you are installing Ops Manager on a remote host, such as a cloud
provider compute instance, use scp
to copy the installer to your
host:
Install Ops Manager.¶
Install the .rpm
package by issuing the following command, where
<version>
is the version of the Ops Manager .rpm
package:
The install creates the following:
The base directory for the Ops Manager software, which is:
/opt/mongodb/mms/
A new system user,
mongodb-mms
, under which the host runs.The
/opt/mongodb/mms/conf/conf-mms.properties
file, which contains the connection string to access the Application Database inmongo.mongoUri
setting. The default value islocahost
, port27017
, so no changes are necessary.
Start Ops Manager.¶
Issue the following command:
Get your instance hostname.¶
If you are using an EC2 instance, the hostname is the Public DNS
listed on the EC2 instance’s Description
tab.
If you do not have a hostname, you can instead use the public IP address. To get the public IP address, paste this URL into your preferred browser:
Open the Ops Manager home page and register the first user.¶
In a browser, enter the following URL using the hostname. If do not have a hostname, use the public IP address instead:
Click the Register link and follow the prompts to register the first user and create the first project. The first user is automatically assigned the Global Owner role.
